Answer: 0.62 M
Explanation:
molarity = (moles of solute)/(liters of solution)
- If we approximate the atomic mass of Na to be 23 g/mol and the mass of Cl to be 35.5 g/mol, then the formula mass of NaCl is 58.5 g/mol.
- This means that 32 grams of NaCl is about 32/58.5 = 0.547 mol.
Hence, the molarity is (0.547)/(.88) = 0.62 M (to 2 s.f.)
Answer:
Mg₃(PO₄)₂
Explanation:
Note: The phosphate ion is PO₄³⁻
3Mg⁺² + 2PO₄³⁻ => Mg₃(PO₄)₂
Answer:warm
Explanation: because it is in the southern hemisphere so in the winter while the northern hemisphere is in a cold winter the southern hemisphere is in a warm winter due to it being in the southern hemisphere where temperatures are really warm in the southern hemisphere.

For a reaction involving sodium hydroxide and hydrochloric acid, the balanced equation of reaction is:
For a reaction involving sodium hydroxide and acetic acid, the balanced equation of reaction is:
For a reaction involving sodium hydroxide and phosphoric acid, the balanced equation of reaction is:
The number of sp2 hybrid orbitals on the carbon atom in CO32– is 3. Because hybrids = combination of 2 different types of orbitals
sp2 = 1/3 s character + 2/3 p character
