Acertain compound of bromine and fluorine is used to make uf6, which is an important chemical in the processing and reprocessing of nuclear fuel. the compound contains 58.37 mass percent bromine. what is its empirical formula
a. brfb. brf2c. br2f3d. br3fe. brf3

2 k(s) + br2(g) ? 2 kbr(s) a. 1.46 mol b. 1.78 mol c. 2.92 mol d. 3.56 mol e. 5.84 mol

i think the answer is the second one

the answer to your question would be a. angle at which the ray strikes the medium

answer : the length of the ramp to the nearest inch will be, 129.49

step by step explanation :

as we know that,

in the given image, the value of (the angle between the base and the hypotaneous) is and the value of perpendicular is 18 inch.

now we have to calculate the value of the hypotaneous by using above expression, we get

the hypotaneous is equal to the length of the ramp = 129.49 inch

therefore, the length of the ramp to the nearest inch will be, 129.49
