Gravitational pull is stronger when the person is closer to the planet.

The gravitational force is the fundamental force of the universe. Here the astronaut at position B will experience a stronger gravitational pull as compared to the astronaut at position A.

What is gravitational force?

The gravitational force is defined as the force of attraction between any two bodies is directly proportional to the product of their masses and is inversely proportional to the square of the distance among them.

F = G m₁m₂ / r²

The gravitational force decreases with the increase in the distance. So here distance of astronaut at position B which is closer to the planet experience greater gravitational pull.

C. Na+ + OH + H+ + Cl → H+ + OH' + Na+ Cl"
O D. OH + H+ → H20

Answers

Answer:

D. OH⁻ + H⁺ → H2O.

Explanation:

Hello!

In this case, since this problem provides the complete ionic equation by which the neutralization reaction between sodium hydroxide and sodium chloride is carried out:

[tex]Na^+(aq)+OH^-(aq)+H^+(aq)+Cl^-(aq)\rightarrow Na^+(aq)+Cl^+(aq)+H_2O(l)[/tex]

Thus, since sodium and chloride ions are the spectator ones, as they are at both reactants and products, they can be cancelled out to obtain the net ionic equation as shown below:

[tex]OH^-(aq)+H^+(aq)\rightarrow H_2O(l)[/tex]

Therefore, the answer would be D. OH⁻ + H⁺ → H2O.

The question is incorrect, the correct question is;

Carbon-14, which is present in all living tissue, radioactively decays via a first-order process. A one-gram sample of wood taken from a living tree gives a rate for carbon-14 decay of 13.6 counts per minute. If the half-life for carbon-14 is 5720 years, how old is a wood sample that gives a rate for carbon-14 decay of 11.9 counts per minute?

Answer:

C. 1.1 x 103 yr

Explanation:

A = count rate of the wood sample

Ao= count rate of a living tissue

t1/2= half life of C-14

t = time taken

From;

0.693/t1/2 = 2.303/t log Ao/A

0.693/5720 = 2.303/t log (13.6/11.9)

1.2 * 10^-4 = 2.303/t * 0.05799

1.2 * 10^-4 = 0.1336/t

t = 0.1336/1.2 * 10^-4

t = 1.1 x 103 yr

Nick needs 3.5 moles of sodium fluoride (NaF) for a solution he is mixing in the lab. How many grams of NaF does Nick need to measure out?​

Answers

Answer:

147 g

Explanation:

The number of moles of a substance is the ratio of the mass of the substance and the molar mass of that substance. Mathematically,

  mole = mass of substance/molar mass

In this case, Nick needs 3.5 moles of NaF, the molar mass of NaF is calculated as:

  23 + 19 = 42 g/mol (Note: Na = 23, F = 19)

Hence,

mass of 3.5 mole NaF = mole x molar mass

                              = 3.5 x 42 = 147 g.

Hence, Nick would need to measure out 147 g NaF using a suitable weighing balance.

Answers

Answer:

the answer is pH of 7 I don't no Hydrochloric hijinx work

The equation pH = -log [H+], the pH of a solution with a hydrogen ion concentration is 5. Hence option c is correct.

What is solution?

Solution is defined as a continuous variation of two or more substances in their relative proportions up to what is known as the limit of solubility. Light beams do not disperse in the presence of a solution. In contrast, a suspension of particles might result in Tyndall or Rayleigh scattering. The amount of heat that is released or absorbed during the dissolving process is known as the enthalpy change of solution.

pH is defined as a measurement of how basic or acidic aqueous or other liquid solutions are. A solution's pH is a significant indicator of its chemical composition. The pH can affect how readily available nutrients are, how biological processes work, how bacteria behave, and how chemicals behave.

pH = -log[H+]

pH = -log[1.0 x 10⁻⁵]

pH = 5

Thus, the equation pH = -log [H+], the pH of a solution with a hydrogen ion concentration is 5. Hence option c is correct.

Explanation:

In the case of a rigid rorator, i.e. two masses M1 and M2 placed on a rigid weightless rod, we start from the Schrodinger equation for two particles 1 and 2, and then we separate the movement of the center of masses. Give the formulas of both masses that we get as part of this procedure. Calculate these masses in atomic mass units for the HD molecule by approximating the masses H and D with their mass numbers.

Answers

Answer:

Masses in atomic mass units for the HD molecule by approximating the masses H and D with their mass numbers is explained below in complete detail.

Explanation:

Two volumes M1 and M2 are located on a rigid weightless rod in a rigid rotor position. Energy in a rigid rotator example: E = BJ(J+1) where, B = h/8pi2Ic, B is rotational regular, I is moment of inertia = ur2 where u is decreased mass = m1m2/m1+m2.

