B is the correct answer if I remember
Answer:
6080 N
Explanation:
From the question given above, the following data were obtained:
Mass (m) of car = 800 Kg
Acceleration (a) of car = 7.6 m/s²
Force (F) =?
The force experienced by the car can be obtained as illustrated below:
Force (F) = mass (m) × acceleration (a)
F = m × a
F = 800 × 7.6
F = 6080 N
Thus, the experience a force of 6080 N
<u>Q</u><u>U</u><u>E</u><u>S</u><u>T</u><u>I</u><u>O</u><u>N</u><u> </u><u>:</u>
- highest energy level for lithium
<u>A</u><u>N</u><u>S</u><u>W</u><u>E</u><u>R</u><u> </u><u>:</u>
- There are 2 electrons on the first energy level and 1 electron on the second. Explain that the first energy level can only have 2 electrons so the next electron in lithium is on the next (second) level. Explain that neon has 10 protons and 10 electrons.
Answer:

Explanation:
We will need a balanced chemical equation with masses, moles, and molar masses.
1. Gather all the information in one place:
Mᵣ: 18.02
2Na + H₂O ⟶ 2NaOH + H₂
m/g: 72.0
2. Moles of H₂O

3. Moles of Na
The molar ratio is 2 mol Na/1 mol H₂O.
