Answer:
Homogenous mixture
Explanation:
Homogenous mixtures like ice cream appear to be uniform, and you cannot see their individual components.
Answer:
Vanderwaals forces
Explanation:
CBr4 is a nonpolar molecule, nonpolar molecules usually possess vanderwaals forces between their molecules as their main attractive force.
CBr4 is nonpolar because the tetrahedral arrangement of the C-Br bonds cancel out the individual dipole moments of each C-Br bond thereby making the compound nonpolar, hence the answer above.
For a 1st order reaction:
In(n/n0)= -k * (time difference)
so k= - In (n/n0)/ (t/t0)
n is concentration at time t and n0 is the concentration at an earlier time t0.
where k is constant.
B
Explanation:
cause carbon is less than all of them in periodic table which therefore least in the group
Hi, not sure if this is what you’re asking, but this would be a chemical change / chemical reaction. Rust is an iron oxide, formed by a redox reaction. :)
