Question 1 of 11 The graph shows a car's velocity over time.
Velocity versus Time
60
40
Velocity, in mph forward
2 3 45
Time, in seconds (s)
What is the car's acceleration from 0 to 1 second?
A. 10 mph/s
B. 8 mph/s
0 C, 60 mph/s
D. 20 mph/s

b. 8 mph

Explanation:

8

explanation:

each principal energy level above the first contains one s orbital and three p orbitals. a set of three p orbitals, called the p sublevel, can hold a maximum of six electrons. therefore, the second level can contain a maximum of eight electrons - that is, two in the s orbital and 6 in the three p orbitals.

mark brainliest and have a great day!

answer:

the reaction is type of combination reaction.

explanation:

on the product side, there are 2 molecules of bonded to fe   which means one atom of fe are combined two molecules of . so, balanced chemical equation becomes :

this reaction follows the reaction type of combination reaction. a combination reaction is defined as chemical reaction in which reactants combines together to form a single product.
