Answer:
K2SO4, NH3, HOCI, HCI, CH3NH2, SiCl4, CO2, CH20
Explanation:
Substances are soluble in water when they are ionic or polar covalent substances.
If we look at the substances listed, K2SO4 is ionic while NH3, HOCI, HCI, CH3NH2, SiCl4, CO2, CH20 all contain polar covalent bonds which accounts for their water solubility.
Hence ionic and polar covalent substances are soluble in a polar solvent such as water.
Explanation:
electrovalent bond covers single bond.
Covalent bond covers double or more bonds.
Answer:The answer to this question comes from experiments done by the scientist Robert Boyle in an effort to improve air pumps. In the 1600's, Boyle measured the volumes of gases at different pressures. Boyle found that when the pressure of gas at a constant temperature is increased, the volume of the gas decreases. when the pressure of gas is decreased, the volume increases. this relationship between pressure and volume is called Boyle's law.
Explanation: So, at constant temperature, the answer to your answer is: the volume decreases in the same ratio as the ratio of pressure increases.
BUT, in general, there is not a single answer to your question. It depend by the context.
For example, if you put the gas in a rigid steel tank (volume is constant), you can heat the gas, so provoking a pressure increase. But you won't get any change in volume.
Or, if you heat the gas in a partially elastic vessel (as a tire or a soccer ball) you will get both an increase of volume AND an increase of pressure.
FINALLY if you inflate a bubblegum ball, the volume will be increased without any change in pressure and temperature, because you have increased the NUMBER of molecules in the balloon.
There are many other ways to change volume and pressure of a gas that are different from the Boyle experiment.
Answer: There is no question, but we can calculate a couple of items:
Density of sea water sample = (52.987g-44.317g)/8.5ml
Inorganic content of sample (mostly salts) = (44.599g-44.317g)/(52.987g-44.317g) x 100% = percent inorganics in water sample
Explanation:
C2H6 is a chemical compound
