How do you separate Sand Potassium Nitrate and Champhor

Chemistry
1 answer:
Kitty [74]1 year ago
5 0
Heating & Cooling: The mixture is heated to get a saturated solution and it crystallises on cooling. Now since, potassium nitrate is more soluble it gets filtered out from the hot saturated solution and recrystallised in hot water and then dried. This separates the two mixtures into crystals.

Water (2230 g ) is heated until it just begins to boil. If the water absorbs 5.73×105 J of heat in the process, what was the ini
shutvik [7]

Answer: 38.5^0C

Explanation:

To calculate the initial temperature of the water:

q=m\times c\times (T_{final}-T_{initial})

where,

q = heat absorbed = 5.73\times 10^5J

c = specific heat of water = 4.18J/g^oC

m = mass of water = 2230 g

T_{final} = final temperature of water = 100^0C

T_{initial} = initial temperature of metal = ?

Now put all the given values in the above formula, we get:

5.73\times 10^5J=2230g\times 4.18J/g^oC\times (100-T_i)^0C

(100-T_i)=61.5

T_i=100-61.5)=38.5^0C

Thus, the initial temperature of the water is 38.5^0C

(b)
pentagon [3]

8%

Explanation:

In a DNA molecule the no. of Adenine bases equal to that of Thymine bases

The no. of Cytosine bases equal to that of Guamine bases.

If we take no. of Thymine bases as x and no. of Cytosine bases as y,

Adenine + Thymine + Cytosine + Guamine = 100

x + x + y+y = 100

2( x+y) = 100

x+y = 50

y=42

therefore x= 50-42 = 8%
