The atoms of chlorine are held together by non-polar covalent bonds. Covalent bonds are formed between two or more atoms having zero or very small electronegativity difference. For homonuclear molecules where the two bonding atom are of the same kind, the electronegativity difference is zero.
Answer:
4 m/s
Explanation:
Step 1: Given data
- Mass of the balloon (m): 400 kg
- Kinetic energy of the balloon (KE): 3200 J
Step 2: Calculate the velocity (v) of the balloon
The kinetic energy is the energy that the balloon has due to its movement. We can calculate the velocity of the balloon using the following expression.
v = √(2 × KE/m)
v = √(2 × 3200 J/400 kg) = 4 m/s
Answer:
B. Reese's yard
Explanation:
Because Reese's yard is full of rocks, rock's don't absorb water, while Chris' yard is only soil, which will make his yard absorb water quicker.
Answer:
6.97 moles
Explanation:
Formula Used,
Moles = No. of Molecules ÷ 6.022 × 10²³
Putting Values,
Moles = 4.20 × 10²⁴ ÷ 6.022 × 10²³
Moles = 6.97 moles
