The process of photosynthesis is commonly written as: 6CO2 + 6H2O → C6H12O6 + 6O2. This means that the reactants, six carbon dioxide molecules and six water molecules, are converted by light energy captured by chlorophyll (implied by the arrow) into a sugar molecule and six oxygen molecules, the products.

What is a chemical reaction Class 7?
A chemical reaction involves, breaking and making of bonds between reactants to give rise to formation of new products. A chemical reaction is basically rearrangement of atoms.
What is chemical reaction Class 9?
Chemical change is brought about by addition, decomposition, exchange of atoms or molecules and the process by which chemical change occurs is called chemical reaction. If the total number of atoms in the reactants and products are same then the chemical reaction is said to be balancedchemical equation.
What are the 6 types of chemical reactions?
Six common types of chemical reactions are: synthesis, decomposition, single-displacement, double-displacement, combustion and acid-base reactions. Scientists classify them based on what happens when going from reactants to products.
How do you explain chemistry to a child?
Chemistry is the science of chemical elements and compounds. Chemistry is a branch of science that deals with chemical elements and compounds, and how these things work together. It is the study of the materials (things) that make up our bodies and everything in the world around us.

What is chemistry in short answer?
Chemistry is the branch of science that deals with the properties, composition, and structure of elements and compounds, how they can change, and the energy that is released or absorbed when they change.
What is word equation and chemical equation?
Updated on October 07, 2019. In chemistry, a word equation is a chemical reaction expressed in words rather than chemical formulas. A word equation should state the reactants (starting materials), products (ending materials), and direction of the reaction in a form that could be used to write a chemical equation.
How do you write chemical equations in Word?
- Open a new or existing Word document and click the “Insert” tab. …
- Click the “Equation” menu on the right side of the tab’s ribbon.
- Click the “Insert New Equation” option. …
- Click into the “Type equation here” box and type the formula.
Are formulas equations?
A formula is an equation that shows the relationship between two or more quantities. It would be the rule or instructions that is use to show the relationship between two or more quantities.
What is simple equation?
A simple equation refers to a mathematical equation that expresses the relationship between two expressions on both sides of the ‘equal to’ sign. This category of an equation consists of a variable, usually in the form of x or y. Solving simple equations often require rearranging it.
Where do you write equations?
- Choose Insert > Equation and choose the equation you want from the gallery.
- After you insert the equation the Equation Tools Design tab opens with symbols and structures that can be added to your equation.
What is the chemical equation for respiration?
C 6 H 12 O 6 + 6 O 2 –> 6 CO 2 + 6 H 2 O + ATP is the complete balanced chemical formula for cellular respiration.
What is the equation of photosynthesis for Class 7?
Answer: carbon dioxide + water —> glucose + oxygen + wate it can be written as 6CO2 + 6H2O —> C6H12O6 + 6O2.
What are examples of photosynthesis?
An example of photosynthesis is how plants convert sugar and energy from water, air and sunlight into energy to grow. (biology) The process by which plants and other photoautotrophs generate carbohydrates and oxygen from carbon dioxide, water, and light energy.
Which is not an example of chemical reaction?
The correct answer is Freezing of water. Freezing is a phase transition where a liquid turns into a solid when its temperature is lowered below its freezing point. Freezing of water is not a chemical change as ice when melt changes back to water showing the physical change.
What is an example of chemical change with water?
For instance, when an electric current is passed through water (H2O), it can be broken down into hydrogen and oxygen or H2 + O2. In this example, water is broken down into its two elements. The result is a chemical change because the starting and ending molecules are different.
