A cube of each of metal i placed in a cup of water, they both diplace the ame volume of water ,aying how i thi poible?

Answers

This is possible because the volume of water displaced by an object is determined by the volume of the object, not its weight or mass.

The cube of metal I and the cube of another metal both have the same volume, so they would displace the same volume of water. The principle of buoyancy states that the buoyant force on an object is equal to the weight of the fluid that is displaced by the object can be applied in here. Therefore, if two objects have the same volume, they will displace the same amount of fluid and experience the same buoyant force.

What is the molarity when 24 grams of lioh is added to 200 ml of water?

Answers

The molarity when 24 grams of LiOH is added to 200 ml of water is 4.2M.

What is molarity, for instance?

The moles of solute per liter of solution is measured as molarity. For instance, when table salt is dissolved in water, water serves as both the solution and the solute. Sodium chloride weights 58.44 grammes per mole. One molar solution, or 1M, is created by dissolving 58.44 grammes of sodium chloride in one liter of water.

What does Molality refer to?

The term "total moles of a solute contained in a kilogram of a solvent" is used to describe molality. Molal concentration is another name for molality. It is a measurement of a solution's solute concentration.

Determination of molarity:

The molarity of the given LiOH solution is found to be 1.99 mol/L or 1.99M.

Given weight = 20g

molar mass of lithium hydroxide = 7+16+1=24g

volume = 200ml = 0.2l

Number of mole (n) = given weight /molar mass of lithium hydroxide

n = 20/24 =0.84

Molality = Number of mole (n) /volume of solvent

molality = 0.84/0.2

= 4.2M

Answers

The correct answer is 107.9 g of Ag is produced from a reaction of 31. 75 gram of Copper.

How to calculate The Molar Mass?

Molar mass of a substance is the mass in grams of one mole of the compound. A mole is the measurement of the number of things, such as atoms, molecules, and ions, that are present in a substance. Any material has 6.022 x 1023 molecules in a mole, it is known as Avogadro's number . The mole is used to determine the size of the tiniest entities quantitatively, just as we use a standard value to quantify many things, such as 1 dozen = 12 items.

Formula - Molar mass = mass in grams/mole = g/mol

Molar mass of a substance can be calculated as:

Given,

n = W/M, where

W = required mass

M= molar mas

Given chemical reaction is:

Cu + 2AgNO₃ → Cu(NO₃)₂ + 2Ag

From the stoichiometry of the reaction,

1 mole of Cu = produce 2 moles of Ag

Given mass of Cu = 31.75g

Molar mass of Cu = 63.5g/mol

Moles of Cu = 31.75g / 63.5g/mol = 0.5 moles

0.5 moles of Cu = produce 2×0.5 = 1 mole of Ag

Molar mass of Ag = 107.9g/mol

Required mass of Ag = 1mol × 107.9g/mol = 107.9 g

If I have 3.7 moles of MgSO4 and 4.8 moles of NH3 which one is the limiting reactant?​

Answers

Answer:

To determine the limiting reactant, you need to compare the amount of each reactant with the amount required to react completely with the other reactant. The reactant that runs out first is the limiting reactant.

In this case, the balanced equation for the reaction between MgSO4 and NH3 is:

MgSO4 + 2 NH3 → Mg(NH2)2SO4

From the balanced equation, we can see that 1 mole of MgSO4 reacts with 2 moles of NH3. Therefore, 3.7 moles of MgSO4 will react with (3.7 moles)(2 moles NH3/1 mole MgSO4) = 7.4 moles of NH3.

4.8 moles of NH3 is less than 7.4 moles, so NH3 is the limiting reactant.

Which of the following forms of
Bromine has the LARGEST ionic radius?
A. Br
B. Br-
C. Br+

Answers

Answer:

B. Br-

Explanation:

Ionic radius is a way of measuring the size of an element or compound.

Ionic Radius

Ionic radius is defined as the distance between the nucleus of an atom and the outermost electron. In terms of the periodic table, ionic radius grows to the left and down. The largest element on the periodic table is Francium since it is the lowest element on the left side.

Effective Nuclear Charge

The ionic radius of cations (positive ions) is always smaller than the regular element. Also, the ionic radius of anions (negative ions) is always larger. This is due to effective nuclear charge. Effective nuclear charge is how attracted electrons are to the nucleus. As electrons are added, effective nuclear charge decreases as the shielding effect becomes larger. Additionally, as the negative charge increases, the positive charge has less pull. The opposite is true for cations.

Since the electrons are less attracted to the nucleus in anions, they spread out more. This causes the radius to increase. For this reason, Br- has the largest ionic radius out of the listed options.

Answers

Answer:

This answer makes an assumption noted in the Explanation.

1.772 moles of NO2

Explanation:

The balanced equation tells us that NO2 does not react with N2O5.  As written, the answer to the question is zero.

If the question is how many moles of NO2 are produced by 0.8861 moles of N2O5, then we can note that the equation promises us 4 moles NO2 per 2 moles N2O5.  That's a molar ratio of 4:2 (moles NO2/moles N2O5).

(0.8861 moles N2O5)*(4:2 (moles NO2/moles N2O5)) = 1.772 moles of NO2

Answers

The mole fraction of LiBr is 0.8946

Calculations for LiBr's mole fraction are as follows:

We are aware that the mole fraction or molar fraction is defined as the amount of a constituent (expressed in moles), ni, divided by the total amount of all the elements in the mixture (also indicated in moles, ntotal).

mole fraction = n/n overall

first we should calculate hw many gram the solution from the density

assume the volume is 1 L

so.

density = mass solution/ volume solvent

0.826 g/ml = mass/ 100mL

mass= 82.6 g

so the mole of the solution is

mole = mass/ mass molar

mole solution = 82.6 g / 41.05g/ mole = 2.012 mole

Then we can find the mole of LiBr from the concentration

molar= moles x volume

1.8 M = moles x 1 L

moles LiBr = 1.8 moles

thus,

mole fraction = n/ n total
