Answer:
carbon dioxide and water.
Explanation:
Chemical equation:
2C₂H₆ + 7O₂ → 4CO₂ + 6H₂O
Reactants are present on the left side of chemical equation while products are present on the right side of chemical equation. In given chemical equation ethane and oxygen are reactant while carbon dioxide and water are product.
The given reaction is combustion reaction. Ethane is burnt in the presence of oxygen and produces carbon dioxide and water.
The reaction also follow the law of conservation of mass.
This law was given by French chemist Antoine Lavoisier in 1789. According to this law mass of reactant and mass of product must be equal, because masses are not created or destroyed in a chemical reaction.
Answer: Crystals differ in physical properties, i.e., in hardness, cleavage, optical properties, heat conductivity, and electrical conductivity.
These properties are important since they sometimes determine the use to which the crystals are put in industry.
hope this helps :)
Answer:
None of these answers are correct.
CO2 is a covalent not ionic compound
It DOES melt, though at a very low temperature
Its melting point is negative, not high
Explanation:
Cr^2+ + H2MoO4 + H+ → Cr^3+ + Mo + H2O
Cr goes from +2 to +3 or loses one e-
Mo is +6 in H2MoO4 so it goes to 0 gaining 6 e-
so we must multiply Cr by 6 to balance e-
6Cr^2+ + H2MoO4 + H+ → 6Cr^3+ + Mo + H2O
now we balance the spectators
take O first - 4 on left then, change the right side
6Cr^2+ + H2MoO4 + H+ → 6Cr^3+ + Mo + 4H2O
now we have 8 H's on the right
we don't want to touch the H2MoO4
so we make H+ up to 6 for a total of 8 on the left
6Cr^2+ + H2MoO4 + 6H+ → 6Cr^3+ + Mo + 4H2O
Then, It's balanced
