Answer:
greenhouse effect
Explanation:
Greenhouse effect -
It is the process by which the radiations on the planet gets trapped inside its atmosphere and increases the temperature of the planet , is referred to as the process of greenhouse effect .
Few gases are responsible to show this process , like carbon dioxide . methane , water vapour etc.
The process of greenhouse is important for the planet to sustain life , as it makes the planet warm and thereby don't allow the planet to freeze ,
But excess of greenhouse effect can make the planet extremely warm , and lead to a condition of global warming .
Hence , from the given information of the question ,
The correct answer is greenhouse effect .
Answer:
3 you use elements instead of numbers and arrows instead of equal signs
actually it would be more like word problems you have 4 apples plus 3 oranges yields 7 apple orange things but it doesn't yield 7 of them it would be an equal ratio of moles of the fruits
4 the arrow is an equal sign
Explanation:
Percentage by mass is the mass of NaF present in 100 g of the solution.
the percentage by mass of NaF is 23.4 %
this means that in 100 g of solution, mass of NaF present is 23.4 g
the number of moles of NaF present - 1.33 mol
mass of NaF - 1.33 mol x 42 g/mol = 55.9 g
when there's 23.4 g of NaF - mass of solution is 100 g
therefore when there's 55.9 g of NaF - mass of solution is 100 / 23.4 x 55.9
= 239 g
mass of solution required is 239 g
