Which of the following is true about the carbon-oxygen cycle?
The atmosphere stores more carbon dioxide than the ocean.
Plants use oxygen to make food during photosynthesis.
Carbon dioxide is added to the atmosphere by burning fossil fuels.
Carbon dioxide is a waste produce of respiration.
Answer:
B. is the answer. :)
Explanation:
have a good day <3
The carbon cycle is the rotation of the carbon and its compound in the atmosphere. carbon is added to the atmosphere by burning fossils and is a waste product of respiration. Thus, options C and D are correct.
What is a carbon cycle?A carbon cycle is a biogeochemical cycle that involves the reuse of the carbon from various sources that involve the atmosphere and organisms. The cycle repeats itself again and again.
When fossil fuel is burnt carbon dioxide along with some gases are released into the atmosphere. Also, carbon dioxide is a waste product of cellular respiration. Most of the carbon is present in rocks, oceans, and the atmosphere.
Therefore, the burning of fossils releases carbon.

Explanation:
This is a chemical reaction for the decomposition of carbonic acid into water and carbon dioxide.
H2CO3→H2O + CO2
How does the reaction support the Law of Conversation Mass?
a). The mass of carbon atoms is reduced during the reaction
b). The mass of the atoms in the reactant equals the mass of the atoms in the products
c). The mass of hydrogen atoms is the only thing that remains the same before and after the reaction
Answer:
H2CO3 → CO2 + H2O decomposition in the presence of H2O, HCOOH, CH3COOH, H2SO4 and HO2 radical: instability of the gas-phase H2CO3 molecule in the troposphere and lower stratosphere†
Explanation:have fun
The correct statement given the data is:
The mass of the atoms in the reactant equals the mass of the atoms in the products (Option B)
What is a chemical equation ?Chemical equations are representations of chemical reactions using symbols and formula of the reactants and products.
The reactants are located on the left side while the products are located on the right side.
Reactants —> Products
The balancing of chemical equations follows the law of conservation of matter which states that matter can neither be created nor destroyed during a chemical reaction but can be transferred from one form to another.
Considering the equation given from the question
H₂CO₃ —> H₂O + CO₂
Reactant
H = 2 atomsC = 1 atomO = 3 atomsProduct
H = 2 atomsC = 1 atomO = 3 atomsFrom the description of the reactant and product, w can see that the atoms in both reactant and product are the same. Hence the equation support the law of conservation of mass

An element has a mass of 39.2 and an atomic number of 19. How many protons does this element have? How many neutrons? How many electrons?
Answer:
19 protons, 19 electrons, and 3 neutrons
Explanation:
the atomic number is 19 so the protons are the same, 19, and the electrons are the same as the proton, because protons are positive and electrons are negative so they have to balance out and the neutrons ➗ mass number by the atomic number.

2. The atomic mass of Mercury is 200.592. The atomic number for Mercury is 80. As protons and neutrons are only available as a whole, how do scientists determine an atomic mass reported as a decimal number? Explain your answer using Mercury as an example.
Answer:
1) 157 Neutrons, 2) the decimal is simply is due to isotopes, because the elements atomic mass is an average of these isotopes multiplied by its abundance(or percentage on earth.) For Mercury, it has many isotopes(an element with a different mass number, logically the atomic mass listed on the periodic table as a mass has 100% abundance, therefore this is used to find the most abundant mass for that particular element/molar mass) likewise, Mercury has an atomic mass of 200.59 u, as one mol of Hg(mercury) is 200.59 grams.
Explanation:
The formula for Neutrons in an atom of an element is calculated by finding the

Which scientist's atomic model is most recent?
A. Dalton's
B. Rutherford's
O c. Thomson's
D. Bohr's
Answer:
D. Bohr's
Explanation:
I just did the test, and got it right! Hope this helps.
It was Niels Bohr who discovered the modern atomic model. This model revealed the revolution of electrons and determination of energy levels and momentum of electrons. Hence, option D is correct.
What was atomic model?Various atomic models discussed about the structure and electronic properties of atom. It was Dalton who found that atom is indivisible and combination of atoms make a compound.
Later J.J . Thomson discovered electrons the subatomic particles. But this model does not found the orbitals for electrons and energy levels. Rutherford proposed then the nuclear model of atom.
Nuclear model of atom described that the nucleus contains the positively charged particles protons and the negatively charged particles electrons are revolving around the nucleus.
Later Bohr explained the revolution of electrons around the nucleus with the aid of quantum mechanics and he found that the electrons revolves through a circular paths of fixed energy. By this model momentum and energy of electrons can be calculated.
Hence, Bohr's model is most recent.
