Answer» ★ Answer : Mass by volume % = $\dfrac{Mass \: by \: solute(g)}{Volume \: of \:<klux>SOLUTION</klux>(ml)} \times 100$ Given : Copper SULPHATE (mass of solute) = 105 g Volume of water (volume of Solution) = 500 ml Solution : by PUTTING the values.. Mass by volume % = $\dfrac{105}{\cancel{500}} \times \cancel{100}$ $= \dfrac{105}{5} = 21$ $\leadsto \therefore \: mass \: by \: volume \: \% = 21 \%$ ★ Additional INFORMATION: Mass % = $\dfrac{Weight \: of \: solute(g)}{Weight\:of \: Solution(g)}$ Volume % = $\dfrac{Volume \: of \: solute(ml)}{Volume\:of \: Solution(ml)}$

If 105 g of copper sulphate is dissolved in 500 ml of water, calculate the mass by volume percentage of this solution.Plz answer

Answer»

★ Answer :

Mass by volume % =

$\dfrac{Mass \: by \: solute(g)}{Volume \: of \:<klux>SOLUTION</klux>(ml)} \times 100$

Given :

Copper SULPHATE (mass of solute) = 105 g

Volume of water (volume of Solution) = 500 ml

Solution :

by PUTTING the values..

Mass by volume % =

$\dfrac{105}{\cancel{500}} \times \cancel{100}$

$= \dfrac{105}{5} = 21$

$\leadsto \therefore \: mass \: by \: volume \: \% = 21 \%$

★ Additional INFORMATION:

Mass % = $\dfrac{Weight \: of \: solute(g)}{Weight\:of \: Solution(g)}$

Volume % = $\dfrac{Volume \: of \: solute(ml)}{Volume\:of \: Solution(ml)}$

Answer» Answer: o far we have discussed temperature change due to heat transfer. No temperature change occurs from heat transfer if ice melts and becomes LIQUID water (i.e., during a phase change). For example, consider water DRIPPING from icicles melting on a roof warmed by the Sun. Conversely, water FREEZES in an ice tray cooled by lower-temperature surroundings. Heat from the AIR transfers to the ice CAUSING it to melt. (credit: Mike Brand

485.	Out of elements 17 X 34 and 18 Y 40, which is chemically more reactive and why?
Answer» Explanation: Out of elements 34X17 and 40X18, the element 34X17 is chemically more reactive. The element 34X17 and 40X18 contains 17 and 18 ELECTRONS respectively. The electronic configuration of 34X17 is 1s2,2s2,2p6,3s2,3p5 and the electronic configuration of the element 40X18 is 1s2,2s2,2p6,3s2,3p6. The element with 18 electrons has a fully filled outermost SHELL and in its octet hence will have lesser tendency to either lose or gain electrons than the element with 17 electrons which NEEDS one electron to complete its octet. Hence, 34X17 is more reactive than 40X18.

Out of elements 17 X 34 and 18 Y 40, which is chemically more reactive and why?

Answer»

Explanation:

Out of elements 34X17 and 40X18, the element 34X17 is chemically more reactive.

The element 34X17 and 40X18 contains 17 and 18 ELECTRONS respectively.

The electronic configuration of 34X17 is 1s2,2s2,2p6,3s2,3p5 and the electronic configuration of the element 40X18 is 1s2,2s2,2p6,3s2,3p6.

The element with 18 electrons has a fully filled outermost SHELL and in its octet hence will have lesser tendency to either lose or gain electrons than the element with 17 electrons which NEEDS one electron to complete its octet.

Hence, 34X17 is more reactive than 40X18.
