Plz i have 5 mins only 1. identify one source of carbon that can found in each of these four spheres: atmosphere (air), geosphere (land), biosphere (living organisms) and hydrosphere (water).

What are the genotypic and phenotypic ratios

What is the overall order of reaction for rate = k[no2]2 ? second order 3/2 order third order zero order none of the listed answers are correct

Consider the following reaction at equilibrium. 2co2 (g) 2co (g) + o2 (g) h° = -514 kj le châtelier's principle predicts that the equilibrium partial pressure of co (g) can be maximized by carrying out the reaction a. at high temperature and high pressure b. at high temperature and low pressure c. at low temperature and low pressure d. at low temperature and high pressure e. in the presence of solid carbon
