In a spacecraft, the carbon dioxide exhaled by astronauts can be removed by its reaction with lithium hydroxide. CO2 + 2 LiOH = Li2CO3 + H2O If 20 moles of CO2 is exhaled, the average amount exhaleed by a person each day, how much (in grams) Li2CO3 is produced?

What is the mass in grams of NO that will be produced from 22.9 g of NO, reacted with excess water in the following chemical reaction? 3 NO2(g) + H,0(1) → 2 HNO3(g) + NO(g) 2 ΗΝΟ:

Consider the following reaction: If 10.0 g of KF are used, how many grams of CaF2 can be formed? Ca(NO3)2 (aq) + 2 KE (aq) → CaF₂ (s) + 2 KNO3(aq)

Which of the following is not a combination reaction?     2 Na (s) + I2 (g) → 2 NaI (aq)     CaO (s) + CO2 (g) → CaCO3 (s)     CH4 (g) + 2 O2 (g) → CO2 (g) + 2 H2O (l)     N2 (g) + 3 H2 (g) → 2 NH3 (aq)     PbCO3 (s) → PbO (s) + CO2 (g)

For the given chemical equation, write the necessary stoichiometric coefficients to balance the equation. Note that normally we wouldn't write a coefficient of one, however you must include a coefficient of one if appropriate to not lose points. Al(s) + H2SO4(aq) → Al2(SO4)3(aq) + H2(g)

When HCl(g) and NH3(g) are mixed, a white solid forms. What is the balanced equation for this reaction? The answer is HCl(g) + NH3(g) = NH4Cl(s)   Can you please do a step by step to teach me?

Calculate the theoretical yield of the product in moles for each of the initial quantities of reactants. Ti(s) + 2Cl2(g) -> TiCl4(s)

Hydrogen gas reduces carbon dioxide gas to form methane (CH4) gas and steam. Choose the correct balanced net ionic equation (simplest whole-number coefficients) for this reaction.

Using the balanced equation: FeCl3(aq) + 3 NaOH (aq) ------> FeOH3 (s) + 3 NaCl (aq), determine the mass of solid product that can be made by starting with 14.0 grams of iron (III) chloride and 9.0 grams of sodium hydroxide.

Manganese commonly occurs in nature as a mineral. The extraction of manganese from the carbonite mineral rhodochrosite, involves a two-step process. In the first step, manganese (II) carbonate and oxygen react to form manganese (IV) oxide and carbon dioxide: 2 MnCO3(s) + O₂(g) 2 MnO₂ (s) +2 CO₂(g) In the second step, manganese (IV) oxide and aluminum react to form manganese and aluminum oxide: 3 MnO₂(s) +4 Al(s)-3 Mn(s) +2 Al₂O3(s) Write the net chemical equation for the production of manganese from manganese (II) carbonate, oxygen and aluminum. Be sure your equation is balanced. ol 41
