Answer: 66.2 g
Explanation:
1) The ratio of Al in the molecule is 1 mol to 1 mol .
2) The mass of 1 mol of molecules of Al (CH2H3O2)3 is the molar mass of the compound.
3) You calculate the molar mass of the compound using the atomic masses of each atom, in this way:
Al: 27 g/mol
C: 2 * 3 * 12 g/mol = 72 g/mol
H: 3 * 3 * 1 g/mol = 9 g/mol
O: 2 * 3 * 16 g/mol = 96 g/mol
Molar mass = 27 g/mol + 72 g/mol + 9 g/mol + 96 g/mol = 204 g/mol
4) Set a proportion:
27 g/mol x
-------------------- = ----------
204 g/mol 500 g
5) Solve for x:
x = 500 g * 27 g/mol / 204 g/mol = 66.2 g
Answer: 0.002 M
Explanation:
The balanced chemical equation for ionization of in water is:
According to stoichiometry :
1 mole of ionizes to give =2 mole of ions
0.001 mole of ionizes to give = mole of ions
Thus of a solution of 0.001 M aqueous sulfuric acid is 0.002 M
Answer:
The answer is ""
Explanation:
When is added in the chemical equation it reacts with sodium acetate so, it will give the following chemical equation:
In this, the is a weak acid so, it not completely dissociated.
were strong electrolytes they are completely dissociated.
The is a strong acid so, it is completely dissociated So, the net ionic equation is:
Among the choices, the only one that can be considered a carnivore is C. Adelie penguin. Adelie penguins are found in the Arctic, and feed on aquatic creatures such as krill, fish, and squid. Krill is a type of crustacean that feeds on phytoplankton, which is at the bottom of the food chain.
