Consider a hypothetical reaction in which A and B are reactants and C and D are products. If 19 g of A completely reacts with 26 g of B to produce 17 g of C, how many grams of D will be produced?
1 answer:
Given reaction:
A + B ------ C + D
mass of A = 19 grams
Mass of B = 26 grams
Mass of C = 17 grams
To determine: The mass of D
Explanation:
As per the law of conservation of mass, in any chemical reaction the sum of masses of the reactants and products must remain unchanged.
Sum of masses of reactants = Sum of masses of products
19 g + 26 g = 17 g + D
Mass of D = (19+26) - 17 = 28 g

Answer:
Products
Explanation:
In a chemical reaction, the atoms and molecules produced by the reaction are called products
Answer:
the amount of products and reactants is constant
Answer:
Covalent compounds have weak forces of attraction between the binding molecules. Thus less energy is required to break the force of bonding. Therefore covalent compounds have low melting and boiling point.
