Ithink the answer is b, but i just looked it up, so yeah. i need a real answer, no guessing the speed of sound is typically measured in: a. cm/sec b. m/sec c. km/sec d. mi/sec e. mi/minps- why is there no science

In a reaction (at equilibrium) that makes more moles of gas than it consumes, what is the effect of increasing the pressure?

The reactions shown here can be combined to make the overall reaction c(s) + h2o(g) ⇌ co(g) + h2(g) by reversing some and/or dividing all the coefficients by a number. a. c(s) + o2(g) → co2(g) k=1.363×10^69 b. 2 h2(g) + o2(g) → 2 h2o(g) k=1.389×10^80 c. 2co(g) + o2 (g) → 2 co2(g) k=1.477×10^90

Adeuteron, 21h, is the nucleus of a hydrogen isotope and consists of one proton and one neutron. the plasma of deuterons in a nuclear fusion reactor must be heated to about 3.02×108 k . what is the rms speed of the deuterons? express your answer using two significant figures.
