Answer:

Volume of AgNO₃ = 4.9 ml (Approx)

Explanation:

Given:

Total solution = 75 ml

Volume of AgNO₃ = 6.5%

Find:

Volume of AgNO₃

Computation:

Volume of AgNO₃ = Total solution x Volume of AgNO₃

Volume of AgNO₃ = 75 x 6.5%

Volume of AgNO₃ = 4.875

Volume of AgNO₃ = 4.9 ml (Approx)

Answer:

This question appear incomplete

Explanation:

This question appear incomplete because of the absence of the value of the count of the ions inside the unit cell. To determine the mass (in grams) of LiCl in a unit cell, the formula below can be used

count of ions inside the unit cell = mass of LiCl ÷ molar mass of LiCl

Hence,

Mass of LiCl = count of ions inside the unit cell × molar mass of LiCl

Count of ions (Li⁺ and Cl⁻ ions specifically) inside the unit cell should have been provided in the question

Molar mass of LiCl was given to be 42.39 g/mol

The mass of the LiCl unit cell has been 2.82 [tex]\rm \bold{\times\;e^-^2^2}[/tex] grams.

The given structure has been the unit cell of the LiCl having 4 atoms of Li and 4 atoms of Cl.

The number of Li and Cl in a molecule of LiCl has been 1, and 1 respectively.

The presence of 4 atoms of Li and Cl indicates that there has been the presence of 4 molecules of LiCl.

The molar mass ofLiCl = 42.39 g/mol.

The number of molecules present in a mole of the sample has been equivalent to the Avagadro number.

6.023 [tex]\rm \times\;10^2^3[/tex] molecules = 1 mole LiCl.

6.023 [tex]\rm \times\;10^2^3[/tex] molecules = 42.39 grams LiCl.

The mass of 4 molecules of LiCl has been:

4 molecules = [tex]\rm \dfrac{42.39}{6.023\;\times\;1^2^3}\;\times\;4[/tex]

4 molecules = 2.82 [tex]\rm \times\;10^-^2^2[/tex] grams

2.82 [tex]\rm \times\;10^-^2^2[/tex] grams =  2.82 [tex]\rm \bold{\times\;e^-^2^2}[/tex] grams.

The mass of the LiCl unit cell has been 2.82 [tex]\rm \bold{\times\;e^-^2^2}[/tex] grams.

Explanation:

Answer:742 torr= approximately 0.976 atm

Explanation:

Since we know that one atm= 760 torr, we can compute the following calculation:

(742 torr/1)*(1atm/760torr)=0.976316 atm

Remember sig figs (3) to round it to 0.976 atm

[tex]\frac{742 torr}{1}[/tex]*[tex]\frac{1 atm}{760 torr}[/tex]=0.976316=0.976 atm

(torr cancels out and we're left with atm)

Hey there.. the question is not proper. Please give the whole question

The temperature : 332.75 K

Conditions at T 0 ° C and P 1 atm are stated by STP (Standard Temperature and Pressure). At STP, Vm is 22.4 liters / mol.

Barium forms cation : Ba²⁺

Given

Barium element

Required

Ion type

Solution

Barium with the symbol Ba is an alkaline earth metal element having the atomic number 56

Electron configuration of Barium: [Xe] 6s2

If we look at this configuration, then Barium will try to achieve stability by removing 2 electrons so that the electron configuration is the same as the noble gas Xenon (Xe)

Because it removes 2 electrons, Barium has the number of protons> the number of electrons so that the charge is positive and forms a cation

Answer:

See explanation

Explanation:

We must take into account the order of stability of free radicals. The order of stability of free radicals is;

Tertiary>secondary>primary> methyl.

As a result of this, structure 1 involving a tertiary radical leads to the more abundant product as shown.

Answer:

Lithium to form LiBr. An ionic bond is a type of chemical bond that involves a metal and a nonmetal ion.

So your correct answer would be B) Li

Answer:

They would use 15.17 g KNO₃.

Explanation:

To solve this problem first we calculate the number of KNO₃ moles that would be in the solution, multiplying the concentration times the volume:

750 mL ⇒ 750 / 1000 = 0.750 L

Then we convert moles of KNO₃ to grams, using its molar mass:

Answer:

The gain of an electron adds more electrons to the outermost shell which increases the radius because there are now more electrons further away from the nucleus and there are more electrons to pull towards the nucleus so the pull becomes slightly weaker than of the neutral atom and causes an increase in atomic radius.GOOD LESSONS ♡

Answer: In the periodic table, the atomic radius of elements tends to decrease as you move across a row from left to right. The number of protons increases left to right, leading to a greater attractive force in the nucleus.

Explanation: The stronger attraction pulls the electrons closer in, reducing the radius.

The mass of nitroglycerin : 34.52 g

Reaction

4C₃H₅N₃O₉ ⇒ 12 CO₂ + 10H₂O + 6N₂ +O₂
