Answer:
When a solid reaches the temperature of its melting point, it can become a liquid. For water, the temperature needs to be a little over zero degrees Celsius (0oC) for you to melt.
Cause potassium comes from strong base and acetate comes from weak acid, when they disociate potassium is stronger base or weaker conjugated acid than acetate is cause acetate is weaker acid or stronger conjugated base... i hope you can get it from this what i wrote
Answer:
The presence of nitrogen in the organic compound is detected by fusing organic compounds with sodium metal to give sodium cyanide (NaCN) soluble in water. This is converted into sodium ferrocyanide by the addition of sufficient quantities of ferrous sulphate.
Explanation:
It is what I found online.

Answer:HCl</h2>
Explanation:
![\text{number of moles}=\frac{\text{given mass}}{\text{molar mass}}](https://tex.z-dn.net/?f=%5Ctext%7Bnumber%20of%20moles%7D%3D%5Cfrac%7B%5Ctext%7Bgiven%20mass%7D%7D%7B%5Ctext%7Bmolar%20mass%7D%7D)
For ![NH_{3},](https://tex.z-dn.net/?f=NH_%7B3%7D%2C)
![\text{given mass}=3g](https://tex.z-dn.net/?f=%5Ctext%7Bgiven%20mass%7D%3D3g)
![\text{molar mass}=14+3=17g](https://tex.z-dn.net/?f=%5Ctext%7Bmolar%20mass%7D%3D14%2B3%3D17g)
![n_{NH_{3}}=\frac{3}{17}=0.176](https://tex.z-dn.net/?f=n_%7BNH_%7B3%7D%7D%3D%5Cfrac%7B3%7D%7B17%7D%3D0.176)
For ![HCl,](https://tex.z-dn.net/?f=HCl%2C)
![\text{given mass}=5g](https://tex.z-dn.net/?f=%5Ctext%7Bgiven%20mass%7D%3D5g)
![\text{molar mass}=1+35.5=36.5g](https://tex.z-dn.net/?f=%5Ctext%7Bmolar%20mass%7D%3D1%2B35.5%3D36.5g)
![n_{HCl}=\frac{5}{36.5}=0.136](https://tex.z-dn.net/?f=n_%7BHCl%7D%3D%5Cfrac%7B5%7D%7B36.5%7D%3D0.136)
The reaction between
and
is
→![NH_{4}Cl](https://tex.z-dn.net/?f=NH_%7B4%7DCl)
So,one mole of
requires one mole of ![HCl](https://tex.z-dn.net/?f=HCl)
moles of
requires
moles of ![HCl](https://tex.z-dn.net/?f=HCl)
But there are only
moles of
available.
will be consumed first.
So,
is the limiting reagent.
