Question

this easily compressible state of matter has very little interaction amongst * 1 point other molecules in the same state
solid
liquid
gas
is the shown reaction balanced? * 1 point
combustion chemical reaction
ch₄ + 2o₂ → co₂ + 2h₂o

Explanation:

Step1: Recall states of matter properties

Solids have closely - packed molecules with strong intermolecular forces and are not easily compressible. Liquids have stronger intermolecular forces compared to gases and are less compressible. Gases have widely spaced molecules with very little interaction between them and are easily compressible. So the answer to the first question is Gas.

Step2: Check atom conservation in reaction

For the reaction $CH_4 + 2O_2
ightarrow CO_2+2H_2O$, on the left - hand side: 1 carbon atom, 4 hydrogen atoms ($1\times4$ from $CH_4$), and 4 oxygen atoms ($2\times2$ from $2O_2$). On the right - hand side: 1 carbon atom in $CO_2$, 4 hydrogen atoms ($2\times2$ from $2H_2O$), and 4 oxygen atoms (2 in $CO_2$ and $2\times1$ in $2H_2O$). Since the number of each type of atom is the same on both sides, the reaction is balanced.

Answer:

1. C. Gas
2. Yes
