Answer:

This question appears incomplete

Explanation:

The periodic table is divided into 4 blocks; s-block, p-block, d-block and the f-block.

Elements found in the s-block are metals; alkali metals and alkali earth metals. Elements found in the p-block include metals and non-metals while those found in the d-block are metals (transition metals). The F-block elements are the radioactive elements.

Oxygen (O) and selenium (Se) are non-metals found in group 16 of the periodic table which is found in the p-block of the periodic table. The p-block is located on the right side of the periodic table. Generally, non-metals are poor conductors of electricity.

Structural isomers are molecules that have the same chemical formula but different structures and chemical properties. For examp

kicyunya [14]

Answer:

Neopentane (C(CH3)4) have a lower a lower boiling point than n-pentane (CH3CH2CH2CH2CH3) because of it branched chain.

Explanation:

Structural isomers are compounds that have the same molecular or chemical formula but have different arrangement of atoms in space. The connectivity of the atoms differs for this compounds but they possess the same molecular formula. An example of structural isomers are butane and methyl propane. Usually, as the number of carbon increases for alkane the number of isomers also increases.

Since Isomers are different compound they are bound to have different characteristic both in melting and boiling points. Generally, straight chained isomers have higher boiling points than branched chain isomers.

n-pentane (CH3CH2CH2CH2CH3) is a straight chained isomer while neopentane (C(CH3)4) is a branched chain isomer. Neopentane (C(CH3)4) have a lower a lower boiling point than n-pentane (CH3CH2CH2CH2CH3) because of it branched chain.

What property of water allows water to work as a universal solvent?

fgiga [73]

Answer:

The water is universal solvent because it is a polar molecule.This have hydrogen bonding in which hydrogen molecule have positive charge and oxygen molecule have negative charge because electro negativity of oxygen molecule is higher than hydrogen molecule that is why it pull the hydrogen molecule and formed a polar molecule.That is why is also known as universal solvent.

Which statement describes why sodium reacts more vigorously than magnesium to hydrochloric acid? Refer to the periodic table. Ci

lions [1.4K]

Sodium has a lower ionization energy than magnesium describes why sodium reacts vigorously than magnesium chloride.

<h3>Why is sodium more reactive than magnesium?</h3>

Sodium is more reactive than magnesium because it has the ability to easily lose electron, hence have lower ionization energy.
Sodium belong to group one on the periodic table and they are called akali metal while magnesium belong to group two on the periodic table and they are called alkali Earth metal.

Sodium and magnesium belong to the in the 3rd period. Iin the outermost energy level sodium has one electron but magnesium has 2 electrons. Therefore, there is more attraction abetween the nucleus and electrons in magnesium than that of sodium.

Therefore, sodium is more reactive than magnesium chloride because of lower ionization energy.
