If Thomson had determined the mass-to-charge ratio of the electron to be –3.35 x 10–12 kg/C, and Millikan had determined the charge of the electron to be –3.20 x 10–19 C, what would the mass of the electron be in grams? Give your answer to 3 significant figures in scientific notation

the number of protons in the nucleus of a given element. has slight luster and conducts electricity at high temperatures like metal.but like a nonmetal,boron is brittle and does not conduct electricity well at low temperatures. in graphite, carbon is a soft,brittle solid.it is reflective,ductile,or malleable.

where are the choice options?

the enthalpy of formation of water is given as -285.8kj/mol, which states that the enthalpy of formation is negative.

negative enthalpy of formation indicates that the heat is released during the reaction process. the heat is released from reaction to the surroundings the enthalpy is expressed with a negative sign with the energy given out in the reaction process.

the formation of water takes place by giving out heat which is -285.8 kj/mol.
