Answer:
See explanation
Explanation:
The magnitude of electronegativity difference between atoms in a bond determines whether that bond will be polar or not.
If the electronegativity difference between atoms in a bond is about 1.7, the bond is ionic. If the electronegativity difference is greater than 0.4 and less than 1.7, the bond will have a polar covalent character. Lastly, if the electronegativity difference between the bond is less than or equal to 0.4, the covalent bond is non polar.
The electronegativity difference between carbon and hydrogen is about 0.4 which corresponds to a nonpolar covalent bond hence the molecule is nonpolar.
The electronegativity difference between carbon and fluorine is about 1.5 indicating a highly polar bond. This gives CH3F an overall dipole moment thereby making the molecule polar.
Molar mass H₂O = 18.0 g/mol and O₂ = 32.0 g/mol
2 H₂O --------> O₂ + H₂
(2* 18.0 g ) H₂O ----------> 32 g O₂
72.0 g H₂O ----------------> ?
mass of O₂ = 72.0 * 32 / 36
mass of O₂ = 2304 / 36
= 64 g of O₂
hope this helps!
Answer:
7.2 gm or 0.0072 Kg
Explanation:
Let k be the kg of packets that are to be used.
36 X 200 mg = 1000 X k
=> k = 7.2 gm.
Answer:
The correct answer is 0.50 mol (NH₄)₃PO₄
Explanation:
The balanced chemical equation between liquid ammonia (NH₃) and H₃PO₄ is the following:
3 NH₃ + H₃PO₄ → (NH₄)₃PO₄
According to the equation, 3 mol of ammonia produce 1 mol of ammonium phosphate. Thus, the stoichiometric ratio is 1 mol (NH₄)₃PO₄/3 NH₃. To calculate the moles of (NH₄)₃PO₄, we multiply the ratio by 1.50 mol NH₃:
1.50 mol NH₃ x 1 mol (NH₄)₃PO₄/3 NH₃ = 0.50 mol (NH₄)₃PO₄
