In an explosive chemical reaction, potassium metal reacts with water to form potassium hydroxide, KOH, and hydrogen gas. Suppose you have 1.73 g of potassium and 3.00 g of water. Which reactant will produce less potassium hydroxide (limit the reaction)? Hint: convert both g of K and g of H2O to moles of KOH. 2K + 2H2O –––> 2KOH + 1H2

· a) 10.0 g b) 11.6 g c) 6.94 g d) 8.72 g e) 5.02 g What is the percent yield for a process in which 10.4 g CH3OH reacts and 10.1 g CO₂ forms according to the following equation? inoltation 2CH₂OH()+30₂(g) a) 97.1% b) 70.7% c) 52.1% 2CO2(g) + 4H₂O(1) d) 103% e) 37.9% How any moles of NH, can be produced by the

How would you balance this equation N2H4(I) -----> NH3(g) + N2(g)

You can click on the Review link to access the section in your Text Consider the following reaction: 2CH3OH(g) +30 (g) → 200; (g) + 4H₂O(g) Each of the following molecular diagrams represents an initial mixture of the reactants How many CO₂ molecules would be formed from the reaction mixture that produces the greatest amount of products? Express the number of molecules as an integer. ▸ View Available Hint(s) N-2 ΜΕ ΑΣΦ molecules Submit Each molecule represents a mole of available reactant. To simplify calculations and reporting, the units used in the problem will be molecule X Incorrect: Try Again; 3 attempts remaining First, identify the limiting reactant, which is the substance that is completely consumed during the reaction. You can then determine how much product is produced using the ratio of the limiting reactant to the desired product You may want to review Hint 1. How to approach the problem.

Chemistry How many carbon dioxide molecules are there in 14.4 gigatonnes of CO2? How many carbon dioxide is generated by burning 2.2 gigatonnes of coal? The molar mass of CO2 is 44.01 g/mole

Consider the reaction below. Calculate how much H2O (l), in grams, can be produced if 2.5 moles of H2 is allowed excess O2? 2 H2 (g) + O2 (g) à 2 H2O (l)

What type of reaction is SO2(g) + O2(g) —-> SO3? Is it balanced?
