Suppose you light a Bunsen burner and notice that the flame is very yellow and too short. To get a blue flame, you should ________further. To increase the size of the flame, you should _____________the _____________further.
Answer:
In the given case, to get a blue flame, one should open the air inlet further. To increase the size of the flame one should open the gas regulator further. When one opens the air inlet, more amount of oxygen goes within, and thus, one can get a more intense form of blue flame.
When one opens the gas regulator more concentration of gas goes and the larger the size of flame one gets.
To regulate a bunsen burner follow this procedure
To get a blue flame, you should rotate the wheel of the burner anticlockwise further to reduce the level of oxygen flow.
To increase the size of the flame, you should rotate the wheel clockwise further
The bunsen burner is an apparatus in the laboratory used to carry out experiment when heating of substance is required, hence it is used to add heat to substances, it has a wheel used to regulate the flow of air which is required for combustion, it has a hose which is used to tap gas to the burner

3. Find
out the initial energy level (n) of an electron that results in the emi ssion of light of
wavelength 486 nm in the Balmer series?
Answer:
4
Explanation:
The Balmer series refers to a series of spectral emission lines of the hydrogen atom arising from electronic transitions from any higher level and terminating at the the energy level n= 2.
Using the relation;
1/λ = 1.09737*10^7 (1/2^2 -1/n^2initial)
We now have;
1/486 *10^-9 = 1.09737*10^7 (1/2^2 -1/n^2initial)
0.1875 = 1/2^2 -1/n^2initial
1/n^2initial = 1/2^2 - 0.1875
1/n^2initial = 0.0625
n^2initial = 16
ninitial = 4

A child is prescribed morphine sulfate at 35.0 mcg/kg/dose. The child weighs 85 lb and the solution is available as a 5.0-mg/mL vial. How many milliliters should be injected?
Answer:
270 mL
Explanation:
First we convert the child's weight to kg:
85 lb * [tex]\frac{453.592g}{1 lb} *\frac{1kg}{1000g}[/tex] = 38.56 kgSo the total mass of morphine sulfate that should be injected is:
38.56 kg * 35.0 mg/kg/dose = 1349.6 mg/doseFinally we calculate the volume that should be injected, using the concentration of the available solution:
1349.6 mg ÷ 5.0 mg/mL = 269.9 ≅ 270 mLThe accurate millilitre is 268 mL.
First of all, we must obtain the mass of the child in kilograms;
1 Ib = 0.45 Kg
85 lb = 85 lb × 0.45 Kg/1 Ib
= 38.25 Kg
If 1 Kg takes 35.0 mcg/kg/dose
38.25 Kg takes 38.25 Kg × 35.0 mcg/kg/dose/1 Kg
= 1338.75 mg/dose
Hence;
1338.75 mg/dose/5.0-mg/mL = 268 mL

Calculate the theoretical yield of aspirin obtained when 2.0 g of salicylic acid and 5.0 mL of acetic anhydride (density = 1.08 g/mL) 2. if 1.9 g f asprin were obtained in this experiment, what would be the percent yield?
Answer:
The percent yield would be 73%
Explanation:
The balanced reaction for the obtention of acetylsalicylic acid (aspirin) is the following:
Salicylic acid + acetic anhydride → acetylsalicylic acid + acetic acid
C₇H₆O₃ + C₄H₆O₃ → C₉H₈O₄ + C₂H₄O₂
According to the reaction, 1 mol of salicylic acid reacts with 1 mol of acetic anhydride to give 1 mol of acetylsalicylic acid (aspirin) and 1 mol of acetic acid.
1 mol aspirin (C₉H₈O₄) = (9 x 12 g/mol) + (8 x 1 g/mol) + (4 x 16 g/mol)
= 180 g
1 mol salicylic acid (C₇H₆O₃) = (7 x 12 g/mol) + (6 x 1 g/mol) + (3 x 16 g/mol)
= 138 g
1 mol acetic anhydride (C₄H₆O₃) = (4 x 12 g/mol) + (6 x 1 g/mol) + (3 x 16 g/mol)
= 102 g
The stoichiometric ratio is = 138 g salicylic acid/102 g acetic anhydride= 1.35
We have:
2.0 g salicylic acid
acetic anhydride = 5.0 mL x 1.08 g/mL = 5.4 g
The reactants ratio is = 2.0 g salicylic acid/5.4 g acetic anhydride = 0.37
0.37 < 1.35 , therefore salicylic acid is the limiting reactant.
Now, we use the amount of salicylic acid to calculate the theoretical amount of aspirin. For this, we know that 1 mol of aspirin (180 g) is obtained from 1 mol of salycilic acid (138 g):
theoretical yield= 180 g aspirin/138 g salycilic acid x 2.0 g salycilic acid = 2.61 g aspirin
actual yield = 1.9 g
Finally, we calculate the yield:
percent yield = actual yield/theoretical yield x 100
= 1.9 g/2.6 g x 100 = 72.8% ≅ 73%

