summarize how the VSEPR model helps explain how electric charges affect bonding and molecular shape in covalent compounds
The VSEPR model helps in explain how electric charges affect bonding and molecular shape in covalent compounds as -
The form of many molecules and polyatomic ions can be predicted using the valence-shell electron-pair repulsion (VSEPR) model, which is pronounced "vesper." However, keep in mind that the VSEPR model, like any model, is only a partial description of reality; it doesn't reveal bond lengths or the existence of numerous bonds.
The structures of many compounds and polyatomic ions with a central metal atom can also be predicted by the VSEPR model, as can the structures of practically any molecule or polyatomic ion with a central nonmetal atom. The foundation of the VSEPR theory is the idea that electron pairs in bonds and lone pairs reject one another and would, as a result, adopt a geometry that spreads them as far apart as feasible. The three-dimensional structures of many compounds, which cannot be predicted using the Lewis electron-pair approach, can be predicted using the straightforward VSEPR counting procedure, despite the fact that this theory is oversimplified and does not take into account the subtleties of orbital interactions that influence molecular shapes.
By concentrating only on the number of electron pairs surrounding the central atom and disregarding any other valence electrons present, the VSEPR model can be used to predict the geometry of the majority of polyatomic compounds and ions. This model states that valence electrons in the Lewis structure form groups that can be made up of a single bond, a double bond, a triple bond, a lone pair of electrons, or even a single unpaired electron, which is treated as a lone pair in the VSEPR model. Electrostatic repulsion causes electrons to repel one another; hence, the arrangement of electron groups that minimises repulsions is the most stable (lowest energy). The arrangement of groups around the centre atom creates the molecular structure with the lowest energy
The molecule or polyatomic ion is designated by the letters AXmEn in the VSEPR model, where A stands for the centre atom, X for a bonding atom, E for a nonbonding valence electron group (often a lone pair of electrons), and m and n are integers. The designation of each group surrounding the centre atom as a bonding pair (BP) or lone (nonbonding) pair (LP). Both the relative locations of the atoms and the bond angles—also known as bond angles—can be predicted from the BP and LP interactions. We may characterise the molecular geometry—the configuration of the bound atoms in a molecule or polyatomic ion—using this knowledge.

So input, -log(2.27X10^-3) and it gives us 2.644 (appx.)
according to the pH chart, pH value lesser than 7 refer to acidic substances. pH value 7 means neutral and pH value higher than 7 means basic. As 2.644 is less than 7, so it is acidic.
3) Consider the ideal gas equation, PV = nRT. Rearrange to solve for P (show your work below).

The slope of the line would be m = nRT.
How to prove this answer?
We know that the ideal gas law is PV = nRT.
We know that y = mx + b. In that case, plotting y vs x gives you a slope
of m and an intercept of b.
Here according to the question, If we send V to RHS,
P= (1/V) nRT Where y axis is P and 1/V is y axis, nRT would be the ultimate slope.

Here given..
98 % of H2SO4 that means 98 g of H2SO4 is there in 100 g of aq. H2SO4 solution.
So.
Mass of solute = 98 g
Mass of solvent = 2 g (as water is considered as universal solvent)

Neither can be measured with any level of certainty at the same time.
Only one can be measured with some level of certainty at a given time.
Both can be measured with a low level of certainty at the same time.
Both can be measured when a high level of certainty at the same time.
Answer:
Both can be measured with a low level of certainty at the same time.
it depends on what you count as low or high levels of uncertainty though.
Explanation:
The equation is something like:
[tex]\Delta x \Delta p \geq \frac{h}{4 \pi}[/tex]
delta x is the uncertainty (not change) of position, and delta p is the uncertainty of momentum. then term on the right is a constant (in this case, a very small number)
This equation tells us that neither the uncertainty of position nor the uncertainty of momentum can be zero, which means that there will always be some uncertainty. However, we can note that both of the uncertainties can be quite small at the same time, they just can't be smaller than h/4pi. This means that both can be measured with a fairly high level of certainty at the same time. However, there is a limit of how high the values can be, so i would expect that the answer your teacher is looking for is that both can be measured with a low level of certainty at the same time. This is always true, as opposed to saying that both can be measured when a high level of certainty at the same time, since high is quite subjective

The temperature T₂, in Celsius, that is needed to reach the pressure of 7350 torr is 2517 °C
How do I determine the temperature T₂?From the question given above, the following data were obtained:
Initial pressure (P₁) = 735 torr Initial temperature (T₁) = 6 °C = 6 + 273 = 279 KVolume = ConstantNew pressure (P₂) = 7350 torrNew temperature (T₂) =?Since the volume isconstant, we can determine the new temperature, T₂ as illustrated below:

Cross multiply
735 × T₂ = 279 × 7350
Divide both side by 735
T₂ = (279 × 7350) / 735
T₂ = 2790 K
