answer
Answer:
No
Step-by-step explanation:
The model shows two similar elements.
Although we do not know what the element is, we can conclude that the model is not a compound.
This is because the definition of a compound is when two different elements join.
However, the model has two similar elements, which forms a molecule, not a compound.
Answer:
The model does not represent a compound because it shows two atoms of the same element combined.
Compounds are made of two or more atoms of different elements.
In a ball-and-stick model of a compound, there should be balls of different colors
Answer:
200 ft 200
t = -------------------- = ---------- min
(S + T) ft/min S + T
Step-by-step explanation:
Recall that distance = (rate)(time).
The distance traveled by the turtle in t minutes is dt = (T ft/min)(t), and
the distance traveled by the snail in t minutes is ds = (S ft/min)(t). We know that ds + dt must be 200 ft.
Thus,
(S ft/min)(t) + (T ft/min)(t) = 200 ft.
The variable t, representing elapsed time, is common to both terms on the left. Thus,
200 ft 200
t = -------------------- = ---------- min
(S + T) ft/min S + T
Answer:
S+T
