Consider the hypothetical reaction A + 2B → 3C + 4D Over an interval of 2.50 s the average rate of change of the concentration of C was measured to be 0.0620 M/s. What is the final concentration of B at the end of this same interval if its concentration was initially 1.700 M?

Given the following reaction: c3h8+5o2=3co2+4h20 how many grams of co2 will be produced 7 g of c3h8 and 98 g of o2

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.
