Answer:
Mass = 12.48 g
Explanation:
Given data:
Mass of sulfur dioxide = 25.0 g
Mass of sulfur formed = ?
Solution:
Chemical equation:
SO₂ → S + O₂
Number of moles of SO₂:
Number of moles = mass/molar mass
Number of moles = 25.0 g / 64.07 g/mol
Number of moles = 0.39 mol
Now we will compare the moles of SO₂ with S.
SO₂ : S
1 : 1
0.39 : 0.39
Mass of sulfur:
Mass = number of moles × molar mass
Mass = 0.39 mol × 32 g/mol
Mass = 12.48 g
It is.
An acid will be strong when its conjugated base is highly stable, and vice-versa.
That can occur for instance through electronic delocalization.
D. Synthesis cause A + B --> AB
Equation: 2Na + Cl2 --> 2NaCl
<u>a) Answer: </u>
<em>Number of molecules in 1 mole</em>
<u>Explanation:</u>
a) Whether we take any of the substance among all three of the given substances they will have the same number of molecules in 1 mole of the substance is considered and the value for this will be 
<u>b) Answer: </u>
<em>In the given question </em><em>mass of the substance</em><em> which is </em><em>greatest</em><em> is asked for </em><em>one mole</em><em> and we also know that </em><em>mass of one mole is given by molar mass. </em>
<u>Explanation:</u>
b) It is known that
is the molar mass for oxygen which is greater than that of hydrogen while fluorine has a molar mass of
which on comparison shows that, it is the highest amongst all three.
Answer:
100g / (5.2g/cm3)
= 100g / (5.2g / 1cm3)
= 100g x 1cm3 / 5.2 g
= 19.2 cm3
Since 1 cm3 = 1 ml, your answer is 19.2 ml.
