Answer:
1) first order
2) zero order
3) second order
Explanation:
For a first order reaction, the concentration of the reactants varies exponentially with the rate of reaction. The curve of a first order reaction shows an exponential relationship between the rate of reaction and the change in the concentration of reactants.
For a zero order reaction, the rate of reaction is independent of the concentration of the reactants. So, regardless of the amount of reactant in solution, the rate of reaction is constant.
For a second reaction, the reaction rate increases in direct proportion to the concentration of the reactant in solution.
Limestone is calcium carbonate Ca(Co3) it's dissociation equation is as follows:
Ca(CO3) <----> Ca+2 + CO3-2
but the solubility is very small
in the presence of acid by LeChatlier's Principle you can shift to the right by adding acid
H+ + CO3-2 <-----> H+CO3- (the bicarbonate ion which is really soluble)
The system will pull more and more limestone out into solution as acid is added and neutralize the acid coming from the rain.
Answer:
Two slender woolen sweaters are hotter than a thick woolen sweater in light of the fact that there is a layer of air between them that doesn't permit our body warmth to get away yet it likewise it doesn't retains heat from the climate and fleece is additionally a protector that itself doesn't permit our body warmth to get away
7 × 10² pounds of Cl₂ would be produced in a typical 8-h operating day.
<h3>What is Stoichiometry ?</h3>
Stoichiometry helps us use the balanced chemical equation to measures quantitative relationships and it is to calculate the amount of products and reactants that are given in a reaction.
<h3>What is Balanced chemical equation ?</h3>
The balanced chemical equation is the equation in which the number of atoms on the reactants side is equal to the number of atoms on the product side in an equation.
2Cl⁻ (aq) → Cl (g) + 2e⁻
According to stoichiometry, moles of Cl₂
= 4477 moles
Pounds Cl₂
= 7 × 10² lb
Thus from the above conclusion we can say that 7 × 10² pounds of Cl₂ would be produced in a typical 8-h operating day.
