Answer:

P2 = 19.2atm

Explanation:

Initial pressure (P1) = 16atm

Initial temperature (T1) = 340K

Final temperature (T2) = 408K

Final pressure (P2) = ?

This question involves the use of pressure law

Pressure law states that the pressure of a fixed mass of gas is directly proportional to it's temperature provided that volume is kept constant.

Mathematically,

P = kT, k = P / T

Therefore,

P1 / T1 = P2 / T2 = P3 / T3 = ......=Pn / Tn

P1 / T1 = P2 / T2

We need to solve for P2

P2 = (P1 × T2) / T1

Now we can plug in the values and solve for P2

P2 = (16 × 408) / 340

P2 = 6528 / 340

P2 = 19.2atm

The final pressure (P2) of the gas is 19.2atm

Vlad [161]

A more strong base is added until the equivalence point is reached. The ph of this solution at the equivalence point if the total volume is 57. 0 mill is 9.8

The potential of Hydrogen is what pH is formally known as. The negative logarithm of the concentration of H+ ions is known as pH. Thus, the definition of pH as the amount of hydrogen is provided. The hydrogen ion concentration in a solution is described by the pH scale, which also serves as a gauge for the solution's acidity or basicity.

The pH scale determines how acidic or basic water is. The range is 0 to 14, with 7 representing neutrality. Acidity is indicated by pH values below 7, whereas baseness is shown by pH values above 7. In reality, pH is a measurement of the proportion of free hydrogen and hydroxyl ions in water.

Use the Bohr-Rutherford model of the atom to explain how an insulator-differs from a conductor
GaryK [48]

Answer:

A conductor is a material that permits electrons to effortlessly go through it. Copper is a good conductor. Note that the valence shell has just a single electron.

While;

Materials that don't conduct are named insulators.(i.e. glass, porcelain, plastic, elastic. The covering on electrical wire is an insulator.)

Insulators don't conduct since they have a full or almost full valence shell and along these lines their electrons are firmly bound.

Explanation:

According to Bohr Rutherford model of Atom, An Atom contains three essential particles; Protons and neutrons that make up the nucleus and the electrons that circle or orbit the nucleus. The electrons circle the nucleus.

Which property do metalloids share with nonmetals
Vesnalui [34]

Answer:

Explained below

Explanation:

Metalloids are elements that possess properties between that of metals and non - metals or that have properties that a re a combination of those of metals and non - metals. Whereas a metal is one that conducts electricity and heat very well.

Now, the property they both share is that they both possess valence orbitals which are highly de-localized over macroscopic volumes, thereby allowing both of them to be conductors of electricity although it has to be said that Metalloids don't conduct electricity as much as metals.

What is the coefficient for H2O when the equation ? Ca(OH)2(aq) + ? H3PO4(aq) → ? Ca3(PO4)2(s) + ? H2O(ℓ) is balanced using the
kari74 [83]

Answer:

Coefficient of H_{2}O in the balanced equation with smallest possible integer is 6.

Explanation:

Unbalanced equation: Ca(OH)_{2}(aq.)+H_{3}PO_{4}(aq.)\rightarrow Ca_{3}(PO_{4})_{2}(s)+H_{2}O(l)

Balance Ca: 3Ca(OH)_{2}(aq.)+H_{3}PO_{4}(aq.)\rightarrow Ca_{3}(PO_{4})_{2}(s)+H_{2}O(l)

Balance PO_{4}  : 3Ca(OH)_{2}(aq.)+2H_{3}PO_{4}(aq.)\rightarrow Ca_{3}(PO_{4})_{2}(s)+H_{2}O(l)

Balance H and O: 3Ca(OH)_{2}(aq.)+2H_{3}PO_{4}(aq.)\rightarrow Ca_{3}(PO_{4})_{2}(s)+6H_{2}O(l)

Balanced equation: 3Ca(OH)_{2}(aq.)+2H_{3}PO_{4}(aq.)\rightarrow Ca_{3}(PO_{4})_{2}(s)+6H_{2}O(l)

So coefficient of H_{2}O in the balanced equation with smallest possible integer is 6.
