A) Na + H20 ----> NaOH + H2
B) 2Na + 2H20 ----> 2NaOH + H2
Follow exact same process as your other questions I have answered.
Well it's definitely an alkaline solution.
Answer:
No streak of light will appear.
Reason I given below.
Explanation:
No streak of light will be seen.
This is because as it falls to the moon, the gravitational pull plus the dense atmosphere which was necessary to produce friction when it fell to the earth are not present in this case and as such the whole meteor is not burnt like it did when it fell to the earth.
Answer:
The answer is
<h2>2.25 mL</h2>
Explanation:
The volume of a substance when given the density and mass can be found by using the formula

From the question
mass = 6.2 g
volume = 2.75728 g/cm³
The volume is

We have the final answer as
<h3>2.25 mL</h3>
Hope this helps you
Answer:
ExplanaA) A decrease in reactant concentration reduces the frequency of successful collisions. tion:
As a reactant gets used up, there are fewer molecules present to collide with others. A reaction depends on molecular collisions. When there are fewer collisions, the reaction slows down.
B) is wrong. A reaction is usually carried out at constant temperature,
C) is wrong. Not all reactions need catalysts.
D) is wrong. If the temperature is constant, pressure will have little effect on the movement and energy of molecule.
