Answer:
A substance that is comprised of more than one kind of atom reinforced together. Blend: A mix of at least two components or mixes that have not responded to bond together; each part in the combination holds its own properties.
Explanation:

The total pressure of the mixture of gases is
equal to the sum of the pressure of each gas as if it is alone in the
container. The partial pressure of a component of the mixture is said to be
equal to the product of the total pressure and the mole fraction of the
component in the mixture.<span>
Partial pressure of hydrogen gas = 1.24 atm x
.25 = 0.31 atm
<span>Partial pressure of the remaining = 1.24 atm x
(1-.25) = 0.93 atm </span></span>
List of the metals that form only one type of ion (that is, metals whose charge is invariant from one compound to another) is below,
Here , we have to list the metals that form only one type of ion (that is, metals whose charge is invariant from one compound to another) and have to identify the group numbers of these metals.
- Hydrogen H+
- Lithium Li+
- Sodium Na+
- Potassium K+
- Rubidium Rb+
- Cesium Cs+
- Beryllium Be2+
- Magnesium Mg2+
- Calcium Ca2+
- Strontium Sr2+
- Barium Ba2+
- Aluminum Al3+
- Zinc Zn2+
- Scandium Sc3+
- Silver Ag+
Co is stable in both +2 and +3 oxidation state. So it can variable. Li only have +1 charge. So it is invariable from one compound to other.
