Answer:
A
Explanation:
Metal atoms are held together by metallic bonds. The metallic bonds are composed of a lattice of positive ions in a 'sea of electrons'.
The metal atoms are held together by strong electrostatic attraction between the positive ions and the 'sea of electrons' leading to high melting point of metals including copper.
Similarly, when a metal undergoes stress, the layers of the metal roll over each other but the lattice remains in place. Hence for metals such as Copper, layers of atoms in the lattice can slide over each other thereby making the metal malleable.
Metals oxidize by electron loss. Since Copper is metal, it can also be oxidized to form copper ions by loosing electrons.
Yes I think yesi,m not really suer
Answer:
0.581 L or 581 mL
Explanation:
As stated in the question, the combined gas law is (P1*V1/T1) = (P2*V2/T2)
Write down the amounts you are given.
V1 = 0.152 L (I was taught to always convert milliliters to liters)
P1 = 717 mmHg
T1 = 315 K
V2 = ?
P2 = 463 mmHg
T2 = 777 K
The variable that is being solved for is final volume. Fill in the combined gas law equation with the corresponding amounts and solve for V2.
(717 mmHg*0.152 L) / (315 K) = (463 mmHg*V2) / (777 K)
0.346 = (463*V2) / (777)
0.346*777 = (463*V2) / (777)*777
268.842 = 463*V2
268.842/463 = (463*V2)/463
V2 = 0.581
Pressure and volume are indirectly proportional. This checks out because the volume increased while pressure decreased. Volume and temperature are directly proportional. This checks out because both volume and temperature increased. This is a good way to check your answers. You can also solve each side of the combined gas law equation to see if they are both the same.
10 meter that spread many of it
It would be 36 because the atomic mass of carbon is 12
