The overall balanced
chemical reaction for this is:
Detonation of
Nirtoglycerin <span>
4 C3H5N3O9 --> 12 CO2 + 6 N2 + O2 + 10 H2O </span>
Therefore:
2.00 mL x 1.592 g/mL =
3.184 g <span>
3.184 g / 227.1 /mol = 0.0140 mol nitroglycerin
4 moles --> 12 + 6 + 1 + 10 = 29 moles of gas
<span>0.0140 mol x (29/4) = 0.1017 moles of gases or (0.102 mol) </span></span>
Answer:
Na < K < S < Be
Explanation:
Let's work with NA and molar mass of each.
- 1.5 mol of K → should be converted to atoms ( mol . NA)
1.5 mol . 6.02×10²³ = 9.03×10²³ atoms of K
- 64 g of S → should be converted to mol (mass / molar mass). Then, into atoms. (mol . NA)
64 g / 32.06 g/m = 1.99 mol
1.99 m . 6.02×10²³ = 1.20×10²⁴ atoms of S
- 20 g of Be → should be converted to mol (mass / molar mass). Then, into atoms. (mol . NA)
20 g / 9.01 g/m = 2.22 moles
2.22 m . 6.02×10²³ = 1.33×10²⁴ atoms of Be
- 25 g of Na → should be converted to mol (mass / molar mass). Then, into atoms. (mol . NA)
25 g / 23 g/m = 1.08 moles
1.08 m . 6.02×10²³ = 6.54×10²³ atoms of Na
Answer:
the boiling point of HF is higher than H2 and F2
Explanation:
it is because inter molecular give is present in HF because of the Hydrogen bond present. Hydrogen bond is strong and will require much energy to break ,since no hydrogen bond is in the rest H2 and F2 has a low boiling point
Answer:
the oxidation state of each atom
