The rate of the reaction 2 A(g) + 3 B(g) + 5 C(g) →
is found to be independent of the concentration of A, first order in the concentration of B, and second order in the concentration of C. When 6.27 moles of A, 4.07 moles of B, and 6.8 moles of C are placed in a 2 liter container, the initial rate of the reaction is found to be 0.08 mol/liter·sec.
What is the numerical value of the reaction rate constant in units of moles, liters, and
seconds?
Answer in units of M−2· s−1.

i believe it is-

d.) gravity pulled particles of dust and gas together to form planets.

the ozone layer acts as a filter for the shorter wavelength and highly hazardous ultraviolet radiation (uvr) from the sun, protecting life on earth from its potentially harmful effects. when the sky is clear, there is an inverse relationship between stratospheric ozone and solar uvr measured at the earth's surface.

the answer is 1260

you spend 7 hours in school for 1 school day with 5 school days in 1 school week with 36 school weeks in a school year.

7*5*36= 1260 it's all about multiplying
