Answer:
Equal
Explanation:
Energy is always conserved in the nature and it is an universal law. According to the law conservation of energy, it is said that energy can never be created out of something and we can never destroy and vanish any energy in any form. Energy in any form can only be transformed to some other forms of energy. This is known as conversion of energy.
In the context, the chemical energy that is produced by the battery and the electrical energy produced should be equal.
Answer:
See answer below
Explanation:
a.) Lithium Chloride, LiCl is soluble in water.
b.) Silver Chloride, AgCl is insoluble in water.
c.) Barium Carbonate, BaCO3 is insoluble in water.
d.)Potassium, K2 is soluble in water.
e.) Iron (III) Nitrate Fe(NO3)3 is soluble in water.
- All nitrates (NO3) are soluble in water.
- Alkali metals are soluble in water.
- Chlorides are soluble in water with the exception of AgCl and a few others.
- Carbonates are generally insoluble in water.
Nitrogen is a gas because it is an airlike fluid substance which expands freely to fill any space available, irrespective of it's quantity
Answer:
27.6mL of LiOH 0.250M
Explanation:
The reaction of lithium hydroxide (LiOH) with chlorous acid (HClO₂) is:
LiOH + HClO₂ → LiClO₂ + H₂O
<em>That means, 1 mole of hydroxide reacts per mole of acid</em>
Moles of 20.0 mL = 0.0200L of 0.345M chlorous acid are:
0.0200L ₓ (0.345mol / L) = <em>6.90x10⁻³ moles of HClO₂</em>
To neutralize this acid, you need to add the same number of moles of LiOH, that is 6.90x10⁻³ moles. As the LiOH contains 0.250 moles / L:
6.90x10⁻³ moles ₓ (1L / 0.250mol) = 0.0276L of LiOH =
<h3>27.6mL of LiOH 0.250M</h3>
Yes what the other person said can I plz get an thanks
