Pluto was ruled not a planet anymore because it is a "dwarf planet"
Apparently, the International Astronomical Union's (IAU) definition of a planet includes that a planet should be part of a body that would orbit the sun.
According to the IAU, there are three criteria's that contribute to a planet being called a planet.
1. It is within orbit around the Sun.
2. It has a sufficient mass to assume a nearly round shape
and 3. It has "cleared the neighborhood" around it's orbit.
Pluto only so happens to meet 2 of these requirements, not including the third option.
There are 3 atoms found in one molecules of
Answer:
The answer is
<h2>5.50</h2>
Explanation:
The volume of a substance when given the density and mass can be found by using the formula
From the question
mass = 22 g
density = 4 g/mL
The volume is
We have the final answer as
<h3>5.50 mL</h3>
Hope this helps you
Answer:
Answer in explanation
Explanation:
In the first case, we divide each of the masses by the respective atomic masses:
N =0.615/14 = 0.043928571428571
O = 0.703/16 = 0.0439375
It can be seen here that the values are similar, hence the formula is NO
now let us look at the second data set:
N = 1.27/14 = 0.090714285714286
O = 2.9/16 = 0.18125
We now divide by the smallest
N = 090714285714286/090714285714286 = 1
O = 0.18125/090714285714286 = 2
The formula here is thus NO2.
It can be seen that there are different oxides of nitrogen here which clearly indicates the law of multiple proportion.
