Answer:
<h2>
Continue to move at 30 mph</h2>
Explanation:
Newton's first law of motion :
"Every object persists in its state of rest or uniform motion in a straight line unless it is compelled to change that state by forces exerted on it."
From the question we know that the net forces on the object were zero or that the there were no unbalanced forces on it.
Therefore we can assume that the object is moving along a straight line.
And the object was moving at a constant speed of 30 mph.
So it is clear from the Newton's first law that the object will remain in the state of motion as it was earlier.
That is the object will remain in motion at constant speed of 30 mph.
Answer:
(a)
(b) The particles of the formed barium sulfate remain suspended in the aqueous media forming a colloid.
Explanation:
Hello,
In this case, when solutions of barium chloride and sodium sulfate are mixed, the following chemical reaction is carried out:
Thus, we can notice that the product barium sulfate remains solid since its solubility in aqueous media is very low, for that reason at the beginning the solution becomes cloudy as its particles remain suspended in the water forming a colloid. Nevertheless, after some days, the suspended particles get precipitated by the effect of the gravity, therefore, we observe the solid on the bottom of the beaker.

Answer:
Resonance
Explanation:
Resonance is an idea in chemistry that is used to explain such properties as equal bond lengths, bond angles and some other chemical behaviours. Resonance structures show the possible distribution of electrons in molecules. All the contributing canonical or resonance structures give a clue regarding the true structure of the chemical specie under consideration.
The true structure of the specie is somewhere in between that of all the contributing canonical structures. Resonance is often employed to explain properties such as equal bond lengths and bond angles just as typified in the question under consideration.
