Answer:
See explanation and image attached
Explanation:
The addition of excess hydrogen to alkyne in the presence of a platinum catalyst leads to complete hydrogenation of the alkyne as shown in the image attached.
Therefore, an alkane is obtained as the major organic product when excess hydrogen reacts with an alkyne in the presence of a platinum catalyst.
Hello Mistyann!
First you need to know amount of barium phosphate is
Half of potassium phosphate, also 2.18 mol.
Molar mass of Barium phosphate is 3·137.2 + 2·(30.97+4·16) g/mol
You can calculate it yourself dear.
Now mass is amount of substance · molar mass.
It has been an honour to teach you, dear,
God bless!
Chemical Property(s):
Toxicity.
Reactivity.
Types of chemical bonds formed.
Coordination number.
Oxidation states.
Flammability.
Heat of combustion.
Enthalpy of formation.
I know these are chemical properties because they are all a result of a chemical change. Chemical changes change the form of an object. For example, diluting orange juice by adding water changes it's ph from an acid to almost neutral.
Hope this helps!

Answer:
Option (A) Each Zn atom loses 2 electrons, and each Co2+ ion gains 2
Explanation:
To know the right answer to the question, let us observe the changes in the oxidation number of Zn and Co. This is illustrated below:
Zn(s) + Co2+(aq) → Zn2+(aq) + Co(s)
The oxidation number of Zn changes from 0 to +2 indicating that Zn has lose 2 electrons.
The oxidation number of Co changes from +2 to 0 indicating that Co has gain 2 electrons.
Therefore, option A is the correct answer.
The answer is 1296.75 g
Molar mass of <span>Fe2(SO4)3 is the sum of atomic masses of its elements:
Mr(</span>Fe2(SO4)3) = 2Ar(Fe) + 3Ar(S) + 12Ar(O)
Ar(Fe) = 55.84 g/mol
Ar(S) = 32.06 g/mol
Ar(O) = 16 g/mol
Mr(Fe2(SO4)3) = 2 * 55.84 + 3 * 32.06 + 12 * 16
= 111.68 + 96.18 + 192
= 399.9 g/mol
Thus there are 399.9 g in 1 mol and x grams in 3.25 mol:
399 g : 1 mol = x : 3.25 mol
x = 399 g * 3.25 mol : 1 mol
x = 1296.75 g
