Answer:
M(AgNO3) = 169,8731 g mol
Explanation:
M(Ag) = 107,8682 g mol
M(N) = 14.0067 g mol
M(O) = 15.9994 g mol
M(AgNO3) = M(Ag) + M(N) + 3 x M(O) = 107.8682 + 14.0067 + 3 x 15.9994 =
= 169,8731 g mol
Just sum up all the respective elements' molar mass.
Acids
Vinegar (Acetic Acid)
Lemon juice (Citric Acid)
Orange Juice (Citric Acid)
Soda (Carbonic acid)
Asprin (Acetylsalicylic acid)
Bases
Bleach ( sodium hypochlorite)
Drain Cleaner (sodium hydroxide)
Baking Soda (sodium bicarbonate)
Baking Powder (sodium carbonate)
Windex (ammonia)
Answer:
21 molecules of oxygen.
Explanation:
The balanced equation is
2CH3CH2COOH + 7O2 -----> 6CO2 + 6H2O.
So 2 molecules of propanoic acid require 7 moles of oxygen.
Therefore 6 molecules require 7/2 * 6 = 21 molecules of oxygen.
Answer:
See explanation
Explanation:
In looking at molecules to determine whether they are polar or not we have to look at two things basically;
i) presence of polar bonds
ii) geometry of the molecule
Now, we know that CCI2F2 is a tetrahedral molecule, but the molecule is not symmetrical. It has four polar bonds that are not all the same hence the molecule is polar.
In an electric field, polar molecules orient themselves in such a way that the positive ends of the molecule are being attracted to the negative plate while the negative ends of the molecules are attracted to the positive plate.
So the positive ends of CCI2F2 are oriented towards the negative plate of the field while the negative ends of CCI2F2 are oriented towards the positive ends of the field.
