What ion do acids release in solution?

wariber [46]

Answer: $H^+$

Explanation: All the Arrhenius and Bronsted Lowry acids release $H^+$ ions in solution.

According to Arrhenius and Lowry, acids are substances which release $H^+$ ions when dissolved in water.

Thus $HCl, H_2SO_4 and H_3PO_4$ all are considered as acids,

$HCl\rightarrow H^++Cl^-$

$H_2SO_$\rightarrow H^++SO_4^{2-}$

$H_3PO_4\rightarrow H^++PO_4^{3-}$

In yeast, ethanol is produced from glucose under anaerobic conditions. A cell‑free yeast extract is placed in a solution that co

nadezda [96]

Answer:

0.35 milli moles of ethanol can be theoretically be produced under these conditions.

Explanation:

$C_6H_{12}O_6 + 2 ADP + 2 Pi\rightarrow 2 C_2H_5OH + 2 ATP + 2 CO_2$

Moles of glucose = $3.50\times 10^2$ milli mole

Moles of ADP = 0.35 milli mole

Moles of Pi = 0.35 milli mole

Moles of ATP = 0.70 milli mole

As we can see that ADP and Pi are in limiting amount which means tat they are limiting reagent. So, the moles of ethanol produced will depend upon the moles of ADP and Pi.

According to reaction, 2 moles of ADP gives 2 moles of glucose.

Then 0.35 milli moles of ADp will give :

$\frac{2}{2}\times 0.35 mmol=0.35 mmol$ of ethanol

0.35 milli moles of ethanol can be theoretically be produced under these conditions.

Raw materials used in the manufacturing of indigenous soap

Harrizon [31]

Answer:

Fat

Alkali

Explanation:

Fat and alkali are the two primary raw materials needed to manufacture soap.

Sodium hydroxide or potassium hydroxide is generally used as an alkali. The use of alkali depends on the intended application of the soap.

Raw animal fat was used in the past but these days, processed fat is used in the soap manufacturing process. Vegetable fats ( e.g, palm oil, olive oil, coconut oil) are also being used in soap manufacturing.

Additives are also used to enrich the color and texture of the soap.
