What happens to a linguist when it releases enough energy

I think it is Concentration

Answer:

0.052L

Explanation:

Molarity of a substance, which refers to the molar concentration, is calculated as follows:

Molarity (M) = number of moles (mol) ÷ volume (L)

Mole = mass ÷ molar mass

Molar Mass of AgNO3 since Ag = 108, N = 14, O = 16

108 + 14 + 16(3)

= 108 + 14 + 48

= 170g/mol

Mole = 21.89 g ÷ 170g/mol

Mole = 0.129moles

Using Molarity (M) = number of moles (mol) ÷ volume (L)

Volume = number of moles ÷ molarity

V = 0.129 ÷ 2.50

V = 0.0516

To the correct significant figure i.e. 4s.f, the numerical value of volume = 0.052L

Answer:

[tex]m_{Hg}=829.4gHg[/tex]

Explanation:

Hello there!

In this case, considering the Avogadro's number, which helps us to realize that 1 mole of mercury atoms contains 6.022x10²³ atoms and at the same time 1 mole of mercury weights 200.59 g, we obtain:

[tex]m_{Hg}=2.49x10^{24}atoms*\frac{1mol}{6.022x10^{23}atoms} *\frac{200.59g}{1molHg}\\\\m_{Hg}=829.4gHg[/tex]

Answer:

2.0 × 10⁴ mg

Explanation:

Step 1: Given data

Mass (m): 0.020 kg

Step 2: Convert the mass from kilograms to grams

We will use the conversion factor 1 kg = 1,000 g.

0.020 kg × (1,000 g/1 kg) = 20 g

0.020 kg is equal to 20 g.

Step 3: Convert the mass from grams to milligrams

We will use the conversion factor 1 g = 1,000 mg.

20 g × (1,000 mg/1 g) = 2.0 × 10⁴ mg

20 g is equal to 2.0 × 10⁴ mg. Then, 0.020 kg is equal to 2.0 × 10⁴ mg.

Answer:

22 g

Explanation:

Step 1: Write the balanced equation

N₂(g) + 3 H₂(g) ⇒ 2 NH₃(g)

Step 2: Calculate the moles of NH₃ produced from 2.0 moles of H₂

The molar ratio of H₂ to NH₃ is 3:2.

2.0 mol H₂ × 2 mol NH₃/3 mol H₂ = 1.3 mol NH₃

Step 3: Calculate the mass corresponding to 1.3 moles of NH₃

The molar mass of NH₃ is 17.03 g/mol.

1.3 mol × 17.03 g/mol = 22 g

Answer:

Most manure consists of animal feces; other sources include compost and green manure. Manures contribute to the fertility of soil by adding organic matter and nutrients, such as nitrogen, that are utilised by bacteria, fungi and other organisms in the soil.

Explanation:

Hope it is helpful....

Answer:

Animal manure, such as chicken manure and cow dung, has been used for centuries as a fertilizer for farming. It can improve the soil structure (aggregation) so that the soil holds more nutrients and water, and therefore becomes more fertile. ... Manure is also commercially composted and bagged and sold as a soil amendment.

The time it takes for the radioactivity of a specific isotope to fall to half its original value

Explanation:

The half time is the time it takes for the radioactivity of a specific isotope to fall to half its original value.

In terms of radioactivity, it is the interval of time that should be needed for one half of the atomic nuclei with respect to the radioactive sample for decaying or here the time interval should be needed for the no of disintegrations per second of a radioactive

M = n/V(L)

0.844 mol (Both numbers have 3 significant figures so the result has 3 significant figures as well)

Explanation:

Step 1: Given and required data

Step 2: Calculate the moles (n) of ammonia (solute)

Molarity is equal to the moles of solute divided by the liters of solution.

