When stress, toxins or lack of essential nutrients weaken digestion, harder to digest foods like grains and cow dairy, meat and processed foods contribute to maldigestion, dysbiosis and impaired digestive competence.
the number of Valence electrons remains the same
Answer:
the answer is A
Explanation:
physical changes does not change the property of matter.
The volume of 0.160 m Li2S solution required to completely react with 130 ml of 0.160 CO(NO3)2 is calculated as below
write the reacting equation
Co(NO3)2 + Li2S = 2LiNO3 + COS
find the moles of CO(NO3)2 = molarity x volume
= 130 ml x 0.160=20.8 moles
since the reacting moles between CO(NO3)2 to LiS is 1:1 the moles of LiS is also 20.8 moles
volume of Lis is therefore = moles of Lis/ molarity of LiS
= 20.8/0.160 = 130 Ml
