The first animal was called the comb jelly
Answer:
Radioactive decay occurs in unstable atomic nuclei – that is, ones that don't have enough binding energy to hold the nucleus together due to an excess of either protons or neutrons.
Hope this helps!
The volume, in liters, per kg of the Himalayan pink salt would be 0.97 L
Recall that: density = mass/volume
Hence: volume = mass/density
In this case, the density of the Himalayan pink salt is 1.03 while the mass we are working with is 1 kg.
1 kg is equivalent to 1000 g
Thus: volume = 1000/1.03
= 970.87 mL
Divide by 1000 to convert to L
970.87/1000 = 0.97 L
