Answer:

  2 Atm; 2.016 g

Explanation:

Changing the volume without changing the temperature or mass only changes the pressure. Volume and pressure are inversely proportional so halving the volume will double the pressure.

P = 1 Atm, T = 0 °C are "standard" temperature and pressure (STP). The volume of 1 mole of gas is 22.4 L under these conditions. That means the amount of hydrogen gas in the cylinder is 1 mole, so has a mass of 2.016 g.

After the volume reduction, the pressure is 2 Atm, and the mass remains 2.016 g.

There are 10 hydrogen atoms that bind and there are 2 pairs of free electrons in the non-binding O atom

<h3>Further explanation</h3>

Aldehydes are alkane-derived compounds containing carbonyl groups (-CO-) where one bond binds to an alkyl group while another binds to a hydrogen atom.

The general structure is R-CHO with the molecular formula :

\large{\boxed{\boxed{\bold{C_nH_{2n}O}}}

Naming is generally the same as the alkane by replacing the suffix with -al

Butanal or butyraldehyde is an aldehyde which has 4 C atoms

Inside the structure there are 3 atoms involved in bonding:

  • 1. Atom C with 4 valence electrons, requires 4 electrons to reach the octet
  • 2. Atom O with 6 valence electrons, requires 2 electrons to reach the octet
  • 3. Atom H with 1 valence electron, requires 1 electron to reach a duplet

In describing Lewis's structure the steps that can be taken are:

  •  1. Count the number of valence electrons from atoms in a molecule
  • 2. Give each bond a pair of electrons
  • 3. The remaining electrons are given to the atomic terminal so that an octet is reached
  • 4. The remaining electrons that still exist in the central atom
  • 5. If the central atom is not yet octet, free electrons are drawn to the central atom to form double bonds

In the Butanal structure (C₄H₈O) there is 1 double bond of the functional group (-CHO) between the C atom and the O atom

SIZIF [17.4K]
Answer: Potassium to fluorine, fluorine to nitrogen, bromine to hydrogen, carbon to hydrogen, lithium to chlorine, sodium to chlorine.
Explanation:
Ionic bond is greater when the electronegativity difference existing between the two atoms are large causing the bonding to be more polar.
