Chemistry

Elza [17]3 years ago

Answer:

C. Heat must be added or removed

Explanation:

When matter changes states it is due to the overall loss or gain of heat. In addition, heat being added or removed is what will cause a temperature change, but a simple temperature change is not enough to change states. For example, a temperature could go from 50 degrees to 51. This will not cause a change in states. So heat must be added or removed in order for matter to change states.

Waves transport water in the deep ocean toward the coastlines. True or false
ASHA 777 [7]

Answer:

Most likely true

Explanation:

because the speed of all ocean waves is controlled by gravity, wavelength, and water depth. ... Waves moving through water deeper than half their wavelength are known as deep-water waves. On the other hand, the orbits of water molecules in waves moving through shallow water are flattened by the proximity of the sea surface bottom.

Mass of N₂ will be formed : 50.12 g

<h3>Further explanation</h3>

Reaction

2 NH₃(g) + 3 CuO(s) → N₂(g) + 3 Cu(s) + 3 H₂O(g)

moles NH₃ = 3.58

ratio mol NH₃ : mol N₂ = 2 : 1

so mol N₂ :

\tt \dfrac{1}{2}\times 3.58=1.79

mass N₂ (MW=28 g/mol) :

\tt 1.79\times 28=50.12~g
