Which type of renewable energy creates electricity by using water currents to spin a turbine?
vovangra [49]

Answer:

Hydropower

Explanation:

I learn whenever Hydro is in a word it means water

Also in the question it is talking about water and wind, solar, nor Biomass has anything to do with water, so you can use the process of elimination and find you will only have Hydropower left.

Hope this helps

How many moles of carbon dioxide are produced from the reaction of oxygen with four moles of propane (C3H8)? C3H8 + 502 —> 3C
BigorU [14]

Answer:

12 moles

Explanation:

1. Do comparison

From the equation, 1 mole of C3H8 yields 3 moles of CO2

Therefore, 4 moles of C3H8 should yield 12 moles of CO2

Steps:

Number of moles of CO2

= (1 mol x 4) x 3

= 12 moles

Students working in lab accidentally spilled 17 l of 3.0 m h2so4 solution. they find a large container of acid neutralizer that
bogdanovich [222]

Answer is: 8568.71 of baking soda.

Balanced chemical reaction: H₂SO₄ + 2NaHCO₃ → Na₂SO₄ + 2CO₂ + 2H₂O.

V(H₂SO₄) = 17 L; volume of the sulfuric acid.

c(H₂SO₄) = 3.0 M, molarity of sulfuric acid.

n(H₂SO₄) = V(H₂SO₄) · c(H₂SO₄).

n(H₂SO₄) = 17 L · 3 mol/L.

n(H₂SO₄) = 51 mol; amount of sulfuric acid.

From balanced chemical reaction: n(H₂SO₄) : n(NaHCO₃) = 1 :2.

n(NaHCO₃) = 2 · 51 mol.

n(NaHCO₃) = 102 mol, amount of baking soda.

m(NaHCO₃) = n(NaHCO₃) · M(NaHCO₃).

m(NaHCO₃) = 102 mol · 84.007 g/mol.

m(NaHCO₃) = 8568.714 g; mass of baking soda.
