They are positive subatomic particles and are found in nucleus,
Answer:
N2O4
Explanation:
To obtain the molecular formula of the compound, first, let us calculate the empirical formula for the compound. This is illustrated below:
N = 0.606g
O = 1.390g
Next, we divide the above by their molar masses
N = 0.606/14 = 0.0432
O = 1.390/16 = 0.0869
Next, we divide by the smallest
N = 0.0432/0.0432 = 1
O = 0.0869/0.0432 = 2
The empirical formula is NO2
The molecular formula is given by:
[NO2]n = 92
[14 + (16x2)]n = 92
[14 +32]n = 92
46n = 92
Divide both side by the coefficient of n i.e 46
n = 92/46
n = 2
The molecular formula = [NO2]n = [NO2]2 = N2O4
Answer:
3.1 mol
Step-by-step explanation:
The balanced equation is
CaCl₂ + 2AgNO₃ ⟶ Ca(NO₃)₂ + 2AgCl
You want to convert moles of AgNO₃ to moles of CaCl₂.
The molar ratio is 2 mol AgNO₃:1 mol CaCl₂
Moles of CaCl₂ = 6.2 mol AgNO₃ × (1 mol CaCl₂/2 mol AgNO₃)
Moles of CaCl₂ = 3.1 mol CaCl₂
The reaction will require 3.1 mol of CaCl₂.
