For this question use the main assumptions of the Kinetic Molecular Theory of gases: 1. Gases are made up of molecules which are

relatively far apart. 2. The molecules are in motion at high speeds. 3. The molecular collisions are perfectly elastic. 4. Increase in temperature increases the kinetic energy of the molecules. The idea that no energy is lost when gas molecules hit the walls of a container or each other is explained by 1 2 3 4

Answer:

Number 3

Explanation:

No energy is lost because collisions are perfectly elastic. Therefore, the answer is number 3.

What does an arrow in a chemical equation show?
kobusy [5.1K]

Answer:

A chemical equation consists of the chemical formulas of the reactants (on the left) and the products (on the right). The two are separated by an arrow symbol (“→” usually read aloud as “yields”). ... The equation also identifies that all the compounds are in the gaseous state.

In the early 1960s, radioactive strontium-90 was released during atmospheric testing of nuclear weapons and got into the bones o
Advocard [28]

Answer:

52.54 %

Explanation:

Half life = 29 years

t_{1/2}=\frac {ln\ 2}{k}

Where, k is rate constant

So,  

k=\frac {ln\ 2}{t_{1/2}}

k=\frac {ln\ 2}{29.0}\ {years}^{-1}

The rate constant, k = 0.023902 hour⁻¹

From 1964 to 1991:

Time = 27 years

Using integrated rate law for first order kinetics as:

[A_t]=[A_0]e^{-kt}

Where,  

[A_t] is the concentration at time t

[A_0] is the initial concentration

So,  

\frac {[A_t]}{[A_0]}=e^{-0.023902\times 27}

\frac {[A_t]}{[A_0]}=0.5245

<u>The strontium-90 remains in the bone = 52.54 %</u>
