Ammonia gas and oxygen gas react to form water vapor and nitrogen monoxide gas. What volume of water would be produced by this r
NikAS [45]

Answer:

Water volume produced is 7.3 mL

Explanation:

This the reaction:

4NH₃ (g) + 5O₂ (g) →  4NO (g) + 6H₂O (g)

We have to work with density, to solve this question

Density of ammonia = Ammonia mass / Ammonia volume

0,00073 g/mL = Ammonia mass / 6300 mL

(Notice, we had to convert 6.3L to mL)

0.00073 g/mL . 6300 mL = Ammonia mass → 4.599 g

Mass / Molar mass = Mol

4.599 g / 17g/m = 0.270 mole

Ratio is 4:6

4 mole of ammonia produce 6 mole of water

0.270 mole produce (0.270  .6)/4 = 0.405 mol

Molar mass . mole = mass

18 g/m . 0.405 m = 7.30 g

Water density = 1 g/mL

Water density = Water mass / Water Volume

1g/mL = 7.30 g / Water volume

Water volume = 7.3 mL

The balanced chemical equation for the reaction between PCl5 and water is given below. If 3.45 moles of HCl are produced, how ma
enyata [817]
The coefficients of the substances give you the ratio of the number of moles.
The 4 before the H2O and the 5 before the HCl tell you that for every 5 moles of HCl created, 4 moles of H2O had to react.

Therefore:
(3.45mol HCl)(\frac{4 mol H2O}{5 mol HCl})
can be used to find the moles of H2O that react.

(3.45mol HCl)(\frac{4 mol H2O}{5 mol HCl}) = 2.76 mol H20

Use the drop-down menus to identify each substance as an organic or inorganic compound
dalvyx [7]

Answer:

ozone (O3): inorganic

methane (CH4): organic

aluminum hydroxide (Al(OH)3): inorganic

butane (C4H10): organic

carbon monoxide (CO): inorganic

Explanation:

An inorganic compound is typically a chemical compound that lacks carbon–hydrogen bonds, that is, a compound that is not an organic compound. Some simple compounds that contain carbon are often considered inorganic. Examples of inorganic compounds include carbon monoxide , carbon dioxide , carbonates, carbides , cyanides, cyanates, and thiocyanates. Most of these compounds are normal parts of mostly organic systems, including living organisms. When a chemical substance is classified as inorganic, it does not necessarily mean that it does not occur within

living things.

Organic compounds typically contain the carbon-hydrogen bonds. The carbon atoms often catenate and most organic substances occur in living systems and are products of biochemical reactions in living organisms. However, organic substances can also be synthetic and can be prepared in the laboratory.
