Answer:
6.50 g of Hydrogen
Explanation:
We know that in every 20.0g of sucrose, there are 1.30g of hydrogen.
We now have 100.0g of sucrose. 100.0g is 5x larger than the 20.0g sample, which is a 5 : 1 ratio. Applying this ratio to the amount of hydrogen, we would have 5*1.3g of hydrogen in the 100.0g of sucrose.
5*1.3 = 6.5, so our answer is that there are 6.50g of hydrogen in 100.0g of sucrose.
Hope this helps!

<h3>Known</h3>
Mass = 32grams
Name of atom = Methane (CH4)
Molar mass C = 12
Molar mass H = 1
════════════════════
<h3>Question</h3>
molecules (mol?)
════════════════════
<h3>Way to do</h3>
mass = mol × molar mass
32g = mol × (CH4)
33g = mol × (12 + (4×1))
32g = mol × 16
mol = 32 : 16
mol = 2

Answer:
The rate of gas diffusion is directly proportional to temperature
Explanation:
The rate of gas diffusion is
a) directly proportional to square root of temperature
b) inversely proportional to the square root of density
c) directly proportional to pressure
d) inversely proportional time and square root of molecular mass
Thus, option A is correct
The answer is so it didn't burn.
Strong acid on combining with strong base will always give neutral solutions. Consider the following example for the same
HCl + NaOH ↔ NaCl + H2O
(strong (strong
acid) base)
In above case, the resultant solution is neutral in nature.
On other hand, weak acid will react with strong base to form salt and water. But the solution will be basic in nature. Also, strong acid will react with weak base to form salt and water. But the solution will be acidic in nature
