Based on the equation below, how many moles of aluminum sulfate (Al2(SO4)3) will be produced from the reaction of 5.8 moles of aluminum hydroxide (Al(OH)3) and excess sulfuric acid (H2SO4)? 2Al(OH)3 + 3H2SO4 → Al2(SO4)3 + 6H2O
Answer:
2.9 moles of aluminum sulfate will be produced from the reaction of 5.8 moles of aluminum hydroxide and excess sulfuric acid.
Explanation:
The balanced reaction is:
2 Al(OH)₃ + 3 H₂SO₄ → Al₂(SO₄)₃ + 6 H₂O
By reaction stoichiometry (that is, the relationship between the amount of reagents and products in a chemical reaction), the following amounts of each compound participate in the reaction:
Al(OH)₃: 2 moles H₂SO₄: 3 moles Al₂(SO₄)₃: 1 mole H₂O: 6 molesThen you can apply the following rule of three: if by reaction stoichiometry 2 moles of Al(OH)₃ produce 1 mole of Al₂(SO₄)₃, then 5.8 moles of Al(OH)₃ how many moles of Al₂(SO₄)₃ will they produce?
[tex]moles of Al_{2} (SO_{4} )_{3} =\frac{5.8moles of Al(OH)_{3} *1 mole of Al_{2} (SO_{4} )_{3}}{2moles of Al(OH)_{3}}[/tex]
moles of Al₂(SO₄)₃= 2.9
2.9 moles of aluminum sulfate will be produced from the reaction of 5.8 moles of aluminum hydroxide and excess sulfuric acid.

49. Identify the noble gas that has atoms in the ground state with the same electron configuration as the nitrogen in a molecule of isocyanic acid
Answer:
Neon (Ne)
Explanation:
Nitrogen in it's neutral state has valency of 5 and it's electronic configuration is given as;
1s2 2s2 2p3
However in isocyanic acid, it forms a covalent bond with hydrogen and carbon. Due to this bond, it is able to achieve stable octet configuration. The configuration is given as;
1s2 2s2 2p6
This is the same electronic configuration as Neon
What is the mass in grams of a 10.2cm3 block of copper
Answer:
91.4
Explanation:
Givens
d = 8.96
v = 10.2 cm^3
m =?
Formula
d = m / V
Solution
8.96 = m / 10.2 Multiply both sides by 10.2
8.96 * 10.2 = m
m = 91.392 grams
m = 91.4 grams rounded.

State, in terms of the strength of intermolecular forces, why 12 has a higher boiling point than F2
Answer:
See explanation
Explanation:
The greater the relative atomic mass of an atom the more polarizable the atom is.
Also, the magnitude of dispersion forces depends on the molecular mass of the compound.
We must remember that both I2 and F2 are nonpolar molecules that are purely held together by dispersion forces.
Hence, I2, having the greater molecular mass and surface area experiences a greater magnitude of dispersion forces and consequently has a higher boiling point than F2.
37.9 grams of an unknown substance undergoes a temperature increase of
25.0*C after absorbing 969 J. What is the specific heat of the substance?
Answer:
1.023 J / g °C
Explanation:
m = 37.9 grams
ΔT = 25.0*C
H = 969 J
c = ?
The equation relating these equation is;
H = mcΔT
making c subject of formulae;
c = H / mΔT
c = 969 J / (37.9 g * 25.0*C)
Upon solving;
c = 1.023 J / g °C

How many atoms of nitrogen appear to be on the reactant side?
Dissociation and THEN hydration afterwards is the process of: * 1 point water pulling a compound apart and then surrounding the broken pieces/ions (this is what dissolving is) breaking down the food into simpler nutrients that can be used by the cells a mental process where a person disconnects from their thoughts, feelings, memories or sense of identity
Answer:
water pulling a compound apart and then surrounding the broken pieces/ions (this is what dissolving is)
Explanation:
As we know, water is a polar solvent. What this means is that water can effectively interact with ions in an ionic substance owing to its large dipole moment.
Now, when an ionic substance is dissolved in water, the positive end in water pulls hard on the negative ion of the ionic substance while the negative end in water pulls hard on the positive ion of the ionic substance.
The ionic substance is eventually pulled apart and surrounded by water molecules. This is how an ionic substance is dissolved in water.

