Ammonium sulfide
68,154 g/mol
41.10 percent nitrogen, 11.83 percent hydrogen, and 47.04 percent sulfur.
Sodium because according to the atomic size trend of the periodic table. Elements further to the left are bigger while elements tot he right are smaller. This is also do to their charges, Na has a +1 charge meaning it doesn’t pull the electrons as close as the Mg does with its +2 charge.
Answer:
When comparing propionic acid (CH₃CH₂COOH) and sodium propionate (CH₃CH₂COONa), the one that is more soluble in water sodium propionate.
When comparing cyclohexane (C6H12) and glucose (C6H12O6), the one that is more soluble in water is glucose
When comparing hydrochloric acid (HCl) and ethyl chloride (CH3CH2Cl), the one that is more soluble in water is hydrochloric acid
Explanation:
When comparing propionic acid (CH₃CH₂COOH) and sodium propionate (CH₃CH₂COONa), the one that is more soluble in water sodium propionate. Because always a salt is more soluble in water than its acid (Solubility of propionic acid is 0,37g/mL and of sodium propionate is 1g/mL).
When comparing cyclohexane (C6H12) and glucose (C6H12O6), the one that is more soluble in water is glucose because cyclohexane is made from petroleum and its polarity is very low (cyclohexane is insoluble in water and solubility of glucose is 0,91g/mL).
When comparing hydrochloric acid (HCl) and ethyl chloride (CH3CH2Cl), the one that is more soluble in water is hydrochloric acid because an acid has a medium-high solubility in water but, again, an alkane derived from petroleum has very low solubility in water (hydrochloric acid has a solubility of 0,823g/mL and ethyl chloride is insoluble in water).
I hope it helps!
Answer:
To my knowledge, it should be the last 2
Explanation:
1. Incorrect as atoms make up elements when they all have the same properties
2. Incorrect, an element can have other similar elements, they're ordered like that in the periodic table
3. Correct as atoms are made up of mostly space, with mass concentrated at the center of the atom, the nucleus and a few tiny electrons in orbit as proved by Rutherfords alpha particle scattering experiment
4. Correct, Atoms are known as the building blocks of matter
