Which compound has the same empirical and molecular formula ethyne ethene ethane methane?
Margaret [11]
Empirical formula is the simplest ratio of whole numbers of components in a compound 
molecular formula is the actual ratio of components in a compound .
the molecular formula for the compounds given are as follows
ethyne  - C₂H₂
ethene - C₂H₄
ethane - C₂H₆
methane - CH₄
the actual ratios of the elements                 simplified ratio
                     C : H                                           C : H
ethyne            2:2                                             1:1
ethene            2:4                                             1:2
ethane            2:6                                             1:3
methane         1:4                                             1:4
the only compound where the actual ratio is equal to the simplified ratio is methane 
therefore in methane molecular formula CH₄ is the same as empirical formula CH₄

Under the gold standard, a country in balance-of-trade equilibrium earns income from exports that is equal to the money its resi
solong [7]

The answer is true.

Explanation:

The balance of trade is nothing but the country's exports minus the country's imports.

Exports means, what you produce in the country and sell it to other countries, whereas imports means what you get or buy from the other countries.

When you export more than you import, you have trade surplus .In that case the income from exports are more than the money spent. So you have a trade surplus.

When you import then you have a trade deficit or your income is low. Most of the countries want a trade surplus.

But when the Income from exports and the money spent on imports are the same , the situation is that of balance of trade equilibrium, where the income from exports is equal to the money its residents pay for the imports.