A The atoms is a positive sphere with negative electrons embedded in it.
B Electrons orbit the nucleus in set, circular orbits.
C The atoms has a tiny, massive nucleus at its center with electrons surrounding it
D The atoms is a solid, indivisible sphere
Answer:
C The atoms has a tiny, massive nucleus at its center with electrons surrounding it
Explanation:
From the experiment by Rutherford, he suggested a model of the atom where there is a tiny but massive nucleus at the center with electrons surrounding it.
Rutherford found that most of the alpha particles in his gold foil experiment pass through but a few were deflected back. He suggested an atomic model to explain his observation. In this model, the atom has small positively charged center where the mass of the atom is concentrated. Surrounding the nucleus is a large space containing the electrons.Balance the following redox reaction if it occurs in basic solution.

A heliox deep-sea diving mixture contains 2.0 gg of oxygen to every 98.0 gg of helium. What is the partial pressure of oxygen when this mixture is delivered at a total pressure of 8.0 atm?
Answer:
The correct answer is 0.020 atm.
Explanation:
Partial pressure is calculated by using the formula,
Partial pressure = Mole fraction × Total pressure
The partial pressure of oxygen in a mixture can be calculated by using the formula,
Mole fraction of oxygen in mixture = Number of moles of oxygen / No. of moles of oxygen + No. of moles of Helium
(1 gg or gigagram is equal to 10⁹ grams)
= 2 × 10⁹/32 /2 × 10⁹/32 + 98 × 10⁹ / 4
= 2.54 × 10⁻³
Now the partial pressure of oxygen = Mole fraction of oxygen × Total pressure of oxygen

what would happen to an atom in its ground state of external energy was applied to the electrons g
Answer:
See explanation
Explanation:
According to Bohr's theory, when external energy is supplied to an atom, its electrons absorb energy and move from a lower energy level to a higher energy level.They quickly return to their original level and re-radiate the absorbed energy as a photo of light.
Hence, when an atom in ground state receives external energy, it becomes excited because energy is transferred to its electrons and they move from lower to higher energy level.
The electron after getting the energy would jump to an orbital further away from the nucleus.
• Ground state refers to the lowest energy state an atom can be at. When an electron in an atom captivates energy it is considered to be in an excited state.
• An excited atom becomes unstable and seem to align itself to move back to its lowest energy state.
• When an atom in its ground state is supplied with an external energy, the energy is absorbed by the atom and the electron becomes excited and jumps to an orbit , that is, distant from the nucleus.
• It can be said that electron attains higher energy state, with the absorption of more energy by the atom, the electron further moves to higher state till it becomes a free electron and no longer remains the part of the atom.
Thus, the electron after getting the energy would jump to an orbital further away from the nucleus.

A concentration cell is one in which both the anode and cathode are the same but with different concentrations. Calculate the cell potential with [Zn2+] = 0.10 M for the cathode and the [Zn2+] = 0.010 M for the anode?
Answer:
The cell potential = +0.03 V
Explanation:
The half reactions for the cells are given below:
Oxidation half reaction (anode): Zn(s) ----> Zn²⁺(aq) + 2e⁻
Reduction half reaction (cathode): Zn²⁺(aq) + 2e⁻ -----> Zn(s)
To calculate cell potential of the cell, we use the equation given by Nernst, which is given as: Ecell = E°cell - (0.0591/n) log Q
where Q = Concentration of dilute solution/Concentration of concentrated solution = 0.01/0.1
n = number of moles of electrons transferred = 2
Since, the cell is a concentration cell, E°cell = 0
therefore, the Nernst equation becomes, Ecell = - (0.0591/n) log Q
substituting the values;
Ecell = - (0.0591/2) log (0.01/0.10)
Ecell = +0.03 V
Therefore, the cell potential = +0.03 V
