A physician orders a Heparin drip at 8.0 units per kg of body weight per hour via IV pump. The patient weighs 237lb. The IV is available at 25,000 units of Heparin in exactly 500 mL of IV fluid. Calculate the flow rate in mL/hr that should be set for the IV pump.

Answers

Answer 1

The flow rate of the IV pump should be 17.06mL/hr.

1st) We need to calculate the patient's weight knowing that 1 lb is equal to 0.45 kg:

[tex]\begin{gathered} 1\text{ lb-0.45 kg} \\ 237\text{ lb - x =}\frac{237\text{ lb}\cdot\text{0.45 kg}}{1\text{ lb}} \\ \\ x=106.65\operatorname{kg} \end{gathered}[/tex]

The patient weighs 106.65 kg.

2nd) If the patient needs a drip at 8.0 units per kg of body weight, we have to calculate the units for the patient:

[tex]\begin{gathered} 1\text{ kg - 8.0 units} \\ 106.65\text{ kg - x=}\frac{106.65\text{ kg}\cdot\text{8.0 units}}{1\text{ kg }} \\ \\ x=853.2\text{units} \end{gathered}[/tex]

So, the patient needs 853.2 units per hour.

3rd) To calculate the flow rate of the IV pump, we need to know the mL equivalent to 853.2 units:

[tex]\begin{gathered} 25,000\text{ units - 500mL} \\ 853.2\text{ units - x=}\frac{853.2\text{ units}\cdot\text{500mL}}{25,000\text{ units}} \\ \\ x=17.06mL \end{gathered}[/tex]

So, the flow rate of the IV pump should be 17.06mL/hr.

during the decomposition of 34 gr ammonia into nitrogen and hydrogen 92 KJ are absorbed. How many grams of ammonia are decomposed when 184 KJ are absorbed? write the decomposition reaction

Answers

Explanation:

Ammonia will decompose into nitrogen gas and hydrogen gas according to the following reaction. In that reaction 92 kJ will be absorbed.

2 NH₃ ----> N₂ + 3 H₂ ΔH = 92 kJ

Since the heat is absorbed, the sign is positive and we can add it to the reactants side.

2 NH₃ + 92 kJ ----> N₂ + 3 H₂

When 92 kJ are absorbed 34 g of ammonia are reacted. We can use that relationship to find the mass of ammonia that reacted when 184 kJ where absorbed.

34 g of NH₃ : 92 kJ

mass of NH₃ = 184 kJ * 34 g of NH₃/(92 kJ)

mass of NH₃ = 68 g

Answer: 68 g of ammonia were decomposed.

2 NH₃ ----> N₂ + 3 H₂ ΔH = 92 kJ

9. Calculate the molarity of a 400.0 mL solution that contains 41.5 g of NaCl.

Answers

Answer

1.775 M

Explanation

Given:

Volume of solution, V = 400.0 mL

Mass of NaCl = 45.5 g

What to find:

The molarity of the solution.

Step-by-step solution:

Step 1: Convert the volume from mL to L.

This can be done by dividing the volume in mL by 1000.

V = 400.0 mL = (400.0/1000) = 0.4L

Step 2: Convert the mass of NaCl to moles.

The mass can be converted to moles using the mole formula below:

[tex]\begin{gathered} Moles=\frac{Mass}{Molar\text{ }mass} \\ \end{gathered}[/tex]

From the periodic table, the molar mass is determined to be = 58.44 g/mol

Putting mass = 41.5 g and molar mass = 58.44 g/mol into the formula, we have:

[tex]Moles=\frac{41.5g}{58.44g\text{/}mol}=0.7101\text{ }mol[/tex]

Step 3: Calculate the molarity of the solution using the molarity formula.

Molarity formula is given by:

[tex]Molarity=\frac{Moles}{Volume\text{ }in\text{ }L}[/tex]

Moles= 0.7101 mol and V = 0.4 L

Therefore,

[tex]Molarity=\frac{0.7101mol}{0.4L}=1.775\text{ }M[/tex]

The molarity of a 400.0 mL solution that contains 41.5 g of NaCl = 1.775 M.

It can lower and expand the melting point if the sample is not dried completely.

Impurities may be present in a sample if the drying process is not complete. The melting point is decreased and widened when contaminants are still present in a sample. For instance, if a substance's usual melting point range is 104C to 106C, improper drying could result in the presence of impurities, which would lower and widen the melting point range to something like 85C to 97C.

Calculate the pOH for an aqueous solution containing 0.01 moles of HCl in a 2.5 L solution.

Answers

The question requires us to calculate the pOH value for a solution containing 0.01 moles of HCl in 2.5 L of solution.

To solve this problem, we'll need to go through the following steps:

I) calculate the molar concentration of the HCl solution to obtaine the concentration of H+ ions;

II) using the concentration of H+ ions, calculate the pH of the solution;

III) with the value obtained for pH, calculate the value of pOH for this solution.

Next, we'll go through the steps to solve the question:

I) Since the question provided the number of moles of HCl and the volume of the solution, we can calculate the molar concentration using the following equation:

[tex]\text{molar concentration = }\frac{\text{number of moles (mol)}}{\text{volume (L)}}_{}[/tex]

Thus, applying the values provided:

[tex]\text{molar concentration of HCl= }\frac{0.01\text{ mol}}{2.5\text{ L}}=0.004\text{ mol/L}[/tex]

Therefore, the concentration of the HCl solution is 0.004 mol/L.

