The balanced chemical equation is Pb(NO3)2+ 2KI produces PbI2 + 2K(NO)3
.4 L of KI × (.375 mol/L of KI) × (1 mol of PbI2 / 2 mol of KI) × (461 g of PbI2/1 mol of PbI2)
=34. 6 g of PbI2 precipitate.
According to Gay-lussac’s law, if the temperature of a gas increases, then the the pressure ALSO INCREASES.
Answer:
0.014 M/s
Explanation:
The rate of a chemical reaction is defined as the change in the concentration of the products or reactants over a specific period of time. The reaction rate can be calculated by dividing the change in concentration of the reactants products by the time elapsed for the given reaction. The reaction rate can also be calculated bu using:
![r = k*[CH_{3}Br]*[NaOH]](https://tex.z-dn.net/?f=r%20%3D%20k%2A%5BCH_%7B3%7DBr%5D%2A%5BNaOH%5D)
where:
r is the rate of the reaction, k is the rate constant, and [] signifies the concentration of the compound.
When the concentrations of 
and NaOH are both 0.140 M, the rate of the reaction is 0.0070 M/s.
Therefore, when the concentration of is doubled, the rate of the reaction will also be doubled, i.e. r = 2* 0.0070 = 0.014 M/s
Neither N₂ or O₂ are greenhouses gases because they do not cause the greenhouse effect.
<h3>What are greenhouses gases?</h3>
Greenhouse gases trap heat in the atmosphere causing the temperature of the planet to rise.
Greenhouse gases cause the greenhouse effect.
<h3>What is the greenhouse effect?</h3>
The greenhouse effect is the warming up of the planet due to greenhouse gases.
Greenhouse gases include
- carbondioxide
- methane
- nitrous oxide and
- water vapour
So, neither N₂ or O₂ are greenhouses gases because they do not cause the greenhouse effect.