M = n/V(L)

n = M × V(L)

n = 2.25 mol/L × 0.375 L = 0.844 mol (Both numbers have 3 significant figures so the result has 3 significant figures as well)

Answer:

Explanation:

4.125 g of copper oxide contains 3.294 g of Cu . Rest is oxygen

oxygen is 4.125 - 3.294 = .831 g

Ratio of oxygen and copper = .831 : 3.294

.831 / .831 : 3.294 / .831

= 1 : 3.96

1 : 4 ( Approx )

percentage of oxygen in copper oxide = 20 % approx

in the second experiment ,

1.476 g of copper oxide is formed from 1.179 g of Cu

oxygen in this copper oxide = 1.476 - 1.179 = .297 g

Ratio of oxygen and copper

.297 : 1.179

.297/.297 : 1.179/ .297

1 : 3.96

1 : 4 ( approx )

percentage of oxygen in copper oxide = 20 % approx

So it follows the law of definite proportions .

Answer: c plus sign

Answer:

18.01528 g/mol

Explanation:

Answer:

18.01528 g/mol

Explanation:

Answer:

(a). 46,666.7 g/mol; 78,571.4 g/mol

(b). 86950g/mol; 46,666.7 g/mol.

(c). 86950g/mol; 43,333.33 g/mol

Explanation:

So, we are given the molar masses for the three samples as: 10,000, 30,000 and 100,000 g mol−1.

Thus, the equal number of molecule in each sample = ( 10,000 + 30,000 + 100,000 ) / 3 = 46,666.7 g/mol.

The average molar mass = [ ( 10,000)^2 + (30,000)^2 + 100,000)^2] ÷ 10,000 + 30,000 + 100,000 = 78,571. 4 g/mol.

(b). The equal masses of each sample = 3/[ ( 1/ 10,000) + (1/30,000 ) + (1/100,000) ] = 20930.23 g/mol.

Average molar mass = ( 10,000 + 30,000 + 100,000 ) / 3 = 46,666.7 g/mol.

(c). Equal masses of the two samples = (0.145 × 10,000) + (0.855 × 100,000)/ 0.145 + 0.855 = 86950g/mol.

The weight average molar mass = 1.7 + 10,000 + 100,000/ 1.7 + 1 = 43,333.33 g/mol.

Answer:

[tex]\boxed {\boxed {\sf About \ 2.7 *10^{24}\ atoms\ N }}[/tex]

Explanation:

To convert from moles to atoms, Avogadro's Number: 6.022*10²³ must be used. This number tells us the amount of particles (atoms, molecules, etc) in 1 mole of a substance. In this case, the particles are atoms of nitrogen.

[tex]\frac {6.022 *10^{23} \ atoms \ N}{1 \ mol \ N}[/tex]

Multiply by the given number of moles: 4.5

[tex]4.5 \ mol \ N *\frac {6.022 *10^{23} \ atoms \ N}{1 \ mol \ N}[/tex]

The moles of nitrogen will cancel.

[tex]4.5 \ *\frac {6.022 *10^{23} \ atoms \ N}{1 }[/tex]

The denominator of 1 can be ignored.

[tex]4.5 \ *{6.022 *10^{23} \ atoms \ N}[/tex]

[tex]2.7099*10^{24} \ atoms \ N[/tex]

The original measurement of moles had 2 significant figures, so our answer must have the same. For the number we calculated, that is the tenth place. The 0 in the hundredth place tells us to leave the 7.

[tex]2.7 *10^{24}\ atoms\ N[/tex]

There are about 2.7*10²⁴ atoms of nitrogen in 4.5 moles.

We notice there is a 1:1 mole ratio between Al2O3 and Cr2O3; thus, the following stoichiometric setup is used to compute the theoretical yield first:

[tex]m_{Al_2O_3 }=23.3gCr_2O_3*\frac{1molCr_2O_3}{151.99gCr_2O_3} *\frac{1molAl_2O_3}{1molCr_2O_3} *\frac{101.96gAl_2O_3}{1molAl_2O_3} \\\\m_{Al_2O_3}=15.6gAl_2O_3[/tex]
