Answer:
5.72 moles of nitrogen oxide are formed when 2.86 moles of nitrogen react.
Explanation:
Given data:
Moles of NO formed = ?
Moles of N₂ reacts = 2.86 mol
Solution:
Chemical equation:
N₂ + O₂ → 2NO
Now we will compare the moles of nitrogen with nitrogen oxide from balance chemical equation.
N₂ : NO
1 : 2
2.86 : 2/1×2.86 = 5.72 mol
So 5.72 moles of nitrogen oxide are formed when 2.86 moles of nitrogen react.
Answer:
0.022
Explanation:
milliter (ml) = 1 cubic centimeter (cc)= 0.001 liters (l) = 0.000001 cubic meters (m3).
1 ml = 0.061024 cubic inches (in3) ; 1 in3 = 16.4 ml.
1 ml = 0.000035 cubic feet (ft3); 1 ft3 = 28,317 ml.
1 ml = 2.64 x 10-4 U.S. gallons (gal); 1 gal = 4.55 x 103 ml.
<h3>Answer:</h3>
False: Isotopes have variable number of Neutrons.
<h3>Explanation:</h3>
Isotopes are defined as those atoms of same element which have same number of protons but different number of neutrons hence, isotopes have different number of neutrons and mass number respectively.
Example:
Hydrogen have three Isotopes;
i) Protium-1 having 0 neutrons
ii) Deuterium-2 having 1 neutron
iii) Tritium-3 having 2 neutrons
While, when the number of electrons for a particular atom varies it results in the formation of ions of that atom.
Example:
Hydrogen when looses one electron it converts into H⁺
Nitrogen when gains three electrons it converts into N⁻³
Chlorine when gains one electrons it converts into Cl⁻
Magnesium when looses two electrons it converts into Mg⁺⁺
