Answer:
The answer to your question is 4 M
Explanation:
Data
NaCl 2 moles
Volume = 0.5 l
Molarity = M
Process
1.- Write the formula of Molarity
2.- Substitution
3.- Simplification and result
Molarity = 4 M
Answer:
D. AX + BY -> AY + BX
Explanation:
Double replacement:
It is the reaction in which two compound exchange their ions and form new compounds.
AB + CD → AC +BD
So from given list of reactions option D is correct while others are incorrect.
Other examples:
The reaction between sodium chloride and silver nitrate is double displacement reaction.
NaCl + AgNO₃ → AgCl + NaNO₃
The anion and cations of both reactants exchange. The anion of sodium chloride (Cl⁻) combine with cation of silver nitrate (Ag⁺) and form AgCl. While Anion of silver nitrate combine with cation of sodium chloride and form sodium nitrate.
Answer:
Car B has more inertia than Car A
Explanation:
Given that,
Mass of car A = 1500 kg
Mass of car B = 2000 kg
Inertia is directly proportional to the mass of an object. Inertia is the measure of the mass of an object.
In this case, the mass of car B is more than that of car A, it means the inertia of car B is more than that of car A.
Hence, the correct option is (c) "Car B has more inertia than Car A".
Answer:
