Answer:
3.00 × 10²³ atoms H
Explanation:
Step 1: Given data
- Atoms of oxygen in water: 1.50 × 10²³ atoms
- Chemical formula of water: H₂O
Step 2: Calculate the number of atoms of hydrogen
According to the chemical formula of water, the atom ratio of H to O is 2:1.
1.50 × 10²³ atoms O × 2 atoms H/1 atom O = 3.00 × 10²³ atoms H
Answer:
Knetic
Explanation:
When you jump on a trampoline, your body has kinetic energy that changes over time. As you jump up and down, your kinetic energy increases and decreases with your velocity. Your kinetic energy is greatest, just before you hit the trampoline on the way down and when you leave the trampoline surface on the way up.
<u>Answer:</u> The percent change in volume will be 25 %
<u>Explanation:</u>
To calculate the final temperature of the system, we use the equation given by Charles' Law. This law states that volume of the gas is directly proportional to the temperature of the gas at constant pressure.
Mathematically,
where,
are the initial volume and temperature of the gas.
are the final volume and temperature of the gas.
We are given:
Putting values in above equation, we get:
Percent change of volume = 
Percent change of volume = 
Hence, the percent change in volume will be 25 %
