We can skip option B and D because NaCl is salt and H₂SO₄ is a strong acid.
Neutralization reactions are those reactions in which acid and base react to form salt and water.
As water being amphoteric in nature can react with HCl as follow,
HCl + H₂O ⇆ H₃O⁺ + OH⁻
In this case no salt is formed, so we can skip this option.
Ammonia being a weak base can abstract proton from HCl as follow,
HCl + NH₃ → NH₄Cl
Ammonium Chloride is a salt. So, among all four options, Option-C is the correct answer.
<span> The temperature of the water in both beakers is greater than 8 °C
This is because since the water passes on heat to the spheres, that means they are at a higher temperature then the spheres. if they were at a lower temp. The spheres would pass on heat to the water.

Answer:
The specific heat capacity of quartz is 0.71 J/g°C.
Explanation:
Heat lost by quartz will be equal to heat gained by the water
Mass of quartz= 
Specific heat capacity of quartz= 
Initial temperature of the quartz= 
Final temperature = 
Mass of water=
Specific heat capacity of water= 
Initial temperature of the water = 
Final temperature of water = 
On substituting all values:
we get:
The specific heat capacity of quartz is 0.71 J/g°C.

Answer: 0.1 km
Explanation:
1) Multiply the rate (speed) by the time: 2 cm / year × 5,000 year = 10,000 cm
2) Convert cm to km, using these well know conversion factors:
1 km = 1,000 m
1 m = 100 cm
⇒ 10,000 cm × [1 m / 100 cm] × [1 km / 1,000 m] = 0.1 km
