When there are 165.0grams of reactants, what is the mass of the products for that reaction?

Chemistry

vfiekz [6]2 years ago
3 0

Answer:

165.0 grams

Explanation:

The law of conservation of mass tells us that the mass of the reactants will be equal to the mass of the products. Therefore, if we begin with 165.0 grams of mass, that is how much there will be at the end in the products, even if it's in different forms.

What visual criterion is to be used to assess whether the crude reaction product is dry prior to semimicro distillation
Olenka [21]

The visual criterion which has to be assessed  is to ensure it's not oily or sticky.

<h3>What is Distillation?</h3>

This is a separation technique that involves the use selective boiling and condensation to separate a liquid mixture into different components.

In the case of Crude reaction product , it is best to ensure that it is not oily or sticky before semimicro distillation is done.

When a 21.5-g sample of LiCl was added to 195 g of water at a temperature of 20.00°C in a calorimeter, the temperature increased
Paha777 [63]

Answer:

63.09KJ/mol

Explanation:

In this case, to calculate the <u>heat of solution</u> (KJ/mol) we have to take into account the mass of water, the specific heat of the water and the temperature change, so:

m=195~g

c=4.18~J/g^{\circ}C

ΔT=39.26^{\circ}C

With this in mind, we can use the <u>equation</u>:

Q=m*c*T

If we plug the values into the equation we will have:

Q=195~g*4.18~J/g^{\circ}C*39.26^{\circ}C

Q=32000.83~J

Now, with the mass value (21.5 g) and the molar mass of LiCl (42.39g/mol) we can <u>calculate the moles of LiCl</u>:

21.5~g~LiCl\frac{1~mol~LiCl}{42.39~g~LiCl}=0.507~mol~LiCl

Now, in the heat of solution, we have <u>KJ/mol units</u>. Therefore, we have to <u>convert</u> from J to KJ:

32000.83~J\frac{1~KJ}{1000~J}=32~KJ

Finally, we can <u>divide</u> by the moles of LiCl:

\frac{32~KJ}{0.507~mol}=63.09KJ/mol

So, <u>for each mole of LiCl, we have 63.09 KJ involved in the dissolution process.</u>

I hope it helps!
