<u>Answer:</u> The volume of stock solution of strontium hydroxide needed is 4.125 mL
<u>Explanation:</u>
1 mole of produces 1 mole of strontium ions and 2 moles of hydroxide ions
Molarity of diluted strontium hydroxide solution =
To calculate the molarity of the diluted solution, we use the equation:
where,
are the molarity and volume of the concentrated strontium hydroxide solution
are the molarity and volume of diluted strontium hydroxide solution
We are given:
Putting values in above equation, we get:
Hence, the volume of stock solution of strontium hydroxide needed is 4.125 mL
Answer:
yes....
Explanation:
Let me explain the molecular orbital diagram of N2 using its diagram.
one atom of nitrogen has 7 electrons so a N2 molecule will have 14 electrons
so first 2 electrons go in 1s sigma bond
next 2 in 1s sigma anti bond orbital
next 2 in 2s sigma bond orbital
next 2 in 2s sigma anti bond orbital
next 2 in 2pz sigma bond( assuming that z axis is the internuclear axis ) orbital
<span>Carbon dioxide is one of the important factor in photosynthesis. It helps photosynthesis to take place and it will increase its rate provided the Oxygen supply level at night remains constant.It would probably keep increasing up to 100 percent assuming the light was on. The plant probably needs O2 at night. They generally don't make greenhouses more than about 1000 ppm because the improvement isn't worth the cost of pumping in all that extra CO2. The amount of light that the plant absorbs limits the benefit so it won't increase in proportion to the amount of CO2 past a certain point. It wouldn't be much improvement past about 5000 ppm from what I have heard before.</span>
