The subatomic particles that identifies an element and also represents its atomic number would be A. The number of protons.
The molecular formula shows the exact number of molecules. Therefor, the empirical formula is the simplest formula of the molecular formula
Using the answer from the first part, we know that 2.957 moles of bismuth have formed. Moreover, the molar ratio between bismuth and carbon monoxide is:
2 : 3
Using the method of ratios,
2 : 3
2.957 : CO
CO = (3 * 2.957) / 2
CO = 4.4355
4.436 moles of carbon monoxide will be formed
Answer:
Chemical change :has change in mass, heat is needed, new element is formed, hard to reverse.......
Physicalchange:does not have change in mass, heat is not necessary, no new element is formed, easy to reverse
what is it i don't get it means i don't understand
