Chapter 6: Problem 15

If a sample of pure hydrogen gas is ignited very carefully, the hydrogen burns gently, combining with the oxygen gas of the air to form water vapor. Write the unbalanced chemical equation for this reaction.

Short Answer

Expert verified
The balanced chemical equation for the combustion of hydrogen gas with oxygen gas to form water vapor is: \[ 2H_{2} + O_{2} \rightarrow 2H_{2}O \]

Step by step solution

01

Identify the reactants and products

In this reaction, hydrogen (H2) and oxygen (O2) are the reactants, and the product is water vapor (H2O). Step 2: Writing the unbalanced equation
02

Write the chemical symbols for the reactants and products

Now that we know the reactants and products, we can write the unbalanced chemical equation: \[ H_{2} + O_{2} \rightarrow H_{2}O \] Step 3: Balancing the chemical equation
03

Adjust the coefficients to balance the equation

Currently, the equation is not balanced because there are two oxygen atoms on the left side of the equation and only one on the right side. To balance the equation, we can adjust the coefficients. Place a 2 in front of H2O: \[ H_{2} + O_{2} \rightarrow 2H_{2}O \] Now we have 2 hydrogen atoms on the left and 4 on the right. To balance the hydrogen atoms, place a 2 in front of H2: \[ 2H_{2} + O_{2} \rightarrow 2H_{2}O \] The balanced equation should look like this: \[ 2H_{2} + O_{2} \rightarrow 2H_{2}O \]

Your family may have a "gas grill" for outdoor cooking. Gas grills typically use bottled propane gas \(\left(\mathrm{C}_{3} \mathrm{H}_{8}\right),\) which burns in air (oxygen) to produce carbon dioxide gas and water vapor. Write the unbalanced chemical equation for this process. Gas grills should never be used indoors, however, because if the supply of oxygen is restricted, the products of the reaction tend to be water vapor and toxic carbon monoxide, instead of nontoxic carbon dioxide. Write the unbalanced chemical equation for this process.

When iron wire is heated in the presence of sulfur, the iron soon begins to glow, and a chunky, blue black mass of iron(II) sulfide is formed. Write the unbalanced chemical equation for this reaction.

When small amounts of acetylene gas are needed, a common process is to react calcium carbide with water. Acetylene gas is evolved rapidly from this combination even at room temperature, leaving a residue of calcium hydroxide. Write the balanced chemical equation for this process.

When home-made biscuits are baked, baking powder is added to make the biscuits "rise." What evidence suggests that baking powder works through means of a chemical reaction?

We write chemical equations to describe a reaction in "shorthand." Where are the reactants found in an equation? (left/right) Where are the products? (left/right) What does the arrow ( \(\rightarrow\) ) signify?
