Answer:
0.1 is the retention factor.
Explanation:
Distance covered by solvent ,
Distance covered by solute or ion,
Retention factor is defined as ratio of distance traveled by solute to the distance traveled by solvent.
0.1 is the retention factor.
Answer:
chemical
Explanation:
because heat is being taken to the egg
<u>Given:</u>
Mass of the ball = 35.2 kg
Momentum = 218 kg m/s
<u>To determine:</u>
The velocity of the ball
<u>Explanation:</u>
Momentum (p) of an object is the product of its mass (m) and velocity (v)
p = m*v
v = p/m = 218 kg.ms-1/35.2 kg = 6.19 m/s
Ans: The velocity of the ball is 6.19 m/s
Answer: Option C) 9.5
Explanation:
Given that,
pOH of solution = ?
pH of solution = 4.5 (it is an acidic solution because any pH values less than 7.0 is said to be acidic)
Recall that pH is the negative logarithm of hydrogen ion concentration in the solution while pOH is the negative logarithm of hydroxide ion concentration in the solution.
Hence, pH + pOH = 14
4.5 + pOH = 14
pOH = 14 - 4.5
pOH = 9.5
Thus, the pOH of the same solution is 9.5
