Answer:

yes

Explanation:

because of high positive charge of Nb6+ delta G is more negative for Nb6+ as an oxidising agent♡

Answer:

So Sn2+ is a reducing agent (oxidises itself to Sn4+ hence becoming stable) while Pb2+ is already stable so it neither undergoes oxidation nor reduction.

Answer:

leading zeroes to the left of a decimal point. and trailing zeros to the left of an invisible decimal point.

Explanation:

In modern times, we know that the elements in a given group (also known as a family or column) have the same number of valence electrons, with ground state configurations having a consistent pattern, for instance:

F 1s2 2s2 2p5, Cl 1s2 2s2 2p6 3s2 3p5, Br 1s2 2s2 2p6 3s2 3p6 3d10 4s2 4p5, etc.

Of course, the ground state configurations play a major role in determining how an element reacts and what compounds it forms. Thus, the elements in a given group have similar properties.

The structure of the table also predicts how the properties vary. For instance, atomic radius increases down a group as does metallic character.

Explanation:

Answer: When they do, they transfer some of their energy. The energy is transferred from particle to particle. It is sort of like a row of dominoes falling over. In this process, thermal energy moves through a substance. It can even move into other nearby substances. In Figure above, conduction occurs between particles of the metal in the pot. It also occurs between particles of the pot

We can tell by how the continents look. Scientists who propose the pangea theory have said this. You can see for yourself because all the continents look like puzzle pieces you could put together. Scientists can also tell from the species. For example, let's say a scientist found a bone of a creature at the edge of a continent, the edge of another would have the same species. They have also calculated that the continents in itself are still splitting apart, but very slowly. The reason they split up was because tectonic plate movements.

Answer:

250 ml

Explanation: I got it right on the lab.

The size of the volumetric flask that would you use to create a 1.25 M solution using 29.75 g of MgCl₂ is 250mL.

How do we calculate volume of the solution?

Volume (V) in liter of the solution will be calculated by using the molarity (M) formula as:

M = n/V, where

n is the moles of the solute and it will be calculated by using mass as:

n = W/M, where

W = given mass

M = molar mass

Moles of 29.75g of MgCl₂ = 29.75g / 95g/mol = 0.313 mol

Given that molarity of solution = 1.25M

On putting values on the equation of molarity we will get the value of volume as:

V = 0.313 / 1.25 =  0.2504 L = 250mL

For the preparation of 250 mL of MgCl₂ solution we required the volumetric flask of 250 mL.

Hence volumetric flask of 250mL is required.

This means that the mass of one methane molecule is 12.011 u + (4 × 1.008u), or 16.043 u. This means that one mole of methane has a mass of 16.043 grams. A mole can be thought of as two bags of different sized balls. One bag contains 3 tennis balls and the other 3 footballs.

Samples of helium (He), nitrogen (N 2 ), and methane (CH 4 ) are at STP. Each contains 1 mole or 6.02 × 10 23 particles. However, the mass of each gas is different and corresponds to the molar mass of that gas: 4.00 g/mol for He, 28.0 g/mol for N 2 , and 16.0 g/mol for CH 4 .

Answer:

13.7 degrees.

Explanation:

Answer:

Value for K would be too small. Less AgCl would dissolve due to the common ion effect due to the presence of Cl- in the water.

Explanation:

Think of this through the lenses of a shifting problem. Cl- ions are a product in this situation and increasing its concentration would shift the reaction back to the solid AgCl. In this specific case, due to Cl- ions, AgCl would dissolve less to maintain equilibrium and as a result, the concentrations of Ag+ and Cl- ions would be lower than normal making a smaller K value.

In the solution of AgCl in tap water, the dissociation constant K has been decreased.

The dissolution of silver chloride in water results in the formation of silver ions and chloride ions.

The dissociation constant has been the amount of compound that has been dissociated into the constituent ions at equilibrium.

The dissociation constant has been dependent on the number of ions in the solution that has been present.

The common ion effect has been defined as the change in the dissociation constant for the compound with the presence of common ions in the solution.

The dissociation of AgCl in tap water has been resulted with presence of Cl ions in the solution. There has been early reach to the equilibrium in tap water.

Thus, with the solution of AgCl in tap water, the dissociation constant K has been decreased.

Answer:

Sam's average speed  = 2.22 m/s

Explanation:

The average speed refers to the speed with which a distance is covered within a particular time duration. The average speed of a moving object can be obtained by summing up all the varying speeds as the object moves from one point to another, within a particular time frame.

Sams average speed can be calculated using this formula:

Average speed = distance / time

Distance covered = 2000 meters

Time taken to cover the distance = 9:15 am - 9:00 am = 15 minutes = 15 X 60 seconds = 900 seconds

Sam's average speed = 2000meters / 900 secs = 2.22 m/second
