Answer:

Mass of chlorine = 47.22 g

Explanation:

Given data:

Mass of sodium = 30.5 g

Mass of chlorine= ?

Solution:

Chemical equation:

 2Na + Cl₂      →      2NaCl  

Number of moles of Na:

Number of moles = mass/molar mass

Number of moles = 30.5g/ 23 g/mol

Number of moles = 1.33 mol

Now we will compare the moles of Cl ₂ with Na from balance chemical equation.

                    Na            :              Cl ₂

                     2              :               1

                     1.33          :            1/2×1.33 = 0.665 mol

Mass of chlorine gas:

Mass = number of moles × molar mass

Mass = 0.665 mol × 71 g/mol

Mass = 47.22 g

If 14.5 kJ of heat were added to 485 g of liquid water, How much would its temperature increase?
olga55 [171]

<u>Answer:</u> The increase in temperature is 7.14°C

<u>Explanation:</u>

To calculate the change in temperature, we use the equation:

q=mc\Delta T

where,

q = heat absorbed = 14.5 kJ = 14500 J    (Conversion factor: 1 kJ = 1000 J)

m = mass of water = 485 g g

c = specific heat capacity of water = 4.184 J/g.°C

\Delta T = change in temperature = ?

Putting values in above equation, we get:

14500J=485g\times 4.184J/g.^oC\times \Delta T\\\\\Delta T=7.14^oC

Hence, the increase in temperature is 7.14°C

Identify the two types of radiation shown in the figure below. Explain your reasoning.
saul85 [17]

Answer:- \gamma and \alpha radiation.

Explanations:-  Alpha particle is helium nucleus with two protons and two neutrons and so it has +2 charge where as gamma is a form of light, so these are rays and not particles. Since these are rays, the charges for gamma rays is zero means they are neutral.

When alpha particles are passed through electromagnetic field they are repelled by the positive plate and attracted by the negative plate as there is an attraction between opposite charges. So, the line we see towards positive plat is representing an alpha particle radiation.

Since gamma rays are neutral, they are not deflected in electromagnetic field and go straight. So, the other line in the diagram is representing gamma rays radiation.

Give two reasons why the crude product in most reactions is not pure.
Ostrovityanka [42]

Answer:

1) the product may be contaminated by the solvent

2) side reactions may yield unwanted products

3) some reactants may be present in the product if the reaction was incomplete

Explanation:

It is common in chemistry to pass reaction products through purification processes. This is done for a number of reasons.

First of all, some solvents molecules may be attached to the reaction product. These solvent particles must be separated in order to obtain a pure product.

Secondly, some side reactions also yield products that are isolated along with the desired products and these must be separated accordingly.

Finally, some chemical reactions do not go on to completion. This implies that some reactants may still be isolated alongside the product at the end of the reaction.
