ycow [4]3 years ago
5 0

Answer:

<u>c) More force has to be used to lift the heavier sack.</u>

Explanation:

Using more force to lift the heavy sack of rice makes you really tired. Thus it's harder to lift a 100 pound sack of rice than to lift a 5 pound bag of sugar.

The group of atoms that is responsible for the characteristic properties of a family of organic compounds is called a/an _______
Sindrei [870]

The group of atoms that is responsible for the characteristic properties of a family of organic compounds is called a <u>functional</u> group.

Functional groups are groups of one or extra atoms with exclusive chemical homes regardless of what's connected to them. The atoms of practical agencies are certain via covalent bonds with one another and with the relaxation of the molecule.

Functional groups include:

  • hydroxyl,
  • methyl,
  • carbonyl,
  • carboxyl,
  • amino, phosphate,
  • sulfhydryl.

An atom or institution of atoms that replaces hydrogen in a natural compound that defines the shape of a family of compounds and determines the properties of the family.

1 mole of no2(g) has a greater entropy than 1 mole of n2o4(g). true or false
bija089 [108]
In order to answer this, you need to find the empirical data for the standard entropies. Please refer to this link: http://www.mrbigler.com/misc/energy-of-formation.PDF

For NO₂ gas, the entropy is 240 J/mol-K. For N₂O₄ gas, the entropy is 304.2 J/mol-K. Therefore, <em>the statement is false.</em>

) Experimental evidence indicates that the nucleus of an atom
geniusboy [140]

Answer:

A (contains most of the mass of the atom)

Evidence has it that a proton is about 2000 times as massive as an electron.

And there is usually multiple protons and neutrons in the nucleus

From what I just said, you can say that B is wrong

C however is also wrong because protons have a +charge and neutrons are neutrle which means you always have a charge > (greater than) 0

And D is wrong because electrons (which are not in the nucleus) have a neg charge. and protons have a + charge and are in the nucleus

So your answer is A

Hope it helped

the average kinetic energy of the particles in a gas increases as the temperature of the gas increases. explain​
sveticcg [70]

Answer:

Explanation: Volume versus Temperature: Raising the temperature of a gas increases the average kinetic energy and therefore the rms speed (and the average speed) of the gas molecules. Hence as the temperature increases, the molecules collide with the walls of their containers more frequently and with greater force.
