Heat= mass * change in temperature* specific heat
specific heat=409 J/kg K
When the element is reduced it gains electrons, maybe it's charge becomes more negative.
the unnamed spacecraft which travels to Mars, will have the greatest weight on the Earth.
An iconic compound is the highest occupied energy level of an atom so your answer would be....... B
Answer:
Carbon has the highest mass percent
Explanation:
Step 1: Data given
Predict the element that will have the highest mass percent composition in each compound without doing any calculations.
For C3H6O, carbon will have the highest mass percent. The molar mass of of Oxygen and carbon are more or less the same. But we have 3x more Carbon than oxygen.
Identify the element that has the highest mass percent composition in C3H6O .
atomic mass C = 12.01 g/mol
atomic mass O = 16.0 g/mol
atomic mass H = 1.01 g/mol
molar mass C3H6O = 58.08 g/mol
%C = (3*12.01 / 58.08) * 100 %
%C = 62.04%
%O = (15.99 /58.08) *100%
%O = 27.53 %
%H = (6*1.01 / 58.08) * 100%
%H = 10.43
Carbon has the highest mass percent
