Based on observation of polar and non-polar molecules, polar molecules would attract each other more strongly.

<h3>What are polar and non-polar molecules?</h3>

Polar molecules are those molecules that can ionize or dissociate into their respective positive and negative ions when in an aqueous solution.

Nonpolar molecules, on the other hand, are not ionic i.e. not dissociating into ions when dissolved in water.

Polar molecules like water (H2O) contains an uneven distribution of cations (+) and anions (-), hence, would be more attracted to one another than nonpolar molecules that have an even distribution of ions.

Solid calcium carbonate breaks down into carbon dioxide gas, oxygen gas, and solid calcium, write an equation for described reac
Savatey [412]

Answer:

CaCO₃ ------> CaO + CO₂

<em>Note: The breakdown products of solid calcium carbonate is not carbon dioxide gas, oxygen gas, and solid calcium. Rather, it is calcium oxide and carbon dioxide as shown in the reaction equation above.</em>

Explanation:

Calcium carbonate is a mineral which occurs in nature in rocks as calcite and limestone. It is also the main component of eggshells, snail shells, seashells and pearls. It has the molecular formula CaCO₃.

Calcium carbonate or limestone decomposes into calcium oxide and carbon dioxide when heated and the reaction is used to make quicklime and carbon dioxide gas. The equation of the reaction is given below:

CaCO₃ ------> CaO + CO₂

Calcium oxide, one of the products of The decomposition reaction is known as lime and is an important mineral used for many purposes such as reducing the acidity of soils, in the production of limelight, as well as serving as the main ingredient in cement.

The main use of calcium carbonate is in the construction industry as an ingredient of cement. Calcium carbonate is also an important mineral required by sea organisms for making their shells.

1 mol of titanium,<br> Ti, is 47.88 g is that true?
Ganezh [65]

Answer: True.

Explanation:

Molar mass is the mass of a given substance divided by the amount of that substance, measured in g/mol. For example, the atomic mass of titanium is 47.88 amu or 47.88 g/mol. In 47.88 grams of titanium, there is one mole, or 6.022 x 1023 titanium atoms.

The characteristic molar mass of an element is simply the atomic mass in g/mol. However, molar mass can also be calculated by multiplying the atomic mass in amu by the molar mass constant (1 g/mol). To calculate the molar mass of a compound with multiple atoms, sum all the atomic mass of the constituent atoms.

For example, the molar mass of NaCl can be calculated for finding the atomic mass of sodium (22.99 g/mol) and the atomic mass of chlorine (35.45 g/mol) and combining them. The molar mass of NaCl is 58.44 g/mol.

Substances like liquid mercury are very ______, but substances like rubber are very _______
S_A_V [24]

Answer:

electrons form the atoms f one material may move to the atoms of the other material. The movement of electrons from one atom to another changes the charge of the atoms. When an atom loses electrons, it is left with more protons than electrons, so it then has a positive charge. when an atom gains electrons, it has more electrons than protons so its charge is negative.

add charges, single electron dots, and/or pairs of dots as appropriate to show the lewis symbols for the most stable ion of each
Alja [10]

As - 8 dots and 3- charge, Se - 8 dots and 2- charge, Br - 8 dots and 1-, K - zero dots and +1 charge, Ca - zero dots and +2 charge, Ga - zero dots and +3 charge.

<h3>In the periodic table of the elements, what is its Lewis symbol?</h3>

The valence electrons of each element are represented by dots that surround their chemical symbol in a Lewis dot symbol. The Lewis dot symbol's dots correspond to the valence electrons, which correspond to the final digit of the element's group number as in periodic table.

<h3>What's an example of a Lewis symbol?</h3>

Two chlorine atoms, for instance, share one pair of electrons when they combine to form a chlorine molecule. According to the Lewis structure, each Cl atom contains one shared pair of electrons and pairs of electrons that aren't employed in bonds (known as lone pairs) (written between the atoms).
