N2 + 3 H2 --> 2 NH3
The balanced equation above indicates that if 2 moles of N2 react, then
2 moles of H2 will also react
3 moles of H2 will also react
4 moles of NH3 will be produced
2 moles of NH3 will be produced
Answers
Answer:
4 moles of NH3 will be produced
Explanation:
The reaction expression is given as:
N₂ + 3H₂ → 2NH₃
We have to check that the equation of the reaction is balanced.
Then;
if 2 mole of N₂ reacts;
1 mole of N₂ will react with 3 mole of H₂ to produce 2 mole of NH₃
2 mole of N₂ will react with (2x3)mole of H₂ to produce (2x2)mole of NH₃
6mole of H₂ to produce 4 mole of NH₃
Answer:
According to the balanced chemical equation N2 + 3 H2 --> 2 NH3, for every 1 mole of N2 that reacts, 3 moles of H2 are required to react completely to form 2 moles of NH3. Therefore, if 2 moles of N2 react, then 6 moles of H2 will also react to form 4 moles of NH3.
So the correct answer is: 6 moles of H2 will also react, and 4 moles of NH3 will be produced.

Which statements describe or apply the principal of conservation of energy? Select all that apply.
* A. Energy cannot be created or destroyed; it can only be transferred from one location to
another.
B. Home insulation can reduce energy bills by conserving energy that would otherwise be lost.
* C. If the temperature in one location decreases, then the temperature in another location
increases.
D. The total energy in a closed system such as Earth stays the same.
E. Nonrenewable energy resources can be conserved, but they will eventually run out.
Answers
Answer:
A, C, and D
Explanation:
The correct options that apply to the principal conservation of energy are A, C, and D.
A is correct because energy can neither be created nor destroyed. However, energy can be transfered from one location to another or be converted from one form to another. Whether transferred to converted, the magnitude remains the same.
C is correct because energy cannot be destroyed but can be transferred or converted. Hence, if a body or a location loses temprature, then the loss is being gained by another body or location.
D is also correct. A closed system is a system that does not exchange matter with its surroundings. Hence, the total energy remains the same within the system.
Answer:
The total energy in a closed system such as Earth stays the same.
Explanation:
The simplest statement of the law of conservation of energy is that energy can neither be created nor destroyed but can be converted from one form to another.
A typical illustration of this principle of conservation of energy is a closed system of which our universe is an important example.
The total amount of energy in the universe is always a constant. Energy lost in one part must be equal to the energy gained on the other part.

Answers
Answer:
Combination or synthesis reaction
Explanation:
The reaction is a combination or synthesis reaction.
Let us write the reaction equation:
CO + H₂O → H₂CO₃
A combination or synthesis reaction is one in which a single product forms from two or more reactants. The formation of a compounds from the union of their constituent elements falls into this category of reaction.

Chemists want to place 2 x 10^24 atoms of carbon in a chemical reaction. How would they obtain this amount?
Answers
Answer:
Explanation:
To determine what is been asked in this question, firstly, the formula to determine the number of atoms present in a substance must be used. The formula is
number of atoms = n × 6.02 × 10²³
where n is the number of moles
6.02 × 10²³ is avogadro's number
The number of atoms needed (to be present) has already been provided in the question as 2 × 10²⁴
Thus;
2 × 10²⁴ = n × 6.02 × 10²³
n = 2 × 10²⁴ ÷ 6.02 × 10²³
n = 3.32
The number of moles of carbon that will be placed in the reaction will be 3.32 but to determine the amount/mass of carbon that will be used in the reaction, we will use the formula
n = mass/molar mass
The molar mass of carbon is 12 g/mol
Thus;
3.32 = mass/12
mass = 3.32 × 12
mass = 39.84 g
The mass of carbon that will be required for the reaction will be 39.84, the procedure above shows how to obtain this amount.

Which explains the law of conservation of mass?
a. Every reaction creates an equal amount of mass related to the amount of
energy required for the reaction.
b. The total mass before a chemical reaction is the same as the total mass after
the reaction.
c. Matter can not be conserved.
d. The total amount of mass is equal to the volume of both chemicals in the
reaction.
Answers
Answer:
A is your answer.
Explanation:
This law states that, despite chemical reactions or physical transformations, mass is conserved — that is, it cannot be created or destroyed — within an isolated system. In other words, in a chemical reaction, the mass of the products will always be equal to the mass of the reactants.
Which substance is most likely metallic
Answers
You can put the picture there so we can see.
The substance which is most likely metallic is that with least number of valence electrons according to electronic configuration.
What is electronic configuration?
Electronic configuration is defined as the distribution of electrons which are present in an atom or molecule in atomic or molecular orbitals.It describes how each electron moves independently in an orbital.
Knowledge of electronic configuration is necessary for understanding the structure of periodic table.It helps in understanding the chemical properties of elements.
Elements undergo chemical reactions in order to achieve stability. Main group elements obey the octet rule in their electronic configuration while the transition elements follow the 18 electron rule. Noble elements have valence shell complete in ground state and hence are said to be stable.
