Hey there!
There is a coefficient of 10 in front of water, and a coefficient of 1 in front of the salt.
This means that for every one mole of salt, there is 10 moles of water.
The mole ratio of salt to water is 1 to 10, or 1:10.
Hope this helps!
We are given the number of moles of solid magnesium supplied for the reaction which is 0.02 moles while hydrochloric acid is supplied in excess thus we can say that the reaction proceeds to completion. Calculation is as follows:
0.020 mol Mg ( 1 mol H2 / 1 mol Mg ) = 0.020 mol H2 gas is produced
To convert the number of moles to volume, we use the conditions at STP of 1 mol of a substance is equal to 22.4 L. Thus,
0.020 mol H2 (22.4 L / 1 mol) (1000 mL / 1 L) = 448 mL
Answer:
→A space heater warms a room⇒By converting electrical energy into heat energy.
→You eat dinner⇒Our body uses chemical energy to break down the food
→A radio plays⇒By converting electrical energy into sound energy in an electric radio. And by converting chemical energy into sound energy in a radio which runs with a cell.

this is because more than 1/3 of the country's land is being used for this mean alone.
When the sun becomes active, the occurrences of phenomena such as solar flares, coronal mass ejection become frequent. The amount of high-energy particles and extreme shortwave radiation released, such as X-rays and UV, will also increase. These phenomena affect the ionosphere of the Earth's atmosphere the most.
