If I remember correctly, the atomic # will always be the same as the # of electrons
The properties which keep the water temperature from changing much are;
- water's high specific heat capacity
- the large mass of water
<h3>What is specific heat capacity?</h3>
The specific heat capacity is the property of a substance that shows how much its temperature changes when it is exposed to heat.
Thus, the properties which keep the water temperature from changing much are;
- water's high specific heat capacity
- the large mass of water

A.) water's high heat conductivity
B.) water's high specific heat capacity
C.) the iron nail's high heat conductivity
D.) the large mass of water
E.) the iron nail's high specific heat capacity

Answer:
He needs to add 4 mL of the 0.5 M solution to 6 mL of water.
Here we have to choose the right option which tells the moles of CaCl₂ will react with 6.2 moles of AgNO₃ in the reaction
2AgNO₃ + CaCl₂→ 2AgCl + Ca(NO₃)₂
6.2 moles of silver nitrate (AgNO₃) will react with B. 3.1 moles of calcium chloride (CaCl₂).
From the reaction: 2AgNO₃ + CaCl₂→ 2AgCl + Ca(NO₃)₂
Thus 2 moles of AgNO₃ reacts with 1 mole of CaCl₂
Henceforth, 6.2 moles of AgNO₃ reacts with 
= 3.1 moles of CaCl₂.
1 mole of CaCl₂ reacts with 2 moles of AgNO₃. Thus-
A. 2.2 moles of CaCl₂ will react with 2.2×2 = 4.4 moles of AgNO₃.
C. 6.2 moles of CaCl₂ will reacts with 6.2×2 = 12.4 moles of AgNO₃.
D. 12.4 moles of CaCl₂ will reacts with 12.4 × 2 = 24.8 moles of AgNO₃
Thus the right answer is 6.2 moles of AgNO₃ will react with 3.1 moles of CaCl₂.
Because you won’t have enough time to stop and bounce back up before you hit the ground since the cord is the same length as the building.
