Answer:

1.23 × 10³ N

Explanation:

Step 1: Given and required data

Step 2: Calculate the force acting between the Earth and a 125-kg person standing on the surface of the Earth

We will use Newton's second law of motion.

F = m × g

F = 125 kg × 9.81 m/s²

F = 1.23 × 10³ N

Answer:

6.46 × 10⁻¹¹ M

Explanation:

Step 1: Given data

pH of the solution: 3.81

Step 2: Calculate the pOH of the solution

We will use the following expression.

pH + pOH = 14.00

pOH = 14.00 - pH = 14.00 - 3.81 = 10.19

Step 3: Calculate the concentration of OH⁻ ions

We will use the definition of pOH.

pOH = -log [OH⁻]

[OH⁻] = antilog -pOH = antilog -10.19 = 6.46 × 10⁻¹¹ M

Answer: 1. 0.045moles

2.  2.10 grams

Explanation:

According to avogadro's law, 1 mole of every substance occupies 22.4 L at STP and contains avogadro's number [tex]6.023\times 10^{23}[/tex] of particles.

To calculate the moles, we use the equation:

[tex]\text{Number of moles}=\frac{\text{Given mass}}{\text {Molar mass}}[/tex]

1. [tex]\text{Number of moles of zinc nitrate}=\frac{8.51g}{189.36g/mol}=0.045moles[/tex]

2. Mass of [tex]C_2H_4=moles\times {\text {Molar mass}}=0.075moles\times 28.05g/mol=2.10g[/tex]

Answer:

Protons = atomic #

Neutrons = Mass # - atomic #

Electrons = atomic # - charge ( If no charge electrons = 0 therefore electrons = atomic # only if No charge not including the ^ number thing)

The element is Palladium

atomic number = 46.

Atomic Mass = 106

Therefore The answer being

Protons = 106

Neutrons = 60

Electrons = 104

( Sorry im only in the 9th grade but i did the best i could) The reason electrons are 104 is because of the 2+ meaning 2+ more protons than electons.

Answer: The new volume will be 1.5 L

Explanation:

The combined gas equation is,

[tex]\frac{P_1V_1}{T_1}=\frac{P_2V_2}{T_2}[/tex]

where,

[tex]P_1[/tex] = initial pressure of gas = 1 atm

[tex]P_2[/tex] = final pressure of gas = 1.1 atm

[tex]V_1[/tex] = initial volume of gas = 2 L

[tex]V_2[/tex] = final volume of gas = ?

[tex]T_1[/tex] = initial temperature of gas = [tex]130^0C=(130+273)K=403K[/tex]

[tex]T_2[/tex] = final temperature of gas = [tex]324K[/tex]

Now put all the given values in the above equation, we get:

[tex]\frac{1\times 2}{403}=\frac{1.1\times V_2}{324}[/tex]

[tex]V_2=1.5L[/tex]

The new volume will be 1.5 L

Answer:

Ionic bonding is the attraction between positively- and negatively-charged ions. These oppositely charged ions attract each other to form ionic networks (or lattices). Electrostatics explains why this happens: opposite charges attract and like charges repel.

Explanation:

Ionic compounds form because opposite charges attract.

In an ionic compound, positive and negative ions come together to form a stable structure. This occurs when an atom loses electrons to become a positively charged ion (cation) and another atom gains those electrons to become a negatively charged ion (anion). The positive and negative charges of the ions attract each other, resulting in the formation of an ionic bond.

This attraction between positive and negative charges is what holds ionic compounds together. The strong electrostatic forces of attraction between ions result in a lattice structure, where each ion is surrounded by oppositely charged ions.

Thus, ionic compounds are formed because opposite charges attract.

Mean: 350

Median: 300

Range: 650

Mode: 300

Explanation:

Mean: 800+300+150+300+200= 1750, 1750 divided by 5 = 350

You add up all the numbers then you divide it by the TOTAL NUMBER of NUMBERS to find the mean.

Median: (150, 200, 300, 300, 800)

To find Median put the numbers in order from greatest to least then you choose the middle number.

Range: Range is the distance from the smallest number to the largest the way to solve this is (Highest number) - (lowest number). In your case its 800-150 which equals 650

Mode: The mode is the value that appears most frequently in a data set.

C. The amount of product will be limited by the number of moles of

the limiting reagent.

Explanation:

a p e x :)) i just took the quiz

The amount of product will be limited by the number of moles of

the limiting reagent. Hence, option C is correct.

The reactant that gets consumed early in the reaction restricts the quantity of product which will be produced in the chemical reaction. Thus, the reactant that gets consumed early in a chemical reaction is a limiting reagent.

Hence, the amount of product will be limited by the number of moles of the limiting reagent.

Answer:

mNa₂C₂O₄ = 0.4489 g

Explanation:

This is a problem of stechiometry. in this case, we need to find the mole ratio between the permanganate solution and the oxalate. This can be seen in the balanced reaction which is the following:

2KMnO₄ + 8H₂SO₄ + 5Na₂C₂O₄---> 2MnSO₄ + 8H₂O + 10CO₂ + 5Na₂SO₄ + K₂SO₄

According to this balanced reaction, we have a mole ratio of 2:5 between permanganate and oxalate, so, the first thing to do here is calculate the moles of the permanganate needed to reach the endpoint of this titration:

n = M * V

Replacing we have:

nKMnO₄ = 0.0335 mol/L  * 0.040 L = 0.00134 moles

With these moles, and the above mole ratio, we can determine the moles of the oxalate:

2 moles KMnO₄ -------> 5 moles Na₂C₂O₄

0.00134 moles ---------> X

X = 0.00134 * 5 / 2

nNa₂C₂O₄ = 0.00335 moles

Finally, with the molecular mass of Na₂C₂O₄, we can determine the mass of the oxalate:

Molecular weights:

Na: 23 g/mol;   C: 12 g/mol;    O: 16 g/mol

MMNa₂C₂O₄ = (23*2) + (2*12) + (4*16) = 134 g/mol

mNa₂C₂O₄ = nNa₂C₂O₄ * MM

mNa₂C₂O₄ = 0.00335 * 134
