Refer to the following balanced equation in which
ammonia reacts with nitrogen monoxide to produce
nitrogen and water.
4nh3(8) + 6no(g) → 5n2(g) + 6h2o(1)
how many moles of no are required to completely
react with 2.45 mol nhz?
mol no
your answer should be rounded to three significant figures. do not
include units in your answer.

answer is c

explanation:

cant without the picture! ?

see the picture for the vector

the magnitude of the vector by pythagorean theorem

r = √( (-10)^2 + (3)^2 ) = √109

magnitude = √109 units

the direction angle between vector and x-axis is

tan^(-1)(3/10) = 16.699

so the direction is approximately 16.7 degrees north of west

find the surface area of the sphere to the nearest square unit. use a calculator.
