How could you test your hypothesis? Find the total mass of the water and the dry pasta, then cook the pasta and measure the mass of the cooked pasta and the water in which it is being cooked. Find the mass of the dry pasta, then cook the pasta, drain it, and find the mass of the cooked pasta.

since the atomic number is the number of protons in the nucleus, as we move to the left on the periodic table, the electrostatic pull between the nucleus and the valence electron shell decreases. as we move down a group (vertical column), the valence shell energy level gets further and further from the nucleus.

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.

explanation:

0.07 g/cm³

1.37 g/cm³

i believe the answer is 5,000
