A is the correct answer from what i understand in this question
Explanation:
The law of conservation of mass states that the total mass of the products is equal to the total of the reactants.
A chemical change occurs because of a chemical reaction.
In a chemical reaction, the reactants are the starting substances and the products is the finishing substances. The amount of each type of atoms to start with and end with are also equal.
No matter disappears after a chemical reaction.
Answer:
The amount of matter in the new substances is the same as the original.
This is known as the law of conservation of mass.
Answer:
30 liters
Explanation:
Since a pressure, volume, and temperature is given, this problem involves the combined gas law:
1. First, identify the given values. Make sure they are all the same units, and temperature is always in Kelvin.
<em>Your initial values:</em>
P1 = 12 atm
V1 = 23 L
T1 = 200 K
<em>Your final values:</em>
P2 = 14 atm
V2 = ?
T2 = 300 K
2. Now, plug it into the combined gas law formula. If it is easier for you, then you can rearrange the formula for V2.
3. Lastly, solve for V2.
1.38*300 = 14V2
414 = 14V2
V2 = 29.57142857142857
With sig figs, your final volume would be: 30L
Answer:
Yes, it underwent a chemical change
