Answer:

When two nuclei form one atom, fusion reactions occur. Two hydrogen atoms combine to produce helium with the sun's reaction. It looks very simplified as follows: H+ H + D + D + H + D. This is referred to as a mass deficit and that mass differential becomes energy.

A gas is collected at 25.0 °C and 755.0 mm Hg. When the temperature is
Mashcka [7]

Answer:

691.7 mmHg is the resulting pressure

Explanation:

Tha Gay-Lussac's law states that the pressure of a gas is directly proportional to its absolute temperature under constant volume. The equation is:

P1T2 = P2T1

<em>Where P is pressure and T asbolute temperature of 1, initial state and 2, final state of the gas.</em>

<em />

Computing the values of the problem:

T1 = 273 + 25 = 298K

P1 = 755.0mmHg

T2 = 273 + 0 = 273K

P2 = ?

755.0mmHg*273K = P2*298K

<h3>691.7 mmHg is the resulting pressure</h3>

The electron configuration of an element is 1s22s22p4.
MissTica

The likely thing which happens when two atoms of this element move toward each other is covalent bonding.

<h3>What is Covalent bonding?</h3>

This involves the atoms of element sharing electrons in order to achieve a stable octet configuration.

The element is oxygen which has an atomic number of 8 and needs two electrons to complete its outermost shell which results in the formation of two covalent bonds.
