madam [21]3 years ago
6 0

Answer:

The corrects answer are "without greenhouse gases", "reduced reliance on fossil fuels", and "renewable fuel".

Explanation:

Fuel cells are more efficient than diesel or gas engines. Most fuel cells run quietly compared to internal combustion engines, which gives you a benefit by reducing noise pollution from internal combustion engines.

Hydrogen fuel cells also have the benefit that the only by-product they eliminate is water, reducing dependence on fossil fuels because of their non-polluting appeal.

Have a nice day!

What volume of solution gives the desired moles?
motikmotik

Answer:

1. 0.073L

2. 0.028L

3. 0.014L

Explanation:

The volume for the different solutions are obtained as shown below:

1. Mole = 0.53mol

Molarity = 7.25M

Volume =?

Molarity = mole /Volume

Volume = mole /Molarity

Volume = 0.53/7.25

Volume = 0.073L

2. 0.035mol from a 1.25M

Mole = 0. 035mol

Molarity = 1.25M

Volume =?

Molarity = mole /Volume

Volume = mole /Molarity

Volume = 0.035/1.25

Volume = 0.028L

3. Mole = 0.0013mol

Molarity = 0.090M

Volume =?

Molarity = mole /Volume

Volume = mole /Molarity

Volume = 0.0013/0.090

Volume = 0.014L

stealth61 [152]
Hello!

Based on these facts, we should classify Germanium as a Metalloid.

Metalloids are chemical elements with a mixture of properties from metals and non-metals. Although Germanium has a metallic appearance (typical of metals), it doesn't have the conductive properties of metals, but is a semiconductor. The semiconductive properties of Germanium are used in applications like transistors and chips.

Have a nice day!
