They all have the same number of electrons in their outer shell.
Answer:
Option A= copper
Explanation:
According to specific heat capacity of substances, copper will reach to the our body temperature first.
Specific heat capacity:
It is the amount of heat required to raise the temperature of one gram of substance by one degree.
Formula:
Q = m × c × ΔT
specific heat capacity of copper = 0.385 J/g. °C
specific heat capacity of aluminium = 0.902 J/g. °C
so copper will absorb the heat very quickly and raise the temperature in very less time as compare to aluminium.
Yes, we can dissolve 35 moles of KMnO₄ into 500 mL of water to give a molarity of 70 M
<h3>What is molarity? </h3>
Molarity is defined as the mole of solute per unit litre of solution. Mathematically, it can be expressed as:
Molarity = mole / Volume
<h3>How to determine the molarity </h3>
- Mole of KMnO₄ = 35 moles
- Volume = 500 mL = 500 / 1000 = 0.5 L
Molarity = mole / Volume
Molarity = 35 / 0.5
Molarity = 70 M
