mafiozo [28]3 years ago
6 0

Answer:

Pb oxidation number is +2

C in CH4 is -4. H is +1. 4H + 1C = 0. ; 4(+1) + C = 0 ; C = -4

O is usually -2. 3O = 3(-2) = -6. ; 2Fe =. +6 ; each Fe is +3

2Ag = +2 since O = -2 ; each Ag = +1

Calculate the number of atoms in 0.316 mol of phosphorus
Nikitich [7]

Answer:

\large \boxed {7.61 \times 10^{23}\text{ atoms}}

Explanation:

1. Molecules of P₄

The molecular formula of phosphorus is P₄.

\text{Molecules of P}_{4} = \text{0.316 mol P}_{4} \, \times \dfrac{ 6.022  \times 10^{23}\text{ molecules P}_{4}}{\text{1 mol P}_{4}} = 1.90 \times 10^{23}\text{ molecules P}_{4}

2. Atoms of P

One molecule of phosphorus contains four P atoms.

\text{Atoms of P} = 1.90 \times 10^{23}\text{ molecules P}_{4} \times \dfrac{\text{4 atoms P}}{\text{1 molecule P}_{4}}\\\\= \large \boxed{\mathbf{7.61 \times 10^{23}}\textbf{ atoms P}}

How can you increase the boiling point of water?
pshichka [43]

Answer:

Explanation:

Adding any solute to water will increase the boiling temperature, as it reduces the vapour pressure, meaning a slightly higher temperature is required in order for the vapour pressure to become equal to atmospheric pressure and boil the water. Essentially, adding any non-volatile solute (such as salt, baking soda or sugar) to a liquid causes a decrease in the liquid's vapour pressure.

Balance <br><br> _Mg + _HCL = _MgCl2 + H2
Pavel [41]
_Mg + _HCL = _MgCl2 + H2
Separate the terms on each side: 

_Mg + _HCl = _MgCl2 + H2

Mg- 1                 Mg-1
               
H-1                    H-2

Cl-1                    Cl-2

Mg is balanced on both sides so move on to the next (put a 1 in the space). 

1Mg

There are two H's and two Cl's on the results side, so to balance the equation put a 2 as a coefficient for HCl and it'll all balance out.

2HCl

Balamced equation will be: 

 1Mg + 2HCL = 1MgCl2 + H2
