Answer: 0.771 g of
will be produced
Explanation:
To calculate the moles :
The balanced chemical reaction is:
According to stoichiometry :
2 moles of
produce = 3 moles of
Thus 0.257 moles of
will produce=
of
Mass of
Thus 0.771 g of
will be produced
Answer:
Anions. Some atoms have nearly eight electrons in their valence shell and can gain additional valence electrons until they have an octet. When these atoms gain electrons, they acquire a negative charge because they now possess more electrons than protons. Negatively charged ions are called anions.
Answer:
Theoretical yield of hydrogen is 1.11 g
Explanation:
Balanced equation, ![Mg+2HCl\rightarrow MgCl_{2}+H_{2}](https://tex.z-dn.net/?f=Mg%2B2HCl%5Crightarrow%20MgCl_%7B2%7D%2BH_%7B2%7D)
As Mg remain present in excess therefore HCl is the limiting reagent.
According to balanced equation, 2 moles of HCl produce 1 mol of
.
Molar mass of HCl = 36.46 g/mol
So, 40.0 g of HCl =
of HCl = 1.10 moles of HCl
Hence, theoretically, number of moles of
are produced from 1.10 moles of HCl = ![(\frac{1}{2}\times 1.10)moles=0.550moles](https://tex.z-dn.net/?f=%28%5Cfrac%7B1%7D%7B2%7D%5Ctimes%201.10%29moles%3D0.550moles)
Molar mass of
= 2.016 g/mol
So, theoretical yield of
= ![(0.550\times 2.016)g=1.11g](https://tex.z-dn.net/?f=%280.550%5Ctimes%202.016%29g%3D1.11g)
Capsaicin is the chemical in the peppers, and then milk reverses it by using casein (A fat loving compound) to bond to the capsaicin and wash it away. Hope this helps!
Answer:
Soap decreases surface tension by changing the way water behaves on the surface. Hard and soft water react differently when soap is added to them.
