CO(g)+2H2(g)>CH3OH(g)The synthesis of CH_3OH(g) from CO(g) and H_2(g) is represented by the equation above. The value of K_c for the reaction at 483 K is 14.5 Which of the following explains the effect on the equilibrium constant, K_c, when the temperature of the reaction system is increased to 650 K? (A) K_c will increase because the activation energy of the forward reaction increases more than that of the reverse reaction.. (B) K_c will increase because there are more reactant molecules than product molecules .(C) K_c will decrease because the reaction is exothermic. (D) K_c is constant and will not change.

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 303.15 or 303

nacl or sodium chloride is an ionic compound. this is because an ionic compound pertains to a compound that consists of positively and negatively charged ions. in this case, na (sodium) has a tendency to lose one electron when it reacts with with other atoms, so the resulting sodium ion contains 11 protons and 10 electrons, thus making it positively charged (na+), when chlorine reacts, it usually gains one electron to form an ion called chloride, thus making it negatively charged ( since the ions are oppositely charged, they attract.
