I am supposed to show all my work. but I forgot how to do everything other than balance it. 2.1g H2 reacts with 3.5g CO2 in a synthesis reaction in a 3.5 L solution

Write the balanced equation
Determine the limiting reagent (LR)
What is the molarity of the solution (based on the LR)?
[H3O+] = ?
[OH-] = ?

How many moles of sulfur dioxide are produced when 4.38 moles of oxygen completely react with iron (iv) sulfide

Which statements are true concerning mineral formation? check all that apply. the slower the cooling, the larger the crystals. the faster the cooling, the smaller the crystals. crystals formed from magma are smaller than crystals formed from lava. minerals can only form in solutions when the solution is heated deep underground. when a solution cools, elements and compounds leave the solution and crystallize as minerals. minerals formed from hot water solutions can form narrow channels in the surrounding rock.

Water undergoes a large change in density at 0 ∘ c as it freezes to form ice. calculate the percent change in density that occurs when liquid water freezes to ice at 0 ∘ c given that
