harkovskaia [24]3 years ago
3 0

Answer:

1.41 *10^{3}  kJ/mol

Explanation:

First, we find in the tables the ΔH of formation of each compound. As you can see in the (image 1)

Then we solve the ecuation for ΔH°reaction

ΔH°reaction=∑ΔH°f(products)−∑ΔH°f(Reactants)

ΔH°reaction= (-2* 393.5 - 2*285.8) - (52.4 + 0) kJ/mol

ΔH°reaction = -1.41 *10^3  kJ/mol

An element and an atom are different but related because
White raven [17]

Answer:

c) An element is made up of all the same type of atom

Explanation:

Atoms are the smallest unit of an element that consists of protons, electrons and neutrons in its structure. An element is the smallest part of a chemical substance that cannot be disintegrated i.e. it cannot be broken down further.

Atoms and elements are different in many ways but they are connected in the sense that an element contains only one type of atoms. For example, aluminum element is made up of only aluminum atoms. Different atoms form a molecule but same atoms form an element.

Explanation:they then find a female angler fish, attach by bitting into her flesh and fusing to her body. So whatever she eats they eat too.

A nitrox ii gas mixture for scuba diving contains oxygen gas at 53 atm and nitrogen gas at 94 atm . what is the total pressure,
Alina [70]

Answer: The total pressure will be 1,11,720 torr.

Explanation:

Partial pressure of nitrogen gas.p_{N_2}=53 atm=53\times 760 torr= 40,280 torr (1atm = 760 torr)

Partial pressure of oxygen gas,p_{O_2}=94 atm=94\times 760 torr=71,440 torr

Total pressure, in torrs, of the scuba gas mixture = 40280 + 71440 torr =111,720 torr

Hence , the total pressure in scuba gas mixture is 111,720 torr.
