Considering ideal gas behavior, the volume of 1 mol of gas at STP is 22.4 L; then the volume occupied by 1.9 moles is 1.9mol*22.4L/mol = 42. 6 L.
Answer: 43 L
I would say that you should wear a lab coat, safety goggles, and gloves
when the teacher says so - not everything in a lab is dangerous, so
there is no need to always wear these. But when the teacher says you
should - then you should.
Answer:
0.0100M of AgNO3 contains 0.0100M of Ag+
Explanation:
AgNO3 when ionized yields Ag+ and NO3-. This means that the amount of AgNO3 in solution is equivalent to the amount of Ag+ and NO3- in that same solution.
1M of AgNO3 solution produces 1M of Ag+
1M of AgNO3 solution produces 1M of NO3-
This occurs because of the complete ionization of AgNO3 in solution, allowing complete dissolution of the compound.
Wish I can help, but I don't take chemistry. :(

No, since they are the strongest type of ray only elements that are dense can block them.
