Answer:
F = V / T
= 
= 42ml/hr
Explanation: first convert time into hours,then deduce the formula for the flow rate
solution:
The general form of the equation would be A = P x (1/2) ^ (t/h) where A = final amount, P = start amount, t = time (here in days) and h = half-life (has to be same units as t)
a) A = 192 x (1/2) ^ (15/5) = 192 x (1/2) ^3 = 192 x 1/8 = 24 mg
Answer:- Water is an electronegative molecule.
Explanation:
A molecule cannot be electronegative. Rather the atoms in a molecule may be electronegative. This first statement does not account for the hydrogen bonding in water at all because it is incorrect. However, the other statements in the question sheds more light on the nature of hydrogen bonding in water molecule.
Equations represents the law of conservation of mass is 2H₂O → 2H₂ + O₂
Law of conservation of mass stated that energy neither be created nor destroyed called as law of conservation of mass and as the same no of each atom present in the both side of the reaction this reaction represents the law of conservation of mass so in the equation 2H₂O → 2H₂ + O₂ the energy cannot be created nor destroyed water can form 2 mole of hydrogen and 1 mole of oxygen which form water
