Given data:
Diameter of the gold wire (d) = 0.175 cm
Length of the gold wire (l) = 1.00 *
cm
Volume of the given gold wire = volume occupied by a cylindrical object\
= π *
*l
here r = radius of the cross section
where : r = d/2
Hence the volume V = π *
*l
= 
Density of gold = 19.3 g/cm3
Weight of the gold wire = Density * volume
=
*
= 
The density of the carbon tetrachloride is 1.59 g/mL.
Mass of CCl₄ = 703.55 g – 345.8 g = 357.75 g
Density = mass/volume = 357.75 g/225 mL = 1.59 g/mL
Answer:
1.Physical. People measure water by themselves.
2.Physical. People chop wood.
Explanation:
(this is all I can answer for you. you have to explain it by yourself tho.)
I dont know if I'm correct so you should double check.
C because it’s reshaping it, it stays the same but just reshaping it
Answer:
mass number
Explanation:
The sum of the protons and neutrons in an atom equals the mass number of such an atom.
- Mass number is the mass of an atom.
- The mass of an atom is concentrated in the nucleus
- The particles in the nucleus are the protons and neutrons.
So;
Mass number = number of protons + number of neutrons.
