Answer:
It is not an oxidation-reduction reaction. The formation of carbon dioxide and water are redox reactions which involve the oxidation of carbon and hydrogen respectively with oxygen being reduced in both the case.

Answer:
0.0018 moles
Explanation:
Given data:
mass of aspirin= 0.325 g
molar mass of aspirin= 180.1589 g/mol
number of moles=?
Formula:
number of moles= mass in gram/ molar mass (g/mol)
Solution:
now we will put the values in given formula:
number of moles of aspirin= mass of aspirin/ molar mass of aspirin
number of moles= 0.325 g/ 180.1589 g/mol
number of moles = 0.0018 mol
Mole:
Mole is the unit of amount in chemistry. it is SI unit and represented by "mol".
Example;
one mole of hydrogen has a mass of 1.008 g and contain 6.022× 10∧23 atoms.

Answer:
Adhesive forces and cohesive forces
Explanation:
Cohesive forces is how much the water molecules stick to each other and adhesive forces are to which extinct they stick to other surfaces.
When we pull the paperclip upward the water molecules adhere to it due to adhesive forces. While the water on the clip is remain connected to water in the glass because of cohesive forces.
So if the adhesive forces dominates the water will be pulled out and if the cohesive forces dominate it will remain with other water in the cup.
The answer will be B) MgCl2 because magnesium has 2 valence electrons and is a metal and chlorine has the atomic number of 17 and is a metal and in order to form an ionic compound, you must have 1 metal and 1 nonmetal