FOR HD MOLECULE: mass, u = mass of H*mass of D/mass of H + D. Atomic mass unit =1.67*10^-27 kg. So, u = 1*1.67*10-24 * 2*1.67*10-24 / 1.67*10-24+2*1.67*10-24 = 1.67*10-24*2/3 = 1.11*10-24 g.

A 0.98 gram sample of a volatile liquid was heated to 348 k. the gas occupied 265 ml of space at a pressure of 0.95 atm. what is the molecular weight of this gas?

Answers

Answer:

The molecular weight is [tex]Z = 111.2 \ g/mol[/tex]

Explanation:

From the question we are told that

   The mass of the sample is  [tex]m = 0.98 \ g[/tex]

    The temperature is  [tex]T = 348 K[/tex]

    The volume which the gas occupied is  [tex]V = 265 \ ml = 265 *10^{-3} L[/tex]

     The pressure is  [tex]P = 0.95 \ atm[/tex]

Generally from the ideal gas equation we have that

       [tex]PV = n RT[/tex]

Here n is the number of moles of the gas while the R is the gas constant with value  [tex]R = 0.0821 \ atm \cdot L \cdot mol^{-1} \cdot K^{-1}[/tex]

        [tex]n = \frac{PV}{ RT}[/tex]

=>      [tex]n = \frac{ 0.95 * 265 *10^{-3} }{ 0.0821 * 348}[/tex]

=>      [tex]n = 0.00881 \ mol[/tex]

Generally the molecular weight is mathematically represented as

          [tex]Z = \frac{m}{n}[/tex]

=>      [tex]Z = \frac{0.98 }{0.00881}[/tex]

=>      [tex]Z = 111.2 \ g/mol[/tex]

b. 37.
c. 6.
d. 8.

Answers

Answer:

c. 6.

Explanation:

Looking at the description given in the question, the elements involved must belong to the p- block of the periodic table and must be in period 5. They also must possess valence electrons in the 5p- orbital.

Now if we look at the p- block of period 5, the following elements satisfy these  requirements; Sr, In, Sn, Sb, Te and I.

Hence there are six of such elements.

The chemical elements that have atoms, in their ground-state, with valence electrons whose quantum numbers are n = 5 and l = 1 are: C. 6.

What is a valence electron?

A valence electron can be defined as the number of electrons that is present in the outermost shell of an atom.

In Chemistry, valence electrons are primarily used to determine whether an atom or group of chemical elements that are found on the periodic table can bond with others.

Based on electronic configuration, quantum numbers of n = 5 and l = 1 simply represents a 6p orbital and there a total of six (6) chemical elements with this orbital, and these include;

A motorist discovers that her auto tire measures 29.2 psi rather than the recommended 35 psi. If the tire’s volume is assumed constant at 11.6 L and the temperature is 45F at the filling station, how many moles of air will the motorist need to add to bring the tire to 35 psi? (assume 1.00 atm = 14.7 psi)

Answers

Answer:

  0.20 moles

Explanation:

The pressure is proportional to the quantity of gas at a given temperature and volume. So, the quantity needs to be increased by a factor of ...

  (35 psi)/(29.2 psi) = 175/146 ≈ 1.19863

The fractional increase required is ...

  1.19863 -1 = 0.19863

__

The quantity of air currently in the tire is ...

  1 mol·519.67°R/(atm·23.6442 L) × (29.2/14.7 atm) × (11.6 L) / (45+459.67)°R

  = 1.0035 mol

so we need to add ...

  (fraction to add) × (current quantity) = amount to add

  0.19863 × 1.0035 mol = 0.1993 mol = amount to add

About 0.20 moles of air must be added to the tire to bring the pressure up.

In the reaction of aluminum with iron III oxide, if you start with 54.2 grams of aluminum, how many grams of iron III oxide are needed for the reaction to occur? ​

Answers

Answer:

[tex]m_{Fe_2O_3}=160.41gFe_2O_3[/tex]

Explanation:

Hello!

In this case, since the reaction between aluminum and iron (III) oxide is:

[tex]2Al+Fe_2O_3\rightarrow Al_2O_3+2Fe[/tex]

In such way, since there is 2:1 mole ratio between aluminum (atomic mass = 26.98 g/mol) and iron (III) oxide (molar mass = 159.70 g/mol), we'll be able to compute the mass of the required reactant as shown below:

[tex]m_{Fe_2O_3}=54.2gAl*\frac{1molAl}{26.98gAl}* \frac{1molFe_2O_3}{2molAl}*\frac{159.70gFe_2O_3}{1molFe_2O_3}\\\\m_{Fe_2O_3}=160.41gFe_2O_3[/tex]
