Answer:

The answer to your question is B

Answer:

A) 3.115 mol

B) 11.60 g h2

Explanation:

From the equation

2 mol Li gives 1 mol H2

Then 6.23 gives??

6.23 /2 = 3.116 mol H2

B) moles of Li =mass! molar mass

= 80.57/ 6.941 = 11.6 mol Li

Then moles of H2 = 11.6 /2 = 5.8 mol H2

Mass of H2 = mol * molar mass

5.8*2 =11.6 g h2

The moles of hydrogen formed with 6.23 moles of Li have been 3.115 moles. The mass of hydrogen formed with 80.57 grams of Li has been 11.60 grams.

From the balanced chemical equation,

2 moles Li = 1 mole Hydrogen

(a) The given moles of Li = 6.23 mol .

6.23 mol of Li = [tex]\rm \dfrac{1}{2}\;\times\;6.23[/tex] moles of hydrogen

6.23 mol Li = 3.115 moles of hydrogen.

The moles of hydrogen formed with 6.23 moles of Li have been 3.115 moles.

(b) The moles can be expressed as:

Moles = [tex]\rm \dfrac{weight}{molecular\;weight}[/tex]

Moles of Li in 80.57 grams:

Moles of Li = [tex]\rm \dfrac{80.57}{6.941}[/tex]

Moles of Li = 11.60 moles

The amount of Hydrogen formed:

2 moles Li = 1 mole Hydrogen

11.60 mol of Li = [tex]\rm \dfrac{1}{2}\;\times\;11.60[/tex] moles of hydrogen

11.60 mol Li = 5.803 moles of hydrogen.

Mass =  moles × molecular mass

Mass of 5.803 moles of Hydrogen = 5.803 × 2

Mass of hydrogen = 11.60 grams

The mass of hydrogen formed with 80.57 grams of Li has been 11.60 grams.

Answer:

1.52 M

Explanation:

Molarity of a solution is calculated as follows:

Molarity = number of moles (n) ÷ volume (V)

Based on the information given in this question,

Volume of soda (V) = 9.13 L

number of moles = 13.83 mol

Molarity = 13.83 ÷ 9.13

Molarity = 1.52 M

Answer:

C Region

Explanation:

C Region contains all the liquids as 0 °C is the freezing point of water (Crystals of water are formed leaving it no more in the liquid state) and 100 °C is the boiling point (The water boils leaving it no more in the liquid state).

Hence, All liquids are contained in the C region.

Answer:

Im pretty sure you use mass

Explanation:

Answer:

Los químicos eligen definir la AMU como 1/16 de la masa promedio de un átomo de oxígeno que se encuentra en la naturaleza; es decir, el promedio de las masas de los isótopos conocidos, ponderado por su abundancia natural. Los físicos, por otro lado, lo definieron como 1/16 de la masa de un átomo del isótopo oxígeno-16 (16O).

Explanation:

Sodium Chloride or NaCl is made up of two elements, sodium (or Na) and chlorine (or Cl). A molecule of sodium chloride, NaCl, consists of one atom each of sodium and chlorine. Hence, each molecule of NaCl has 2 atoms total.

Answer:

0.716

Explanation:

First, write the balanced equation:

3 H2CO3 + 2 Fe(OH)3 ----> Fe2(CO3)3 + 6 H2O

Second, go from the molarity of H2CO3 to liters of Fe(OH)3

(Pull mole ratio from balanced equation)

1.22/1L  x  0.0880/1  x  3molH2CO3/2molFe(OH)3 x 1/0.225L

Use calculator, and you end up with 0.7157333

Answer:

OB. Energy transfer would occur between the copper bars and the surroundings.

Explanation:

We define an isolated system as a system in which there is neither exchange of material nor energy while an open system is one in which materials and energy can be exchanged with the environment.

Given an open system consisting of two copper bars at different temperatures, energy will not only be exchanged between the copper bars but also between the copper bars and the environment.

Answer:

I think the w/w% of this question is 10.

The w/w% of a solution that contains 10 grams of solute and 100 grams of solvent is 9.09%

Mass percentage is another name of w/w % or weight /weight % .

To determine the weight/weight % of a solution :

we divide the mass of solute by mass of the solution (solute and solvent together) and multiply by 100 to obtain per cent.

[tex]\dfrac{w}{w} \; \%\; =\;\rm\dfrac{mass \;of\; solute}{mass\; of \; solute\;+\;mass\;of\;solvent} \times 100[/tex]

It is given that , mass of solute = 10 grams and mass of solvent = 100 grams

So,

[tex]\dfrac{w}{w} \; \%\; =\;\rm\dfrac{10}{10+100} \times 100[/tex]

[tex]\dfrac{w}{w} \; \%\; =\;\rm\dfrac{10}{110} \times 100\\\\\dfrac{w}{w} \; \%\; =\;\rm\dfrac{100}{11}\\\\\dfrac{w}{w} \; \%\; =\; 9.09 \;\%[/tex]

The w/w% of a solution that contains 10 grams of solute and 100 grams of solvent is 9.09% .

Answer:

The titration process has quite a few real-world uses, including key roles in the food industry and medical community. The titration process is essentially an analytical technique, as it is used to determine a chemical or physical property of a chemical substance, element, or mixture (such as food). Specifically in the food industry, it is used to allow food manufactuers to determine the quantity of a reactant in a sample. To provide an example, it can be used to find the specific amount of stuff that is usually labeled on the nutrition label, such as sugar, salt, protein, calcium, vitamin C, etc. As for the medical world, pharamcists typically use this process to get the proper mix when compounding medicines. It is used to get the necessary proportions in intravenous drips.

Answer:

1.8 L

Explanation:

According to Avogadro;

1 mole of CH4 contains 6.02 * 10^23 molecules of CH4

x moles of CH4 contains 2.50 x 10^22 molecules of CH4

x = 1 * 2.50 x 10^22 molecules/ 6.02 * 10^23 molecules

x = 0.04 moles of CH4

2 moles of H2 yields 1 mole of CH4 gas

x moles of H2 gas yields  0.04 moles of CH4

x = 2 moles * 0.04 moles / 1mole = 0.08 moles of H2

x = 0.08 moles of H2

Since 1 mole of H2 occupies 22.4 L

0.08 moles of H2 occupies 0.08 moles * 22.4 L/ 1 mole

= 1.8 L

Explanation:

Trust

Answer:

15.5 moles

Explanation:

Applying,

PV = nRT.................. Equation 1

Where P = pressure, V = Volume, n = number of mole, R = molar gas constant, T = Temperature.

Make n the subject of the equation

n = PV/RT............... Equation 2

From the question,

Given: P = 0.899 atm, V = 425 L, T = 24 °C = (273+24) K = 297 K.

Constant: R = 0.083 L.atm/K.mol

Substitute these values into equation 2

n = (0.899×425)/(297×0.083)

n = 15.5 moles

Answer:

The electric force between them decreases

Explanation:

The force between two charged particle is given by :

[tex]F=\dfrac{kq_1q_2}{r^2}[/tex]

Where

r is the distance between charges

If the distance between the charges is increased, the electric force gets decreased as there is an inverse relation between force and distance.

Hence, the correct option is (c) "The electric force between them decreases"
