To see the number of atoms of an element in a given molecule we need to multiply stoichiometry to the number that is written on the foot of the element that is stoichiometry. Therefore, the number of protons always equals the number of electrons. The correct option is option 1.

Atom is the smallest particle of any element, molecule or compound. Atom can not be further divided. Atoms contains nucleus in its center and electron that revolve around the atom in fixed orbit.

In the nucleus, proton and neutron are present. Electron has -1 charge while proton has +1 charge. Neutron is neutral that is it has no charge. So overall the charge of nucleus is due to only proton, not by neutron. The number of protons always equals the number of electrons.

Therefore, the number of protons always equals the number of electrons. The correct option is option 1.

After the initiation of mechanical ventilation, we observe Increased pH.

Mechanical ventilation is a type of life support that involves the use of positive pressure to help a patient breathe. Respiratory therapists work closely with doctors to provide care for patients who are intubated and connected to a ventilator. The most important aspect of this process is monitoring the patient-ventilator interaction to ensure that they are receiving the right amount of support. Vital signs are a key part of any patient assessment. In mechanically ventilated patients, it is important to monitor the following:

Heart rate

A substance's malleability depends on how elastic it is. A metal becomes more malleable as it becomes more elastic.

Metals are able to be bent and moulded because they are malleable. They are layers of atoms, which is why. When the metal is pressed, bent, or hammered, these layers can glide over one another. While rolling over one another, the atoms can nevertheless maintain the crystal's structure.

Metals are referred to as ductile (can be formed into sheets) and malleable (can be pulled out into wires). The capacity of the atoms to roll over one another into new places without rupturing the metallic bond is the reason for this.

DNP is integrated into mitochondrial membranes, electron transport is gradually inhibited. Dinitrophenol (DNP) is an uncoupler, which means it may separate the pumping of H+ ions for ATP production from the flow of electrons.

Without affecting the respiratory chain or ATP synthase (H(+)-ATPase), uncoupler of oxidative phosphorylation in mitochondria prevent the coupling between the electron transport and phosphorylation reactions. This inhibits ATP synthesis.

DNP is known to have mixed activities, which means that in addition to uncoupling, it also has other effects. This implies that ATP production is not possible using the energy from electron transport.

Then 74.8 % is  the percentage yield of the reaction.

The percentage yield indicates the amount of product received in relation to the maximum feasible mass. The percentage of atoms in reactants that create the intended product is given by the atom economy of a reaction.

In industrial chemistry, the percentage yield of a chemical process is an essential factor. It is possible to compute the yield (amount) of product obtained vs what might have been achieved in theory if all of the reactants were converted without loss or waste.

Given reaction:

2Mg(s)+O₂(g) → 2MgO(s)

42.5 gm of Mg = 42.5 / (24 g/mol)

                         = 1.77 mol

33.8 gm of O₂ = 33.8 gm / (32 g/mol)

                       = 1.06 mol

1.06 moles of O₂ will require (2 × 1.06) = 2.12 moles of Mg

But we have 1.77 moles of Mg, so here Mg is limiting reagent.

1.77 moles of Mg reacts with (1.77/2) = 0.89 moles of O₂ and forms 1.77 moles of MgO

Thus, theoretical yield of mass = 1.77 moles × (40 gm/mol)

                                                   = 70.8 gm

Actual yield = 52.7 gm of MgO.

So, Percentage yield = (Actual yield / theoretical yield) × 100

                                   = (52.7 gm /70.8 gm) × 100

C = k*P —————-(1)

where k = the constant of Henry

The following is true:

CO2 concentration C = 0.1 mol/L k for CO2 at 25 C = 3.4 * 10-2 mole/L atm

In accordance with eq(1),

p(CO2) = C/k
