Would you define boiling point and melting point as a periodic table family trend (vertical groups), period trend (horizontal rows), or neither? explain your answer.

i am so stumped on this question me out. it does not that my school did not give me a science book

What are the resulting coefficients when you balance the chemical equation for the combustion of ethane, c2h6? in this reaction, ethane is burned in the presence of oxygen (o2) to form carbon dioxide (co2) and water (h2o). (g)+(g)→(g)+(g)

Nitrogen (n), phosphorus (p), and potassium (k) are the main nutrients in plant fertilizers. according to an industry convention, the numbers on the label refer to the mass percents of n, p2o5, and k2o, in that order. calculate the n: p: k ratio of a 30: 10: 10 fertilizer in terms of moles of each element, and express it as x: y: 1.0.

Arrange the elements in order of increasing electronegativity. use the periodic table to you arrange the elements. p o k mg
