The law which this chemist is most likely investigating heating a fixed amount of gas in a sealed glass container is: Gay Lussac’s law.
Gay Lussac's law states that when the volume of an ideal amount of gas is held (kept) constant, the pressure of the gas is directly proportional to the absolute (Kelvin) temperature of the gas.
Mathematically, Gay Lussac's law is calculated by using the formula;
<u>Where:</u>
is the original pressure.
is the final pressure.
is the original temperature.
is the final temperature.
In conclusion, the chemist is most likely investigating how changes in temperature affect the pressure of the gas by heating a fixed amount in a sealed glass container in accordance with Gay Lussac's law.

Answer:- 0/+1e
Solution:- For the nuclear equations, the sum of mass numbers of reactants must be equal to the products. Similarly, the sum of atomic numbers of reactants must be equal to the products.
For the given reaction, The atomic number for reactant side is 56 and for the product side it is 55. To make them equal, the atomic number of the unknown product must be 1.
Mass number of the reactant side is 124 and the product side is also 124. Since it's already equal, the mass number of the unknown must be 0.
Since there is a decrease in atomic number by one unit, it is +beta decay reaction. beta particle is positron which is positively charged electron. So, the right choice is 0/+1e and the equation is written as:
Answer:
The answer is
<h2>2 cm/year</h2>Explanation:
To find the rate in cm/year we must first convert 200 m into cm
1 m = 100 cm
if 1 m = 100 cm
Then 200 m = 200 × 100 = 20 ,000 cm
So the rate is
<h2><u>Reduce the fraction with 10,000</u>
We have the final answer as
<h3>2 cm/year</h3>Hope this helps you
