Which statement describes what happens when somebody slaps their hand on a wall?

Chemistry
1 answer:
laiz [17]2 years ago
7 0

Answer:

B. Wall applies equal reaction force on hand

Explanation:

This is newton's third law. You push something, that something pushes you back with same force. The direction is opposite, so if I push a wall, the wall pushes me back with same force just in opposite direction (so wall towards me). This is why option A is incorrect b/c it says force in same direction as wall. C and D talk about unequal force which is incorrect.

Which term refers to a small group of atoms that are attached to larger molecules, providing them with specific chemical propert
stepan [7]
Answer: Small groups of atoms that are attached to larger molecules, giving the specific chemical properties, are called functional groups.

explanation: Functional groups are groups of atoms in a molecule that possess the same chemical feature every time it appears in several compounds. There are various types of functional groups and they have the tendency to react in definite ways. Examples include; the ether functional group (consists of an oxygen atom that forms single bonds with two carbon atoms),the alcohol functional group (consists of an oxygen atom that is bonded to one hydrogen atom and one carbon atom), and the amine functional group (consists of a nitrogen atom bonded to some combination of carbons and hydrogens).

No links please. How many moles of methane (CH4) are in 7.31x10^25 molecules?
ad-work [718]

Answer:

molar mass of methane CH4

= C + 4 H  

= 12.0 + 4 x 1.008

= 12.0 +  4.032

= 16.042g/mol

7.31 x 10^25 molecules x             1 mole  CH4      = 121.43 moles

                                      6.02 x 10^23 CH4 molecules

121.43 moles CH4 are present.

Explanation:

not to certain if this is right or not.. but hope it helps!

How is the number of unpaired valance electrons in an atom related to the number of bonds that the atom can form?
TiliK225 [7]
It is the same amount. For example, Carbon has 4 electrons. Putting those 4 electrons in a Lewis Dot Structure will show that they are not paired, so 4 is the number of bonds Carbon can make.
