Answer:
alkaline earth metal
it's because calcium in the periodic table is located in group 2
Answer: 1. The solvent in a mixture of gases is generally considered to be the substance in greater amount. 2. The solid dissolved in a solution is known as the solute. 3. Solid solutions are called alloys.
Explanation:
A binary solution is made up of two components ,called as solute and another as solvent.
A solute is defined as the component which is present in smaller proportion. It can be in solid, liquid or gaseous phase. A solvent is defined as the component which is present in larger proportion in a solution. It can be in solid, liquid or gaseous phase.
Usually in liquid solutions , solid acts as solute and liquid acts as solvent. For example: In salt solution, salt is the solute and water is the solvent.
Solid solutions contains solid as solute and solid as solvent. These are called as alloys. For example : In brass, zinc is the solute and copper is the solvent.
Answer:
A bond forms between two non metals is covalent
Explanation:
For example Chlorine Cl is a non metal bond in Cl - Cl is covalent
Answer:
The total pressure P = 1.642 atm
Explanation:
From the dalton's law
Total pressure of the mixture is
----- (1)
atm
atm
n = 0.24 mole
R = 
T = 41 °c = 314 K
= 0.634 atm
From equation (1)
P = 0.419 + 0.589 + 0.634
P = 1.642 atm
Thus the total pressure P = 1.642 atm
