Propane is C3H8
So Molar mass propane = 3*12 + 8*1 = 44 <span>
No. of moles of propane = 167/44 = 3.795 moles</span>
From the stoichiometry: <span>
No. of moles of hydrogen = 3.795 moles * (8 moles
hydrogen / 1 mole propane) = 30.36 moles
Using Avogadros number, 1 mole of any substance
contains 6.022 x 10^23 atoms, therefore:
<span>No. of hydrogen atoms = 30.36 * 6.022 x 10^23 =
1.828 x 10^25 atoms</span></span>
The best answer among the choices given that describes compression would be "<span>region of high pressure in a medium caused by a passing wave." The concepts of air compression is widely used in the industries such as vehicle tires, balloons, and other inflatable materials requiring high air pressure.</span>
Characteristics of pea plants are determined by genes inherited from both the parents.
Option 4.
<h3><u>Explanation:</u></h3>
Gregor Johann Mendel is also called as the father of Genetics. Mendel experimented on the pea plants to determine what happens when different types of pea plants are crossed between themselves and what actually determines the characteristics of the pea plants. After two types of experiments, he came to a conclusion that there are certain substances which he named as '' factors'' which are actually inherited from the parents. He also told that there are certain type of factors which are dominant over the others which he termed as recessive factors. So, the characteristics of the progenies depend on both the factors inherited from both the parents.
Answer:
6 moles of electrons
Explanation:
Let us consider the species NO3− and ClO−. The NO3− is oxidized to NO the oxidation number of nitrogen is decreased from +5 to +2.
The oxidation number of chlorine is increased from +1 to +3. This implies that six electrons were transferred in the balanced reaction equation shown in the question. Hence the answer.
