Answer:
c) potassium bromide
Explanation:
Since the other three salts have a common ion to the solution (either Ag or Cl), potassium bromide will dissolve more readily. This is due to the common ion effect affecting solubility.
Answer:
60 w
Explanation:
Given :
V= 120V
I=0.5 A
Now,
power can be calculated as :
P=VI
where,
V is voltage
I is current
Now,
P=(120)(0.5)
P=60 W
Therefore, 60w power is delivered to a light
Salt and pepper, soda, chocolate chip cookies, or a Twix™ candy bar, ... are all examples of heterogeneous mixtures<span>, where substances are not mixed on a molecular level.

Answer:
You take the light from a star, planet or galaxy and pass it through a spectroscope, which is a bit like a prism letting you split the light into its component colours. "It lets you see the chemicals being absorbed or emitted by the light source. From this you can work out all sorts of things," says Watson
