Answer : Option D) Silicates.
Explanation : The minerals with the silicon-oxygen structures are classified as silicates.
As per the definition, A silicate is any member of a family which has anions consisting of silicon and oxygen, usually they have the general formula as [SiO].
It usually has a structure which has a central silicon ion which has a charge of (+4) while each oxygen has a charge of negative two (-2) and thus each silicon-oxygen bond is equal to one half (1/2) of the total bond energy of oxygen. Therefore, it confirms that the answer is Silicates.
First we calculate the number
of moles of Cl2, that is:
moles Cl2 = 1.5*10^10
grams/71 grams/mol = 211267605.633802817 mol = 2.1 * 10 ^ 8 mole = x <span>
So that based on stoichiometry, the number of moles of NaOH =
2x and that of H2 = x mol
mass of NaOH = 4.2*10^8 * 40 =168*10^8 grams = 1.68 * 10^6 kg
= 1.68 metric tons
<span>mass of H2 = 2.1*10^8 * 2 = 4.2*10^8 grams = 0.042 * 10^6 kg
= 0.042 metric tons.</span></span>
Answer:
A
Explanation:
The lower mantle is under the surface of the earth while the ocieanic crust is above the surface
Answer:
the partial pressure of the O2 is 0.167 atm
Explanation:
The computation of the partial pressure of the O2 is shown below:
As we know that
P = P_N2 + P_O2 + P_CO2
P_O2 = P - P_N2 - P_CO2
= (1.007 - 0.79 - 0.05)
= 0.167 atm
Hence, the partial pressure of the O2 is 0.167 atm
we simply applied the above formula
