How much energy is added to change 180g of liquid water to gas at 100 degrees Celsius

Chemistry
1 answer:
Finger [1]2 years ago
7 0

Answer:

40.7 kJ  

Step-by-step explanation:

The formula for the heat, q, needed to evaporate a liquid is

q = mΔHvap


<em>Data:  </em>

        m = 180 g

ΔHvap = 2260 J/g

<em>Calculation: </em>

q = 180 g × 2260 /1

q = 40 700 J = 40.7 kJ

Jobisdone [24]
Phosgene on reacting with <span>phenylmagnesium bromide generates benzoyl chloride. 

Since, </span>phenylmagnesium bromide is added in excess. It would further react with benzoyl chloride to form benzophenone.

Benzophenone on further reacting with phenylmagnesium bromide, and aqueous treatment, gives triphenylmethanol.

Name the 2 isomers of c7h16 that contain 2 methyl branches, each branch on a different carbon of the parent chain.
kupik [55]
There can be a lot of meanings for isomers. In this case, we are showing the structural isomers of C₇H₁₆. Based on the chemical formula, CₓH₂ₓ₊₂ it is an alkane. They only differ in the positions of methane branches in the parent carbon chain. Basing on the attached picture, the parent carbon chain is pentane for both isomers. But the methyl branches are on the 2nd & 4th, and 2nd & 3rd carbon for 2,4 - dimethylpentane and 2,3 - dimethylpentane, respectively.

soldi70 [24.7K]

Answer:

The elastic potential energy stored in the stretched rubber band changes to kinetic energy.

Explanation:

Joshua hooks a rubber band between his thumb and forefinger. He moves his fingers apart, stretching the rubber band---- Here potential Energy is stored which is an energy that the rubber band has because of its position and it's potential to be converted into kinetic energy.

With a quick, sudden motion, he bends his thumb forward so that the rubber band slips off----The elastic potential energy stored in the stretched rubber band will change to kinetic energy, which is the Energy in Motion and work needed to accelerate the rubber band from rest to its stated or new position.

How many grams are in 9.05 x 1023 atoms of silicon?
Sergeu [11.5K]

Explanation:

Number of moles(n)=Number of atoms(N)/Avogadro's constant.

Avogadro's constant=6.02×10²³

so we have

n=9.05×10²³/6.02×10²³

n=1.0503moles.

n=mass/molar mass

1.0503=mass/28

mass=1.0503×28

mass=29.4084g
