Answer:

a) number measurement

Explanation:

relating to, measuring, or measured by the quantity of something rather than its quality.

Answer:

number and measurement

Explanation:

Quantitative is an adjective that simply means something that can be measured. For example, we can count the number of sheep on a farm or measure the gallons of milk produced by a cow.

Answer: A

Explanation:

Answer:

B

Explanation:

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.

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.

Answer:

6.50 mol

Explanation:

The question is incomplete but I looked it up on the web.

How many moles of water are produced when 3.25 moles of CO₂ are formed during the combustion of methyl alcohol (CH₃OH)?

Step 1: Write the balanced equation

2 CH₃OH +  3 O₂ → 2 CO₂ + 4 H₂O

Step 2: Establish the appropriate molar ratio

According to the balanced equation, the molar ratio of CO₂ to H₂O is 2:4.

Step 3: Calculate the moles of water formed with 3.25 moles of carbon dioxide

We will use the established molar ratio.

3.25 mol CO₂ × (4 mol H₂O/ 2 mol CO₂) = 6.50 mol H₂O

Chemists generally use the mole as the unit for the number of atoms or molecules of a material. One mole (abbreviated mol) is equal to 6.022×1023 molecular entities (Avogadro's number), and each element has a different molar mass depending on the weight of 6.022×1023 of its atoms (1 mole).\

Let's consider the chemical formula of ammonium carbonate: (NH₄)₂CO₃.

The subscripts inform us of the number of moles of atoms in 1 mole of molecules.

Nitrogen has 2 subscripts: "1" (which is not written) and "2" (outside the parenthesis). The global subscript for nitrogen is obtained by multiplying both subscripts.

[tex]N: 1 \times 2 = 2[/tex]

Hydrogen has 2 subscripts: "4" and "2" (outside the parenthesis). The global subscript for nitrogen is obtained by multiplying both subscripts.

Answer:

the average speed of [tex]V_{av} CO_2[/tex] is 5.24 ×  104 cm/s

Explanation:

The computation of the average speed of a [tex]CO_2[/tex] is as follows:

[tex]\sqrt{average} = \sqrt{\frac{8 RT}{\pi M} }[/tex]

where,

M = Molar mass

[tex]V_{av} = \frac{\sqrt{1}}{M}[/tex]

Given that

[tex]V_{av} \ of\ oxygen= 6.14 \times 10^4 cm/s[/tex]

The molar mass of oxygen i.e. (MO_2) = 31.9988 g/mol

And, the molar mass of CO_2 is  44.0098 g/mol

Now

[tex]\frac{V_{av} CO_2}{V_{av} O_2} = \frac{\sqrt{M_{O2} }}{M_{CO2}}[/tex]

Now place these values to the above formula

[tex]\frac{V_{av}CO_2}{6.14\times 104 cm/s} = \frac{\sqrt{31.9988} }{44.0098}[/tex]

So,

V_av CO_2 is 5.24 ×  104 cm/s

hence, the average speed of [tex]V_{av} CO_2[/tex] is 5.24 ×  104 cm/s

Answer:

the change in internal energy of the gases is  -3.0924 KJ

Explanation:

The computation of the change in internal energy of the gases is as follows;

Given that

Q = -3.1 KJ

= -3100 J

It is negative as the heat is lost from the mixture

And,

W = + 7.6 J

It is positive as the work is done in the mixture

Now we use the following equation

Delat E = Q + W

= -3100 J + 7.6 J

= -3092.4 J

= -3.0924 KJ

Hence, the change in internal energy of the gases is  -3.0924 KJ

A 7.59 mol Ne

Explanation:

The number of moles of Ne in a sample of 4.57 x 10²⁴ atoms of neon (Ne) are 7.59 mol of Ne. Hence Option (A) is the correct option. It can be solved with the help of Mole concept.

The mole, symbol mol, is the SI base unit of amount of substance.

The quantity amount of substance is a measure of how many elementary entities of a given substance are in an object or sample.

n = given number / Avogadro's number

  = 4.57 x 10²⁴ / 6.022 x 10²³

  = 7.59 mol of Ne

Therefore, The number of moles of Ne in a sample of 4.57 x 10²⁴ atoms of neon (Ne) are 7.59 mol of Ne. Hence Option (A) is the correct option. It can be solved with the help of Mole concept.

Answer:

B) Na3BO3.

Explanation:

Hello!

In this case, since percent compositions are used to identify the empirical formula of an unknown compound, we can assume we have 54.0 g of sodium, 8.50 g of boron and 37.5 g of oxygen, and we compute the moles of each one:

[tex]n_{Na}=54.0g*\frac{1mol}{23g} =2.35mol\\\\n_B=8.50g*\frac{1mol}{11g}=0.773mol\\\\n_O=37.5g*\frac{1mol}{16g}=2.34mol[/tex]

Now, we divide by the moles of boron as those are the fewest:

[tex]Na:\frac{2.35}{0.773}=3\\\\B:\frac{0.773}{0.773}=1\\\\O=\frac{2.34}{0.773}=3[/tex]

Thus, the empirical formula is B) Na3BO3.
