At STP what is the density of a gas that has a gram molecular mass of 32 grams?
Answer:1.4 g/L
Explanation:
One mole of very substance at STP contains a volume of 22.4 liters. Density can be found by dividing the mass by volume . The density of the gas with a molecular mass of 32 grams is 1.42 g/l.
What is density?Density of a substance is the measure of its mass per volume. It represents how much denser it is in a given volume. Density depends on the molecular weight, bond type, volume, temperature and pressure.
STP is defined as the condition of standard temperature and pressure. 293 K and 1 atm pressure are considered to be the standard conditions. At STP, the volume of one mole of every substances contains 22.41 liters.
It is given that the molecular weight of the gas is 32 g/mol. Thus its density in one mole can be calculate as follows:
Density = mass/ volume.
= 32 g/ 22.4 L
= 1.42 g/L.
Hence, the density of the gas at STP with molecular mass of 32 g is 1.42 g/L.

When 72 grams of aluminum react, the actual yield is 125.5 grams, what is the percent yield?
i got a few mins left
Answer:
32.3%
Explanation:
Percent yield is defined as:
Actual yield (125.5g) / Theoretical Yield * 100
To find theoretical yield we have to find the moles of aluminium. As 2 moles of Al produce 2 moles of AlCl3, the moles of Al = Moles AlCl3.
With these moles we can find the mass assuming a 100% of yield (Theoretical Yield) as follows:
Moles Al = Moles AlCl3 (Molar mass Al = 26.98g/mol)
72g Al * (1mol / 26.98g) = 2.67 moles AlCl3
Mass AlCl3 (Molar mass: 133.34g/mol)
2.67 moles AlCl3 * (133.34g / mol) = 355.8g AlCl3
Percent Yield = 125.5g / 355.8g * 100 =
32.3%What is the frequency of an X-ray that has a wavelength of 1.5 x 10 -9 m? The speed of electromagnetic radiation is 3.0 x 10 8 m/s. [v = λƒ]
Answer:
2.0x10¹⁷ Hz is the frequency of the X-ray
Explanation:
We can find the frequency of a wave of energy from the wavelenght and its speed using the formula:
v = λƒ
Where v is speed (For electromagnetic radiation = 3.0x10⁸m/s)
λ is the wavelength in meters = 1.5x10⁻⁹m
And f is the frequency in s⁻¹ = Hz
Replacing:
3.0x10⁸m/s = 1.5x10⁻⁹m*ƒ
3.0x10⁸m/s / 1.5x10⁻⁹m = f
f =
2.0x10¹⁷ Hz is the frequency of the X-ray

How does the atmospheric pressure at altitudes above sea level compare with atmospheric pressure at sea level?
A. The atmospheric pressure above sea level is higher.
B. The atmospheric pressure at sea level is higher.
c. The pressures are the same.
D. Differences in pressures cannot be determined.
Answer:
Option B
The atmospheric pressure at sea level is higher.
Explanation:
Atmospheric pressure can simply be understood as the weight of the air molecules in the atmosphere. The higher we go up into the atmosphere, the thinner the air becomes. This means that the air present at higher heights is not so much, and hence, the air is lighter. This is why most fighter jets and mountain climbers need oxygen tanks to breathe properly.
Due to the fact that the air is less dense (lighter) at higher altitudes, it also means that the atmospheric pressure at higher altitudes is less.
Therefore, the atmospheric pressure at the sea level is higher than the atmospheric pressure at altitudes above sea level
Answer:
B. The atmospheric pressure at sea level is higher.

Which term is used to describe the maximum amount of a product that can be produced by a given amount of reactant? (5 points) a Catalytic reactant b Excess reactant c Limiting reactant d Theoretical yield
Answer:
d Theoretical yield
Explanation:
I took the test :)
Theoretical yield term is used to describe the maximum amount of a product that can be produced by a given amount of reactant
What is Theoretical yield?The theoretical yield is just the maximum mass of a product that a chemical reaction can produce.
Theoretical yield the amount of product produced by a perfect (theoretical) chemical reaction, not the amount that will receive from a laboratory reaction. The balanced chemical equation can be used to calculate theoretical yield, the limiting reactant's mass and relative formula mass, as well as the product's relative formula mass.

the actual parameter value of a population?
O A. 15

C. 85
D. 50
the closest value is C, 85.
hope it helps!!!!
85 is the estimate value that is obtained from a sample of which size is likely to be closest to the actual parameter value of a population. Therefore, the correct option is option C.
What is population?A population is the entire set of people in a group, whether that group is a country or a collection of people who share a certain trait. A population is the group of people where a statistical sample has been collected in statistics. Hence, a population is any collection of people who have something in common.
A statistically substantial chunk of a population, rather than the full population, may also be referred to as a sample. For this reason, the standard deviation, meaning standard error, of a statistical study of a sample from the full population must be disclosed. Only a population-wide analysis would have zero standard deviation. 85 is the estimate value that is obtained from a sample of which size is likely to be closest to the actual parameter value of a population.
Therefore, the correct option is option C.

How does genetic variation make a community more stable? Include explanations of how genetic variation is related to the struggle to survive, differential reproductive success, heredity, natural selection, and evolution
Answer:
If you have genetic variation then a community is more likely to survive because the population is more likely to have individuals who are fine if there are environmental changes. Then natural selection will happen and the species will evolve to he adapted to the new environment. If everyone in a population has the same genetics, than one thing could take them all out.

A 45.2 g sample of Silver at 101.0 ºC is dropped into 300.0 g of water at 30.6 ºC. What is the final temperature of the water?
Answer:
Final temperature of water = 31.2° C
Explanation:
Let the final temperature of water be T degrees
Concept: By energy conservation law
Heat lost by the silver = heat gained by water
Heat lost be silver Q1 = m1c1ΔT1
Q1 = 45.2/1000Kg×2.36J/KgK×(101-T)
Heat gained by water Q2 = m2c2ΔT2
Q2 = 300/1000Kg×4.186J/KgK(T-30.6)
Since, Q1=Q2
⇒ 45.2/1000Kg×2.36J/KgK×(101-T) = 300/1000Kg×4.186J/KgK(T-30.6)
Solving we get T = 31.2° C
Therefore, final temperature of water = 31.2° C
what is tyndall effect
The scattering of the particles of the light in suspension and colloid is the Tyndall effect or scattering.
What are colloidal solutions?Colloidal and suspension are the types of solution that contains the mixture of the solute in the solvent. The colloidal solution includes the insoluble solute dispersed in the medium.
The light directed towards the colloidal solution gets scattered by the solute particles present in the solution and hence is used to prove true solutions apart from the colloidal and suspension.
Therefore, the Tyndall effect is the light scattering by colloidal solution.
