Why are all organs are in the alimentary canal important in digesting food

k0ka [10]

The organs in the alimentary canal are important to digestion because they work together to move food and waste through the body. Without them, food wouldn't be able to move to their correct organs to digest and provide nutrients & energy, and waste would not be able to get out of the body.

The solubility of acetanilide is 0.53 g in 100 mL of ice‑cold water, and 5.50 g in 100 mL of boiling water. What is the maximum

GrogVix [38]

Answer:

MPR=90,36%

Explanation:

The recrystallization is a purification process where the solid to purify is dissolved in an appropriated dissolvent and then, changing the conditions the solubility changes and that solid (that was in solution before) precipitates and form crystals.

In this case, for boiling water 5.50 g of acetanilide could be dissolved and then cold the water, so the mass of crystals formed will be

$m_{crystal}=\left(5.5-0.53\right)g=4.97g$

The maximum percent recovery is then

$MPR=\frac{mass\ of\ solid\ recovered}{mass\ of\ solid\ disolved}\times 100\% = \frac{4.97g}{5.5g}\times 100\%=90,36\%$

A buffer solution is prepared by adding 13.74 g of sodium acetate (NaC2H3O2) and 15.36 g of acetic acid to enough water to make

hoa [83]

Answer:

A buffer solution is prepared by adding 13.74 g of sodium acetate (NaC2H3O2) and 15.36 g of acetic acid to enough water to make 500 mL of solution.

Calculate the pH of this buffer.

Explanation:

The pH of a buffer solution can be calculated by using the Henderson-Hesselbalch equation:

$pH=pKa+log\frac{[salt]}{[acid]}$

The pH of the given buffer solution can be calculated as shown below:

A certain compound is made up of one phosphorus (P) atom, three chlorine (Cl) atoms, and one oxygen (O) atom. What is the chemic

zzz [600]

Ok so we know that all of these are non metals therefore they will bond using covalent bonds.
Phoshorus can have 3 bonds Chlorine can have 1 bond and Oxygen can two bonds.
Cl-P=O
The chemical formula I belive is PClO hope this helps :).
