Answer : The boiling point of the solution is
Explanation :
Formula used for Elevation in boiling point :
or,
where,
= boiling point of solution = ?
= boiling point of water =
= boiling point constant of water =
m = molality
i = Van't Hoff factor = 1 (for non-electrolyte)
= moles of solute (ethylene glycol) = 0.75 mole
= mass of solvent (water) = 1 kg
Now put all the given values in the above formula, we get:
Therefore, the boiling point of the solution is
Answer:
more negative
Explanation:
There are various variants of Coviid virus. The Brazilian variant P also known as Gamma variant is the third variant of the original SARS-CoV2. This variant has raised concerns since it has ability to spread more quickly then previous variants and this is more negative variant. It is assumed that Coviid variant Gamma and Delta has ability to absorb move UV light but this is not proved yet and research is underway.
CaCO3
In a synthesis reaction, two substances combine to make a third substance:
A + B → C
The product (C) must contain all the atoms that were in A and B.
Thus, the reaction must be
CaO + CO2 → CaCO3
The product is CaCO3.
False, it would be considered 9.46 * 1,000,000,000,000,000
