The only difference between the control and the experimental group is the independent variable.
The control group receives no treatment, or a constant independent variable. The experimental group receives a treatment, which is the altering of the independent variable.
Hopefully I helped :)
Answer: B) 200 ml of hot water
Answer:
N2C14
Explanation:
<em> determined the bond type by looking if it is a metal or nometal</em>
<em>Ionic Bond:NM+M</em>
<em>Covalent Bond:NM+NM</em>
We calculate for the number of moles of water given its mass by dividing the given mass by the molar mass.
n water = (36.04 g) / (18 g/mol)
n water = 2 mols
From the given balanced equation, every 6 moles of water produced will require 7 moles of oxygen.
n oxygen = (2 mols H2O) x (7 moles O2 / 6 moles H2O)
n oxygen = 2.33 mols O2
The correct answer is Hydroelectric (D)
