How is law of conservation of mass shown by a balanced chemical equation?

The law of conservation of mass states that the total mass of reactants must equal the total mass of products in a chemical reaction. A balanced chemical equation ensures this by showing an equal number of atoms of each element on both sides of the equation. This demonstrates that no atoms are lost or gained during the reaction, thus adhering to the law of conservation of mass.

What are the products in the chemical equation for photosynthesis 6 CO2 plus 6 H2O-C6H12O6 plus 6 O2?

The products of the chemical equation for photosynthesis are glucose (C6H12O6) and oxygen (O2). These are formed from carbon dioxide (CO2) and water (H2O) with the help of sunlight and chlorophyll.

What is Balanced chemical equation of pinch of baking soda added to hydrochloric acid?

The balanced chemical equation for the reaction between baking soda (sodium bicarbonate, NaHCO3) and hydrochloric acid (HCl) is:

NaHCO3 + HCl → NaCl + H2O + CO2

This reaction produces sodium chloride (table salt), water, and carbon dioxide gas.

What is the reactant(s) in the chemical equation below?

The reactants in a chemical equation are the substances that are present at the start of a reaction and are used up during the course of the reaction. If you provide the specific chemical equation, I can help you identify the reactant(s).

What is the Important of balancing?

To ensure that you have a healthy diet and life. To ensure that you have a healthy diet and life.

What is a salt give an example of an equation where salt is formed?

A salt is a compound formed when the hydrogen ion of an acid is replaced by a metal ion or an ammonium ion. For example, when hydrochloric acid (HCl) reacts with sodium hydroxide (NaOH), the salt sodium chloride (NaCl) is formed along with water: HCl + NaOH -> NaCl + H2O.

When The chemical equation blow summarizes photosynthesis. write a similar equation for cellular respiration?

Photosynthesis: 6 CO2 + 6 H2O + light energy -> C6H12O6 + 6 O2 Cellular respiration: C6H12O6 + 6 O2 -> 6 CO2 + 6 H2O + energy

What is a double replacement equation composed of?

A double replacement reaction involves the exchange of ions between two compounds. The general equation for a double replacement reaction is AB + CD -> AD + CB, where A and C are cations and B and D are anions. The products formed are two new compounds.

How Chemical equations are balanced by changing the subscripts of the molecule true or false?

False. Chemical equations are balanced by changing the coefficients in front of the chemical formulas, not the subscripts within the formulas. The number of atoms of each element must be equal on both sides of the equation to ensure that mass is conserved.

What are the names of the products in photosynthesis chemical equation?

6CO2 + 6H20 ---(sun's energy)--> 1C6H12O6 + 6O2

Carbon Dioxide + Water ---(sun's energy)--> Glucose + Oxygen

What are the correct coefficients when this chemical equation is balanced?

To provide the correct coefficients, I would need to know the specific chemical equation you are referring to. Once you provide the equation, I can help you balance it by ensuring that the number of atoms of each element is the same on both sides of the equation.

What are the steps for writing and balancing chemical equations?

  1. Write down the chemical equation using correct chemical formulas for reactants and products.
  2. Balance the number of atoms for each element on both sides of the equation by adding coefficients.
  3. Start by balancing elements that appear in only one reactant and one product.
  4. Check your work to ensure that the number of atoms for each element is the same on both sides of the equation.

What is the chemical equation for Hydrocloric acid and sodium?

The chemical equation for the reaction between hydrochloric acid (HCl) and sodium (Na) is 2HCl + 2Na -> 2NaCl + H2. This reaction produces sodium chloride (NaCl) and hydrogen gas (H2).

What may be changed in order to balance a chemical equation?

Coefficients can be adjusted to balance a chemical equation. Coefficients are placed in front of chemical formulas to ensure that there is the same number of each type of atom on both sides of the equation. The goal is to have an equal number of atoms of each element on the reactant and product sides.

What is the Chemical equation for lead carbonate and sulfuric acid?

The chemical equation for the reaction between lead carbonate (PbCO3) and sulfuric acid (H2SO4) is: PbCO3 + H2SO4 -> PbSO4 + H2O + CO2. This balanced equation shows the formation of lead sulfate (PbSO4), water (H2O), and carbon dioxide (CO2) as the products.

How do you balance the chemical equation HBr H2 plus Br2 N2O N2 plus O2 HBr H2 plus Br2 CH4 plus O2 CO2 plus H2O?

The balanced chemical equation is 2HBr + H2 + Br2 + N2O → N2 + O2 + HBr + H2 + Br2. The equation provided in your question doesn't appear to balance correctly, so I attempted to balance it based on the chemical species presented. It's essential to ensure that the number of atoms of each element is the same on both sides of the equation.

What is the balanced symbol equation for sodium astatide?

The balanced symbol equation for the formation of sodium astatide is: 2 Na + 2 At -> 2 NaAt.

Why is it always essential to balance a chemical equation?

Balancing a chemical equation is essential to ensure the law of conservation of mass is obeyed. This means that the number of atoms of each element remains the same on both sides of the equation. A balanced equation also helps in determining the correct stoichiometry of a reaction and predicting the amount of reactants needed or products formed.

What information is presented in a chemical equation?

A chemical equation presents the chemical formulas of reactants and products involved in a chemical reaction, along with the symbols and coefficients representing the amounts of each substance. It also shows the conservation of atoms (mass) and charge before and after a reaction.

What is the chemical equation for the compound sugar water?

SugarGlucose is a sugar monosaccharide (monomer): C6H12O6

Table sugar (sucrose) is C12H22O11

There are lots of sugars (monosaccharides, disaccharides, polysaccarhides). Glucose is one of the most important carbohydrates because it is used in cell respiration. All carbohydrates including sucrose are hydrolyzed in digestion - broken down to glucose. The splitting and transformation of glucose is what powers ATP production, which in turn supports cell activities.

What two things must we remember when balancing chemical equations?

When balancing chemical equations, it is important to remember to adjust coefficients (not subscripts) to ensure that the number of atoms of each element is equal on both sides of the equation. Additionally, it's crucial to balance one element at a time and to double-check the final equation to confirm that it is balanced.

2HCL plus Zn what is the result?

When hydrochloric acid (HCl) reacts with zinc (Zn), it forms zinc chloride (ZnCl2) and hydrogen gas (H2) as products. The balanced chemical equation for this reaction is: 2HCl + Zn → ZnCl2 + H2
