Concept explainers
Interpretation: By using the formation of water from hydrogen and oxygen, the terms chemical reaction, reactant and product are to be explained.
Concept Introduction:
Chemical reaction is a process in which one substance breaks into two or more substances react with each other in the presence of reagent or catalyst under the appropriate experimental conditions leading to the formation of one or more substances. During
The substances undergoing a reaction is known as reactants, whereas the substances obtained from chemical reaction are called as products.
To Explain: The terms chemical reaction, reactant and product using the formation of water from hydrogen and oxygen.
Explanation of Solution
Formation of water takes place by the combination of hydrogen and oxygen.
- Chemical reaction is a combination of two or more substance to give one or more substance as product. Here, in the formation of water, hydrogen and oxygen combines with each other to give water.
- Hydrogen and oxygen undergoing the reaction are called as reactants.
- Water obtained from the reaction of hydrogen and oxygen is called as product.
By using the formation of water from hydrogen and oxygen, the terms chemical reaction, reactant and product are explained.

- Many cereals are made with high moisture content so that the cereal can be formed into various shapes before it is dried. A cereal product containing 58% H2O by mass is produced at the rate of 1000. kg/h. What mass of water must be evaporated per hour if the final product contains only 20.% water?arrow_forwardhat do the coefficients of a balanced chemical equation tell us about the proportions in which atoms and molecules react on an individual (microscopic) basis?arrow_forwardMany cereals are made with high moisture content so that the cereal can be formed into various shapes before it is dried.

- Many over-the-counter antacid tablets are now formulated using calcium carbonate as the active ingredient, which enables such tablets to also be used as dietary calcium supplements. As an antacid for gastric hyperacidity, calcium carbonate reacts by combining with hydrochloric acid found in the stomach, producing a solution of calcium chloride, converting the stomach acid to water, and releasing carbon dioxide gas (which the person suffering from stomach problems may feel as a “burp”). Write the unbalanced chemical equation for this process.arrow_forward4.106 An ore sample with a mass of 670 kg contains 27.7% magnesium carbonate, MgCO3.

- 4.69 The pictures below show a molecular-scale view of a chemical reaction between H2 and CO to produce methanol, CH3OH. The box on the left represents the reactants at the instant of mixing, and the box on the right shows what is left once the reaction has gone to completion. Was there a limiting reactant in this reaction? If so, what was it? Write a balanced chemical equation for this reaction. As usual, your equation should use the smallest possible whole number coefficients for all substances.arrow_forwardConsider the chemical reaction 2 S + 3 O2 → 2 SO3.

Use your equation to help answer the following questions. a Write, in words, a description of the reaction on the particulate level. b If you were to build physical ball-and-stick models of the reactants and products, what minimum number of balls representing atoms of each element do you need if you show both reactants and products at the same time? c What if the models of the reactants from Part b were built and then rearranged to form products? How many balls would you need? d Use words to interpret the equation on the molar level. e Use the molar-level interpretation of the equation from Part d and molar masses rounded to the nearest gram to show that mass is indeed conserved in this reaction.arrow_forwardThe present average concentration (mass percent) of magnesium ions in seawater is 0.13%. A chemistry textbook estimates that if 1.00 × 108 tons Mg were taken out of the sea each year, it would take one million years for the Mg concentration to drop to 0.12%. Do sufficient calculations to either verify or refute this statement. Assume that Earth is a sphere with a diameter of 8000 mi, 67% of which is covered by oceans to a depth of 1 mi, and that no Mg is washed back into the oceans at any time.arrow_forward
