Answer:
D.) They often form hydroxide ions.
Explanation:
They generate hydroxide ions in water. they are soapy to touch and bitter in taste. they conduct electricity.
(all bases have hydroxide ions)
To find out the maximum amount of N2H4 that can be prepared, we must determine which reactant is the controlling factor first. Controlling factor is the reactant that is converted completely during the reaction. Therefore we must first find out the moles of the each reactant (mass/molar mass).
Moles of N2 = 14 g/(28 g/mole) = 0.5 mole
Moles of H2 = 28 g/(2 g/mole) = 14 mole
Because the reaction ratio between N2 and H2 is 1:2, for a complete reaction of 0.5 moles N2, 1 mole H2 is needed. Clearly there are excess amount H2 present. So N2 is the controlling factor.
The ratio between N2 and N2H4 is 1:1, so the maximum moles of N2H4 generated from the reaction is also 0.5 mole. The maximum mass of N2H4 is 0.5 mole * 32 g/mole = 16 g.

Hey there!
In a synthesis reaction, two or more substances combine to form one substance.
An example of this type of reaction is the synthesis of water:
2H₂ + O₂ = 2H₂O
Keep in mind that only one product is formed.
Hope this helps!
Answer:
The Weight
Explanation:
Even know it has the same volume does not mean it has the same mass and weighs the same with the items inside the box. Most likely, that the Items inside the box are heavier then the first box Max moved.
