Brass is an alloy, or a combination of two (or more) metals.
Explanation:
The purpose of this seven-page lab report is to use simple and fractional distillation to purify volatile liquids. The boiling points were obtained from the distillate collected drops and the efficiency of the two methods of purification were compared. The introduction experiment, data, conclusion
p = latm
t = 273.15K
R= 0.08206 L atm mol K
75.0g02
16.00 (O₂) = 4.6875mol mol

Ideal gas law: PV = nRT, solve for volume: V = nRT P
V =
4.6875mol 0.08206 L-atm mol. K · 273.15K
V = 105L

Ions are neither polar or non-polar because their are no molecules!!
Answer: i would say D or the last one.
Explanation: According to the law of conservation of mass, the mass of the products in a chemical reaction must equal the mass of the reactants. The law of conservation of mass is useful for a number of calculations and can be used to solve for unknown masses, such the amount of gas consumed or produced during a reaction.
Hope this helps :) Can u plz mark me branliest
