What is the total number of pairs of electrons shared between the carbon atom and the oxygen atom in a molecule of methanal?

1 answer:

8 0

Answer is: between the carbon atom and the oxygen atom in a molecule of methanal there are two (2) pairs of electrons.

Methanal or formaldehyde (H₂C=O) is the simplest of the aldehydes.
In methanal, bond between carbon and oxygen is double covalent bond (one sigma and one pi bond), which means there are four shared electrons or two pair of electrons.

D. I or Iodine

This is because they are both in the same periodic family (the halogens) and thus the number of valence electrons are the same

Propane(C3H8) combusts with oxygen gas. If you start with 15 grams of Propane, how many grams of carbon dioxide will be produced

skelet666 [1.2K]

mC₃H₈: 44 g/mol
mCO₂: 44 g/mol
---------------------

C₃H₈ + 5O₂ ----> 3CO₂ + 4H₂O
44g (44·3)g

44g C₃H₈ ------ 132g CO₂
15g C₃H₈ ------ X
X = (15×132)/44
X = 45g CO₂

Which law relates to the ideal gas law?

professor190 [17]

Answer: The law that related the ideal gas law is $\frac{V_1}{n_1}=\frac{V_2}{n_2}$

Explanation:

There are 4 laws of gases:

Boyle's Law: This law states that pressure is inversely proportional to the volume of the gas at constant temperature.

Mathematically,

$P_1V_1=P_2V_2$

Charles' Law: This law states that volume of the gas is directly proportional to the temperature of the gas at constant pressure.

Mathematically,

$\frac{V_1}{T_1}=\frac{V_2}{T_2}$

Gay-Lussac Law: This law states that pressure of the gas is directly proportional to the temperature of the gas at constant pressure.

Mathematically,

$\frac{P_1}{T_1}=\frac{P_2}{T_2}$

Avogadro's Law: This law states that volume is directly proportional to number of moles at constant temperature and pressure.

Mathematically,

$\frac{V_1}{n_1}=\frac{V_2}{n_2}$

Hence, the law that related the ideal gas law is $\frac{V_1}{n_1}=\frac{V_2}{n_2}$
