Answer:

When CO2 levels become excessive, a condition known as acidosis occurs. This is defined as the pH of the

blood becoming less than 7.35. The body maintains the balance mainly by using bicarbonate ions in the

blood. As the body responds to neutralize this condition, an electrolyte imbalance – an increase of plasma

chloride, potassium, calcium and sodium, can occur.

Hydrodistillation explain ????

777dan777 [17]

Answer:

Explanation:

Hydrodistillation is a traditional method for the extraction of bioactive compounds from plants. In this method, plant materials are packed in a still compartment then water is added in sufficient amount and brought to a boil. ... The vapor mixture of water and oil is condensed by indirect cooling with water.

Why must living things rely on thousands of catalysts for chemical reactions necessary for life?

Murrr4er [49]

Well, you don't need enzymes (biological catalysts) if you're willing to wait a century or two to digest a burger.

Without catalysts, complex reactions like digestion would take too long and the organism could not extract energy from the nutrients it eats in a practical time frame.

In addition, speed is everything in the biological world.

Some reactions and their speed relative to other organisms reactions determines who survives and who doesn't, among other aspects of life.

If a plant is slow to photosynthesize and grow in a habitat high in competition for sunlight real estate, other autotrophs will surely take over.

Determine the expected diffraction angle for the first-order diffraction from the (111) set of planes for FCC nickel (Ni) when m

faust18 [17]

Answer:

56°

Explanation:

First calculate $a:$

$a=2 R \sqrt{2}=2(0.1246) \sqrt{2}=0.352 \mathrm{nm}$

The interplanar spacing can be calculated from:

$d_{111}=\frac{a}{\sqrt{1^{2}+1^{2}+1^{2}}}=\frac{0.352}{\sqrt{3}}=0.203 \mathrm{nm}$

The diffraction angle is determined from:

$\sin \theta=\frac{n \lambda}{2 d_{111}}=\frac{1(0.1927)}{2(0.2035)}=0.476$

Solve for $\theta$

$\theta=\sin ^{-1}(0.476)=28^{\circ}$

The diffraction angle is:

$2 \theta=2\left(28^{\circ}\right)=56^{\circ}$

16.4 mL of 0.135 M NaOH is used to neutralize 46.9 mL of HCl. The concentration of the HCl solution is ____ M (3 decimal places)

marshall27 [118]

The concentration of the HCl solution is 0.047 M.

Explanation:

Data given about acid and base:

volume of acid Vacid = 46.9 ml

molarity of acid =?

volume of the base (NaOH) = 16.4 ml

molarity of the base = 0.135 M

To know the concentration of the acid in this reaction, the formula used in titration is used. It is

Macid X Vacid = Mbase X Vbase

the formula is rewritten as:

Macid = $\frac{Mbase X Vbase}{Vacid}$

putting the values in the equation:

Macid = $\frac{0.135 X 16.4}{46.9}$

= 0.047 M

the concentration of the acid i.e HCl in the solution is of 0.047 M.

Why do alligators need a warm climate?

Reptile [31]

<span>The answer is B.They cannot produce enough heat to keep their bodies warm.

In order to survive, the alligators rely on warm weather, and they are most active when the environment is 82-92 degrees Fahrenheit. They can survive below or above this temperature range but they may spend that time struggling to stay warm or stay cool.
