2. 5 acids: coffee, lemonade, soda pop, orange juice, vinegar
5bases: ammonia, baking soda, cough medicine, liquid soaps
3. Acids are very common in some of the foods we eat.
Bases have properties that mostly contrast with those acids
4. Acid+Base=H2O+Salt
HCI+NaOH=H2O+NaCI
Explanation:
2. (all those acids are strong (in pH meaning those are weak and don't affect you) (most the bases are very strong like ammonia)
4. Salt means any ionic compound formed from an acid/base reaction

Answer:
John Dalton's Atomic Model Below ⬇
Explanation:
Answer:
28.75211 kj
Explanation:
Given data:
Mass of iron bar = 841 g
Initial temperature = 84°C
Final temperature = 7°C
Heat released = ?
Solution:
Specific heat capacity:
It is the amount of heat required to raise the temperature of one gram of substance by one degree.
specific heat capacity of iron is 0.444 j/g.°C
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
ΔT = 7°C - 84°C
ΔT = -77°C
By putting values,
Q = 841 g × 0.444 j/g.°C × -77°C
Q = 28752.11 j
In Kj:
28752.11 j × 1 kJ / 1000 J
28.75211 kj
