Answer: 75.3%
Explanation:
Mg molar mass = 24
MgCl2 molar mass = 94
—> 94 x 10 / 24
29.5/1 x 24/94 x 10
= 29.5 x 24 / 94 x 10
since we are looking for percentage yield we multiply by 100
= 29.5 x 24 x 100 / 94 x 10 = 75.3%
What is the purpose of adding 0. 1% agar to the trypticase nitrate broth when conducting the nitrate reduction test?.
Agar is used to assist establish an anaerobic environment that promotes nitrate reduction.
Nitrate Reduction test:
The nitrate in the broth is converted to nitrite by organisms that can produce the nitrate reductase enzyme, which can then be further converted to nitric oxide, nitrous oxide, or nitrogen. Anaerobic respiration and denitrification are two processes that can convert nitrate to a variety of compounds. While denitrification only reduces nitrate to molecular nitrogen, anaerobic respiration employs nitrate as the bacterium's final electron acceptor, reducing it to a range of chemicals.The nitrate reduction test is based on the detection of nitrite and its capacity to produce a red precipitate (prontosil), which is a water-soluble azo dye, when it combines with sulfanilic acid to create a complex (nitrite-sulfanilic acid).Learn more about the Nitrate reduction test with the help of the given link:

The IR spectrum of a solid can be taken by dissolving it to create a solution. An appropriate solvent is?
The IR spectrum of a solid can be taken by dissolving it to create a solution. An appropriate solvent is carbon tetrachloride as its IR stretches are( only in tne fingerprint region) not visible in the region of infrared.
Non-polar solvents do not show peaks at the region of IR frequency because they do not have dipoles which absorb the infrared light. However, it has been noted that some of these solvent interfere the reaction spectra or absorb within the range of spectra. This property makes them suitable solvents in IR Spectroscopy.
Therefore non-polar solvents such as CCl4 or Carbon disulfide are appropriate for the IR spectrum. They also do not interfere with the halide disks used in the spectrometer, as a solvent like water would.

The results of photosynthesis are used by cellular respiration, and photosynthesis first uses the results of cellular respiration.
Enthalpy of photosynthesis and cellular respiration:In the mitochondria, cellular respiration combines oxygen and glucose to produce ATP, along with water and carbon dioxide. Sunlight energy is used during photosynthesis to create glucose and separate oxygen from carbon dioxide and water. Globally, the exchange of carbon dioxide and oxygen during photosynthesis or cellular respiration serves to maintain stable levels of oxygen and carbon dioxide in the atmosphere.
Cellular Respiration: [tex]C_6H_1_2O_6+ 6O_2[/tex] → [tex]6CO_2 + 6H_2O[/tex]
Because CO₂ and H₂O are less energetic than the reactants, most notably glucose, the reaction is exothermic and has a negative enthalpy (ΔH < 0). This also makes sense because breathing causes glucose to be converted to energy.

18mL of a 16M H₂SO₄ solution is required to prepare.
Dilution is the process of lowering a solute's concentration in a solution. It usually just involves mixing the solution with more solvent, and much more water. A solution is diluted when more solvent is added without increasing solute. The final mixture is thoroughly mixed to make sure that every component is the same.
The formula for the dilution of a solution is
M₁V₁ = M₂V₂
where,
M is molarity and V is the volume of the solution in liters.

C3Hg has a higher lower boiling point than C₂H6-
Answer:
C₃H₈ has a higher boiling point than C₂H₆
Explanation:
The boiling point is the temperature at which the intermolecular forces between molecules are overcome and the state of the substance changes from liquid to gas.
Since these are both hydrocarbons (molecules containing just carbon and hydrogen), the strength of their intermolecular bonds should be the same. However, since C₃H₈ is larger, it can form more of these intermolecular bonds. Thus, it takes more energy and a higher temperature to overcome the increased amount of forces.
What instrument is used for measuring the heat energy absorbed or released in a chemical reaction?
How can we increase the rate of collisions between the reactants in this reaction? mg 2hcl → mgcl2 h2
The frequency of collisions between the two reactants increases as the concentration of the reactants increases. When collisions happen, they don't always cause a reaction (atoms misaligned or insufficient energy, etc.). Higher concentrations result in more collisions and reaction opportunities.
Increasing a reactant's surface area increases the frequency of collisions and thus the reaction rate. The surface area of several smaller particles is greater than that of a single large particle. The greater the available surface area for particles to collide, the faster the reaction will occur.
How does concentration affect the rate of collisions between reactants?Thus, we can conclude that by increasing the concentration of Mg in the reaction mixture we increase the rate of collisions between the reactants in this reaction.

Q4. When 20 g of salt is added to a beaker containing 100 g of water, the salt dissolves and seems to disappear as a solution is formed. A) What is the mass now? B) Explain your answer.
The mass of the solution is equal to 120 g. As the salt dissolves in water so it disappears when the solution is formed.
Why does salt dissolve in water?The salt dissolves in water at the molecular level, due to electrical charges. Due to this fact that both water and salt are polar, with positive and negative charges on opposite sides of their molecule. The bonds in salt are ionic and have an electrical charge.
Likewise, a water molecule is also ionic in nature, but the covalent bonds are present with two hydrogen atoms and one oxygen atom, which has a negative charge. The salt dissolves because the covalent bonds of water molecules are stronger than the ionic bonds present in the salt molecules.
The mass of the given salt is equal to 20 g while the mass of water is 100g. The total mass of the solution is equal to the sum of the mass of the solute and the mass of the solvent. Therefore, the mass of the solution will be equal to 120 grams whether the salt gets dissolved in water and get disappeared.

The pH of the solution at 25 degree celsius of 1.3 × 10⁻⁶ moles of a sample of Sr(OH)₂ is 10.02.
How do we calculate pH?The pH of any solution gives an idea about the acidic and basic nature of the solution and the equation of pH will be represented as:
pH + pOH = 14
Given that,
Moles of Sr(OH)₂ = 1.3 × 10⁻⁶ mol
Volume of solution = 25mL = 0.025L
The concentration of Sr(OH)₂ in terms of molarity = 1.3×10⁻⁶/0.025
= 5.2×10¯⁵M
Dissociation of Sr(OH)₂ takes place as:
Sr(OH)₂ → Sr²⁺ + 2OH⁻
From the stoichiometry of the reaction 1 mole of Sr(OH)₂ produces 2 moles of OH⁻.
Given that the base is a strong base and that it entirely dissociates into its ions, the hydroxide ion concentration is 5.2×10¯⁵×2 = 1.04×10¯⁴ M.
pOH = -log[OH⁻]
pOH = -log(1.04×10¯⁴)
pOH = 3.98

The thermite contains a mass ratio of ferric oxide and aluminium of 3:1.
It is used to weld broken iron pieces thermally. The reduction of aluminium ferric oxide is extremely exothermic, so the iron produced would be in the molten state.
Fe2O3+2Al→Al2O3+2Fe+heat
Thus, redox reaction of aluminum and ferrous oxide produce thermite.
