is zinc a basic radical or acid radical?​

Answers

Answer 1

Answer:

depends on the element it's reacting with..

Explanation:

if the another element requires less energy to loose electron then zinc will become negatively charged and hence becomes acidic radical..

normally if it is reacting with element with valency 4 and Atomic number less than it(Ti,Si,C) then it will lose electron and gain positive sign and henve becomes basic radical..

The properties can be influenced by many factors. The most common are the shape of the object, the lighting where the object is located, the environment (colors, shapes, density of other objects, etc.), and the viewing angle of the observer.

how long would it take to electroplate a flute with 28.3 g of silver (107.87 g/mol) at a constant current of 2.0 amps using AgNO3

Answers

It would take 211 hours to plate 28.3 g of silver on a flute.

The equation of the reaction;

Ag^+(aq) + e -----> Ag(s)

We know that 1 F of electricity is required to deposit 107.87 g of Ag. Also 1F = 96500 C

Now;

Since  107.87 g is deposited by 96500 C of electricity

28.3 g is deposited by  28.3 g ×  96500 C/ 107.87 g

= 25317 C

Also;

Q = It

I = current

t = time

25317 C =  2.0 amps × t

t = 25317 C /2.0 amps

t = 12658.5 seconds or 211 hours

Answer:

It would take [tex]3.5hrs[/tex] to electroplate the flute

Explanation:

Electrolysis equation is:

[tex]Ag1+ + 1e- ------> Ag[/tex]

1 mol of Ag requires 1 mol of electron

1 mol of electron = 96485 C

So,

1 mol of Ag requires 96485 C

let us calculate mol of element deposited:

molar mass of Ag = [tex]107.87 g/mol[/tex]

number of mol of Ag, [tex]n = \frac{mass of Ag}{molar mass of Ag}[/tex]

[tex]n = \frac{28.3}{107.87}\\\\n = 0.2623 mol[/tex]

[tex]total charge = mol of element deposited * charge required for 1 mol\\\\total charge = 0.2623*9.649*10^4\\\\total charge = 2.531*10^4 C[/tex]

Therefore,

[tex]time = \frac{Q}{i}\\\\= \frac{2.531*10^4}{2}\\\\= 1.265*10^4 seconds\\\\= 3.515 hr[/tex]

Answers

The electron configuration for the ion's neutral parent atom is

1s²2s²2p⁶3s²3p⁶4s²

It belongs to group 2 on the periodic table and one of its chemical properties is, it has a density of 1.54 g/cm³

From the question,

The cation has a charge of 2+. This means the neutral atom lost 2 electrons.

From the given electron configuration, the cation has 18 electrons.

Therefore, the neutral atom of ion will have 20 electrons.

∴ The electron configuration for the ion's neutral parent atom is

1s²2s²2p⁶3s²3p⁶4s²

The atom belongs to group 2 on the periodic table.

Answers

The correct answer is Sulfur Hexafluoride
it’s an inert gas that is known to be six times heavier than the air we breathe. While Helium being lighter makes our voice higher, SF6 makes our voice deeper. The sound travels slower in denser gases which is why our voice will come out deeper and rather slow.

Gaseous chlorine, Cl2, was combined with 0.532g of Titanium, and 2.108 g of TixCly were collected. What is the empirical formula of titanium chloride?

Answers

Answer:

TiCl₄

Explanation:

From the law of conservation of mass, the mass of the reactants must equal the mass of the products. In other words:

[tex]\displaystyle \text{m Cl$_2$} + \text{ m Ti} = \text{ m Ti$_x$Cl$_y$}[/tex]

Find the mass of chlorine gas reacted:

[tex]\displaystyle \begin{aligned} \text{ m Cl$_2$} + (0.532 \text{ g}) & = (2.108 \text{ g)} \\ \\ \text{m Cl$_2$} & = 1.576 \text{ g} \end{aligned}[/tex]

Find the number of moles of each reactant using their respective molecular weights:

[tex]\displaystyle 1.576 \text{ g Cl$_2$} \cdot \frac{1 \text{ mol Cl$_2$}}{70.90\text{ g Cl$_2$}} \cdot \frac{2\text{ mol Cl}}{1\text{ mol Cl$_2$}} = 0.04446\text{ mol Cl}[/tex]

And:

[tex]\displaystyle 0.532\text{ Ti} \cdot \frac{1\text{ mol Ti}}{47.87\text{ g Ti}} = 0.0111\text{ mol Ti}[/tex]

To find the empirical formula, all values by the smallest value:

[tex]\displaystyle \begin{aligned} \frac{0.0111\text{ mol Ti}}{0.0111} & = \frac{0.04446\text{ mol Cl}}{0.0111} \\ \\ 1\text{ mol Ti} & \approx 4\text{ mol Cl}\end{aligned}[/tex]

Hence, there are four moles of chlorine for every one mole of titanium.

In conclusion, our empirical formula is TiCl₄.

how many neutrons of atomic mass is 31 and atomic number is 12

Answers

[tex]▪▪▪▪▪▪▪▪▪▪▪▪▪  {\huge\mathfrak{Answer}}▪▪▪▪▪▪▪▪▪▪▪▪▪▪[/tex]

As we know, Number of protons = Atomic Number

So,

Number of protons = 12

therefore ~

31 = 12 + N

N = 31 - 12

N = 19

Number of Neutrons = 19

A sample of ethanol (C2H6O) has a mass of 0. 2301 g. Complete combustion of this sample causes the temperature of a bomb calorimeter to increase by 1. 33°C. The calorimeter has a mass of 2. 000 kg and a specific heat of 2. 45 J/g•°C. What is the heat of combustion for this sample? kJ.

Answers

The heat of combustion of the sample is calculated to be  -1300 kJmol-1.

We know that energy is neither created nor destroyed but is converted from one form to another. The heat lost by the ethanol when it is burnt is equal to the heat gained by the calorimeter.

Heat gained by calorimeter =  2.×10^3 g ×  2. 45 Jg-1°C-1 × 1. 33°C

= 6.5 kJ

Number of moles of ethanol =  0. 2301 g/46 g/mol = 0.005 moles

A force of 5N accelerates an object. The object mass is 50 g. What is the acceleration of an object?

Answers

Answer:

100 m/ s²

Explanation:

Newton's Second Law of Motion:

[tex] \boxed{ \mathsf{force = mass \times acceleration}}[/tex]

___________________

In the question:

Force applied = 5 N mass of the object experiencing force = 50 g

Note that the quantities here must be in their SI units.

SI unit of Force is Newton(N).

SI unit of mass is kilogram(kg)

Force is already in it's SI unit, while mass isn't.

Converting mass from grams to kilograms:

1000 g = 1 kg

=> 1 g = 1/ 1000 kg

=> 50 g = 50/ 1000 kg

= 1/ 20 kg

___________________

Calculating acceleration:

[tex] \mathsf{5 = \frac{1}{20} \times acceleration }[/tex]

multiplying both sides by 20:

[tex] \implies \mathsf{5 \times 20= (\frac{1}{20} \times 20)\times acceleration }[/tex]

20 on the RHS gets canceled, for it's present on the numerator as well as the denominator.

[tex] \implies \mathsf{100= acceleration }[/tex]

So, here, we got acceleration = 100 m/s².

Since, the other quantities used in the formula are in their SI units, acceleration must be in it's SI unit as well.

The SI unit of acceleration is m/s²
