Answer:
The last answer would be correct because if you have ever done it before you would know that rubbing your feet (just like the rubbing of ice crystals) on the carpet will create the energy you need, then once you touch the metal it creates that spark!
Explanation:
hoped that helped-I would be thankful for brainliest ;)
Answer:
Bonding Order = number of bonding electrons – number of antibonding electrons/2.
So for CO2, there is a total of 16 electrons, 8 of which are antibonding electrons.
So 16 – 8 = 8; divided by 2 = 4. So, 4 is the bonding order of CO2. The molecular structure of CO2 looks like this:

O=C=O

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:
[A] + [B] decrease rapidly.
[CD] increases rapidly.
Explanation:
<em>A + B → CD,</em>
The reaction proceeds that A reacts with B and their concentration decreases to produce CD that its concentration increases with time.
At the beginning of the reaction; the concentration of A + B decreases rapidly and the concentration of CD increases rapidly.
<em>Kindly, see the attached image.</em>

[A] + [B] decrease rapidly.
[CD] increases rapidly.
