The molecular formula of glucose is C6H12O6. What is the empirical formula of glucose?(1) CHO (3) C6H12O6
(2) CH2O (4) C12H24O12

Answers

Answer 1
Answer: The answer is (2) CH2O. The empirical formula means the simplest positive integer ratio of the atoms in the compounds. You can get this form form the molecular formula, divided by 6 for each atom.

H2(g) + CO2(g) + 10 kcal H2O(g) + CO(g)In another experiment involving the above reaction at 1,000°C, the equilibrium concentrations were found to be:

H2(g) = 2.0 moles per liter
H2O(g) = 4.0 moles per liter
CO2(g) = 5.0 moles per liter
CO(g) = 4.0 moles per liter

What is the equilibrium constant, Keq, for this reaction?

Answers

The equilibrium contant for the reaction is 1.6. Solution: [H2]=2.0 mol/L [CO2]= 5.0 mol/L [H2O]= 4.0 mol/L [CO]= 4.0 mol/L K = [H2O][CO] / [H2][CO2] K = (4.0)(4.0) / (2.0)(5.0) K = 1.6 Ans [ =1.6 ]

How many electrons in an atom could have these sets of quantum numbers? n=2?

Answers

A maximum of 8 electrons can share the quantum number  n = 2.

Principal Quantum number has a symbol of "n". It tells you the energy level on which an electron resides. You need to determine exactly how many orbitals you have in this energy level before you can determine the number of electrons that can share the value of n.

The number of orbitals you get per energy level can be found using this formula:

no. of orbitals=n²

Each orbital can hold a maximum of two electrons, the formula would be:

no. of electrons=2n²

Using the given formulas:

no. of orbitals = n² = 2² = 4

no. of electrons =2 * 4 = 8 

This type of heat transfer is trapped in green houses. Conduction, Convection, Or Radiation and why is it conduction, convection, or radiation?

Answers

This transfer is radiation. This type of heat transfer is composed of electromagnetic waves from the Sun either through infrared or ultraviolet rays. Radioactive heat transfer is the only way to transfer heat from one place to another without a medium.

Answer:

infrared radiation

Explanation:

Light from the Sun passes through the glass roof to heat plants and the ground inside the greenhouse. These objects then emit infrared radiation, which is absorbed in the glass roof. Thermal energy is trapped in the greenhouse, keeping the building warm.
