Answer:
N₂(g) + 4H⁺(aq) + 4e⁻ → N₂H₄(aq)
Explanation:
The half reaction for the reaction for the reduction of gaseous nitrogen to aqueous hydrazine is;
N₂(g) → N₂H₄(aq)
The balancing the atoms in the half reaction. Hydrogen atom is balanced by adding hydrogen ions (H⁺)
We have;
N₂(g) + 4H⁺(aq) → N₂H₄(aq)
Then we balance the charge on both sides by adding electrons where the positive charge is greater;
we have;
N₂(g) + 4H⁺(aq) + 4e⁻ → N₂H₄(aq)
Answer:
b. aluminum
Explanation:
The specific heat capacity is defined as the amount of heat required to raise the temperature of 1g of a material in 1°C.
Thus, the sample with the higher specific heat capacity is the sample that will require more energy to increase its temperature in 1°C, suffering the smallest change in temperature.
Thus, is the aluminium with 0.900J/gK the element that is most likely to undergo the smallest change in temperature:
<h3>b. aluminum
</h3>
The answer would be the ability to be tested. If a hypothesis is testable, it would of course lead you to test it. Which, by definition is a new experiment.
The land is warm during the day. For example, if you near a sea early in the morning, you could see how cold, cool the place is.
