Answer:
The formula for potassium dihydrogen phosphate is KH2PO4.
It is also know as monopotassium phosphate.
Molecular mass is
(1×39)+(2×1)+(1×31)+(4×16)
=39+2+31+64= 136
Therefore the molecular mass is 136
How much of a product is made depends on the limiting reagent. there are different ways to determine the limiting reagent and this depends on the professor way of teaching it. I will use the must common one. so keep in mind that the way to solve this problem may vary.
first we convert each grams to moles using the molar mass of the molecules. then convert moles to moles of asked molecule (H2O) using the mole-mole ration, and moles of water to grams using the molar mass of water.
molar mass of Na= 23.0 g/mol
molar mass of H₂O= 18.0 g/mol
ratios (based on the balanced equation coefficients)
2 mol Na= 1 mol H₂
2 mol H₂O= 1 mol H₂
calculations:
since H₂O gives less of the product than the other one. H₂O is the limiting reagent and the answer is
4.49 g
Answer:
Pterosaurs are more closely related to crocodilians. They share a more recent common ancestor than do pterosaurs and turtles.
Explanation:
Hope this Helps! :)
Answer:
HF
Explanation:
Hf has hydrogen bonding which is the strongest intermolecular forces. The stronger the IM forces, the higher the boiling point.
Sorry for the delay! My internet is a bit bad.
P is the third sublevel. Each sublevel (the angular momentum quantum number), has its own number:
<span>s = 1, p =3, d = 5, f = 7</span>
The number of electrons for each is:
s-2
p-6
d-10
f-14
It's easier to just memorize these numbers, but the equation for determining the sublevel number is 2n (n = the principal quantum number). The principal quantum number is based on the period the element is in.
