Answer: [tex]2Fe^{3+}(aq)+3Mg(s)\rightarrow 3Mg^{2+}(aq)+2Fe(s)[/tex]
Explanation:
Complete ionic equation : In complete ionic equation, all the substance that are strong electrolyte and are present in an aqueous state and represented in the form of ions.
Net ionic equation : In the net ionic equations, we do not not include the spectator ions in the equations.
Spectator ions : The ions present on reactant and product side which do not participate in a reactions. The same ions present on both the sides.
The complete balanced ionic equation will be:
[tex]2Fe^{3+}(aq)+6Cl^-(aq)+3Mg(s)\rightarrow 3Mg^{2+}(aq)+6Cl^-(aq)+2Fe(s)[/tex]
In this equation, [tex]Cl^-[/tex] are the spectator ions.
By removing the spectator ions from the balanced ionic equation, we get the net ionic equation.
The net ionic equation will be:
[tex]2Fe^{3+}(aq)+3Mg(s)\rightarrow 3Mg^{2+}(aq)+2Fe(s)[/tex]

OPEN ENDED QUESTION A chemistry student has a 5.001 g of CaCl2. How many moles of CaCl2 does the student have? (mm CaCl2 = 110.98 g)
Answer:
0.04506 mol
Explanation:
For this problem, you need to convert grams to moles. To do this, you need the molar mass, which is given. Divide the mass by the molar mass to find the moles you have.
(5.001 g)/(110.98 g/mol) = 0.04506 mol
Calculate the number of moles in 3.440 x 10^35 formula units of RbF. (Molar mass of RbF is 104.47g/mol).

How many grams of hydrogen reacts with 32 g of oxygen to produce 34 g of hydrogen peroxide
Answer:
2 grams.
Explanation:
H2 + O2 ---> H2O2
Using molar masses:
2*1 g hydrogen reacts with 2*16 g oxygen.
so 2g H2 reacts with 32 g O2.

to raise its temperature 225?
Answer:
One of water's most significant properties is that it takes a lot of heat to it to make it get hot. Precisely, water has to absorb 4,184 Joules of heat (1 calorie) for the temperature of one kilogram of water to increase 1°C.

Fe2O3 (s) + 2 Al (s) ---> 3 Fe (l) + Al2O3 (s) Based on the thermite reaction, how much aluminum oxide (Al2O3) is formed from 8.0 grams of aluminum (Al)?
Answer:
15.3 g
Explanation:
Fe₂O₃ (s) + 2Al (s) → 3Fe (l) + Al₂O₃ (s)First we convert 8.0 grams of aluminum into moles, using its molar mass:
8.0 g Al ÷ 27 g/mol = 0.30 mol AlThen we convert 0.30 moles of aluminum into moles of aluminum oxide, using the stoichiometric coefficients:
0.30 mol Al * [tex]\frac{1molAl_2O_3}{2molAl}[/tex] = 0.15 mol Al₂O₃Finally we convert 0.15 moles of Al₂O₃ into grams, using its molar mass:
0.15 mol Al₂O₃ * 102 g/mol = 15.3 g Al₂O₃A doctor tapes a patients knees with a hammer to test the reflex which can provide information about the condition of the _____

Un elemento químico está compuesto por átomos específicos, por ejemplo el oxígeno, el helio, el sodio, cloro. Por otro lado, un compuesto químico es la combinación de dos o más elementos químicos diferentes, por ejemplo, cloruro de sodio, que forma por la combinación de sodio y cloro (NaCl), dióxido de carbono, que se forma por la unión de carbono con tres átomos de oxígeno (CO₃), agua que se forma por la combinación de dos átomos de hidrógeno con un átomo de oxígeno(H₂O), etc.
The process of water changing from a liquid to solid is called?
Answer:
freezing
Explanation:
When a solid reaches the temperature of its melting point, it can become a liquid. For water, the temperature needs to be a little over zero degrees Celsius (0oC) for you to melt. ... The reverse of the melting process is called freezing. Liquid water freezes and becomes solid ice when the molecules lose energy.

Why do some animals defend their territory after they have mated
and reproduced?
a.They can gain more food for their offspring
b.they can provide a larger nest for their offspring.
c.They are naturally aggressive.
d.They are carrying out a mating dance.
Answer:
i believe it is a
Explanation:
The reason is :a.They can gain more food for their offspring
Animals tend to protect their territory because they don't want intruders to invade their territory.
Animals majorly protect their territory in order to protect their foods from been eating by intruders as this will enables their offerings to have enough foods to eat.
They as well guard their territory in order to prevent intruders from invading the place they have prepare as their mating place.
Inconclusion The reason why some animals defend their territory after they have mated
and reproduced is :a.They can gain more food for their offspring

A. butylcyclohexane
B. butylcyclopentane
C. propylcyclohexane
Answer:
The answer for this question is A. butylcyclohexane
Explanation:
Choose letter A
You welcome have a nice day.
Name of the given compound is butyl cyclohexane.
What are cyclo alkanes?Cyclo alkanes are those organic compounds in which alkanes are present in the cyclic form.
In the nomenclature of cyclo alkane, name of the substitute is put before the name of the main ring. In the given structure number of carbons in ring is 6 so that given cycloalkane is cyclohexane and butyl group is attached as substitute. So name of the given compound is butyl cyclohexane.
Butyl cyclopentane is wrong because 6 carbons are present in ring.Propylcyclohexane is also wrong because 4 carbons are attached in the ring.Hence name of the compound is butyl cyclohexane.

Question 16
A hockey puck is hit with a large force. The puck moves at a high speed as it slides over the ice.
What happens according to Newton’s first law of motion?
A) The puck does not lose any speed because ice is a very slippery surface.
B) The puck gradually slows down because mass makes objects slow down.
C) The puck gradually slows down because friction would be acting on it.
D) The puck does not lose any speed because once an object starts moving, the force of friction would no longer apply to it.
Answer:
C) The puck gradually slows down because friction would be acting on it.
Explanation:
It would be C because the puck would be scraping the ice and when it's scraping it slowly losses its speed because the ground is pushing it lightly
