Answer:
4.952 × 10^28 atoms
Explanation:
1. Atoms in one molecule of glucose
The formula for glucose is C6H12O6.
In one molecule of glucose there are
6 + 12 + 6 = 24 atoms
2. Molecules of glucose
Molecules = 6853 mol × (6.022 × 10^23 molecules/1 mol)
= 4.1269 × 10^27 molecules
3. Atoms
Atoms = 4.1269 × 10^27 molecules × (12 atoms/1 molecule)
= 4.952 × 10^28 atoms
There are 4.952 × 10^28 atoms in 6853 mol of glucose
Hey there!:
Number of moles = 3.33 moles of neon
Volume = 13.4 L
Pressure = 3 atm
R = 0.0821 L.atm/mol*K
Therefore:
T = 3.0 * 13.4 / 3.33 * 0.0821
T = 40.2 / 0.2734
T = 147 K
k in C :
ºC = K - 273
147 - 273
T = - 126ºC
Hope that helps!
Hydrogen Bromide or Hydrobromic acid having the formula HBr is the <span>binary compound that decomposes to the products H2 and Br2. This can be represented as
2HBr ----> H2 + Br2
I hope that this is the answer that you were looking for and it has actually come to your desired help.</span>
Answer:
High
Explanation:
When the unknown compound contains an impurity that is insoluble in cyclohexane, the solute will not dissolve in the solvent (cyclohexane) completely. ∆T of the solution would be smaller than it is supposed to be, when compared to a compound without such insoluble impurity. Molecular weight determination won't be accurate because the molecular weight obtained will be higher as a result of the fact that the mass of the solute would include the actual solute that is changing the temperature and the excess mass of the impurity.
Answer:
Same number of valance electrons
Explanation:
All of them are in group 1 so they have 1 valance electron.
If they were in same period they would have same number of energy levels.
