QuestionPredi 3: Molar mass, Conversions, Conservation of Mass, Balancing Equations, 24) In the equation: $\mathrm{H}_{2}(\mathrm{~g})+\mathrm{O}_{2}(\mathrm{~g}) \rightarrow \mathrm{H}_{2} \mathrm{O}$ (I) what state of matter is $\mathrm{H}_{2}$ ? What tate of matter is $\mathrm{H}_{2} \mathrm{O}$ ?

STEP 1

What is this asking? This problem is asking us to identify the states of matter of hydrogen gas ( $H_2$ ) and water ( $H_2O$ ) in a chemical reaction. Watch out! Don't confuse the abbreviations for states of matter! $g$ means gas, $l$ means liquid, $s$ means solid, and $aq$ means aqueous (dissolved in water).

STEP 2

1. Identify the state of $H_2$ .
2. Identify the state of $H_2O$ .

STEP 3

Look at the equation: $H_2(g) + O_2(g) \rightarrow H_2O(l)$ .
See that little $(g)$ after the $H_2$ ?
That tells us something super important!

STEP 4

The $(g)$ stands for gaseous, which means $H_2$ is in the gas state!
Woohoo!

STEP 5

Now, let's look at the equation again: $H_2(g) + O_2(g) \rightarrow H_2O(l)$ .
This time, we're focusing on the $H_2O$ .
Notice that it's followed by an $(l)$ .

STEP 6

The $(l)$ stands for liquid, meaning $H_2O$ is in the liquid state!
So cool!

STEP 7

In the given equation, $H_2$ is in the gaseous state, and $H_2O$ is in the liquid state.

STEP 2

1. Identify the state of H2H_2H2​.2. Identify the state of H2OH_2OH2​O.

STEP 3

Look at the equation: H2(g)+O2(g)→H2O(l)H_2(g) + O_2(g) \rightarrow H_2O(l)H2​(g)+O2​(g)→H2​O(l).See that little (g)(g)(g) after the H2H_2H2​?That tells us something super important!

STEP 4

The (g)(g)(g) stands for **gaseous**, which means H2H_2H2​ is in the **gas** state!Woohoo!

STEP 5

Now, let's look at the equation again: H2(g)+O2(g)→H2O(l)H_2(g) + O_2(g) \rightarrow H_2O(l)H2​(g)+O2​(g)→H2​O(l).This time, we're focusing on the H2OH_2OH2​O.Notice that it's followed by an (l)(l)(l).

STEP 6

The (l)(l)(l) stands for **liquid**, meaning H2OH_2OH2​O is in the **liquid** state!So cool!

STEP 7

In the given equation, H2H_2H2​ is in the **gaseous** state, and H2OH_2OH2​O is in the **liquid** state.
