How many moles of H2S are produced?

Answers

Answer:

You can view more details on each measurement unit: molecular weight of H2S or grams This compound is also known as Hydrogen Sulfide. The SI base unit for amount of substance is the mole. 1 mole is equal to 1 moles H2S, or 34.08088 grams. Note that rounding errors may occur, so always check the results.

The number of grams that one "mole" of a substance weights is the definition of molar mass. So, the molar mass of H₂S is "34.08088"gams.

Molar mass:

In the definition of molar mass is the total atomic weights of the atoms that make up a molecule.Detailed information about each measurement unit can be found here: H₂S molecular weight in grams Hydrogen Sulfide is another name for this substance. A mole is the SI base unit for substance quantity. One mole of H₂S, or 34.08088 grams, is equal to one mole of H₂S.

how many grams of PH3 will be produced if 6.0 l of H2 are used?

Answers

Mass of PH3= 6.086 g

Further explanation

Given

6.0 L of H2

Required

mass of PH3

Solution

Reaction

P4 + 6H2 → 4PH3

Assumed at STP ( 1 mol gas=22.4 L)

Mol of H2 for 6 L :

= 6 : 22.4 L

= 0.268

From the equation, mol PH3 :

= 4/6 x moles H2

= 4/6 x 0.268

= 0.179

Mass PH3 :

= 0.179 x 33,99758 g/mol

= 6.086 g

O Combustion
O Decomposition
O Double Replacement
O Neutralization
O Single Replacement
O Synthesis

Answers

Single Replacement

Further explanation

Given

Reaction

Mg(s) + 2 HCl(aq) → MgCl2 (aq) + H2 (g)

Required

Type of reaction

Solution

A single replacement reaction is a chemical reaction in which one element replaces the other elements of a compound to produce new elements and compounds

General formula :

A + BC ⇒ AC + B

Not all of these reactions can occur. We can use the activity series(the Volta series)

The more left the position of a metal in the series, the more reactive metal (easy to release electrons, the stronger the reductor)

What happens to the average kinetic energy at a constant temperature? *

1.it increases
2.it decreases
3.it stays the same
4.it disappears

Answers

The answer is A, it increases.


As the temperature increases, the average kinetic energy increases as does the velocity of the gas particles hitting the walls of the container. The force exerted by the particles per unit of area on the container is the pressure, so as the temperature increases the pressure must also increase.

How many atoms are found in a 15.5 g sample of bismuth?

Answers

Answer:

4.47 x 10²² atoms

Explanation:

Given parameters:

Mass of Bismuth  = 15.5g

Unknown:

Number of atoms  = ?

Solution:

To find the number atoms, first solve for the number of moles in this element first.

  Number of moles  = [tex]\frac{mass}{molar mass}[/tex]    

  Number of moles  = [tex]\frac{15.5}{209}[/tex]    = 0.074mole

So:

        1 mole of a substance contains 6.02 x 10²³ atoms

     0.074 mole of Bismuth will contain 0.074 x 6.02 x 10²³ atoms

                                                          = 4.47 x 10²² atoms
