What is the specific heat of a substance if 1560 cal are required to raise the temperature of a 312-g sample by 15°C?
Oksanka [162]
The specific heat capacity  the substance is calculated  using  the below formula

Q(heat) = Mc delta T
Q =1560  cal
m(mass) 312 g
delta T (change in temperature ) = 15 c
C= specific heat capacity=?

by making c the subject of the formula 
c=Q/m delta T
= 1560  cal/ 312g x 15 c = 0.33 cal/g/c (answer B)

What mass of copper is deposited when a current of 10.0a is passed through a solution of copper(ii) nitrate for 30.6 seconds?
asambeis [7]
Data Given:

Time = t = 30.6 s

Current = I = 10 A

Faradays Constant = F = 96500

Chemical equivalent = e = 63.54/2 = 31.77 g

Amount Deposited = W = ?

Solution:
             According to Faraday's Law,

                                          W  =  I t e / F

Putting Values,
 
                            W  =  (10 A × 30.6 s × 31.77 g) ÷ 96500

                            W  =  0.100 g

Result:
           0.100 g of Cu
²⁺ is deposited.
