Answer:
Explanation:
When looking at a chemical reaction, the substance present before the reaction takes place are called the (5)
REACTANT
and the substance produced after the reaction are the (6).
PRODUCT
know through the Law of Conservation of (7)
MATTER
that nothing is created or destroyed. This is reflected in a (8
BALANCED
chemical equation, where the NUMBER OF atoms of each element on each side of the arrow is (9)-
equal
or the same.
REMEMBER: WHEN BALANCING EQUATIONS YOU CANNOT CHANGE THE SUBSCRIPTS OF THE COMPOUNDS, YOU CAN ONLY SHOW BY THE COEFFICIENTS HOW MANY MOLECULES YOU HAVE!
<span>The combined gas equation relates three variables pressure, temperature and volume when the number of moles is constant.
The equation is PV / T = constant. Which is valid for a fixed number of moles of the gas.
You can derive the combined gas equation from the combination of Bolye's law, Charles' law and Gay-Lussac's law, which needs some algebra.
Answer: option 2. number of moles.

Answer:
2.74 × 10⁸ M⁻¹.s⁻¹ = 2.74 × 10⁸ L.mol⁻¹.s⁻¹
Explanation:
Let's consider the following second-order reaction.
NO(g) + F₂(g) → NOF(g) + F(g)
We can find the rate constant (k) using the Arrhenius equation.
where,
- T: absolute temperature (695°C + 273.15 = 968 K)
