Formation of nitric oxide is a highly exothermic reaction
methanol:
1 mole CH3 OH --> produces --> 1 mole CO2
1 mole CO2 has a molar mass of 44.01 gh/mole
your set up is:
(44.01 g CO2) / -726.5kJ = 0.06058g
your answer 0.06058 grams of CO2 produced per kJ released.
Explanation:
in this question, we're asked how to determine whether we have a metallic or nonmetallic substance.So what you want to do is one to remember that metals are malleable and Nonmetal are brittle. So if we were to hammer the metal, it would be very malleable, but the nonmetal would fall apart. And never we could just hammer the sample and see whether it was malleable. And therefore it would be a medal or a brittle and therefore being nonmetal.

Explanation:
In the classification of organisms, they are placed into groups which they appropriately fit into.
All the choices given correctly shows the process of classifying organisms. This aspect of biology is described as taxonomy.
- Based on characteristics of organisms, they are put into the same groups
- Also, we can identify the related family and genus in which a discovered organism can be put into.
- They phylogenetic relationship between organisms are important for classification.
