The process of changing chemical energy into another form of energy is called chemical change.

Actually the other person's answer is wrong, chemical energy is related to chemical change because you need chemical energy, or activation energy, to start a chemical change/reaction.

Hope this helps!

What is the difference between cell and cellmembrane​
lisov135 [29]

Answer:

So, a cell, in easiest terms, is "the building blocks of life". Without cells, humans, plants, animals, and anything else that has a cell would not be able to survive. Cells are extremely important to our bodies. Whereas a Cell Membrane is an organelle inside a cell. The Cell Membrane's job is to provide protection for the cell, as well as deciding which substances can enter and exit the cell.

I hope this helps!

How many grams of sulfur are needed to react completely with 246 g of mercury to form hgs?
iren [92.7K]

The reaction between mercury (Hg) and sulfur (S) to form HgS is:

Hg + S ------------- HgS

Therefore: 1 mole of Hg reacts with 1 mole of S to form 1 mole of HgS

The given mass of Hg = 246 g

Atomic mass of Hg = 200.59 g/mol

# moles of Hg = 246 g/ 200.59 gmol-1 = 1.226 moles

Based on the reaction stoichiometry,

# moles of S that would react = 1.226 moles

Atomic mass of S = 32 g/mol

Therefore, mass of S = 1.226 moles*32 g/mole = 39.23 g

39.2 g of sulfur would be needed to react completely with 246 g of Hg to produce HgS
