The energy transferred in joules is calculated using the below formula

Q(heat energy) = M(mass) x C (specific heat capacity ) x delta T(change in temperature
delta T = 0. 0c- 14 c = -14 c
M= 29.5 g
C of water is always = 4.18 j/g/c

= 29.5 g x -14 c x 4.18 j/g/c =-1726.34 joules are needed when 29.5 g of liquid water decrease from 14 c to 0.0 C

Give the spectator ions for the reaction that occurs when aqueous solutions of H 2SO 4 and KOH are mixed.

Sever21 [200]

Answer:

The spectator ions is: $K^+$ and $SO^{2-}_4$

Explanation:

The equation of reaction between H₂ SO₄ and KOH is:

$H_2SO_{4(aq)} + 2KOH _{aq} \to K_2SO_{4(aq)} +2H_2O _{(l)}$

Rewriting this equation as ionic;

$[2H^{+} + SO^{2-}_4 + 2K^+ +2OH^- \to 2K^+ SO_4^{2-} + 2H_2O ]$

Spectators ions are ions present on both sides of the ionic equation by the same quantity but do not take part in the net reaction.
