Reducing acidity of chyme :Acidic chyme entering the duodenum stimulates the release of secretin from the small intestinal glands.
Chem bonds by exchanged charges create new characteristics as a result
Answer:
Arsenic (As) anion has -‐3 charge, but also forms cations with +3 or +5 charge.
Explanation:
Answer:
28.43 min
Explanation:
Using integrated rate law for first order kinetics as:
Where,
is the concentration at time t
is the initial concentration
Given that:
The rate constant, k =
min⁻¹
Initial concentration
= 0.1 M
Final concentration
=
M
Time = ?
Applying in the above equation, we get that:-




For #4 first find the molar mass(M) of copper then use that and the mass (m) n=m/M to find moles(n) using moles and the volumes find the concentration using c=n/V
