Why is strontium more reactive than calcium but less reactive than rubidium?
1 answer:
Sr is below Ca and to the right of Rb in the Periodic Table (see the attached image).
Reactivity increases from <em>top to bottom of a Group</em>. Sr is below Ca, so it is <em>more reactive</em> than Ca.
Reactivity decreases from <em>left to right in a Period</em>. Sr is to the right of Rb, so it is <em>less reactive</em> than Rb.

Scale is defined as the measurement of unit ranges, that has been corresponds to the measurements.
The units for the measurement of temperature are given as:
The scale used for the measurement of the freezing is the temperature scale. The temperature is measured in the units of Kelvin, Fahrenheit , and Celsius.
The unit scale for the measurement of freezing of water are
- Freezes at 32 - In the Fahrenheit scale
- Freezes at 0 - In the Celsius scale
- Freezes at 273 - In the Kelvin scale

<h2>Hello!</h2>
The answer is:
The new volume will be 1 L.
To solve the problem, since we are given the volume and the first and the second pressure, to calculate the new volume, we need to assume that the temperature is constant.
To solve this problem, we need to use Boyle's Law. Boyle's Law establishes when the temperature is kept constant, the pressure and the volume will be proportional.
Boyle's Law equation is:
So, we are given the information:
Then, isolating the new volume and substituting into the equation, we have:
Hence, the new volume will be 1 L.
