1 answer:

7 0

Solid- molecules vibrate in place and tightly packed
liquid-molecules fur shape of container and can slide past each other
gas-molecules also fit shape of container and have the most room

What is the correct sequence of coefficients when this equation is balanced? ___cs2(l) + ___o2(g) → ___co2(g) + ___so2(g)?

iris [78.8K]

Answer: the sequence is 1, 3, 1, 2.

Explanation:

1) Given equation: CS₂(l) + O₂(g) → CO₂(g) + SO₂(g)

2) To balance:

i) initially C is balanced: 1 atom in the left side, and 1 atom in the right sides

ii) Add coefficient 2 in front of SO₂ to have 2 atoms in each side.

That leads to: CS₂(l) + O₂(g) → CO₂(g) + 2SO₂(g)

iii) Count the O atoms; there are 2 atoms in the left, and 6 atoms in the right side. So, add a coefficient 3 in front of O₂ (in the left) and you get:

CS₂(l) + 3O₂(g) → CO₂(g) + 2SO₂(g)

4) You can verigy that now the equation is balanced:

C: 1 in the left, and 1 in the right

S: 2 in the left, and 2 in the right

O: 6 in the left, and 6 in the right.

5) So, the sequence is 1, 3, 1, 2.

Remember, when the none coefficient is shown it is because it is 1.

Which properties determines the element that an atom Is?

balandron [24]

Answer:

The answer would be C. Number of protons in the atom.

Explanation:

On the periodic table, you see the element, with a big number at top, and a small number below the element name/abbreviation.

The big number is the amount of protons of the atom, which define each atom. The smaller number represents the atomic mass of the atom.
