Define each statement in terms of the accuracy and precision its situation shows. True values:

* Boiling Point = 373K

* Freezing Point = 273 K

* Hydrogen mass= 1.00794 amu

1) I measure boiling water to have a temperature of 200 K. I get the same result each time.

2) I measure ice water four times, and get results of 5 K, 234 K, 700 K, and 273 K.

3) I measure a 2 kg weight three times, and get 3.60 kg, 3.45kg, and 3.50 kg for results.

4) I measure the mass of an atom of hydrogen 3 times, and receive the following results: 1.008 amu, 1.007 amu, & 1.009 amu.

i'm assuming that it's c.) red bank..

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.

every chemical equation adheres to the law of conservation of mass, which states that matter cannot be created or destroyed. therefore, there must be the same number of atoms of each element on each side of a chemical equation.
