What two things must you specify when describing the velocity of an object

Chemistry
1 answer:
kati45 [8]4 years ago
5 0

When describing the velocity of an object, you must specify the both the speed and the direction.

That’s because <em>velocity is a vector</em>: it has both magnitude (speed) and direction.

If you say that a object is travelling southwest at 70 km/s, you are giving its velocity.

If you say that it is travelling at 70 km/s, you are giving its speed.

Copper + silver nitrate → copper(II) nitrate + silver<br> (convert to formula)
kiruha [24]

Answer:

Cu(s)+2AgNo^3(ag) \rightarrow Cu(No)_3^2(aq)+2Ag(s)

Explanation:

The given reaction has been occurred when the copper being more reactive than that of the silver. Which will subsequently displace the silver cations present in it, (by reducing it to the elemental metal). Copper being itself will get oxidized to the copper (II) cation forming Cu^{2+} and dissolve in the solution. So, the final product formed with the silver metal will start precipitation out and giving the copper (II)  nitrate as resultant in the solution.

When 2,2-dimethylbutane is subjected to free-radical chlorination, ________ distinct monochlorinated products are possible and _
malfutka [58]

Answer:

See the explanation

Explanation:

In this case, we have to remember that in the <u>monochlorination products</u> we only have to add one "Cl" with this in mind, we can have several options.

<u>a) 1-chloro-2,2-dimethylbutane</u>

<u>b) (R)-3-chloro-2,2-dimethylbutane</u>

<u>c) (S)-3-chloro-2,2-dimethylbutane</u>

<u>d) 1-chloro-3,3-dimethylbutane</u>

Additionally, from these 4 molecules, we will have 2 enantiomers. (R)-3-chloro-2,2-dimethylbutane and (S)-3-chloro-2,2-dimethylbutane.

See figure 1

THIS IS SO IMPORTANT PLEASE HELP!
jeka94
Protons: 12
Neutrons: 12
<span>Electrons: 12

The atomic number of Magnesium is 12, so it has to have 12 protons. The atomic mass of Magnesium is 24, so it has to have 12 neutrons since 12+12=24 (electrons don't have weight). You can tell it has 12 electrons because the electrons are always the same number as the protons.</span>
