Main Answer:
Given data:
Mass of ice m = 12 grams = 12/1000 = 0.012 kg
Specific heat s = 4.18 KJ/ gm-1 C-1
Change in temperature t = t2 - t1
t = 100 - (-10)
t = 100 + 10 = 110C
Heat required Q = m x s x t
Q = 0.012 x 4.18 x 110
Q = 5.5176 KJ
Explanation:
What is heat?
Heat is defined as one of the forms of energy. It is a kinetic energy which can be transferred from one object to another object or medium. It cannot be destroyed or created. The units of heat is Joules in SI system and calories in CGS system.

Answer:
0.500 M
Explanation:
The balanced equation for the neutralization reaction is as follows
NaOH + HCl —> NaCl + H2O
Molar ratio of NaOH to HCl is 1:1
Number of moles of NaOH reacted is equal to the number of HCl moles
We can use the following equation
c1v1 = c2v2
Where c1 is concentration and v1 is volume of HCl
c2 is concentration and v2 is volume of NaOH
Substituting the values
1.00 M x 10.0 mL = c2 x 20.0 mL
c2 = 0.500 M
Concentration of NaOH is 0.500 M
Answer:
The responding variable of this experement is the outcome and that would be that the one in lemon juice responded and the one in water didn't (the other one is the control). Thus the responding varible is the one in lemon juice.
