what does this mean for the number of energy storage molecules in the algae

PF₆ does not obey the octet rule.

The octet is broken in the PF₆-molecule because P increases its valency instead of adhering to it.

According to the octet calculation, it needs 56 electrons but only has 48 valence electrons, thus the missing 8 electrons are added up by 8/2 = 4 bonds. However, in this case, P forms six bonds, which is against the octet rule.

For each atom in a Lewis structure, you should count how many electrons it "owns" in order to get the formal charges.

All of its lone pair electrons as well ashalf of its bonding electrons should be counted.

The formal charge is the discrepancy between the atom's number of valence electrons and the number it possesses. The concept that an atom's valence electrons should be eight in order for a molecule made up of carbon, nitrogen, oxygen, and fluorine to be more stable is known as the "octet rule." When one of these atoms has fewer than eight valence electrons, an open octet is present. Lewis structure attached below

The partial pressure of oxygen in the mixture if the total pressure is 705 mmHg is 427.935 mmHg

mO2 =100g - 35.8% = 64.2 g

We shall use the molar masses of both masses to convert them to moles.

N2 = 35.8*1mol/28.00=1.29mol

O2=64.2, *1 mol/32.00, or 2 mol.

O2's mole fraction is:

O2 = nO2 + nN2 + nO2 = 2/ 1.29 + 2 = 0.607

We can use the following expression to determine the partial pressure of oxygen given the total pressure (P) is 705 mmHg.

In a thermodynamics experiment, filtering the hot calcium hydroxide solution is necessary to removes any impurities or particulates that may be present in the solution that can affect the outcome of the experiment by introducing errors in the results.

In addition to this, filtering the hot calcium hydroxide solution also helps to ensure that the concentration of the solution remains consistent throughout the experiment. This is important because the concentration of the solution affects the thermodynamic properties of the solution, such as the temperature at which the reaction occurs. Without filtering, the concentration would vary depending on the amount of impurities present, and this could lead to inaccurate results.

Finally, filtering the hot calcium hydroxide solution also helps to prevent clogs or blockages in the equipment used for the experiment. If impurities are able to pass through the equipment, it could cause a disruption in the flow of the solution, which could affect the accuracy of the experiment.

what is NAOH?

The inorganic compound NaOH is sodium hydroxide, sometimes referred to as lye and caustic soda. The sodium cations Na+ and the hydroxide anions OH make up this white solid ionic combination.

Proteins are broken down by sodium hydroxide, a very caustic base and alkali that can result in serious chemical burns and is extremely reactive with proteins at room temperature. Easily absorbing moisture and carbon dioxide from the air, it is extremely soluble in water. NaOH and nH2O are formed in a sequence.

 Water solutions between 12.3 and 61.8 °C crystallize the monohydrate NaOH, H2O. This monohydrate is frequently the "sodium hydroxide" sold commercially; therefore, the anhydrous compound may not always be used when referencing it in published data.

Volume of H3PO4 =1.25l

Number of moles of H3PO4=0.525*1.25=0.66moles of H3PO4

NAOH is used to neutralize the solution.

H3PO4+3NAOH ⇒ NA3PO4+H2O

3 moles of NAOH react with one mole of H3PO3. So, the number of moles of NAOH is equal to 3 times of number of moles of H3PO4
