The empirical formula of a chemical substance is CH₂. The
molar mass of a molecule of the substance is 56.108 g/mol.
What is the molecular formula of the chemical substance?
Answer:
Explanation:
Remark
CH2 provides the basic structure of the hydrocarbon. It will be multiplied by some factor determined by the number of grams / mol. I will use rounded numbers because all periodic tables are slightly different.
Theoretical mass of CH2
1 C = 1 * 12 = 12
2 H= 2 * 1 = 2
Mass CH2 = 14
The multiplier for CH2
56.108 rounded = 56
Multiplier = molar mass (rounded)/Mass CH2
Multiplier = 56/14 = 4
Chemical
(CH2)_4 = C4H8
Answer: C4H8
In which stage do vertebrate embryos or offspring show the most similarities?

Substance x is known to exist at 1 atm in the solid, liquid, or vapor phase, depending on the temperature, is mathematically given as
Q=800J.mol^{-1}
What is a graph of the other properties of x?Generally, the equation for heat absorbed is mathematically given as
Q= Heat capacity of solid *T
In conclusion,
Q= (40)(293.15-273.15)
Q=800J.mol^{-1}
In conclusion, Because the enthalpy of fusion is 9 KJmol-1 and we are only providing 6 KJmol-1 of heat, the melting process will not be complete. the graph is attached.

a natrual distsater caused a population of 4,695 organisms to migrate to a new habitat. a few generations after the disaster it was observed that the new habitat did not sopport the survival of the species. the table shows the population of the species in two habitats
Answer:
49.54%
Explanation:
Given parameters:
Number of organisms in original habitat = 4695
Number of organism in new habitat = 2326
Solution:
To find the percentage of the organisms in the new habitat that has migrated to the new habitat, we use the expression below:
% of the population in the new habitat = x 100
% of the population in the new habitat = x 100 = 49.54%

how many grams of water would require 22000 joules of heat to raise its temperature from 34 C to 100 C. THe specific heat of water is 4.2 j/g C
The mass of water required to raise 22000 joules of heat from a temperature of 34°C to 100°C is 79.37g.
How to calculate mass?The mass of a substance can be calculated by using the following formula:
Q = m × c × ∆T
Where;
Q = quantity of heat absorbed or releasedm = mass of substancec = specific heat capacity∆T = change in temperature22000 = m × 4.2 × (100 - 34)
22000 = 277.2m
m = 22000/277.2
m = 79.37g
Therefore, the mass of water required to raise 22000 joules of heat from a temperature of 34°C to 100°C is 79.37g.

The molar enthalpy of combustion in kj/mol of magnesium is 620 kj/mol, Option D is the correct answer.
What is enthalpy of Combustion ?The energy released when a fuel is oxidized by an oxidizing agent is called enthalpy of Combustion.
It is given that
a 1.0 g sample of magnesium is burned to form MgO. in doing so, 25.5 kj of energy are released.
Molecular weight of Magnesium = 24.35g
24.35 g makes 1 mole of Mg
1g = 1/24.35
For 0.04 moles 25.5 kJ is released
for 1 mole 25.5 *1/.04
= 620 kj/mol
Therefore the molar enthalpy of combustion in kj/mol of magnesium is 620 kj/mol.
