= 320mg of magnesium hydroxide

= 32mg of simethicone

recommended doses = 4 times * 2 tea spoon = 8 tea spoon/ day

given = 1 tea spoon = 5 ml

8 tea spoon = 40 ml

hence,

amount of aluminum hydroxide = 320/4 * 40 = 3200mg = 3.2 g

amount of magnesium hydroxide = 320/4 * 40 = 3.2 g

amount of  simethicone = 32/4 * 40 = 320 mg = 0.32g

Atoms with an even number of protons and an even number of neutrons tend to be the most stable. Thus, the correct option for this question is D.

Protons may be defined as the type of subatomic particles which are considerably present within the nucleus of an atom along with neutrons. These subatomic particles are positively charged in nature. It was thought that Ernest Rutherford discovered these particles.

The oddness of the number of protons and neutrons leads to lowering the nuclear binding energy of an atom. The number of protons indicates the atomic number of an atom, while the number of neutrons impacts the charge of an atom.

Therefore, atoms with an even number of protons and an even number of neutrons tend to be the most stable. Thus, the correct option for this question is D.

When HCl is added to aqueous solution of sodium sulphate aqueous solution, sulfuric acid is formed, and the solution's chemical makeup and acidity get changed.

Thus, several chemical reactions happen when HCl is introduced to a sodium sulphate aqueous solution. While sodium sulphate breaks down into 2 Na+ ions and SO4^2- ions, HCl splits into H+ and Cl- ions. When the H+ ions from HCl interact with the SO4^2- ions, sulfuric acid, a more potent acid, is created.

The solution's H+ ion concentration rises as a result of this reaction, altering the equilibrium in favor of the products. As a result, the system's equilibrium is upset, which causes sulfuric acid to form. The solution's chemical makeup and acidity ultimately alter as a result of the addition of HCl.

FALSE, the isotope carbon-14 decays to nitrogen-14 over a half-life of 5,730 years. these isotopes could be used to determine the age of rocks formed early in the cenozoic era, approximately 60 million years ago.

Having the chemical symbol C and atomic number 6, carbon is an element with the meaning "coal" in Latin. It is nonmetallic and tetravalent, meaning that four of its atom's electrons may be used to create covalent chemical connections. The periodic table's group 14 is where it belongs. Only 0.025 percent of the crust of the Earth is made up of carbon. The bond sequence affects a bond's strength. Because shorter bonds have a higher bond strength than longer bonds, the higher the bond order, the stronger the bonds are. The bond order of carbon dioxide is 2, that of carbon monoxide is 3, and that of the carbonate ion is 1.33.

Explanation:

The graph indicates that the reaction reaches equilibrium around 1.5 seconds. The graph shows how the concentrations of reactants and products change over time until they eventually become constant. So, the correct option is D.

Equilibrium is a state in a chemical process when forward and backward reactions occur at the same rate, meaning that the concentrations of reactants and products do not change with time. In other words, the forward reaction rate equals the reverse reaction rate.

In the example above, the graph indicates that the reaction reaches equilibrium in about 1.5 seconds. The graph shows how the concentrations of reactants and products change over time until they eventually become constant. This indicates that the reaction has reached equilibrium when obtained in approximately 1.5 seconds.

The change in temperature from start to finish for the air and each of the samples would be calculated by subtracting the initial temperature from the final temperature. For example, if the initial temperature of the air was 20°C and the final temperature was 15°C, the change in temperature would be -5°C.

The water sample that lost the least amount of heat energy over the 6-minute time interval would be the one with the smallest change in temperature. In the example above, if the change in temperature for water sample 1 was -3°C and the change in temperature for water sample 2 was -4°C, water sample 1 would have lost the least amount of heat energy.

The rate of heat loss was not constant during each experiment because the slope of the lines on the graph is not constant. The slope of the line represents the rate of heat loss, and if the slope is not constant, the rate of heat loss is not constant.

The material that was the best insulator would be the one with the smallest change in temperature. In the example above, water sample 1 would be the best insulator because it had the smallest change in temperature.

Answer:

True

Explanation:

Energy is the ability or capacity to do work

According to the given statement Total amount of heat absorbed = 5,922 J+15,792 J is 21,714 J.

The amount of energy absorbed or released during a chemical reaction can be expressed in terms of Calorie and joule.

The SI unit of energy is the joule (J) and is used to express energy as both heat and work.

Mass of sample m = 47.00 g

specific heat capacity of water c = 4.2Jg −1 K −1

specific latent heat of fusion of ice L = 336Jg −1

Amount of heat energy absorbed when 47.00 g of sample at 0° C changes into 30°C =

47 x 4.2 × 30 = 5,922 J.

Amount of heat energy absorbed when 47.00g of sample at 0° C changes into ice at  0° C = 47 × 336J = 15,792 J.

Total amount of heat absorbed = 5,922 J+15,792 J.

Answer:

Explanation:

The movement causes the density to rise and therefore transfer more heat

For the reaction of combustion of 74.3 g of butane with 132 kg of oxygen, we have:

a. The limiting reactant is butane

b. The mass of carbon dioxide obtained by heating butane is 225.33 grams.

c. 131734.8 grams or 131.73 kilograms of oxygen remains unreacted.

a. The balanced reaction is the following:

2C₄H₁₀ + 13O₂ → 8CO₂ + 10H₂O     (1)  

To find the limiting reactant, we need to calculate the initial number of moles of butane and oxygen

\( n_{C_{4}H_{10}}_{i} = \frac{m_{C_{4}H_{10}}}{M_{C_{4}H_{10}}} = \frac{74.3 g}{58.12 g/mol} = 1.28 \:moles \)

\( n_{O_{2}}_{i} = \frac{m_{O_{2}}}{M_{O_{2}}} = \frac{132000 g}{31.99 g/mol} = 4126.3 \:moles \)

From equation (1) we have that 2 moles of C₄H₁₀ react with 13 moles of O₂, so the number of oxygen moles needed to react with 1.28 moles of C₄H₁₀ is:

\( n_{O_{2}}_{r} = \frac{13\:moles\:O_{2}}{2\:moles\:C_{4}H_{10}}*1.28\:moles\:C_{4}H_{10} = 8.32\:moles \)

We need 8.32 moles of O₂ to react with butane and initially we have 4126.3 moles, so the limiting reactant is butane.

b. The mass of CO₂ can be found with the limiting reactant

From equation (1), 2 moles of C₄H₁₀ react with oxygen to produce 8 moles of  CO₂, so the number of moles of CO₂ produced is:

\( n_{CO_{2}} = \frac{8\:moles\:CO_{2}}{2\:moles\:C_{4}H_{10}}*1.28\:moles\:C_{4}H_{10} = 5.12\:moles \)

Then, the mass of CO₂ is:

\( m_{CO_{2}} = n_{CO_{2}}*M_{CO_{2}} = 5.12 \:moles*44.01 g/mol = 225.33 g \)

Hence, the mass of CO₂ obtained is 225.33 grams.

c. The number of moles of the excess reagent can be calculated as follows

\( n_{O_{2}} = n_{O_{2}}_{i} - n_{O_{2}}_{r} = (4126.3 - 8.32) \:moles = 4118 \:moles \)  

Now, the mass of oxygen that remains after the reaction is:

\( m_{O_{2}} = 4118\:moles*31.99g/mol = 131734.8 g = 131.73 kg \)

Therefore, 131734.8 g or 131.73 kg of oxygen remains unreacted.
