Answer:
False: <span>The major component in a solution is called the Solvent.
Explanation:
Solutions are the Homogeneous mixtures of two or more substances. Mainly the components are divided into two catogories....
1) Solvent:
The component which is the major or which is present in large amount is called solvent.
Example: In water salt solution water is the solvent.
2) Solute:
</span>The component which is the minor or which is present in less amount is called solute.
Example: In water salt solution salt is the solute.

Answer:
3520 g of CO₂
Explanation:
2C₂H₆ + 70₂ → 4CO₂ + 6H₂O
molar ratio of the above reaction is;
2 : 7 → 4 : 6
2 moles of C₂H₆ will form 6 moles of H₂O
Thus, 1 mole of C₂H₆ will form 3 moles of H₂O
mass of H₂O = 360 g
molecular weight of H₂O = 18 g/mol
molar mass = mass ÷ molecular weight = 360÷18 = 20 moles
Total number of moles of H₂O formed = 6 * 20 moles = 120 moles
Number of moles of C₂H₆ reacted = 120 moles ÷ 3 = 40 moles
molar ratio of C₂H₆ to CO₂ = 1 : 2
Thus, number of moles of CO₂ formed = 2 * 40 moles = 80 moles
molecular weight of CO₂ = 44 g/mol
mass of CO₂ formed = number of moles x molecular weight = 80 * 44 = 3520 g
Answer:
solubility
Explanation:
solubility is a measure of how much a substance will dissolve in a solvent.
Explanation: • Electronegativity is the tendency of an atom to attract the electrons in a bond towards it. • Ionization energy is the energy that should be given to a neutral atom to remove an electron from it. The difference in the electronegativity between the two elements is quite small, but the main reason for it is because chlorine is one period below oxygen. Chlorine’s valence electrons are thus less tightly bound than those of oxygen, so they would have lower first ionization energy. Does sodium or potassium have larger ionization energy?
