I will just tell me what you need
Answer:
it is actually b because i did this i picked b and got it right
Explanation:
3, 1, 5, 4, 3, spontaneous
If we knew the number of electrons in the outermost shell, the valence electrons, then we could find the valency of the element by calculating how many electrons need to be gained or lost to achieve stable electronic configuration.
For example, if an element has 7 valence electrons, and requires 8 valence electrons to be stable, then its valency will be -1.
To solve this we assume that the sample gas is an
ideal gas. Then, we can use the ideal gas equation which is expressed as PV =
nRT. At a constant pressure and number of moles of the gas, the ratio T/V is
equal to some constant. At another set of condition of temperature, the
constant is still the same. Calculations are as follows:
T1 / V1 = T2 / V2
V2 = T2 x V1 / T1
V2 = 350 K x 500 mL / 150 K
<span>V2 = 1166.67 mL</span>

<span>Therefore, the new volume of the system from the temperature change would be 1166.67 mL or about 1.2 L.</span>
