Density = mass divided by volume. 15/30 is 1/2 so the density is 1/2 or 0.5 g/cm
Answer: When atoms combine through chemical bonding, they form compounds—unique structures composed of two or more atoms. The basic composition of a compound can be indicated using a chemical formula.
Hope I was able to help! Mark me brainly it would help a lot!:)
Yea it can kill you in many ways.
275 mm = 27.5 cm
45mg = 4.5g
25cm = 250 mm
Not sure about number 8
he mass defect of the helium nucleus ⁴He₂ is 0.030377 u
Further explanation
Mass defect means the difference between the mass of particles forming an atom with an atomic mass.
Δm = mass defect ( u )
mp = mass of proton ( u )
me = mass of electron ( u )
mn = mass of neutron ( u )
M = atomic mass ( u )
A = mass number
Z = atomic number
Let us now tackle the problem !
