What is produced by the body to neutralize acidic conditions

Answers

Answer 1

Answer:

Answer:

Buffers.

Explanation:

Hello,

When the body experiences acidic conditions, buffers such as phosphates in form of sodium-based phosphates and bicarbonates are produced by itself in order to stabilize the inner pH. Such buffers are majorly produced in the blood.

Best regards.

Answer 2

Answer:

Final answer:

To neutralize acidic conditions, the body produces buffers, such as bicarbonate ions, which combine with hydrogen ions to regulate blood pH, maintaining it at around 7.4 for proper physiological function.

Explanation:

The human body produces substances known as buffers to neutralize acidic conditions and maintain homeostasis. These buffers include a combination of carbonic acid (H₂CO₃), bicarbonate ions (HCO₃⁻), and carbon dioxide (CO₂). When there's a decrease in blood pH, indicating acidity, bicarbonate ions can bind to free hydrogen ions, forming carbonic acid, which can then be converted to CO₂ and exhaled through the lungs, thereby reducing acidity.

If the blood becomes too alkaline, carbonic acid can release hydrogen ions, lowering pH. Furthermore, the kidneys regulate blood pH by excreting excess hydrogen ions and reabsorbing bicarbonate. An example of this regulation is when lactic acid, produced in our muscles during exercise, is neutralized by bicarbonate ions, forming carbonic acid that breaks down into CO₂ and water.

(3) A dissolves in water, and B does not dissolve in water.
(4) A does not burn in air, and B does burn in air.

Answers

(4) A does not burn in air, and B does burn in air is your answer. Flammability is a chemical property while the rest of these are physical properties.

Final answer:

The correct option is 4.

The ability of a compound to burn in air is a chemical property and can be used to distinguish between two compounds.

Explanation:

The statement that describes a chemical property which can be used to distinguish between compound A and compound B is: (4) A does not burn in air, and B does burn in air. Physical properties like color, melting point, and solubility (options 1, 2, and 3) are characteristics that can be observed without changing the substance into another substance. On the other hand, a chemical property describes how a substance interacts with other substances, including its flammability. Therefore, the ability or inability of a compound to burn in air would be a chemical property.

Fluorine. This element has the greatest electronegativity value, so has the greatest attraction to electrons in a bond.

The fuel used in many disposable lighters is liquid butane, C4H10. Butane has a molecular weight of 58.1 grams in one mole. How many carbon atoms are in 3.50 g of butane?

Answers

First convert grams to molesusing molar mass of butane that is 58.1 g

3.50g C4H10 x (1 molC4H10)/(58.1g C4H10) = 0.06024 mol C4H10

Now convert moles to molecules by using Avogadro’s number

0.06024 mol C4H10 x (6.022x10^23 molecules C4H10)/(1 molC4H10) = 3.627x10^22 molecules C4H10

And there are 4 carbon atoms in 1 molecule of butane, so usethe following ratio:

3.627 x 10^22 molecules C4H10 x (4 atoms C)/(1 moleculeC4H10)
= 1.45 x 10^23 atoms of carbon are present

$\boxed{{\text{1}}{\text{.45}} * {\text{1}}{{\text{0}}^{{\text{23}}}}{\text{ atoms}}}$ of carbon is present in 3.50 g of butane.

Further Explanation:

Mole is a measure of the amount of substance. It is defined as the mass of a substance that has the same number of fundamental units as there are atoms in 12 g of carbon-12. Such fundamental units can be atoms, molecules or formula units.

Avogadro’s number is the number of units that are present in one mole of the substance. Its value is equal to ${\text{6}}{\text{.022}}*{\text{1}}{{\text{0}}^{{\text{23}}}}\;{\text{units}}$ per mole of substance. These units can be electrons, atoms, molecules or ions.

The formula to calculate the moles of butane is as follows:

${\text{Moles of butane}}=\frac{{{\text{Given mass of butane}}}}{{{\text{Molar mass of butane}}}}$ ......(1)

The given mass of butane is 3.50 g.

The molar mass of butane is 58.12 g/mol.

Substitute these values in equation (1).

$\begin{aligned}{\text{Moles of butane}}&=\left({{\text{3}}{\text{.50 g}}} \right)\left( {\frac{{{\text{1 mol}}}}{{{\text{58}}{\text{.12 g}}}}}\right)\n&={\text{0}}{\text{.060220234 mol}}\n&\approx {\text{0}}{\text{.0602 mol}}\n\end{aligned}$

The molecules of butane are calculated as follows:

${\text{Molecules of butane}}=\left({{\text{Moles of butane}}}\right)\left( {{\text{Avogadro's Number}}}\right)$ ......(2)

The moles of butane is 0.060220234 mol.

The value of Avogadro’s number is ${\text{6}}{\text{.022}}*{\text{1}}{{\text{0}}^{{\text{23}}}}\;{\text{molecules}}$ .

Substitute these values in equation (2).

$\begin{aligned}{\text{Molecules of butane}}{\mathbf&{ = }}\left({0.060220234{\text{ mol}}} \right)\left( {\frac{{{\text{6}}{\text{.022}} *{\text{1}}{{\text{0}}^{{\text{23}}}}{\text{ molecules}}}}{{{\text{1 mol}}}}}\right)\n&={\text{3}}{\text{.62646}}*{\text{1}}{{\text{0}}^{{\text{22}}}}{\text{ molecules}}\n&\approx {\text{3}}{\text{.626}}*{\text{1}}{{\text{0}}^{{\text{22}}}}{\text{molecules}}\n\end{aligned}$

One molecule of butane has four carbon atoms. So the number of carbon atoms in ${\text{3}}{\text{.62646}}* {\text{1}}{{\text{0}}^{{\text{22}}}}{\text{ molecules}}$ of butane is calculated as follows:

${\text{Atoms of carbon}}=\left( {{\text{Molecules of butane}}}\right)\left( {\frac{{{\text{4 carbon atoms}}}}{{{\text{1 butane molecule}}}}}\right)$

.......(3)

Substitute ${\text{3}}{\text{.62646}}*{\text{1}}{{\text{0}}^{{\text{22}}}}{\text{ molecules}}$ for the molecules of butane in equation (3).

$\begin{aligned}{\text{Atoms of carbon}}&=\left( {{\text{3}}{\text{.62646}}* {\text{1}}{{\text{0}}^{{\text{22}}}}{\text{ molecules}}}\right)\left({\frac{{{\text{4 carbonatoms}}}}{{{\text{1 molecule}}}}} \right)\n&= 1.45 * {\text{1}}{{\text{0}}^{{\text{23}}}}{\text{ atoms}}\n\end{aligned}$

Therefore the number of atoms of carbon is ${\mathbf{1}}{\mathbf{.45 * 1}}{{\mathbf{0}}^{{\mathbf{23}}}}{\mathbf{ atoms}}$ .

An electron shell is the outside part of an atom around the atomic nucleus.

Elements present in horizontal rows are called periods.

Elements belonging to the same period have same no. of the shell as the electrons are added in the same shell of the element.
