Which general trends in atomic radius and electronegativity are observed as the elements in period 3 are considered in order of increasing atomic number? atomic radius decreases and electronegativity increases. atomic radius increases and electronegativity decreases. both atomic radius and electronegativity increase. both atomic radius and electronegativity decrease?

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
