The second option
Explanation:
Check
2×2Fe = 4Fe. Both sides have 4 Fe's
2x3 O = 3x2 O Both sides have 6 O's
3x1C = 3 C Both sides have 3 C's

Answer: D
Explanation:
Weight by definition is mass multiplied by the acceleration of gravity. So, weight is the force of gravity
Explanation:
oxygen and are negatively charged anions because the oxygen atoms attract electrons. Ammonium is one of the few positively charged polyatomic ions or cations and doesn't contain oxygen.
Answer:
Volume = 5.73L
Explanation:
Data;
V1 = 3.75L
P1 = 0.980atm
P2 = 0.641atm
V2 = ?
This question involves the use of Boyle's law, which states that, the volume of a fixed mass of gas is inversely proportional to its pressure provided that temperature remains constant.
Mathematically,
V = kP, k = PV
P1V1 = P2V2 =P3V3=........=PnVn
P1V1 = P2V2
V2 = (P1 * V1) / P2
V2 = (0.980 × 3.75) / 0.641
V2 = 5.73L
The final volume of the gas is 5.73L
