2CO + O ₂ → 2CO ₂
Explanation:
CO + O ₂ → CO ₂
Left Side
C = 1
O = 3
Right Side
C = 1
O = 2
So we'll balance the oxygen first
2CO + O ₂ → 2CO ₂
Left Side
C = 2
O = 4
Right Side
C = 2
O = 4
Ok so balancing the O has also balanced the C

Calculate Rations. A transformer has ten turns of wire on the input side and 50 turns of wire on the output side. if the input voltage is 120 V, what will the output voltage be?
Answer:
Output voltage = 600 V
Explanation:
Using the transformer equation which simply states that the ratio of the secondary to primary voltages in a transformer equals the ratio of the number of loops in their coils.
Number of input turns/Number of output turns = Voltage of input/voltage of output
10/50 = 120V/voltage of output
Voltage of output = 120 V/0.2
Voltage of output = 600 V

Based on the Lewis/electron dot representation
of the two atoms, predict the ratio of metal
cationic (+) atom to nonmetal anionic (-) atom in the compound
Answer:
A. 1:3
Explanation:
If we look at the ions shown in the image attached to the question, we will notice that we have aluminum (Al^3+), a trivalent ion combining with the iodide ion (I^-).
Aluminum can easily give out its three outermost electrons to three atoms of iodine. If aluminum gives out its three electrons, it achieves the stable octet structure. Iodine atoms have seven electrons in their outermost shell. They only need one more electrons to complete their octet. This one electron can be gotten by the combination of three iodine atoms with one atom of aluminum. One electron each is transferred from the aluminum atom to each iodine atom to form AlI3 with a ratio of 1:3.
Lewis dot structure is a diagrammatic representation of valence electrons in an atom of a molecule.
The ratio of the cations to anions in the given compound is 1:3.
In the given figure, Aluminum has 3 electrons, which can be donated to iodine. Aluminum has atomic number 13, this means that if the element donates three electrons then it will attain a stable electronic configuration.
In the Iodine atom, each iodine needs only one electron to complete its octet. Thus, three atoms of iodine will be required to gain electrons from aluminum.
Thus, the ratio cation to the anion is 1:3.

Answer:
15. 2.66 moles .
16. 2.09L.
Explanation:
Molarity of a solution is simply defined as the mole of solute per unit litre of the solvent. Mathematically, it is represented as:
Molarity = mole /Volume.
With the above formula, let us answer the questions given above
15. Data obtained from the question include the following:
Volume of solution = 1.4L
Molarity = 1.9M
Mole of solute =.?
Molarity = mole /Volume
1.9 = mole / 1.4
Cross multiply
Mole = 1.9 x 1.4
Mole = 2.66 moles
Therefore, the mole of the solute present in the solution is 2.66 moles.
16. Data obtained from the question include the following:
Mole of solute = 0.46 mole
Molarity = 0.22M
Volume of solvent (water) =.?
Molarity = mole /Volume
0.22 = 0.46/Volume
Cross multiply
0.22 x Volume = 0.46
Divide both side 0.22
Volume = 0.46/0.22
Volume = 2.09L
Therefore, 2.09L of water is required.

A saturated solution of sulfur dioxide is prepared by dissolving SO2(g) in 100. g of water at 10.°C and standard pressure.
Determine the mass of SO2 in this solution.
A.) 15g to 18g
B.) 40g to 43g
C.) 53g to 56g
D.) 6g to 8g
Answer:
The correct option is;
A.) 15 g to 18 g
Explanation:
The solubility of sulfur dioxide at room temperature = 94 g/L of water forming sulfurous acid as follows;
SO₂ + H₂O ⇄ HSO₃⁻ + H⁺
Which is a partial reversibly association with water molecules
Whereby 1 liter of water weighs 1 kg
9.4 gram of SO₂ will dissolve in 100 g of water at room temperature of 23 to 24°C
The solubility increases as the temperature reduces therefore as shown from the sulfur dioxide solubility chart we have;
At 10°C the solubility of SO₂ (g) is midway between 150 g to 200 g per kg of water
Therefore;
The solubility of SO₂ (g) is between 15 g to 18 g per 100 of water.
The mass of SO2 in the given solution should be an option a 15g to 18g.
Calculation of the mass:Since the solubility of sulfur dioxide at room temperature = 94 g/L of water forming sulfurous acid likewise:
SO₂ + H₂O ⇄ HSO₃⁻ + H⁺
This represents the partial reversibly association along with water molecules
Here 1 liter of water weighs 1 kg
So we can say that
9.4 gram of SO₂ will dissolve in 100 g of water at room temperature of 23 to 24°C
Due to this, there is an increase in solubility this result in decrease in the temperature
Also, At 10°C the solubility of SO₂ (g) is midway between 150 g to 200 g per kg of water

How do the HOX genes in the paddlefish match the HOX genes in human
Answer:
Hox are transcription factors that are evolutionarily conserved across bilaterians and, therefore, they share sequence homology between paddlefish and humans .
Explanation:
The Hox genes represent a family of homeodomain transcription factors that play roles in the development of the axial and appendicular skeleton, being therefore critical during embryonic development. In this case, the human Hox genes are homologous to homeobox genes found in the paddlefish. These genes have a DNA-binding domain of 60 amino acids which is evolutionarily conserved in bilaterian species including paddlefish and human species.

John Dalton was the chemist that gave the theory of atoms. His atomic model was incorrect as he said that the atoms cannot be further divided, but they are made of smaller particles. Thus, option D is correct.
What is Dalton's atomic model?Dalton's atomic model stated that all matter is composed of atoms that are made of elements with identical properties and mass. He further stated the formation of the compounds from the molecules.
In the theory, he stated that atoms cannot be divided further and are indivisible. This was proven wrong as the atoms are composed of sub-atomic particles namely, electrons, neutrons, and protons.
Therefore, the statement that atoms are indivisible in Dalton's atomic theory is incorrect.
