Explanation:
Mass of the organic compound = 200g
Mass of carbon = 83.884g
Mass of hydrogen = 10.486g
Mass of oxygen = 18.640g
The mass of nitrogen = mass of organic compound - (mass of carbon + mass of hydrogen + mass of oxygen)
Mass of nitrogen = 200 - (83.884 + 10.486 + 18.64) = 200 - 113.01
Mass of nitrogen = 86.99g
The empirical formula of a compound is its simplest formula.

<u>Answer:</u> The heat required will be 58.604 kJ.
<u>Explanation:
</u>
To calculate the amount of heat required, we use the formula:
Q= heat gained or absorbed = ? J
m = mass of the substance = 100 g
c = heat capacity of water = 4.186 J/g ° C
Putting values in above equation, we get:
Q = 58604 Joules = 58.604 kJ (Conversion factor: 1 kJ = 1000J)
Thus, heat released by 100 grams of ice is 58.604kJ.
Answer:
Copper
Explanation:
copper is used in the wiring of the phone
The correct answer would be the first one. The reaction that will not conduct electricity would be CH3OH(l) = CH3OH(aq) since it stays as a single molecule in solution. It does not have any free electrons that will allow the flow of current into the solution. Other options dissociates into ions which has free electrons so they allow current to flow.
