Answer: Rotary, Oscillating, Reciprocating.
Oscillating creates pressure on the walls of the container
Explanation: Molecules are colliding with each other and with the wall of the inside of the container bouncing back and forth in oscillating motion. As they collide, they exert force and fill the container. Hence the Oscillating motion creates pressure from swinging of molecules from wall to wall.
Answer:
200–300 mg/day ascorbic acid from vitamin C-rich foods [10]. ... as high as 3 g ascorbic acid taken every 4 hours would produce peak ... individuals should ensure that they meet the RDA for vitamin C [4,8].
Explanation:
<em>The Molecular Mass for Phosphorus is 31 grames / mole.
So, 31g. P.....................1 mole
2.3g. P ..........................x mole

Answer:
Ni^2+(aq) + CO3^2-(aq) -----> NiCO3(s)
Explanation:
First let us put down the molecular equation of the reaction
Na2CO3(aq) + Ni(NO3)2(aq)----> 2NaNO3(aq) +NiCO3(s)
Hence ionically, we will have the reaction as;
Ni^2+(aq) + CO3^2-(aq) -----> NiCO3(s)
The ionic equation usually indicate the ions that actually take part in the reaction. They often lead to the formation of the solid product or precipitate.
The order ions that are no shown in the ionic reaction equation are called spectator ions.
Hence, the reaction shown in the answer is the ionic reaction equation for the mixing of nickel II nitrate and sodium carbonate.
