Yes, they are synonymous terms.
Answer:
reactants
Explanation:
The reaction model is given as shown below:
4Fe + 3O₂ → 2Fe₂O₃
The name that describes the iron and oxygen found on the left hand side of Leann's model is reactants.
Reactants in a chemical expression are the species that are combining together to give a product.
Some reactions only have one reactant and such a chemical process is often termed decomposition reaction.
The two moles of Fe₂O₃ is the product of the reaction.

if the image is on the book yes , no its can be both
Explanation:
Answer:
x₁ = 0.1878 m
Explanation:
For this exercise we will use conservation of energy
starting point. Highest point
Em₀ = U = m g h
final point. Lowest point with fully compressed spring
Em_f = K_e + U
Em_f = ½ K x² + m g x
energy is conserved
Em₀ = Em_f
m g h = ½ K x² + m g x
½ K x² + mg (x- h) = 0
let's substitute
½ 7.3 x² + 0.030 9.8 (x- 0.25) = 0
3.65 x² + 0.294 (x- 0.25) = 0
x² + 0.080548 (x- 0.25) = 0
x² - 0.020137 + 0.080548 x = 0
x² + 0.080548 x - 0.020137 = 0
let's solve the quadratic equation
x = [0.080548 ±√ (0.080548² + 4 0.020137)] / 2
x = [0.080548 ± 0.29502] / 2
x₁ = 0.1878 m
x₂ = -0.1072 m
These are the compression and extension displacement of the spring
Answer:
d) F
Explanation:
According to columb's law:
"The magnitude of electrostatic force between two charges is directly proportional to the product of magnitude of two charges and inversly proportional to separation between them."
If q₁ and q₂ are magnitude of two charges, d is distance between them and k is dielectric constant, then force F is given by
According to this force exerted on point charge Q is same as that of 3Q, so force point 3Q charge experience is also F
