How many grams of NH3 can be dissolved in 50 grams of water at 50oC?
Answers
15 grams of NH3 can be dissolved
Further explanationGiven
50 grams of water at 50°C
Required
mass of NH3
Solution
Solubility is the maximum amount of a substance that can dissolve in some solvents. Factors that affect solubility
1. Temperature: 2. Surface area: 3. Solvent type: 4. Stirring process:We can use solubility chart (attached) to determine the solubility of NH3 at 50°C
From the graph, we can see that the solubility of NH3 in 100 g of water at 50 C is 30 g
So that the solubility in 50 grams of water is:
= 50/100 x 30
= 15 grams

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
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 grams of PH3 will be produced if 6.0 l of H2 are used?
Answers
Mass of PH3= 6.086 g
Further explanationGiven
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

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.

Single Replacement
Further explanationGiven
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)
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
