Answer:
0.287 mole of PCl5.
Explanation:
We'll begin by calculating the number of mole in 51g of Cl2. This is illustrated below:
Molar mass of Cl2 = 2 x 35.5 = 71g/mol
Mass of Cl2 = 51g
Number of mole of Cl2 =..?
Mole = Mass /Molar Mass
Number of mole of Cl2 = 51/71 = 0.718 mole
Next, we shall write the balanced equation for the reaction. This is given below:
P4 + 10Cl2 → 4PCl5
Finally, we determine the number of mole of PCl5 produced from the reaction as follow:
From the balanced equation above,
10 moles of Cl2 reacted to produce 4 moles of PCl5.
Therefore, 0.718 mole of Cl2 will react to produce = (0.718 x 4)/10 = 0.287 mole of PCl5.
Therefore, 0.287 mole of PCl5 is produced from the reaction.
20 grams of borax contains (20.0g) / (201 g mol -1) =0.10 mol of borax.
Therefore 0.40 mol of borax
<u>Answer:</u> The molar mass of the given unknown compound is 50.5 g/mol.
<u>Explanation:</u>
To calculate the volume of water, we use the equation given by ideal gas, which is:
or,
where,
P = pressure of sample = 1.00 atm
V = volume of sample = 2010 mL = 2.010 L (Conversion factor: 1 L = 1000 mL)
m = Given mass of unknown compound = 2.73 g
M = Molar mass of unknown compound = ? g/mol
R = Gas constant = 
T = temperature of sample = ![180^oC=[180+273]K=453K](https://tex.z-dn.net/?f=180%5EoC%3D%5B180%2B273%5DK%3D453K)
Putting values in above equation, we get:
Rounding off to 3 significant figures, we get the molar mass to be 50.5 g/mol.
Hence, the molar mass of the given unknown compound is 50.5 g/mol.
Because it’s the closest part of the earth to the sun. Basically the sun’s rays hit there more than anywhere else.
Answer:
Synthesis
Explanation:
Synthesis reaction:
It is the reaction in which two or more simple substance react to give one or more complex product.
General equation;
A + B → AB
The given reaction is synthesis reaction.
Chemical equation:
2Al + Cl₂ → 2AlCl
it is also redox reaction because oxidation reduction take place.
The oxidation state of aluminium and chlorine is zero on left side while it on right side aluminium become cation with charge of +1 and chlorine become anion with a charge of -1.
Aluminium is reducing agent while chlorine is oxidizing agent.
Oxidizing agents:
Oxidizing agents oxidize the other elements and itself gets reduced.
Reducing agents:
Reducing agents reduced the other element are it self gets oxidized.