Answer:
Energy of the Reactant: increases
Energy of the product: not at all
Rate of reaction: increases
Enthalpy: not at all
Activation energy: decreases
Explanation:
Catalyst is a substance that increases the rate of reaction than normal to form a product.
Catalyst affect differently to different factors of reaction. A catalyst is meant to increase rate of reaction by lowering the activation energy, so that collision between reactant increase and that passes the energy barrier to form the product faster.
Catalyst has no effect on Enthalpy as change in enthalpy only depends on the chemical compositions of the reactants and products.
Catalyst also increases energy of reactant so that they can collide faster than before and do not affect the energy of product at all.
Hence, the correct answer is:
Energy of the Reactant: increases
Energy of the product: not at all
Rate of reaction: increases
Enthalpy: not at all
Activation energy: decreases
How many atoms are there in 48 grams of carbon?
Answer:
20
Explanation:
How many liters of solution would it take to make a 0.250 M solution when you have 3.52 moles of solute?
Answer:
The volume of solution in liters required to make a 0.250 M solution from 3.52 moles of solute is 14.08 liters of solution
Explanation:
The question relates to the definition of the concentration of a solution which is the number of moles per liter (1 liter = 1 dm³) of solution
Therefore we have;
The concentration of the intended solution = 0.250 M
Therefore, the number of moles per liter of the required resolution = 0.250 moles
Therefore, the concentration of the required solution = 0.250 moles/liter
The volume in liters of the required solution that will have 3.52 moles of the solute is given as follows;
The required volume of solution = The number of moles of the solute/(The concentration of the solution)
∴ The required volume of solution = 3.52 moles/(0.250 moles/liter) = 14.08 liters
The required volume of solution to make a 0.250 M solution from 3.52 moles of solute = 14.08 liters.
Therefore the number of liters required to make a 0.250 M solution from 3.52 moles of solute = 14.08 liters.
The diagrams below represent some respiratory structures in three organisms. The labeled structures in these organisms all have a similar function. What is the main function of the labeled structure(s) in each organism?
A)Circulation of blood
B)Digestion of food
C)Production of food
D)Exchange of gases
Answer:
D
Explanation:
Lungs, Moist skin , Gills is in the exchange of gases system
The correct answer is D.
The structure of human lungs is first demonstrated in an organism.
Lungs are the respiratory organs. They are made up of alveoli.Main Function :The main function of lungs is the gaseous exchange. This gaseous exchange occurs in the alveoli. Oxygen from atmosphere comes into the lungs through nostrils, nasal cavities, pharynx, larynx, trachea, bronchi and finally reaches the lungs. Then gaseous exchange occurs between blood and alveoli. Oxygen enters into the blood and carbon dioxide leaves the blood.The structure of Earthworms Moist skin is second demonstrated in an organism.
The earthworm has no special respiratory organs like lungs or gills. Respiration takes place through the body wall. The outer surface of the skin is richly supplied with blood capillaries which aid in the diffusion of gases. Oxygen diffuses through the skin into the blood while carbon dioxide from the blood diffuses out. The skin is kept moist by mucous and coelomic fluid and facilitates exchange of gases.The structure of Fish Gills is third demonstrated in an organism.
The gill filaments in fish have functions like lungs in people: it's the organ responsible for absorbing oxygen and expelling carbon dioxide. The gills also regulate levels of mineral ions and the pH of the blood, as well as being the primary site of nitrogenous waste excretion, in the form of ammonia.Learn more about Respiratory System here:
