Answer:
Molarity of solution = 0.77 (Approx.)
Explanation:
Given:
Moles of LiCl = 0.529
Volume of water = 687
Find:
Molarity of solution
Computation:
Molarity of solution = [Moles/Volume]1000
Molarity of solution = [0.529/687]1000
Molarity of solution = 0.77 (Approx.)
The two liquids made a new substance.
<h3>What is a physical and chemical change?</h3>
A chemical change results from a chemical reaction, while a physical change is when matter changes forms but not chemical identity.
A chemical change occurs when some substances are transformed into different substances, with different nature and properties. In this case when both liquids are mixed a solid is formed. This is an example of a change of state of the liquids reactants to the solid product, which has properties and characteristics different from that of the initial liquids of the mixture which is called a chemical change.
Hence, option D is correct.

Answer:
Heat is transferred from the warmer block to the cooler block
Explanation:
Heat transfer by conduction involves two or more solids. The heat generally moves from a part at higher temperature to one with a lower temperature.
- Heat transfer is based on the differences in temperature profile on a body.
- When the temperature of the body is the same, heat is not transferred.
- The molecules that makes up the hotter body collides with static molecules of the cold one.
- Through this, heat is transferred.
Fahrenheit to Celsius-> subtract 32 and multiply by .5556
Celsius to Fahrenheit-> multiply by 1.8 and add 32
Halogens are a group of elements found in the periodic table. They are the elements found in Group VIIA. It consists only of five chemical elements which are fluorine, chlorine, bromine, iodine and astatine. They are called as such because they are the salt formers.
