5 0

Answer:

The force exerted on it.

Explanation:

As the law of motion states, an object at rest will remain at rest an object in motion will remain in motion unless acted upon by another force.

Identify the spectator ions in this reaction:<br> 2H+ + 2NO3- + Ca2+ + 2OH- → Ca2+ + 2NO3 + 2H20
inysia [295]

Answer:

Explanation:

2NO3, Ca2+

Spectator ions exists in both sides of the equation. These ions are present in both sides thus cancel out (they do not contribute to reaction...i.e. they only watch or spectate ;) )

if 0.3 moles of carbon reacts completely with 0.3 moles of molecular oxygen, what is the yield in Percent of 6.6 g of CO2 are fo
Anettt [7]
Answer is:<span>the yield is 50%.
</span>
Chemical reaction: C + O₂ → CO₂.
n(C) = 0.3 mol; amount of substance.
n(O₂) = 0.3 mol.
From chemical reaction: n(C) : n(CO₂) = 1 : 1.
n(CO₂) = 0.3 mol.
M(CO₂) = 44 g/mol; molar mass of caron(IV) oxide.
m(CO₂) = n(CO₂) · M(CO₂).
m(CO₂) =0.3 mol · 44 g/mol.
m(CO₂) = 13.2 g; mass of carbon(IV) oxide.
the yield = 6.6 g ÷ 13.2 g · 100%.
the yield = 50%.

What happens to the average kinetic energy of a gas when the particles of the gas collide against each other at a constant tempe
LuckyWell [14K]

Answer:

The average kinetic energy drastically increases.

Explanation:

The average kinetic energy drastically increases when the gas particles collide against each other at a constant temperature and volume because the collision will increase the heat content of gas at a particular temperature and gas particles begin to move faster as gain more kinetic energy.

Hence, the correct answer is "B".
