Answer:
A.
Explanation:
The paper clip allows elictricity to pass, unlike the eraser or paper
(1) Copper:
Copper has the atomic number : 29
Cu2+ means that it lost 2 electrons, therefore, the total number of electrons is 29-2 = 27 electrons.
The electronic configuration is:
1s2 2s2 2p6 3s2 3p6 3d9
(2) Silver:
Silver has atomic number : 47
Ag + means that it lost one electron, therefore, the total number of electrons is 47-1 = 46 electrons
The electronic configuration is:

Answer:
3.60 mol CO₂
Explanation:
Balanced chemical reaction:
2CO + O₂ ⇒ 2CO₂
The molar ratio between CO₂ and CO is 1:1
2CO₂/2CO = CO₂/CO
Thus, the moles of CO₂ produced from 3.60 moles of CO is 3.60 moles:
(3.60 mol CO)(CO₂/CO) = 3.60 mol CO₂
True - more particles will be able to hit off the tire wall, therefore higher pressure
