A mixture of uneven distribution and easy separation is called. homogeneous a solution heterogeneous a standard
Blizzard [7]

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.

The specific heats and densities of several materials are given below:
krek1111 [17]

<u>Answer:</u> The change in temperature is 84.7°C

<u>Explanation:</u>

To calculate the change in temperature, we use the equation:

q=mc\Delta T

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

\Delta T = change in temperature = ?

Putting values in above equation, we get:

1000Cal=100g\times 0.118Cal/g.^oC\times \Delta T\\\\\Delta T=\frac{1000}{100\times 0.118}=84.7^oC

Hence, the change in temperature is 84.7°C

Breyana and her friend found a piece of metal which they want to
alina1380 [7]

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.