Since HCl is a strong acid, we can expect it to completely dissociate in H+ and Cl-: the concentration of H+ ions for this solution would also be 0.004 mol/L ( [H+] = 0.004 mol/L).

III) The next step is calculate the pH of this solution. We'll use the following equation and apply the concentration of H+ ions obtained in the previous step ( [) using H+] = 0.004 mol/L):

[tex]pH=-\log _{10}\lbrack H^+\rbrack\to pH=-\log _{10}(0.004)=2.39[/tex]

Now, we know that the pH of the solution is 2.39.

III) The last step is use the pH value calculated (pH = 2.39) to calculate the pOH of the solution, using the following equation:

[tex]pH+\text{pOH =14}\to pOH\text{ = 14 - pH}[/tex][tex]\text{pOH = 14-2.39 = 11.6}[/tex]

Therefore, the pOH of the HCl solution given is 11.6.

We need to calculate the number of moles of aluminum needed to produce 30ml of H2 (hydrogen gas) at a temperature of 22°C and a pressure of 763mmHg.

To calculate the number of moles of hydrogen produced we use the ideal gas equation:

[tex]P.V=n.R.T[/tex]

Where:

P is the pressure

V is the volume

n is the number of moles

R is the gas constant

T is the temperature

R is a constant and it's value is:

[tex]R=8.314\text{ }\frac{m^3.Pa}{K.mol}[/tex]

So we need to convert each variable to the units of this constant.

[tex]\begin{gathered} T:\text{ }22^{\circ}C=295.15^{\circ}K \\ P:\text{ }763mmHg=101725\text{ }Pa \\ V:\text{ 30ml}:0.00003m^3 \end{gathered}[/tex]

Now we know that for every 2 moles of aluminum 3 moles of H2 are formed.

So we calculate the moles of Al needed:

[tex]n_{Al}=0.00124mol_{H2}.\frac{2mol_{Al}}{3mol_{H2}}=0.000826mol_{Al}[/tex]

So the answer is 0.000826 moles of Al°

How many grams of glucose are required to heat 175 mL of water from 20.0 °C to 25.0°C?

Answers

We must first determine the heat needed to heat 175mL of water. In the working temperature range we can assume that the density of water is 1g/mL, so the mass of water that we must heat will be 175g of water.

Now, the heat we need to heat that mass of water is calculated with the following equation:

[tex]Q=mCp\Delta T[/tex]

Where Q is the heat required to heat the water

Cp is the specific heat of water equal to 4186 J/g°C

delta T is the change of temperature = 25°C-20°C=5°C

We replace the know values:

[tex]Q=175g\times4186\frac{J}{g\degree C}\times\frac{1kJ}{1000J}\times5\degree C=3662.75kJ[/tex]

Now, to heat the water they tell us that the glucose combustion will take place. We must assume that all the heat generated in the reaction will go to heating the water and that there is no heat loss to the environment.

The combustion reaction of glucose generates 2538.7 kJ/mol. So the moles of glucose needed will be:

[tex]\begin{gathered} molGlucose=givenHeatrequired\times\frac{1molGlucose}{2538.7kJ} \\ molGlucose=3662.75kJ\times\frac{1molGlucose}{2,538.7kJ}=1.44molGlucose \end{gathered}[/tex]

Considering the ideal gas law, the pressure in a 7.00 L tank with 1.73 grams of hydrogen gas at 375 K is 26.5987 atm.

Definition of ideal gas law

An ideal gas is called a hypothetical or theoretical gas, which would be composed of particles that move randomly and without interacting with each other.

An ideal gas is characterized by three state variables: absolute pressure (P), volume (V), and absolute temperature (T). The relationship between them constitutes the ideal gas law, an equation that relates the three variables if the amount of substance, number of moles n, remains constant and where R is the molar gas constant:

P×V = n×R×T

Pressure in this case

In this case, you know:

P= ?V= 7 Lmass of hydrogen= 1.73 gmolar mass of hydrogen= 1 g/molen= mass of hydrogen× molar mass of hydrogen= 1.73 g÷ 1 g/mole= 1.73 molesR= 0.082 atmL/molKT= 375 K

Replacing in the definition of ideal gas law:

P× 2 L = 1.73 moles ×0.082 atmL/molK ×375 K

Solving:

P= (1.73 moles ×0.082 atmL/molK ×375 K)÷ 2 L

P= 26.5987 atm

Neon has the electronic configuration of 2, 8, This implies that it belongs to period 2 and group 8

Recall, that Neon is a noble gas. Noble gases do not accept or release electrons.

Hence, neon does not have the tendency to accept or release electrons.

Neon as a noble gas has a large positive value for electron affinity

Therefore, the statement is not TRUE

Which types of electron orbitals will have higher energy than a 4d orbital?A. 4pB. 3sC. 4fD. 5s

Answers

Answer:

5s. Option D is correct

Explanations:What are electron orbitals?

Electron orbitals are area around the nucleus where electron resides. The closer the orbital to the nucleus, the higher the energy level.

Based on the explanation above, 5s will be higher in energy than the 4d orbital.
