Answer: For Number #1)
The solution above is an acidic solution
Kw= {H+}*{OH^-}
[OH^-] =Kw/[H+]
OH^-= 1.0*10^14/ 1.0*10^-4
=1.0*10^4
Answer:
Mass is the amount of matter in an object and does not change with location.
Explanation:
Answer:
Q = 940.5 j
Explanation:
Given data:
Mass of iron = 95 .00 g
Initial temperature = 36.0°C
Final temperature = 58°C
Heat lost = ?
Solution:
Formula:
Q = m.c. ΔT
Q = amount of heat absorbed or released
m = mass of given substance
c = specific heat capacity of substance
ΔT = change in temperature
Specific heat capacity of iron = 0.450 j/g.°C
ΔT = T2-T1
ΔT = 58°C-36.0°C
ΔT = 22°C
Q = m.c. ΔT
Q = 95.00 g × 0.450 j/g.°C × 22°C
Q = 940.5 j
The reaction of
Sugar unit with
Acetic Anhydride is known as
Acylation Reaction, in which a
ester group is formed. These Esters are formed by treating Monosaccharide with Acetic Anhydride in the presence of catalyst i.e. Pyridine. The reaction is given below,
