Salt is usually formed during neutralization reactions,
that is the reaction of an acid and a base. This is illustrated as follows:
<span>HX + YOH --> XY
+ H2O</span>
where XY is the salt
From the given choices, the only pair of acid and base is:
<span>Vinegar and antacids</span>
Answer: 0.67 moles of ![N_2H_4](https://tex.z-dn.net/?f=N_2H_4)
Explanation:
According to avogadro's law, 1 mole of every substance occupies 22.4 L at STP and contains avogadro's number
of particles.
To calculate the moles, we use the equation:
![\text{Number of moles of nitrogen}=\frac{\text{Given mass}}{\text {Molar mass}}=\frac{28.3}{28.02}=1mole](https://tex.z-dn.net/?f=%5Ctext%7BNumber%20of%20moles%20of%20nitrogen%7D%3D%5Cfrac%7B%5Ctext%7BGiven%20mass%7D%7D%7B%5Ctext%20%7BMolar%20mass%7D%7D%3D%5Cfrac%7B28.3%7D%7B28.02%7D%3D1mole)
![2N_2H_4(l)+N_2O_4(l)\rightarrow 3N_2(g)+4H_2O(g)](https://tex.z-dn.net/?f=2N_2H_4%28l%29%2BN_2O_4%28l%29%5Crightarrow%203N_2%28g%29%2B4H_2O%28g%29)
According to stoichiometry:
3 moles of
is produced by 2 moles of ![N_2H_4](https://tex.z-dn.net/?f=N_2H_4)
Thus 1 mole of
is produced by=
of ![N_2H_4](https://tex.z-dn.net/?f=N_2H_4)
Thus 0.67 moles of
are required to produce 28.3 g of
It would distract the pain in your toe. That's all I got
Answer:
15/15
Explanation:
set the numbers equal to each other side by side and subtract the first numerator(the top number) by the second one
