You need 0.111 g of NH₃ to provide the same number of molecules as
in 0.95 g of SF₆.
<em>Step 1</em>. Convert grams of SF₆ to moles of SF₆
Moles of SF₆ = 0.95 g SF₆ × (1 mol SF₆/146.06 g SF₆) = 0.006 50 mol SF₆
Now, we can use the knowledge that <em>1 mol of anything has the same number of molecules</em> (Avogadro’s number) <em>as 1 mol of anything else</em>
.
Thus, 0.006 50 mol NH₃ has the same number of molecules
as 0.006 50 mol SF₆.
<em>Step 2</em>. Convert moles of NH₃ to grams of NH₃.
Mass of NH₃ = 0.006 50 mol NH₃ × (17.03 g NH₃/1 mol NH₃) = 0.111 g NH₃
Answer:
La Nina
Explanation:
La Nina -
The word La Nina means " the little girl " , in spanish language .
La Nina , is an ocean - atmospheric process , which occurs in the eastern equatorial Pacific Ocean .
It is exactly opposite of El Nino , which means " the little boy " .
In the phase of La Nina , the temperature of the eastern equatorial Pacific Ocean becomes lower than the usual temperature by around 3°C to 5°C .
This phase of La Nina is for around 5 months in an year .
Hence , from the given statement of the question ,
The correct term is La Nina .

Answer:
A continuous spectrum contains many different colors, or wavelengths, with no gaps. Perfectly white light shined through a prism causes dispersion of the light, and we see a rainbow. Conversely, when a gas is heated, the atoms in the gas absorb the energy and emit light, and an emission spectrum results.

Explanation:
A chemical formula can be defined as a notation that is used to show which element and how many is contained in a chemical compound.
Also, in chemistry, the sum of charges of the anion and the cation of any ionic compound is always equal to zero.
A chemical equation is considered to be balanced when the amount of reactants on the left is equal to the amount of products on the right.
Therefore;
[2]FeBr3 + [3]Na2S → [1]Fe2S3 + [6]NaBr
In the above chemical equation, we will balance the reactants in the chemical equation with the smallest coefficients possible;
Two (2) moles of Iron (III) Bromide reacts with two (2) moles of Sodium Sulfide to form Iron (III) Sulfide and Sodium Bromide.
