Does matter have weight and take up space?

Chemistry
1 answer:
miss Akunina [59]3 years ago
3 0

Explanation:

All matter has mass and occupies space. Volume is a measure of how much space an object occupies. ... "Mass" only depends on how much matter is in an object. "Weight", on the other hand, depends on how strongly gravity pulls on an object.

An ideal gas originally at 0.85 atm and 66°C was allowed to expand until its final volume, pressure and temperature were 94.0mL,
xeze [42]

Answer: The original volume in liters was 0.0707L

Explanation:

Combined gas law is the combination of Boyle's law, Charles's law and Gay-Lussac's law.

The combined gas equation is,

\frac{P_1V_1}{T_1}=\frac{P_2V_2}{T_2}

where,

P_1 = initial pressure of gas = 0.85 atm

P_2 = final pressure of gas = 456 mm Hg = 0.60 atm   (760mmHg=1atm)

V_1 = initial volume of gas = ?

V_2 = final volume of gas = 94.0 ml

T_1 = initial temperature of gas = 66^oC=273+66=339K

T_2 = final temperature of gas = 113^oF=318K  (32^0F=273K)

Now put all the given values in the above equation, we get:

\frac{0.85\times V_1}{339}=\frac{0.60\times 94.0}{318}

V_1=70.7ml=0.0707L   (1L=1000ml)

Thus the original volume in liters was 0.0707L

Verdadero o falso.
marusya05 [52]

Answer:

True

Ammonia reacts as a nucleophile with alkyl halides to give primary amines in a nucleophilic substitution reaction. Yields are often poor as the product, a primary amine, RNH2, is itself a nucleophile and can react with more alkyl

A nitrile is a compound that contains a –CN (cyano) functional group with a carbon-nitrogen triple bond. The simplest organic nitrile is CH3–CN and is called acetonitrile, which is a good solvent for organic reactions. ... Structurally diverse nitrile-containing compounds are present in many medicinal drugs.
