Stoich questions...

1) convert the grams of Au to moles
(33.5g)/(196.7g/mol)=___x___

2)find how many atoms are in that many moles by multiplying it by avogadro's number.

x(moles of Au)*(6.02*10^23)=?

3)now that you have found the number of atoms of gold, convert it to grams of aluminum by multiplying it by Avogadro's number and multiplying it by the atomic mass of aluminum.
( ? )(6.02*10^23)(26.98g/mol)= (mass of Al)

If you heat the cup of soup in the microwave to make it boil. Will it have a higher total kinetic energy than the bowl of soup?
Paha777 [63]

No, The kinetic energy depends upon the number of particles motion. The hot bowl of soup will have greater number of particles in motion and it will contain more kinetic energy than the cup of soup.

#1
The correct answer is A.)

Because the animal has sperm that means that the offspring will be different. This is because at conception, the two parents sex cells combine their DNA to make a new creature.

#2
The correct answer is B.)

Genetic variation produces different offspring, and some are more adapted to others. The ones that survive pass on their genes. This is know as "Survival of the Fittest". Asexually organisms are exactly like their parents, so if they have any type of genetic defaults, then their offspring will get them too. 

Hope this helps!

1. Which of the following is a correctly written thermochemical equation?
WITCHER [35]

Explanation:

1. Thermochemical equation is balance stoichiometric chemical equation written with the phases of the reactants and products in the brackets along with the enthalpy change of the reaction.

The given correct thermochemical reactions are:

Fe(s)+O_2(g)\rightarrow Fe_2O_3(s),\Delta H = 3,926 kJ&#10;

C_3H_8(g)+5O_2 (g)\rightarrow 3CO_2 (g)+4H_2O(l),\Delta H= 2,220 kJ/mol

2. Phase change affect the value of the enthalpy change of the thermochemical equation. This is because change in phase is accompanied by change in energy. For example:

H_2O(s)\rightarrow H_2O(g),\Delta H_{s}=51.1 kJ/mol

H_2O(l)\rightarrow H_2O(g),\Delta H_{v}=40.65 kJ/mol

In both reaction phase of water is changing with change in energy of enthalpy of reaction.
