Answer:
Metoprolol tartrate is the immediate-release version of metoprolol while metoprolol succinate is the extended-release version
Explanation:
This means that metoprolol succinate is released over time in the body leading to longer-acting effects. Metoprolol tartrate may need to be taken multiple times per day.
What is the concentration of a solution in
which 60 g of NaCl are dissolved in 1.0 L of water?
Answer:
6%
Explanation:
60 g / 1000 g = 6%
The concentration of a solution in 60 g of NaCl are dissolved in 1L of water will be 6%.
What is concentration?The abundance of an ingredient ratio of the volume of a combination is called concentration. Mass concentration, molar concentration, number concentration, and volume concentration are all examples of mathematical descriptions.
Concentration can be calculated as:
C=m/V.
where, C is concentration , m is mass and V is volume.
It is given that, m = 60 g and V = 1L or 1000 mL.

under what temperature will volume of gas at 0 degree celcius double itself if the pressire is kept constant ????
Answer:
273.15° C
Explanation: Ideal gasses tend to double in volume when their temperature doubles. 0°C = 273.15K so double 273.15 gives 546.3K.
Converting back to Celcius
546.3-273.15 =273.15°C

A student built a model of DNA to show its helical structure in an attempt to display their knowledge of the chemical properties of the 3D structure. In fact, the teacher asked the entire class to create similar models. However, the teacher asks the students to incorporate a biological explanation for how each DNA molecule uniquely codes for different traits. Which component should be incorporated in the student models in order to meet the teacher's expectation for illustrating DNA's ability to code for unique traits? A) The DNA models should have different A:T, C:G ratios. B) The DNA models should have unique nucleotide sequences. C) The DNA models should have different angles of curvature for the helical strands. D) The DNA molecules should have alternating ribose and deoxyribose as the sugars in the backbone.
The DNA sequence determines the different traits, therefore, the student's DNA models should have unique nucleotide sequences.
What determines how each DNA molecule uniquely codes for different traits?The different traits which are produced from the DNA molecule is dependent on the sequence of nucleotides in the DNA molecule.
The unique sequence of nucleotides are known as genes.

What is the percentage by mass of water in the compound FeCl3 • 6H20 ?
Answer:
52.12%
Explanation:
First you need to find the mass of the total molecule. The mass of one atom of Fe is 55.847. The mass of one atom of Cl is 35.453. The mass of O is 16.00, and the mass of H is 1.00. The mass of the whole atom is calculated as follows:
55.847 + 3(35.453) + 6(16.00)+ 12(1.00) = 270.206.
Next calculate the mass of water in the molecule:
(2)1.00 + 16.00 = 18.00(6 molecules) = 108
Finally, divide the mass of water by the mass of the whole molecule and multiply by 100 to get it as a percent:
108/207.206 = 0.52122 x 100 = 52.12%

O c. 94.87 CO2/L
O d. 6.08 CO2/L
The solubility of carbon dioxide at 400 kPa at room temperature is ;
( B ) 0.61 CO2/L
Given data
pressure of CO₂ = 400 Kpa = 3.95 atm
Kh of CO₂ = 3.3 * 10⁻² mol/L.atm
Calculate the solubility of carbon dioxideSolubility = pressure * Kh value of CO₂
= 3.95 atm * 3.3 * 10⁻² mol / L.atm

A compound is 52.0% zinc 9.6% carbon and 38.4% oxygen. Calculate the empirical formula of the compound.
Answer:
So a compound is 52% Zinc(Zn), 9.6% Carbon(C), and 38.4% Oxygen (O). Let’s first start off by assuming that we have 100 g of this compound. This means that we have 52 g of Zinc, 9.6 g of Carbon, and 38.4 g of Oxygen.Zinc = 65.38 g/molCarbon = 12 g/molOxygen = 16 g/molThis means we have:52 g of Zn(1 mol Zn/65.38 g of Zn) ≈0.8 mol of Zn.9.6 g of C(1 mol C/12 g of C) = 0.8 mol of C38.4 g of O(1 mol of O/16 g of O) = 2.4 mol of O.
Explanation:
What we want to do next is divide each element by the common factor of all of them, which is 0.8. In most cases, you divide each element by the element with the least amount of moles. After we divide each by 0.8, you’ll notice you have 1 Zn, 1 C, and 3 O. This gives you the empirical formula of ZnCO3, or Zinc Carbonate.

In response to an aspirin (acetylsalicylic acid) overdose, you would expect to observe which acute compensatory response
Compensatory responses are the compensation mechanism that maintains the body's fluid levels. The increased alveolar ventilation is seen in aspirin overdose.
What is an aspirin overdose?Aspirin or acetylsalicylic acid is a general pain reliever that can cause poisoning when overdosed. It results in tinnitus, hyperventilation, increased heart rate, low blood pressure, fever, dehydration, etc.
Aspirin toxicity decreases the pH making the blood more acidic causing increased ventilation through alveoli to remove the excess carbon dioxide to balance the pH levels.
Therefore, in aspirin poisoning, the increased alveolar ventilation is the acute compensatory response.
