Strontium, Calcium, Magnesium
Strontium is the most reactive of the three element because of this, it does not exist free in nature but rather exist in combination with other elements in various compounds such as strontianite. Calcium is more reactive than magnesium because it is larger than magnesium and thus, it is more electropositive in nature.
Chemical, if it gives off a reaction like that its chemical
Answer:
Explanation:
We were told to rinse the buret with the base so that the concentration won't be messed up, but when it comes to the flask that is going to hold the acid, there is no need to rinse, because it would not affect the result if it has water in it.
Hydrogen bond is found between water molecule if im correct
Answer:
17.27 atm
Explanation:
Use the ideal gas law or PV = nRT
We are solving for pressure here so lets isolate for P before we plug in values:

So first to get n or the number of moles we need to convert the grams of N2O to moles of N2O. We can do this by multiplying by the inverse of the molar mass like so:

Our grams of N2O would cancel and give us 11.813 mol of N2O
Now all thats left is to plug in and solve with the correct value for R which in this case for all of our units to cancel is 0.08206

P = 17.27 atm
(I would double check the calculator work if it is for correctness just be sure)
