Which statement describes a step in the formation of an ionic bond?
BartSMP [9]
The correct answer is  a metal atom forms a cation, and a nonmetal atom forms an anion.  This is because metals are less electronegative than nonmetals and will therefore give electrons to nonmetals.  Atoms that give up electrons will have a positive charge therefore becoming a cation while atoms that accept electrons will have a negative charge therefore becoming an anion.


Ions that have the same charge can't be attracted to each other since it takes a positive and negative charge to cause attractive forces. 

A less electronegative atom will transfer electrons to a more electronegative atom.

A metal (cation) can pull electrons from another metal (not an ion) but that does not form an attractive force between the two metals (You will learn more about this when you go over reduction potentials, redox reactions, and electrochemistry).

I hope this helps.  Let me know if anything is unclear.

How many grams are in 11.9 moles of chromium?
raketka [301]

Explanation:

It is known that one mole of chromium or molar mass of chromium is 51.99 g/mol.

It is given that number of moles is 11.9 moles.

Therefore, calculate the mass of chromium in grams as follows.

     No. of moles = \frac{mass in grams}{Molar mass}

    mass in grams = No. of moles × Molar mass

                             = 11.9 moles × 51.99 g/mol

                             = 618.68 g

Thus, we can conclude that there are 618.68 g in 11.9 moles of chromium.

Which energy source from a reservoir would provide affordable, abundant electricity for a factory? solar panels wind turbines ga
Sunny_sXe [5.5K]

The energy source from a reservoir would provide affordable, abundant electricity for a factory is a hydroelectric power plant; option D.

<h3>What is energy?</h3>

Energy is the ability to do work.

Energy generating plants may either use wind, water or solar energy to produce electrical energy.

The most abundant source of energy from a reservoir is hydroelectric power plant.

Therefore, the energy source from a reservoir would provide affordable, abundant electricity for a factory is a hydroelectric power plant.

In conclusion, hydroelectric power plants are reservoirs of abundant energy supply.

Which statement best compares and contrasts two physical properties of matter? Density and solubility are similar because they b
mash [69]
I believe the correct answer would be that b<span>oiling points and melting points are similar because they both involve the change in a state of a material, but they are different because boiling point involves a change from a liquid to a gas and melting point involves a change from a solid to a liquid. Boiling and melting are phase changes that can happen to a substance however they differ in the process that happens.</span>
