Answer:

31.36 L of chlorine gas will react with 56 g of calcium.

Explanation:

Ca + Cl_2\rightarrow CaCl_2

Mass of calcium = 56 g

Moles of calcium gas = \frac{56 g}{40 g/mol}=1.4 moles

According to reaction, 1 mole of calcium react with 1 mole of chlorine gas.

Then 1.4 mol of calcium wiull react with :

\frac{1}{1}\times 1.4 = 1.4 mol chlorine gas

At standard temperature and pressure. 1 mol of gas occupies 22.4 L of volume.

Then 4.1 moles of chlorine gas will occupy :

22.4 L\tmes 4.1 =31.36 L

31.36 L of chlorine gas will react with 56 g of calcium.

The balanced chemical reaction is:

<span>Ca + Cl2 =  CaCl2
</span>
We are given the amount of calcium metal to be used for this reaction. This will be the starting point for the calculations.

56 g Ca ( 1 mol Ca / 40.08 g Ca) (1 mol Cl2 / 1 mol Ca) ( 22.414 L Cl2 / 1 mol Cl2 ) = 31.32 L Cl2 gas produced from the reaction

Answer:

a) Platinum > Beryllium > Aluminum > Magnesium > Potassium > Cesium

b) Cesium > Potassium > Magnesium > Aluminum > Beryllium > Platinum

c) Cesium > Potassium

Explanation:

We must recall that the frequency of an electromagnetic wave is directly proportional to its energy. Hence as the work function of the metal increases, the minimum frequency required for emission of electrons occur increases accordingly.

Similarly, the maximum wavelength required for electron emission to occur varies inversely as the work function of the metal hence the answer provided.

Lastly, only caesium and potassium has work function less than the energy of the incident photon hence only these two metals experience electron emission with the kinetic energy of electrons emitted from caesium greater than that emitted from potassium.

If your sample contained a volatile impurity, what value would be in error
weeeeeb [17]
A volatile impurity, is an impurity that evaporates quickly, so, if you were to conduct an experiment on a substance with this type of impurity, the evaporation point, and the mass of the substance at high temperatures would be in error.

How many moles are in 50 grams of cobalt? <br><br> help asapp
sammy [17]

hey there!

atomic mass cobalt = 58.9332 amu

therefore:

1 mol Co ------------ 58.9332 g

moles ------------ 50 g

moles = 50 x 1 / 58.9332

moles  = 50 / 58.9332

 = 0.8484 moles of Co

Hope this helps!
