HELP! A merry-go-round of diameter 18 m revolves at a rate of 8.3 rev/min. What is the velocity of a child who is seated at the outer edge of the merry-go-round?

5.5 m/s
7.8 m/s
1.2 m/s
15.6 m/s

58750.08068 is the answer i think

the seeing the electronic configuration we can say that the element is fluorine.

fluorine is the most electronegative element in the periodic table.

but by only seeing the configuration we cannot say about its reactivity because we don't know if its configuration after excitation or by addition of electrons.

but if not then, it is the lightest halogen and exists as a highly toxic pale yellow diatomic gas at standard conditions. as the most electronegative element, it is extremely reactive: almost all other elements, including some noble gases, form compounds with fluorine.

the equation for synthesis of water is as follows;

here two moles of hydrogen are used with one mole of oxygen which gives one molecule of water as a product. but shana misinterpreted 2 moles as 2 grams in this equation.
