Answer:

When two or more atoms are chemically joined together, this is called a molecule. In some cases, such as hydrogen and oxygen, the molecule is made entirely of the same atom, such as hydrogen gas (a molecule) is made entirely of two hydrogen atoms. Here, converting molecules to atoms is as simple as dividing by two.

Atoms can join together - they form bonds together - to make MOLECULES. For example, two atoms of hydrogen hook together to form a molecule of hydrogen

vladimir2022 [97]

Answer:

Group 1 (or IA)

Explanation:

If element X is a halogen, then it belongs to the group 17 (or VIIA, under a different notation).

For each extra unit of atomic number, the group number increases by 1. That means that the X+1 element would belong to the group 18 (or VIIIA). <em>The X+2 element would thus belong in the group 1 </em>(or IA) one period higher (higher as in numeric value, not as in position in the periodic table).

Which element in period 4 has the highest electronegativity
vova2212 [387]

<span>Electronegativity is the property of an element that measures the ability of it to attract and form electron bonds. The trend in the periodic table in terms of electronegativity decreases from right to left and from top to bottom. In the case of period 4, the element with the highest electronegativity is bromine. </span>

For a particular reaction, Δ=−111.4 kJ and Δ=−25.0 J/K.
vichka [17]

Answer:

\Delta G =-103.95kJ

Explanation:

Hello there!

In this case, since the thermodynamic definition of the Gibbs free energy for a change process is:

\Delta G =\Delta H-T\Delta S

It is possible to plug in the given H, T and S with consistent units, to obtain the correct G as shown below:

\Delta G =-111.4kJ-(298K)(-25.0\frac{J}{K}*\frac{1kJ}{1000J} )\\\\\Delta G =-103.95kJ

Best regards!
