Answer: Condensation requires the removal of energy.

Explanation:

Condensation is defined as the process in which gaseous particles get converted into liquid particles when temperature is decreased or pressure is increased.

During this process, energy is released by the particles. When vapor comes in contact with cooler particles, they loose some energy.

Condensation is an exothermic process because energy is lost during this process.

Hence, condensation requires the removal of energy.

Fred can create 20 animal balloons every 15 minutes. solve ratio table

DerKrebs [107]

The number of animal balloons created in 15 minutes = 20

The number of animal balloons created in 1 minute = $\frac{20}{15}$

So, the number of animal balloons created in 6 minutes = $\frac{20}{15}\times 6 = 8$

And, the number of animal balloons created in 45 minutes = $\frac{20}{15}\times 45 = 60$

So, the solved ratio table will be:

$15.20$

$6.8$

$45.60$

Sodium bicarbonate is sometimes used to neutralize acid spills. If 2.0 L of 1.0 M H2SO4 is spilled, what mass of sodium bicarbon

UkoKoshka [18]

Answer:

168.0 g

Explanation:

First thing, write a balanced chemical equation:

$H_{2}SO_{4}+ 2NaHCO_{3} ----> Na_{2}SO_{4} + 2H_{2}O+2CO_{2}$

n(H2SO4) = concentration * volume

= 1.0 M * 2.0 L

= 2.0 mol

According to the balanced equation, 1 mol of acid requires 2 mol of sodium bicarbonate. This means that 2 mol of acid requires 2 mol of sodium bicarbonate. What mass of sodium bicarbonate is this?

mass (NaHCO3) = number of moles * molar mass

= 2.0 mol * 84.0065 g/mol

= 168.0 g
