Answer:
A. Elements
Elements are substances that cannot be separated into simpler substances. Salt is made up of the elements sodium and chloride. Water is made up of the elements hydrogen and oxygen, to list a few.
Answer:
c . a proton
Protons and neutrons have approximately the same mass, about 1.67 × 10−24 grams
Answer:
Explanation:
A) O2 (non polar covalent)
B) HF (polar covalent)
C) NaCl (because its ionic)
im not 100% sure hope it helps
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.
K⁺ has positive charge, the easiest way to form a bond is to connect to negatively charged ion. We have only one negative ion Cl⁻.
So, the answer is
C. Cl⁻.
