Answer:
There are two types of mixtures: heterogeneous and homogeneous. Heterogeneous mixtures have visually distinguishable components, while homogeneous mixtures appear uniform throughout. The most common type of homogenous mixture is a solution, which can be a solid, liquid, or gas.
Hope this helped :)
The answer is D. CaCl2 and H2O
Boiling I think! hope you get it right
The statement that defines the specific heat capacity for a given sample is the quantity of heat that is required to raise 1 g of the sample by 1°C (Kelvin) at a constant pressure.
<h3>What is specific heat capacity?</h3>
Specific heat capacity is the of heat to increase the temperature per unit mass.
The formula to calculate the specific heat is Q = mct.
The options are attached here:
- The temperature of a given sample is 1 %.
- The temperature that a given sample can withstand.
- The quantity of heat that is required to raise the sample's temperature by 1 °C1 °C (Kelvin).
- The quantity of heat that is required to raise 1 g of the sample by 1°C (Kelvin) at a constant pressure.
Thus, the correct option is 4. The quantity of heat that is required to raise 1 g of the sample by 1°C (Kelvin) at a constant pressure.

C. 0.1 M HCl
Explanation:
The solution with the lowest molarity is the most dilute of all.
This is why the choice is 0.1M of HCl.
Molarity is the same as concentration. The unit "M" denotes mole per liter volume of solution.
- Molarity is defined as the number of moles of solute in a give volume of solution.
- 0.1M means 0.1mole of HCl is dissolved in 1liter of solvent.
- The higher the number of moles dissolved and the more the concentration of the solution will be.
The order of increasing concentration is:
0.1M < 0.2M< 0.3M < 0.4M
