Answer:
10.
Explanation:
We need 10 question to separate ten arthropods into different branches because each arthropod belongs to separate branch and each branch needs explanation. Phylum Arthropoda is considered as the largest phylum in the animal world, and insects form the largest class within this phylum due to its highest number of individual or organisms. Each arthropods are different from one another so they needs more questions to separate them from each other.
<u>Answer:</u> The net chemical equation is given below.
<u>Explanation:</u>
To determine the net chemical equation, we will look into the intermediate steps:
<u>Step 1:</u> Formation of ammonia from hydrogen and nitrogen gas.
......(1)
<u>Step 2:</u> Formation of nitric acid from ammonia and oxygen gas.
.....(2)
The net chemical equation for the formation of nitric acid from hydrogen gas, nitrogen gas and oxygen gas follows by adding both the equations, we get:
By Stoichiometry of the reaction:
1 mole of hydrogen gas reacts with 2 moles of oxygen gas and 3 moles of hydrogen gas to produce 1 mole of nitric acid, 1 mole of water and 1 mole of ammonia.
Hence, the net chemical equation is given below.
Which ancient Greek philosopher was the focus of study for the Italian humanists?
ANS : Aristotle
Answer:
Hydrogen, H_2
Explanation:
mass of each gas is 10.0 g
number of mole = mass/ molar mass
number of moles is directly proportional to volume at constant temp and pressure
this implies that the volume is inversely proportional to molar mass. And Among all the gases in periodic table the molar mass of Hydrogen is the least.
molar mass of H2=2 g/mol
Since, H2 has minimum molar mass then for the same mass of the gases Hydrogen will have maximum volume.
