The distance between molecules INCREASES when the substance vaporizes
Explanation:
The distance between the molecules increase due to the fact that as you put more energy into the substance the kinetic energy of the molecules increases. This means they are vibrating more vigorously and the collision between the molecules are becoming more energetic. This means the collisions fling the molecules far away from each other (due to their increased momentum) hence the increased average distance between molecules.

Answer:
Acetic acid is a weak monoprotic acid.
In aqueous solution it has a pKa value of 4.76.
It conjugate base is acetate (CH3COO-) A 1.0m
solution ( about the concentration of domestic vinegar) has pH of 2.4, *indicating that merely
0.4% of the acetic acid molecules are dissociated.

Answer:
0.7644 moles of H₂O
Explanation:
The balance chemical equation is as follow;
2 H₂O₂ → 2 H₂O + O₂
To solve this problem we will first calculate the moles of H₂O₂ as,
Moles = Mass / M/Mass
Moles = 26.0 g / 34.01 g/mol
Moles = 0.7644 mol
Secondly,
According to equation,
2 moles of H₂O₂ produces = 2 moles of H₂O
Hence,
0.7644 mol of H₂O₂ will produce = X moles of H₂O
Solving for X,
X = 2 mol × 0.7644 mol / 2 mol
X = 0.7644 moles of H₂O
<h2><u>Answer:</u></h2>
Lico. The stone was unclear range from the including territory. Between 130 million and 500 million years back, magma from volcanoes cooled to shape the stone that would advance toward getting to be Mt.
On Mount Lico in northern Mozambique is a site that few have had the enjoyment of seeing – a hid rainforest, verified by an unsafe float of shake. In spite of the way that the mountain was known to neighborhood individuals, the forested areas itself remained a secret until six years back, when Julian Bayliss spotted it on satellite imagery.
Pretty sure the answer is 23^4-20=54
