Writing and Balancing chemical equations?
Answer Questions The average lecture hall has dimensions of approximately Is using a balance to measure mass considered an experiment? How and why do: What is the Purest form of carbon?
A liquid has a volume of 7. What is its volume in mL? Then start solving the system of equations to get the following values: Not Helpful Helpful Read the steps carefully and keep a notebook and a pen with you during reading the steps. After reading the steps, write each step one by one "in your own words", noting it in your notebook one by one and using the picture to enhance your comprehension. This equation is already balanced when using the first method Traditional balance in the article.
First multiply NaCl by 2, since you have 2 Na on the reactant side. Then, since there are now 2 Cl in the product side, multiply HCl by 2. Not Helpful 21 Helpful What causes the color of copper sulphate to change when an iron nail is dipped into it? When iron Fe and copper sulphate CuSO4 solution react, they undergo a single displacement reaction, also known as a substitution reaction, to form solid copper Cu and aqueous iron sulphate FeSO4.
The iron can be solid or aqueous but the copper sulphate must be aqueous in order to facilitate the reaction. Multiply the left side by 2 to get 2 Oxygen. Then multiply Hg on the right by 2. Not Helpful 89 Helpful On step 7 it says you now have 6 oxygen atoms in the carbon dioxide molecule do I times the 3 to get 6?
You multiply the subscript by the number that was put out in front. So CO2 has one carbon and two oxygen atoms pretend the 2 is subscript , while 3 CO2 has 3 carbon and six oxygen atoms. You always multiply the number in front by the subscript and if there is none, it means that the subscript is equal to 1. It is a balanced equation. According to the law of conservation of mass, the amount of P will be the same on both sides.
So the amount of P as a reactant a , will be the same as the amount of the product of P c. Magnesium will react with diluted nitric acid to produce magnesium nitrate and hydrogen gas. Answer this question Flag as Include your email address to get a message when this question is answered.
Already answered Not a question Bad question Other. Did this summary help you? If all of your coefficients can be divided by the same number, do so to get the simplest result. Warnings To get rid of fractions, multiply the entire equation both the left and right sides by the number in the denominator of your fraction.
During the balancing process, you may use fractions to assist you, but the equation is not balanced as long as there are still coefficients using fractions. Never use fractions as coefficients in a chemical equation--you never make half of a molecule or half of an atom in a chemical reaction.
