1.16 g of UF₄ can be formed in this reaction.
<u>Explanation:</u>
We have to write the balanced equation of the reaction between Uranium oxide and hydrogen fluoride to form Uranium tetra fluoride and water as,
UO₂(s) +4 HF(aq) → UF₄ + 4 H₂O(l)
We can find the moles of UF₄ and then multiplying molar mass of UF₄ with the moles of UF₄, we will get the mass of UF₄ in grams.
Moles of UF₄ = 
= 0.00370 mol UF₄
Grams of UF₄ =0.00370 mol × 314.02 g/mol = 1.16 g of UF₄
So mass of UF₄ formed in the reaction is 1.16 g.
The answer is B. Unit cell.

Answer:
Answer to the following question is as follows;
Explanation:
A millilitre is equal to the volume of a cube with 1 cm on each side. As a result, one millilitre equals one cubic centimetre. There are 1000 mL in a litre, that is the same as 1000 cm3 in a square metre.
1 ml = 1 cm³
1000 ml = 1 liter
The best and most correct answer among the choices provided by your question is the third choice or letter C.
<span>The mole is most similar to a dozen which is a measure of number.</span>

Answer:
60.7%
Explanation:
Molar mass of NaCl = 23 +35.5
= 58.5 g/mol
Molar mass of Cl = 35.5 g/mol
Percentage by mass of Cl =?
The percentage by mass of Cl in NaCl can be obtained as shown below'
Percentage by mass = mass of element / mass of the compound × 100
Percentage by mass of Cl
= 35.5 / 58.5 × 100
= 3550 / 58.5
= 60.7%
Therefore, the percentage by mass of Cl in NaCl is 60.7%
