Answer:
Honey
Explanation:
It’s honey because the item that was dropped in it is almost at the top and that means there is something sticky or force there holding it back!
Answer:
1.5 mol.
Explanation:
- It is known that every 1.0 mole of compound or element contains Avogadro's number (6.022 x 10²³) of molecules or atoms.
<u><em>Using cross multiplication:</em></u>
1.0 mole of H₂ contains → 6.022 x 10²³ molecules.
??? mole of H₂ contains → 9.03 x 10²³ molecules.
∴ The no. of moles of H₂ contains (9.03 x 10²³ molecules) = (1.0 mol)(9.03 x 10²³ atoms)/(6.022 x 10²³ atoms) = 1.5 mol.
Answer:
1.196 M NaOH
Explanation:
Molarity = moles/Volume (L)
moles NaOH = mass NaOH/MM NaOH = 12/40.01 = 0.299 moles NaOH
Volume solution = 250 mL = 0.250L
M = 0.299/0.250=1.196 M NaOH
A and b are related because if u look carefully at what its showing u that there both the same but what its telling u is not the same.
a and c are the same but the picture is different and also the way they describe it is different and what they want u to look at is that if you look at it closely then youll know the difference and how to find it as well
E = HF, where H is Planck's constant, 6.63 x 10 - 34 j.s
