Answer:
atoms of hydrogen
Explanation:
The molecular formula for a water molecule is
.
From the above formula, we can conclude that 1 molecule of water contains 2 atoms of hydrogen and 1 atom of oxygen.
There are
molecules of water.
1 molecule of water = 2 atoms of hydrogen.
∴
molecules of water =
atoms of hydrogen.
Therefore, there are
atoms of hydrogen in
molecules of water.

A condensation reaction
Explanation:
it is also called a dehydration reaction
<h2>Answer:</h2>
This is a physical change.
<h3>
Explanation:</h3>
Hot asphalt is mixed with the sand crushed stones and spread onto the roads, when it gets dry it becomes hard giving a smooth straight surface of the road.
Asphalt is used to stick together stones and sand in the road.
It is a physical change because the phase of the asphalt changed from the liquid to solid.
At high temperature, asphalt is in liquid form and at room temperature, it is present in hard solid form.
1. The <span>student with a measurement that might be in centimeters is A. Bill.
2. C</span><span>entimeters in 0.05 kilometers is </span>C. 5,000
solution:
0.05 km x (1000 meters/ 1 km)
= 50 meters x (100 cm/ 1 meter)
=5000 cm
Butter won't melt in a fridge because of intermolecular tensions. While the bonds inside of the fat molecules are unbroken, the attractions between the fat molecules are weaker.
What intermolecular forces are present in butter?
The intermolecular forces known as London dispersion forces are the weakest and are most prominent in hydrocarbons. Due to the fact that butter molecules are hydrocarbons, London dispersion forces do exist between them.
How do intermolecular forces affect melting?
More energy is required to stop the attraction between these molecules as the intermolecular forces become more powerful. Because of this, rising intermolecular forces are accompanied with rising melting points.
Which forces are intramolecular and which are intermolecular?
Intramolecular forces are those that hold atoms together within molecules. The forces that hold molecules together are known as intermolecular forces.
