Give the ideal bond angle for BrO3- ion? I know this has trigonal bipyramidal geometry and therefore the bond angle is < 109.
Vadim26 [7]

Now that we have a background in the Lewis electron dot structure we can use it to locate the the valence electrons of the center atom. The valence-shell electron-pair repulsion (VSEPR) theory states that electron pairs repel each other whether or not they are in bond pairs or in lone pairs. Thus, electron pairs will spread themselves as far from each other as possible to minimize repulsion. VSEPR focuses not only on electron pairs, but it also focus on electron groups as a whole. An electron group can be an electron pair, a lone pair, a single unpaired electron, a double bond or a triple bond on the center atom. Using the VSEPR theory, the electron bond pairs and lone pairs on the center atom will help us predict the shape of a molecule.

The shape of a molecule is determined by the location of the nuclei and its electrons. The electrons and the nuclei settle into positions that minimize repulsion and maximize attraction. Thus, the molecule's shape reflects its equilibrium state in which it has the lowest possible energy in the system. Although VSEPR theory predicts the distribution of the electrons, we have to take in consideration of the actual determinant of the molecular shape. We separate this into two categories, the electron-group geometry and the molecular geometry.

A sealed flask containing 1.0 mole of H2(g) and a sealed flask containing 2.0 moles of He(g) are at the same temperature. The tw
irinina [24]

Answer:

Pressure or Average Kinetic Energy

Explanation:

When dealing with sealed containers filled with gas, there are many variables to consider. Namely: pressure, temperature, volume, number of molecules present.

However, this question can be solved easily, without worrying too much about the other variables. Usually the case is that if there is a difference in pressure, there will be a difference in temperature, so the answer could be that both pressures must be equal.

Another way we could look at it is that the Average Kinetic Energies between the two containers have to be equal, and this will then lead to the temperatures being equal without worrying about other variables.

What does the law of conservation of energy imply?
zheka24 [161]

Answer:

B. That energy can only be converted between different forms

Explanation:

The law of conservation of energy implies that energy can only be converted between different forms but can neither be created nor destroyed.

Energy is the ability to do work. It is very important physical quantity that is essential to all life forms.

Energy according to the law of conservation of energy is not produced neither is it destroyed.

Energy is simply transformed from one form to another.

What is the concentration of a solution in which 10.0 g of AgNO3 is dissolved in 500 mL of solution?
Zigmanuir [339]

molar concentration of AgNO₃ solution = 0.118 mole/L

Explanation:

Because we have the volume of the solution and there is no information about the density of the solution I will asume that you ask for the molar concentration.

number of moles = mass / molecular weight

number of moles of AgNO₃ = 10 / 170 = 0.0588

molar concentration = number of moles / volume (L)

molar concentration of AgNO₃ solution = 0.0588 / 0.5

molar concentration of AgNO₃ solution = 0.118 mole/L
