What if the total mass of the product in a chemical reaction is 14grams what must the combined masses of the reactants be?
The mass of reactants is equal to the mass of products.
If the total mass of the product in this chemical reaction is 14g what must the combined masses of the reactants be?
4
What must happen in order for the law of conservation of matter to be followed during the chemical process?
The mass of reactants must be equal to the mass of products.
what are characteristics of chemical equation?
All chemical reactions have a common structure. It must have reactants, that are the substances that you have at the beginning, and the product that are the new substances you get at the end.
What are the characteristics of chemical equations?
All chemical reactions have a common structure. It must have reactants, that are the substances that you have at the beginning, and the product that are the new substances you get at the end.
What must happen for reactants to be changed into product?
in order for reactants to be changed into products, there needs to be a chemical change.
What has to happen for a chemical change to happen?
At least 2 of the reactants must change their chemical formula.
What if the total mass of the product in a chemical reaction is 14grams what must the combined masses of the reactants be?
The mass of reactants is equal to the mass of products.
In a chemical reaction the reaction must do what?
The reaction must change the chemical nature of reactants.
If the total mass of the product in this chemical reaction is 14g what must the combined masses of the reactants be?
4
What must happen in order for the law of conservation of matter to be followed during the chemical process?
The mass of reactants must be equal to the mass of products.
What 3 things need to happen in order for a chemical reaction to occur?
This isn't answerable without knowing what the chemical reaction is. Some reactions are very easy to initiate - alkali metals and halogens will react with little to no prodding. Others require intermediate reactions.
Why is it wrong to change subcripts when balancing chemical equation?
When you are balancing known reactants and known products which is always the case when you are asked to "balance" a chemical equation you must not change the subscripts as that changes the reactants or the products to a different chemical compound.
The correct terms for the two sides of a chemical equation?
given the law of conservation of mass, we now know that the mass of the reactants must equal the mass of the product.
what are characteristics of chemical equation?
All chemical reactions have a common structure. It must have reactants, that are the substances that you have at the beginning, and the product that are the new substances you get at the end.
How does mass of the reactants compare with the mass of the products?
The Law of Conservation of Mass applies. The total mass of all the reactants MUST equal the total mass of all the products, The individual comoounds may vary. e,g, A + B = C + D 25 g (A) + 30g (B) = 55 g of reactants. So the total mass of the products MUST equal 55 g. However, product (C) may have a mass of 40g , then product (D) MUST equal 15 g Hence 40 g + 15 g = 55 g,
What must happen for cultural change to occur?
