Answer:

wind, solar, bioproduction

Explanation:

The wind energy, since in some places the wind reaches fast velocities, the scientist try to implement new technology to improve how to convert wind energy in electricity for example.

The solar energy, even we have by now the solar panels, there is still an area to research to obtain again the mayor quantity of energy with less materials.

The bioproduction, since the mammals we produce liquid and solid wastes, how to convert it into energy like gas, electricity, etc.

For the first one, you have to find one that has both a metal and a nonmetal in it, plus potassium. Bonds between nonmetals are called covalent because they share electrons and a bond between a metal and a nonmetal is an ionic bond because they exchange electrons.

Potassium chloride is KCl. Only an ionic bond.

Potassium hydride is KH. Only an ionic bond.

Potassium nitrate is KNO3. There we go, that has a covalent bond between the nitrogen and oxygen, and an ionic bond between potassium and the nitrogen and oxygen.

For the second one, potassium chloride is the answer because the other three also have covalent bonds. Chloride is the only one that isn't a compound.

How to calculate from moles to grams?<br> 4.0 moles of Cu(CN)2
andreyandreev [35.5K]

Answer: The mass of given amount of copper (II) cyanide is 462.4 g

Explanation:

To calculate the number of moles, we use the equation:

We are given:

Moles of copper (II) cyanide = 4 moles

Molar mass of copper (II) cyanide = 115.6 g/mol

Putting values in above equation, we get:

Hence, the mass of given amount of copper (II) cyanide is 462.4 g
