the total mass is 187g. The total mass of the reactant is always equal to total mass of the products.
explanation:
as per the given details, the reactant involved in the reaction are 37g of magnesium and 150g of sulfuric acid . the total of the reactant is 187g.
Answer:
Explanation:
Combination Reaction: is a reaction that occurs when two or more reactants combine to form a single new products. The reactants can either be Elements or Compounds. It does not require heat during the reaction.
A + B ---------> C
C (s) + O2 (g) ----------> CO2 (g)
CaO (s) + H2O (l) ---------> Ca(OH)2 (s)
In this reaction, energy is released.
Decomposition Reaction: is a reaction that occurs when a a single reactant is broken down to form two or more products. Application of heat is usually required in this type of reaction.
Δ
AB ---------> C + D
Δ
CaCO3 (s) --------> CaO (s) + CO2 (g)
In this reaction, energy is absorbed.
A chemical separation is a separation method that involves change in the chemical composition of one of the solutions that are to be separated in order to a new physical properties of one part reached leaving the rest alone.
For example, When we add a chemical to the solution that will precipitate only one part of the solution leaving the rest.
A physical separation is a separation in which solutions are separated on the basis of their physical properties.
For example, If we use physical separation method in separating two oils with different specific volumes then these two oils are separated on the basis of their settling.
Answer:
C. Conduction requires objects to have direct physical contact; convection does not.
Explanation:
Conduction is used in cooking. You have to put the pot on the burner to cook the food. Otherwise, the air will cool it and the food will not cook because it's not getting the pot hot.
Convection moves heat through electromagnetic waves, kinda like the sun warming the Earth.
I hoped this helped and please tell me if you have any questions. (And you can choose if you want an explanation or not!) Have an awesome day!
