Following are the pair of elements that result in an ionic compound
Option A and B
<u>Explanation:</u>
- Ionic compounds are defined as the compound that consists of ions held by two atoms of differently charged ions.
- These compounds have a positive charge of ions called cations and a negatively charged element is anions.
- In the above options, we shall say that the atoms such as Ca and K both result in cations as they release an electron to become a positive ion.
- Also, Cl and S both result in anions as they attract more electron to form negative ions.
- These positive and negative ion together results in an ionic compound.
Answer:
Option C. By increasing the temperature
Explanation:
From the graphical illustration above, we see clearly that the volume and temperature of the gas are directly proportional. This implies that as the temperature increases, the volume will also increase and as the temperature decreases, the volume will also decrease. This can further be explained by using the ideal gas equation as shown below:
PV = nRT
P is the pressure.
V is the volume.
n is the number of mole.
R is the gas constant.
T is the temperature.
PV = nRT
Divide both side by P
V = nRT/P
Since n and P are constant, the equation above becomes:
V & T
V = KT
K is the constant.
The above equation i.e V = KT implies that:
As T increases, V will also increase and as T decreases, V will also decrease.
Considering the question given above,
The volume of the gas can be increased if the temperature is increased.
