Answer:

X+ ion cation is smaller than neutral atom because when one or more electrons are lose by an atom it usually result in lose of shell.

And when electron is removed positive/ negative charged ratio increas which causes more effective nuclear charge.

The more effective nuclear charge the less its size.

In a group of water molecules, where do hydrogen bonds form?

ollegr [7]

Answer:

Water molecules forming hydrogen bonds with one another. The partial negative charge on the O of one molecule can form a hydrogen bond with the partial positive charge on the hydrogens of other molecules. Water molecules are also attracted to other polar molecules and to ions.

The hybrid orbital set used by the central atom in h2co is ________. the hybrid orbital set used by the central atom in h2co is

Feliz [49]

The Lewis structure for H₂CO is shown in the attached picture. The central atom is the carbon. However, I'm not sure which bond you're referring to. There can be two answers. The two C-H bonds are sp³ hybridized because it is a single bond. The C=O bond is sp² hybridized because it is a double bond.

Equal volumes of H2 and O2 are placed in a balloon and then ignited. Assuming that the reaction goes to completion, which gas wi

nirvana33 [79]

The reaction is

2H₂(g) + O₂(g) ---> 2H₂O

Thus as per balanced equation two moles of hydrogen will react with one moles of oxygen.

There is a directly relation between moles and volume. [One mole of each gas occupies 22.4 L of volume at STP]

Thus we can say that two unit volume of hydrogen will react with one unit volume of oxygen

Now as we have started with equal units of volume of both oxygen and hydrogen, half of oxygen will be consumed against complete volume of hydrogen

so the gas which will remain in excess is oxygen

Answer: The statement, average kinetic energy of the gas particles is greater in container A because its particles move faster is correct.

Explanation:

Kinetic energy is the energy obtained due to the motion of an object or substance.

$K.E = \frac{3}{2}kT$

where,

T = temperature

This means that kinetic energy is directly proportional to temperature.

So, when heat is provided to container A then its molecules will start to move rapidly from one place to another which will cause more collisions between the atoms.

Hence, average kinetic energy will be more in container A.

Whereas container B is placed at room temperature which is low than that in container A. So, molecules in container B will move at almost same speed and therefore, specific collisions will be there. So, average kinetic energy in container B will be less than that in container A.

Thus, we can conclude that the statement, average kinetic energy of the gas particles is greater in container A because its particles move faster is correct.
