Many common weak bases are derivatives of nh3, where one or more of the hydrogen atoms have been replaced by another substituent. such reactions can be generically symbolized as nx3(aq)+h2o(l)⇌hnx3+(aq)+oh−(aq) where nx3 is the base and hnx3+ is the conjugate acid. the equilibrium-constant expression for this reaction is kb=[hnx3+][oh−][nx3] where kb is the base ionization constant. the extent of ionization, and thus the strength of the base, increases as the value of kb increases. ka and kb are related through the equation ka×kb=kw as the strength of an acid increases, its ka value increase and the strength of the conjugate base decreases (smaller kb value). part a if kb for nx3 is 9.0×10−6, what is the poh of a 0.175 m aqueous solution of nx3? express your answer numerically.

Listen base your answer to the question on the information below.propane is a fuel that is sold in rigid, pressurized cylinders. most of the propane in a cylinder is liquid, with gas in the space above the liquid level. when propane is released from the cylinder, the propane leaves the cylinder as a gas. propane gas is used as a fuel by mixing it with oxygen in the air and igniting the mixture, as represented by the balanced equation below.c3h8(g) + 5o2(g) → 3co2(g) + 4h2o() + 2219.2 kja small amount of methanethiol, which has a distinct odor, is added to the propane to consumers detect a propane leak. in methanethiol, the odor is caused by the thiol functional group (–sh). methanethiol, ch3sh, has a structure that is very similar to the structure of methanol.what is the correct structural formula for a molecule of methanethiol

Read the claim. breakfast is an important meal. it jump starts the body’s process of using calories to break down food. appetite can decrease with age, but going too long without eating causes metabolism to slow down. current research shows that incorporating legumes such as lentils and chickpeas into meals boosts metabolism for twenty-four hours. who might benefit from this claim? people who have a fast metabolism stores that sell exercise equipment people who take vitamin supplements grocery stores that sell legumes
