# How does the law of conservation of mass apply to this reaction:

c2h4 + 3o2 โ 2h2o + 2co2 ?

the equation needs to be balanced.

there are fewer oxygen atoms in the equation than hydrogen or carbon. only

the oxygen needs to be balanced.

there are equal numbers of hydrogen and carbon. each element needs to be

balanced.

the law of conservation of mass has already been applied. there is an equal

number of each element on both sides of the equation.

In this problem, we explore the effect on the standard deviation of multiplying each data value in a data set by the same constant. consider the data set 14, 6, 8, 15, 15. (a) use the defining formula, the computation formula, or a calculator to compute s. (round your answer to one decimal place.) s = 4.28 (b) multiply each data value by 3 to obtain the new data set 42, 18, 24, 45, 45. compute s. (round your answer to one decimal place.) s = 12.83 (c) compare the results of parts (a) and (b). in general, how does the standard deviation change if each data value is multiplied by a constant c? multiplying each data value by the same constant c results in the standard deviation remaining the same. multiplying each data value by the same constant c results in the standard deviation being |c| times as large. multiplying each data value by the same constant c results in the standard deviation increasing by c units. multiplying each data value by the same constant c results in the standard deviation being |c| times smaller. (d) you recorded the weekly distances you bicycled in miles and computed the standard deviation to be s = 3.8 miles. your friend wants to know the standard deviation in kilometers. do you need to redo all the calculations? yes no given 1 mile รขโฐ 1.6 kilometers, what is the standard deviation in kilometers? (enter your answer to two decimal places.)
