Answer:

When factories mass produce something it produces smoke. That smoke can be harmful to something called the ozone layer. The ozone layer is part of earth's atmosphere that protects us from the suns burning heat. When that layer is damaged the sun's heat burns through heating up the world and melting ice causing the water levels to rise. All of this can make working conditions less safe, cause more flooding, and have the sun cause cancer.

mariarad [96]

A. PV=constant
752 torr = 0.989 atm
(0.989 atm)(4.38 L) = (1.88 atm)V
V = 2.30 L

B. T/V = constant
(294 K)/(4.38 L) = (448 K)/V
V = 6.67 L

G the hydrogen generated in this lab was a product of the reaction between magnesium and hydrochloric acid. which of these react

Colt1911 [192]

The limiting reactant is determined by the supply and stoichiometric equation.

<h3>Limiting reactants</h3>

They are reactants that are limited in availability, and thus, determine how far reactions can go in terms of producing products.

In a reaction involving magnesium and hydrochloric acid to produce hydrogen gas as follows:

$Mg + 2HCl --- > MgCl_2 + H_2$

The number of moles of HCl is twice that of Mg. Thus, if both reactants are supplied in the required proportion, no reactant will be limiting.

However, if the number of moles of HCl supplied is not up to twice that of Mg, HCl will become limiting. Also, if the amount of Mg supplied is not equal to half of that of HCl supplied, Mg will be limiting.
