Answer is: A) Sr (strontium).
The reactivity series<span> is a series of metals from highest to lowest reactivity.</span><span> Metal higher in the reactivity series will displace another.
</span>Strontium is only higher in this group from magnesium. Strontium is stronger reducing agent than magnesium, gives electrons easier.
Any colloid consisting of a solid dispersed in a gas is called a smoke. A liquid dispersed in a gas is referred to as a fog. So the answer would be smoke
Answer:

Answer:
<h3>The answer is 23.8 miles</h3>
Explanation:
The distance covered by an object given it's velocity and time taken can be found by using the formula
<h3>distance = velocity × time</h3>
From the question
velocity = 35.0 mi/hr
time = 2455 s = 0.68 hr
We have
distance = 35 × 0.68
We have the final answer as
<h3>23.8 miles</h3>
Hope this helps you
