Methane is lighter than air, having a specific gravity of 0.554. It is only slightly soluble in water. It burns readily in air, forming carbon dioxide
and water vapour; the flame is pale, slightly luminous, and very hot.
The boiling point of methane is −162 °C (−259.6 °F) and the melting
point is −182.5 °C (−296.5 °F). Methane in general is very stable, but
mixtures of methane and air, with the methane content between 5 and 14
percent by volume, are explosive. Explosions of such mixtures have been
frequent in coal mines and collieries and have been the cause of many
mine disasters.
Answer:
not sure, but you know what?
Explanation:
you are amazing! keep doing what youre doing!
Answer:
a. NH3+ HCl → NH4Cl
c. 2O3 → 3O2
Explanation:
A redox reaction is a reaction in which there is loss or gain of electrons. As a result of that , there is a change in the oxidation number of the species involved in the reaction.
If we look at the species shown in the answer, there isn't any change in oxidation number as we move from left to right hence they are not redox reactions.
Redox reactions lead to change in oxidation number of species from left to right.
1) The amount of PbS produced will be 16.27 grams
2: The amount of Fe produced will be 118.72 grams.
<h3>Stoichiometric problems</h3>
1) The equation is balanced. The mole ratio of lead (II) acetate to the PbS is 1:1.
Mole of 22.11 lead acetate = 22.11/ 325.29 = 0.06797 moles
Equivalent mole of PbS = 0.06797 moles
Mass of PbS = 0.06797 x 239.3 = 16.27 grams
2) from the equation, the mole ratio of Al to Fe is 1:1.
Mole of 57.2 g Al = 57.2/26.98 = 2.12 moles
Equivalent mole of Fe = 2.12 moles
Mass of Fe = 2.12 x 56 = 118.72 grams.
