Explanation:
just trust me Im a 8th grader and I did that before
Explanation:
Mass of solution , m= 0.94 g + 215 g = 215.94 g
Volume of the solution = V
Density of solution = d =
Moles of hydrogen =
Molarity of hydrogen gas:
Molality of hydrogen gas :
Mass of solvent or here it is palladium = 215 g =0.215 kg (1 g = 0.001 kg)
Mass percentage of hydrogen is solution :
Answer:
A Brønsted-Lowry acid.
A Brønsted-Lowry base.
Ammonia is an acceptor of proton.
Explanation:
A Brønsted-Lowry acid is any atom that can donate a proton (H +) to another atom or molecule whereas Brønsted-Lowry base is any species that can accept a proton from another atom or molecule or in other words, a Brønsted-Lowry acid is a proton donor, while on the other hand, a Brønsted-Lowry base is a proton acceptor. The ammonia molecule accepts the hydrogen ion is considered as the Brønsted-Lowry base.
Answer:
B.
Explanation:
Some of the elements of the third-period and periods below can have expanded octet because they have d- sub-level.
We have 2 possible answers. A and B. Because lodine and chlorine. Sulfur and phosphorous are in the 3d or lower periods.
In the compound P2S5, where P forms 5 bonds.
Iodine and chlorine do not have enough difference in electronegativity to form compound ICl7.
So, the answer is B.
Answer:
Explanation:
Hydrocholoric acid is written as HCl
Calcium carbonate is written as
For a balanced equation, 2 moles of Hydrochloric acid reacts with 1 mole of calcium carbonate to give one mole of calcium chloride, 1 mole of carbon dioxide and 1 mole of water respectively.
Baking soda is written as
Vinegar is written as
1 mole of vinegar reacts with 1 mole of baking soda to give 1 mole of sodium acetate, one mole of carbon dioxide and 1 mole of water respectively.
