What is the acceleration of a 0.30-kilogram ball that is hit with a force of 50 N?

Resonance structures are various forms of the same molecule in which electrons have moved from one region to another.

I. Structure

Both the carbon (C) atoms have a formal charge of = 4 valance - bonds = 0.

Formal charge (O) = 6 volts equivalence - 2 bonds - 4 nonbonding electrons = 0

Formal charge on (N) = 5 volts equivalence - 3 bonds - 2 nonbonding electrons = 0

V.E. - 1 bond = 0 F.C. on H = 1

Overall molecule charge will be = 0 charge

II. Structure

Formal charge on both C atoms equals 4 valence minus 4 bonds = 0

Formal charge (O) = 6 V.E. minus 1 bond minus 6 nonbonding electrons = -1 charge

Formal charge on (N) = 5 V.E. - 4 bonding electrons - 0 nonbonding electrons = +1 charge

V.E. - 1 bond = 0 F.C on H = 1

Overall molecule charge = +1 -1

The electron configuration of the gallium (III) ion (Ga^3+) is [Ar] 3d^10 .

The electron configuration of an atom or ion describes the distribution of electrons in the energy levels (shells) and sublevels (orbitals) of the atom or ion.

When an atom loses one or more electrons, it becomes a cation (positively charged ion). In the case of the Ga^3+ ion, it has lost three electrons, so it's electron configuration would be left with the remaining 10  in theeir 3d^10 sublevels.

It's also important to notice that electron configurations are written in a way that follows the Aufbau principle, Hund's rule and Pauli Exclusion principle which are used to predict the most stable configuration for an atom or an ion.

Answer:

Matter is NOT being created

Explanation:

There's a fundamental law of conservation of mass and energy which states we CANNOT create new mass or energy, we can just rearrange stuff.

I went to your PHET lab and one thing you could do to prove it is show that you react two h2 and two O2 in process of making water. You will see on the box on the right that you get two water molecules and a leftover H2. Now count up the number of atoms of each element on both sides.

In left side with reactants, you have 2 H2 (so a total of 4 hydrogen atoms), and 2 O2 (so a total of 4 oxygen)

In right side with product and leftover, you have two water molecule (each water molecules has two hydrogen and one oxygen so total you have 4 hydrogen and two oxygen since you ahve two water molecule). But you also have one O2 left over (that's two oxygen atoms)

Now see the magic, we started with 4 hydrogen atoms and 4 oxygen atoms

We ended with 4 hydrogen atoms and 4 oxygen atoms!!

NO MATTER was created, the atoms were just rearranged. Does that make sense?

1 / 102.0 g/mol is the correct way to write the inverted molar mass of aluminum oxide as a conversion factor.

The molar mass is defined as the mass of a given chemical component or chemical agent (g) multiplied by the amount of things (mol). The standard atomic weights (in g/mol) of a compound's constituent atoms can be multiplied to determine its molar density. A solid's molar mass is a bulk characteristic rather than a molecular one.

The molar mass of aluminum oxide is 102.0 g/mol.

1 mol Al₂O₃ = 102.0 g

=> 1 = 1 mol Al₂O₃  / 102.0 g = 1 / 102.0 g/mol

2) [tex]Mg^{2-} > Mg > Mg^{2+}[/tex]

3) [tex]Sb^{3-} > Te^{2-} > I^{-} > Cs^{+1} > Ba^{2+} > La^{3+}[/tex]

There are two primary trends in atomic radius. One atomic radius trend appears as you walk across the periodic table from left to right (doing so within a period), and the other trend appears as you move from the periodic table's top down (moving within a group).

In other words, as protons are added, the nucleus gains a higher positive charge, which in turn attracts the electrons more strongly and draws them in toward the nucleus of the atom. The radius of the atom decreases as the electrons are drawn inward toward the nucleus.

The atom gains one extra electron shell for every group down. The atomic radius grows when each additional shell is positioned farther from the atom's nucleus.

According to the question

for the first point all the atoms are in the period so the order will be,

[tex]Po^{2-} > Te^{2-} > Se^{2-} > S^{2-} > O^{2-}[/tex]

and in the second point Mg is losing electrons. more it lose the electrons, less will be the radius.

When 10 mL of 0.1 N HCl is added to 990 mL of a solution of NaCl, the resulting solution will be a mixture of HCl and NaCl. The pH of this solution can be determined by considering the acid-base behaviour of HCl and the concentration of H+ ions in the solution.

HCl is a strong acid, meaning that it fully dissociates in water to form H+ ions and Cl- ions. Therefore, the addition of HCl will significantly increase the concentration of H+ ions in the solution.

The concentration of H+ ions in the resulting solution can be calculated using the formula:

[H+] = (0.1 N) * (10 mL) / (1000 mL) = 1.0 x 10^-3 M

The pH of a solution can be calculated using the formula:

pH = -log[H+]

Plugging in the value of [H+] we got above:

pH = -log(1.0 x 10^-3) = -(-3) = 3

The conditions which can result in deviations from Beer's law when the path length is constant are:

The Beer-Lambert Optical Law is a relationship where the absorption of light is linked to the properties of a material by connecting the intensity of the incoming light and the intensity of the outgoing light. The law explains that the absorbance is dependent on the length traversed by the light, the concentration of the absorbent in the medium, and the absorption coefficient.

So, in this case, the correct condition is stray light reaching the detector. Since stray radiation is derived from Beer's law with the formula, this is can be explained as follows:
