Which method of separation can be used for a homogeneous mixture?

1 answer:

7 0

One of the methods of separation of homogeneous mixtures is called distillation and it is based on the various boiling points of the component of mixture. Heating the mixture, the component that has the lowest boiling point will evaporate and the separation can be done. the other method is called chromatography.so the answer is d.distillation! hope this helped!

I do not think there are any. If you used -20 and 2, which would be close to 16, the sum would be 18.

For safety reasons, the manufacturer of a ladder recommends that it be used in such a way that the base of the ladder is no fart

professor190 [17]

See attached picture for better understanding of the problem. In the problem, the given values are the following:
hypotenuse = length of the ladder
adjacent = base of the ladder to base of the wall
Solving the angle x, we have the solution as below:
cos x = adjacent / hypotenuse
cos x = 91 / 350
x = 74.93°

The answer is 74.93°.

Find a point- slope form for the line with slope 1/5 and passing through the point (-4,-6)

weeeeeb [17]

Answer: y-(-6)=1/5(X-(-4))

Step-by-step explanation:

to put together a point slope expresion the equation would be y-y1=m(x-x1)

y1 and x1 being the points on the line and (m) being the slope

what are the coordinate points of A’,B’, and C’ after they were translated right 4 units and up 1 unit??

Alisiya [41]

Answer:

A' = ( -2 , 6 )

B' = ( 7 , 3 )

C' = ( 4 , 0 )

Step-by-step explanation:

Itz askin that if each point is to be shifted 4 units right & 1 unit up then what's the co-ordinates of the new points .

The initial point of A = ( -6 , 5 )

When we shift A for 4 units right , the its abscissa = -6 + 4 = -2 (∵ Right side is considered as positive. So that's why it's +4 )

When we shift A for 1 unit up , its ordinate = 5 + 1 = 6 (∵ Upper side is considered as positive. So that's why it's +1 )

Hence , co-ordinates of A' = ( -2 , 6 )

The initial point of B = ( 3 , 2 )

When we shift A for 4 units right , the its abscissa = 3 + 4 = 7

When we shift A for 1 unit up , its ordinate = 2 + 1 = 3

Hence , co-ordinates of B' = ( 7 , 3 )

The initial point of C = ( 0 , -1 )

When we shift A for 4 units right , the its abscissa = 0 + 4 = 4

When we shift A for 1 unit up , its ordinate = -1 + 1 = 0

Hence , co-ordinates of C' = ( 4 , 0 )
