Answer:
<em><u>"</u></em><em><u>[</u></em><em><u>Temperature is a measurement of the average kinetic energy of the molecules in an object or a system. Kinetic energy is the energy that an object has because of its motion. The molecules in a substance have a range of kinetic energies because they don't all move at the same speed</u></em><em><u>.</u></em><em><u>]</u></em><em><u>"</u></em>
The correct option is 3.
In the presence of oxygen, iron will react with water to form rust. This is a chemical reaction and it is one of the chemical properties of iron.
Chemical properties refers to those properties of a substance, which can be used to identify it chemically, that is by reason of chemical reactions. Examples of chemical properties are reactivity with water, heat of combustion, electromotive force, pH, etc.<span />
Moles Cu+2 = M * V
= 0.05 L * 0.011 m
= 0.00055 moles
when the molar ratio of Cu2+: EDTA = 1:1 so moles od EDTa also =0.00055 moles
and when the Molarity of EDTa = 0.0630 M
∴ Volume of EDTA = moles / Molarity
= 0.00055 / 0.0630
= 0.0087 L = 8.7 L
Answer:
C is the answer I believe
