Answer:
Amount of heat absorbed by water is 2604.54 J.
Explanation:
Amount of heat absorbed by water =
where m represents mass, C represents specific heat and represents change in temperature.
Here g ,
and
= (final temperature - initial temperature) = (29.5-21.2)
= 8.3
So, amount of heat heat absorbed by water
=
= 2604.54 J
Answer:
0.1357 M
Explanation:
(a) The balanced reaction is shown below as:
(b) Moles of can be calculated as:
Or,
Given :
For :
Molarity = 0.1450 M
Volume = 10.00 mL
The conversion of mL to L is shown below:
1 mL = 10⁻³ L
Thus, volume = 10×10⁻³ L
Thus, moles of :
Moles of = 0.00145 moles
From the reaction,
1 mole of react with 2 moles of NaOH
0.00145 mole of react with 2*0.00145 mole of NaOH
Moles of NaOH = 0.0029 moles
Volume = 21.37 mL = 21.37×10⁻³ L
Molarity = Moles / Volume = 0.0029 / 21.37×10⁻³ M = 0.1357 M
