Why can't calcium hydroxide be written caoh2?

Chemistry

Alexxandr [17]3 years ago

I'm assuming you mean without parenthesis and that's because if there are no parenthesis, then it looks like there is one Calcium, one Oxygen, and two Hydrogen instead of one Calcium and two Hydroxide like Ca(OH)2.

Convert 99 moles of CO2 to atoms
lorasvet [3.4K]

Answer:

              1.78 × 10²⁶ Atoms

Explanation:

Relation between number of molecules and moles is,

No. of Molecules = Moles × 6.022 × 10²³ Molecules/mol

No. of Molecules = 99 mol × 6.022 × 10²³ Molecules/mol

No. of Molecules = 5.96 × 10²⁵ Molecules

Also, In CO₂ Molecule there are 3 atoms.

So,

No. of atoms = 5.96 × 10²⁵ Molecules × 3

No. of atoms = 1.78 × 10²⁶ Atoms

katovenus [111]

Answer:

Mass of 205 mL of the liquid is 164 g

Explanation:

We know, density=\frac{mass}{volume}

Here density of liquid is 0.798 g/mL and volume of liquid is 205 mL

So, mass of liquid = density\times volume

                              = (0.798 g/mL)\times (205 mL)

                              = 164 g

hence mass of 205 mL of the liquid is 164 g.

What is nuclear fusion what role does it play in the sun
GalinKa [24]

Answer:

Nuclear fusion is when two atomic nuclei combine and form one nucleus. Nuclear fusion generates all of the Sun's energy. Inward pulling by the Sun's gravity is counteracted by outward pushing by the Sun's nuclear fusion; this balance keeps the sun from collapsing or exploding.
