Number of ions in the third beaker:
4 Cl⁻ ions
5 Na⁺ ions
1 OH⁻ ion
Explanation:
If you mix the backers the following chemical reaction will occur:
HCl + NaOH → NaCl + H₂O
In the ionic form you write the equation:
H⁺ (aq) + Cl⁻ (aq) + Na⁺ (aq) + OH⁻ (aq) → Cl⁻ (aq) + Na⁺ (aq) + H₂O (l)
where:
(aq) - aqueous (dissolved in water)
(l) - liquid
Number of ions in the first beaker:
4 Cl⁻ ions
4 H⁺ ions
Number of ions in the second beaker:
5 Na⁺ ions
5 OH⁻ ions
Number of ions in the third beaker:
4 Cl⁻ ions
5 Na⁺ ions
1 OH⁻ ion
The rest of H⁺ and OH⁻ ion reacted to form water.

Combine two plants so that each plant's strength compensates for the other's weakness apek
Answer: 63.88 atm
Explanation:
To answer this, we use the formula PV = nRT since the asumption is that the gas has an ideal behavior
where number of mole = 2.60 mol, R(gas constant) = 0.08205746 L atm/K mol,
T = 251 ∘C = (251 + 273) K = 524 K, Volume = 1.75 L
Making Pressure the subject of the formula, we have
P = nRT/V = 2.6 * 0.08205746 * 524/2.75 = 63.88 atm
