The bowl of mixed fruits is a mixture because there are several things making up the object. Hence, option (B) is correct.
What is a mixture?
- The matter is categorized as mixtures and pure substances.
- A mixture is defined as a combination of substances that are not chemically mixed.
- A mixture can exist in solid, liquid, or gas form.
- A mixture can exist in the same or in a different phase. It can be homogenous or heterogeneous.
- If the substances are combined in the same phase, then the mixture is a homogeneous mixture.
- But if the substances are combined in different phases, then it is a heterogeneous mixture.
Therefore, the mixed fruit bowl is a mixture, because there are several things making up the object.
Hence, option (B) is correct.

Answer:
15L will be the final volume
STEPS:
.50 + .25 = .75
.25/5 ÷ .75/x
(.75*5=3.25)
.25x = 3.25
x=15

Answer:
Some elements have variable valencies because of the different electronic configurations. An atom of an element can sometimes lose more electrons than are present in its valence shell i.e. loss from the penultimate shell and hence exhibit more than 1 or variable valency.
Explanation:
Hope it helps.
Answer:
An unsaturated solution.
Explanation:
Hello there!
In this case, according to the given information, it turns out possible for us to firstly realize we need to calculate the grams of vanillin in 0.070 moles by using its molar mass of 152.15 g/mol:
Thus, since the solubility is 10.65 g per 1 L of solution, we can notice 5.00 g will complete dissolve and produce an unsaturated solution.

The value 6.0 x 10^3- 2.3 × 10^3 in scientific notation is 3.7 × 10^3.
<h3> What is scientific notation?</h3>
Scientific notation is a way to write very large or very small numbers so that they are easier to read and work with.
You express a number as the product of a number greater than or equal to 1 but less than 10 and an integral power of 10 .
<h3>Why it is used? </h3>
There are two reasons to use scientific notation.
- The first is to reveal honest uncertainty in experimental measurements.
- The second is to express very large or very small numbers so they are easier to read.
Given,
= 6.0 x 10^3- 2.3 × 10^3
= (6.0 - 2.3) × 10^3
= 3.7 × 10^3
Thus, we find that the value 6.0 x 10^3- 2.3 × 10^3 in scientific notation is 3.7 × 10^3.
