<span>60. 4Li(s) + O2(g) >>>>>>>>>>> 2Li2O(s)
moles O2 required = (84 grams Li) * (1 mol Li / 6.941 grams Li) * (1 mol O2 / 4 mol Li) = 3.026 moles O2 required.
PV = nRT, P = 1 atm, V = ?, n = 3.026 moles, R = 0.0821 L*atm/mol*K, T = 273 K
(1 atm)*(V) = (3.026 moles O2) * (0.0821 L*atm/mol*K) * (273 K)
V = 67.82 Liters is the answer.

A collision hypothesis that claims a chemical reaction can only happen when reactants collide at the right angle and with enough kinetic energy.
<h3>What in chemistry is a reactant?</h3>
A material that's also present at the outset of such a chemical reaction is known as a reactant. Products are the substrate(s) to the side of the arrow. A component that remains after a chemical reaction is finished is known as a product.
<h3>Which side are the products and reactants?</h3>
The chemicals (what you started with) be transformed into byproducts in a chemical process (what you end with). An arrow separates the reaction mixture, which are indicated on the left side of a solution, from the products, who are depicted on the right.

Answer:
Sun
Explanation:
The closest star from the Earth is the sun.
18 miles because 6 mph*3 hours=18 miles

In Step 5, you will calculate H+/OH– ratios for more extreme pH solutions. Find the concentration of H+ ions to OH– ions listed in Table B of your Student Guide for a solution at a pH = 2. Then divide the H+ concentration by the OH– concentration. Record these concentrations and ratio in Table C.
What is the concentration of H+ ions at a pH = 2?
<h3>
0.01 mol/L </h3>
What is the concentration of OH– ions at a pH = 2?
<h3>
0.000000000001 mol/L
</h3>
What is the ratio of H+ ions to OH– ions at a pH = 2?
<h3>
