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.

Answer: The concentration of the KOH solution is 1.01 M
Explanation:
According to neutralization law:
where,
= basicity of 
= 1
= acidity of KOH = 1
= concentration of HCl = 3.00 M
= concentration of KOH = ?
= volume of HCl = 35.3 ml
= volume of KOH = 105.0 ml
Putting the values we get:
Thus the concentration of the KOH solution is 1.01 M
Answer:
Explanation:
Azimuthal maps projection is the easiest for plotting travel by airplane because Azimuthal maps make the UV plane to be tangent to the globe and it's make the directions from the center of projections to be correct and accurate to any other points , likewise circles are also projected directly to the straight lines on the plane. And this is because Any line that is normally drawn through the tangent point give distance correctly and accurately.
Answer:
Force of Tension = 1832.8 N
Explanation:
Any mass of object supported or pulled by a rope or cable is subject to a force of tension. Since the mass is raised by a cable, tension is involved.
Mathematically,
Tension = mass × gravity(9.8 m/s²)
Tension can be represented as
T = (m × g) + (m × a)
Where g is the acceleration due to gravity of the object the cable is supporting and a is the acceleration on the object the cable is supporting. And m is the mass of the object.
mass = 158 kg
a = 1.8 m/s²
g = 9.8 m/s²
T = mg + ma
T = m(g + a)
T = 158(9.8 + 1.8)
T = 158 × 11.6
T = 1832.8 N
