Answer:
2H2+O2->2H2O
Explanation:
You have to balance the equation, you have 4 hydrogen and 2 oxygen atoms
Answer:
14.8 × 10²³ molecules
Explanation:
Given data:
Mass of sulfuric acid = 240 g
Number of molecules = ?
Solution:
The given problem will solve by using Avogadro number.
It is the number of atoms , ions and molecules in one gram atom of element, one gram molecules of compound and one gram ions of a substance.
The number 6.022 × 10²³ is called Avogadro number.
For example,
18 g of water = 1 mole = 6.022 × 10²³ molecules of water
1.008 g of hydrogen = 1 mole = 6.022 × 10²³ atoms of hydrogen
Number of moles of sulfuric acid
<em>Number of moles = mass/ molar mass</em>
Number of moles = 240 g/ 98 g/mol
Number of moles = 2.45 mol
Number of molecules:
1 mole = 6.022 × 10²³ molecules
2.45 × 6.022 × 10²³ molecules
14.8 × 10²³ molecules
Answer:
a) Order of a reaction is always a whole number
Explanation:
Order of a reaction is not always whole number. It can be zero, or fractional .
Explanation:
NH4OH(aq) ---> NH4+(aq) + OH-(aq)
Part of the answer you are looking for may be- Molecules overcome attractions easily and at high temperatures, move faster- (paraphrased from Google) Since the question asked was not provided with the statements as proposed in the original question, I cannot give you an exact answer. I did what i could do, hope this helps!
