The Atomic Number.
-Hope this helps!
Answer and Explanation:
Iodine have lower atomic mass than tellurium even though the atomic number of iodine is more than the atomic number of tellurium
This is because the atomic weight of any element is the sum of number of proton and number of neutron, even though the number of proton in iodine is more so but the number of neutron is less as compared to tellurium which makes the tellurium of high atomic mass
Answer:
The Bowen's reaction series describes how minerals form in sequential order, forming at higher temperature to a lower temperature. There are two branches of crystallization, one is the continuous branch that is on the right and the other is the discontinuous branch that is on the left.
The minerals that are at the top of the Bowen's reaction series forms at a higher temperature.
In the discontinuous branch, the first mineral to crystallize from the melt is Olivine that forms at a higher temperature of about 1400°C. After crystallization, some melt remains and undergoes fractional crystallization leading to the formation of Pyroxene. Again, with the remaining melt, it reacts and forms Amphibole, followed by Biotite (mica).
In the continuous branch, the first minerals to form are the calcium-rich minerals and successively forms sodium-rich minerals. These minerals that form at a higher temperature are basic in nature and gradually change into acidic minerals.
From both the branches, it commonly forms the mineral Potassium feldspar. After this, the remaining melt combines with the magma and forms Muscovite (Mica), and at a temperature of about 650°C, it forms a more resistant and stable mineral known as the Quartz.
Answer:
0.0481 kg.
Explanation:
First, we need to find the volume of the room.
15 x 18 x 8 = 1350
The volume of the room is 1350 ft³
Now, we convert feet to centimeters
1350 x 30.48 = 41,148
The volume is 41,148 cm³
1 cm³ = 1 mL
So we can say that the volume of the room is also 41,148 mL
Then, we convert milliliters to liters
41,148 ÷ 1,000 = 41.148
There are 41.148 liters of air in the room
We multiply the air's density with volume in liters
41.148 x 1.168 = 48.060864
There are 48.060864 grams of air in the room
Finally, convert grams to kilograms
48.060864 ÷ 1,000 = 0.048060864
0.048060864 kilograms of air are in the room.
Explanation:
CH4+8/2Cl2—>CCl4+4HCl
that is,1molecule of methane+8/2 molecules of dichlorine—>1molecule of carbon tetrachloride+4molecules of hydrogen chloride
