Hello,
In this case, considering the required product which is dinitrogen tetroxide whose molecular formula is N₂O₄, by considering its formation reaction which is starting by both gaseous nitrogen and oxygen as shown below:
Nevertheless, it should be balance since four oxygen atoms are present at the right side, thus, we obtain:
Best regards.
questions with regards to this reaction.

Answer:
2 FeBr₃(aq) + 3 (NH₄)₂CO₃(aq) = Fe₂(CO₃)₃(s) + 6 NH₄Br(aq)
Explanation:
Aqueous solutions of iron(III) bromide and ammonium carbonate react. This is a double displacement reaction that gives place to ammonium bromide and iron (III) carbonate. Iron (III) carbonate is insoluble so it precipitates. The corresponding molecular equation is:
2 FeBr₃(aq) + 3 (NH₄)₂CO₃(aq) = Fe₂(CO₃)₃(s) + 6 NH₄Br(aq)
Answer:
1. Mass of Carbon is 56.89g
2. Mass of Hydrogen is 6.33g
3. Mass of Oxygen is 75.88
Explanation:
The following were obtained from the question.
Mass of the compound = 139.1g
Mass of CO2 produced = 208.6g
Mass of H2O produced = 56.93
1. Determination of mass of Carbon (C). This is illustrated below:
Molar Mass of CO2 = 12 + (2x16) = 44g/mol
Mass of C = 12/44 x 208.6
Mass of C = 56.89g
2. Determination of the mass of Hydrogen (H). This is illustrated below:
Molar Mass of H2O = (2x1) + 16 = 18g/mol
Mass of H = 2/18 x 56.93
Mass of H = 6.33g
3. Determination of the mass of oxygen (O).
This is illustrated below:
Mass of the compound = 139.1g
Mass of C = 56.89g
Mass of H = 6.33g
Mass of O = Mass of compound - (mass of C + Mass of H)
Mass of O = 139.1 - (56.89 + 6.33)
Mass of O = 139.1 - 63.22
Mass of O = 75.88
Answer:
Explanation:
Hello,
In this case, considering that 1 m equals 10 dm, the required diameter of the atom in decimetres is:
Best regards.
The diameter of an atom is approximately 1 * 10^-10 * m, which translates to 1 * 10^-11 decimeters by multiplying the meter measurement by 10.
The subject of this question is a unit conversion. We are trying to convert the diameter of an atom from meters to decimeters.
The process is as follows:
In essence, to convert meters to decimeters, we need to multiply the meter measurement by 10. But because the meter measurement of the atom is in the power of -10, the decimeter equivalent would be in the power of -11.

B) increasing the temperature of the reactant.
C) adding a catalyst to the reaction.
D)adding more reactant
Answer:
C)
Explanation:
C) adding a catalyst to the reaction.
Answer;
-past temperatures
The ratio of oxygen-16 and oxygen-18 isotopes in plankton fossils in deep-sea sediments can be used to determine past temperatures.
Explanation;
-O-16 will evaporate more readily than O-18 since it is lighter, therefore; during a warm period, the relative amount of O-18 will increase in the ocean waters since more of the O-16 is evaporating.
-Hence, looking at the ratio of O16 to O18 in the past can give clues about global temperatures.
liquid 1 and 2 have the same color and mass so the answer would be liquid 1 and 2
