Use the following equation to answer the questions below. CH4 (g) + 2O2 (g) → CO2 (g) + 2H2O (g)

1. What type of reaction is this? Why do you say it is this type of reaction? Support your claim with evidence. (2 points, 1 point valid type of reaction, 1 point valid evidence)

2. What is the mole ratio of methane to water in the reaction? (1 point correct mole ratio)

3. How many moles of water are produced from the reaction of 50.0g of methane (CH4)? Show your work (2 points, 1 point valid answer, 1 point valid work)

Calcium hydride (cah2) reacts with water to form hydrogen gas: cah2(s) + 2h2o(l) → ca(oh)2(aq) + 2h2(g) how many grams of cah2 are needed to generate 45.0 l of h2 gas at a pressure of 0.995 atm and a temperature of 32 °c?

What shape would a molecule with two bound groups and two lone pairs have?

Plzz a sample of table sugar (sucrose, c12h22o11) has a mass of 7.801 g. ● a) calculate the number of moles of c12h22o11 in the sample b) calculate the number of moles of each element in c12h22o11 (number of moles of c, number of moles of h & number of moles of o) in the sample. (use your answer from part a as your starting point.) show your work and highlight your final answer. calculate the number of atoms of each element in c12h22o11 (number of atoms of c, number of atoms of h & number of atoms of o) in the sample. (use your answers from part b as your starting for each element.) show your work and highlight your final answer.
