molecules in both the metal and the surrounding air will start moving at lower speeds.
molecules in both the metal and the surrounding air will start moving at higher speeds.
the air molecules that are surrounding the metal will slow down, and the molecules in the metal will speed up.
the air molecules that are surrounding the metal will speed up, and the molecules in the metal will slow dow

What type of organic molecule comprises the majority of a potato?

Citric acid has a ph between 1 and 3.  it is considered to be aa. weak acidb. weak basec. strong based. strong acid

Percent ionization for a weak acid (ha) is determined by the following formula: percent ionization=[ha] ionized[ha] initial×100%for strong acids, ionization is nearly complete (100%) at most concentrations. however, for weak acids, the percent ionization changes significantly with concentration. the more diluted the acid is, the greater percent ionization. a certain weak acid, ha, has a ka value of 9.4×10? 7.part acalculate the percent ionization of ha in a 0.10 m solution. part bcalculate the percent ionization of ha in a 0.010 m solution
