Answer:

Changes in colour of litmus paper.

  • Blue litmus turns red under acidic conditions.
  • Red litmus turns blue under basic conditions.

Noe

PH values:-

  • K=4
  • M=11

K is acidic as pH is <7

Hence K will change the colour of blue litmus paper.

#B

Examples of substances

  • K=Vinegar, Tomatoes.

An animal skeleton has a carbon-14 decay rate of 13.1 disintegrations per minute per gram of carbon. When did the animal die? (A
Olenka [21]

Answer:

1034 yrs

Explanation:

The equation to use in this question is:

t = -2.303/k log (A/A₀) where

A=    present number of disintegrations

A₀ =  intial number of disintegrations

k =  decay constant

The decay constant we will obtain it from the given hal-life:

k: 0.693/t₁/₂,        t₁/₂ = half-life   ⇒

k: 0.693 / 5730 y =  1.209 x 10⁻⁴ /y⁻¹

t = - 2.303 / 1.209 x 10⁻⁴ /y⁻¹ x log (13.1/15.3) =  1034 yrs
