Methyl red is a common acid-base indicator. it has a ka equal to 6.3 × 10–6. its un-ionized form is red and its anionic form is
Maksim231197 [3]
Hello!

The pKa of an indicator tells us the pH where it changes color. The pKa of Methyl red is 

pKa=-log(Ka)=-log( 6,3*10^{-6} )=5,20

So, at a pH=7,8, Methyl Red would be at a pH over its pKa, so it would be in its basic form. The Basic Form of Methyl Red is Yellow, so the solution would be Yellow.

Have a nice day!

Can someone please help me ?
DochEvi [55]

Answer:

The acceleration of ball is 18 m/s².

Explanation:

Definition:

The acceleration is rate of change of velocity of an object with respect to time.

Formula:

a = Δv/Δt

a = acceleration

Δv = change in velocity

Δt = change in time

Units:

The unit of acceleration is m.s⁻².

Acceleration can also be determine through following formula,

F = m × a

a = F/m

Given data:

Mass of ball = 0.60 kg

Force on it = 10.8 N

Acceleration = ?

Solution:

a =  10.8 N/0.60 kg

a = 18 N/kg

N = kg.m/s²

a = 18 kg.m/s² / kg

a = 18 m/s²
