In some kind of a 0.800 m ba(oh)2 solution, each individual ion has a concentration of 1.81M.
<h3>What are the 5 most common electrolytes?</h3>
Together with magnesium, calcite, phosphate, and bicarbonates, salt, potassium, & chloride are the important electrolytes. We obtain electrolytes from our diet and drinks. Unbalanced amounts of these electrolytes might result in either low or high levels.
<h3>Briefing:</h3>
In a solution of Ba(OH)2 at a concentration of 0750 M, Ba2+ is the predominant ion. = 0.800M and OH⁻ = 1.50 M.
The dissociation equation is:
Ba(OH)²(s)=Ba²+aq+2OH-aq
Using the Ba(OH)2 mole ratio: Ba₂⁺which is 1: 1 the concentration of Ba² is = 0.750M
By utilising Ba(OH)2's mole ratio: which is 1:2 the concentration of
OH=0.800*2/1
=1.81M
Individual ion concentration is therefore ba(oh)2 = 0.800M & = 1.81M.

The cell will gain water and eventually swell up and burst
Answer:
T₂ = 19.95°C
Explanation:
From the law of conservation of energy:
where,
mc = mass of copper = 37.2 g
Cc = specific heat of copper = 0.385 J/g.°C
mw = mass of water = 188 g
Cw = specific heat of water = 4.184 J/g.°C
ΔTc = Change in temperature of copper = 99.8°C - T₂
ΔTw = Change in temperature of water = T₂ - 18.5°C
T₂ = Final Temperature at Equilibrium = ?
Therefore,
<u>T₂ = 19.95°C</u>
Given what we know about the forces that act upon objects, we can confirm that an object to which balanced forces are applied will not be in motion.
<h3>What are
balanced and
unbalanced forces?</h3>
- A balanced force is when an object is not in motion due to all forces being matched.
- This means that for every force, there is an opposite force of the same magnitude that nullifies it.
- When one of these forces increases and overtakes its opposite, we gain motion.
- When this happens, the forces are now unbalanced.
Therefore, we can confirm that since the forces that are acting on the object are balanced, meaning that each force is matched by an opposite force of the same magnitude, the object will not move. For this object to move, the forces would have to become unbalanced by increasing the magnitude of one.

Answer:
The answer to your question is 6.54 g of H₂O
Explanation:
Data
mass of water = ?
mass of carbon dioxide = 16 g
Balanced chemical reaction
H₂CO₃ ⇒ H₂O + CO₂
Process
1.- Calculate the molar mass of the products
H₂O = (1 x 2) + (1 x 16) = 2 + 16 = 18 g
CO₂ = (1 x 12) + (16 x 2) = 12 + 32 = 44 g
2.- Use proportions and cross multiplication to solve this problem.
18 g of H₂O -------------------- 44 g of CO₂
x -------------------- 16 g of CO₂
x = (16 x 18) / 44
x = 288/44
x = 6.54 g of H₂O
