The balanced chemical equation, 2no (g) + 5h2 (g) (arrow pointing this way > > ) 2nh3 (g) + 2h2o (g), can be expressed in words as:

nitrogen dioxide gas plus hydrogen gas yields ammonia gas plus water

nitrogen monoxide gas plus hydrogen gas yields ammonia gas plus water vapor

nickel monoxide gas plus hydrogen gas yields nitrogen trihydride plus water

nitrogen oxide gas plus hydrogen gas yields ammonia gas plus water vapor

i think it's either b, or d. i can't figure out which one it is though. .

1.aluminum chloride (alcl3), and sodium hydroxide (naoh) can react to form aluminum hydroxide (al(oh)3) and sodium chloride (nacl).    you have 13.4 g of aluminum chloride and 10.0 g of sodium hydroxide. answer the following questions: •what is the balanced equation for this reaction? •if you use all 13.4 g of aluminum chloride, how many grams of aluminum hydroxide can be formed? work must be shown to earn credit •if you use all 10.0 g of sodium hydroxide, how many grams of aluminum hydroxide can be formed? work must be shown to earn credit •how many grams of aluminum hydroxide will actually be made?     which reagent is limiting? explain your answer.

What type of reaction is shown below? check all that apply. 2h2o2 → 2h2o + o2 synthesis decomposition combustion

Why is the bond angle in a water molecule less than the bond angle of methane? a. the central oxygen atom in water has two lone pairs of electrons, whereas the central carbon atom in methane has no lone pairs. b. the central hydrogen atom in water has one lone pair of electrons, whereas the central carbon atom in methane has two lone pairs. c. the central oxygen atom in water has four lone pairs of electrons, whereas the central carbon atom in methane has only one lone pair. d. the central oxygen atom exerts more repulsive force on surrounding atoms than the central carbon atom in methane does. reset next
