Answer:
I'm pretty sure it's b
Explanation:
C and D don't make my b sense, you can't magnetize an animal or shells, and settling doesn't sound like it's right, so I would personally go with B
A. zinc
Explanation:
Zinc and Cadmium are in the same group. Elements in the same group have similar characteristics and properties. Hope this helps!
Methane, CH4, would have the lowest boiling point among the three since it has the lowest number of carbon and has no functional groups. Methanol would have the highest boiling point since it has a functional group which contains hydrogen bonding which much stronger than the one in CH3Cl. Hope this helps.<span />
Answer:
514.53 g.
Explanation:
- The balanced equation of the reaction is:
2NaOH + H₂SO₄ → Na₂SO₄ + 2H₂O.
- It is clear that 2.0 moles of NaOH reacts with 1.0 mole of H₂SO₄ to produce 1.0 mole of Na₂SO₄ and 2.0 moles of H₂O.
- The limiting reactant is NaOH and H₂SO₄ is an unlimited reactant.
- We can calculate the no. of moles of H₂SO₄ using the data available:
n = mass / molar mass = (355.0 g) / (98.0 g/mol) = 3.62 mol.
<em>Using cross multiplication; </em>we can calculate the no. of moles of sodium sulfate Na₂SO₄ can the reaction produce:
1.0 mole of H₂SO₄ produces → 1.0 mole of Na₂SO₄, from the stichiometry.
3.62 moles of H₂SO₄ produces → ??? mole of Na₂SO₄.
- The no. of moles of sodium sulfate Na₂SO₄ can the reaction produce = (1.0 mol)(3.62 mol) / (1.0 mol) = 3.62 mol.
- Now, we can calculate the grams (mass) of sodium sulfate Na₂SO₄ can the reaction produce = n x molar mass = (3.62 mol)(142.04 g/mol) = 514.53 g.
Hello,
I'm not very sure but I think the correct answer is D) Water Wave
I really hope this helps!!!! Happy Holidays!!!! (:
