Heat is occasionally
called a process quantity<span>, for the reason that it is defined in the background of a
process by which energy can<span> be transported.
</span>The consequence of heat on water hinge
on whether the energy is touching into the water (endothermic)
or touching out of the water (exothermic). When water molecules
get energy, the average speed of the molecules rises; this is computed
as a temperature change if enough energy is
gained.</span>
Answer: Option (a) is the correct answer.
Explanation:
Non-metals are the species which in order to complete their octet readily gain an electron.
For example, fluorine is a non-metal with atomic number 9 and its electronic distribution is 2, 7.
Hence, to attain stability it readily accepts an electron from a donor atom.
Some characteristics of non-metals are as follows.
Non-metals do not conduct electricity.
Non-metals are brittle in nature and they have a rough surface.
Non-metals are not malleable or ductile.
Thus, we can conclude that non-metals do not conduct electricity is a characteristic of non-metals.
Answer:
0.423g
Explanation:
akording to mass = concetration x volume
Is correct hope this helps i have done this before
Answer:
0.209 mol/L
Explanation:
Given data
- Mass of copper(lI) sulfate (solute): 11.7 g
- Volume of solution: 350 mL = 0.350 L
The molar mass of copper(Il) sulfate is 159.61 g/mol. The moles corresponding to 11.7 grams are:
11.7 g × (1 mol/159.61 g) = 0.0733 mol
The molarity of copper(Il) sulfate is:
M = moles of solute / liters of solution
M = 0.0733 mol / 0.350 L
M = 0.209 mol/L
