The solutes dissolves in solvent results in the formation of a solution.
Those mixtures in which the components of mixture are uniformly distributed throughout the mixture are said to be homogeneous.
Those mixtures in which the components of mixture are not uniformly distributed throughout the mixture are said to be heterogeneous.
Those solutions whose concentrations are accurately known are known as standard.
Hence, a mixture of uneven distribution and easy separation is heterogeneous.

<u>Answer:</u> The change in temperature is 84.7°C
<u>Explanation:</u>
To calculate the change in temperature, we use the equation:
where,
q = heat absorbed = 1 kCal = 1000 Cal (Conversion factor: 1 kCal = 1000 Cal)
m = mass of steel = 100 g
c = specific heat capacity of steel = 0.118 Cal/g.°C
= change in temperature = ?
Putting values in above equation, we get:
Hence, the change in temperature is 84.7°C
Answer:
The density of beryllium is 1.85 g/cm³. Thus given metal is beryllium.
Explanation:
Given data:
Mass of metal = 37 g
Volume of metal = 20cm³
Which metal is this = ?
Solution:
We will solve this problem by using density formula. After finding density we will check from literature which metal has a density similar to our calculated density.
d = m/v
d = 37 g/ 20cm³
d = 1.85 g/cm³
The density of beryllium is 1.85 g/cm³. Thus given metal is beryllium.
