Answer:
Its either B or D. I personally would go with B
Explanation:
Answer:
Mass of solution = 2 g
Explanation:
Given data:
Mass of CuSO₄ = 0.20 g
Percent by mass = 10%
Mass of solution needed = ?
Solution:
Formula:
Percent by mass = mass of solute / mass of solution × 100
Now we will put the values.
10 = 0.20 g/ mass of solution × 100
10/ 100 = 0.20 g/ mass of solution
0.1 = 0.20 g/ mass of solution
Mass of solution = 0.20 g/ 0.1
Mass of solution = 2 g
Temperature
surface area
reactant concentration
D.
Gastropods live in every conceivable habitat
Answer:
if you mix any halogen with any alkali then ionic salt will be formed and also this will cause an exothermic reaction in which heat is getting released
