Answer:
The weight of the object on earth =441N
Weight of the object on moon = 72N
Explanation:
Weight of a body is the product of its mass and acceleration due to gravity. Acceleration due to gravity varies between planetary bodies. The acceleration due to gravity on earth is 9.8 m/s² while on moon is 1.6m/s² and it goes different for others too.
Weight = Mass * acceleration due to gravity
Weight(e) = weight on earth
Weight (m) = weight on moon
Weight(e) = 45 * 9.8 = 441N
Weight (m) = 45 * 1.6 = 72N
Weight of a body is measured in a unit called Newton(N)
Answer:
c. the soluble compound exists as dissolved ions in a solution while insoluble compound forms as a precipitated.
Explanation:
Let's consider an example of a double displacement reaction that produces a soluble compound and an insoluble one.
BaCl₂(aq) + Na₂SO₄(aq) ⇒ NaCl(aq) + BaSO₄(s)↓
NaCl is a soluble compound so it is dissolved in the solution. It is also an electrolyte so it ionizes in water according to the following equation:
NaCl(aq) ⇒ Na⁺(aq) + Cl⁻(aq)
BaSO₄ is insoluble so it remains as a precipitate.
