Compare the mineral halite (NaCl, hardness of 2.5) to diamond which is pure carbon chemically bonded to itself in a network. Are the mineral's chemical bonds covalent, polar covalent, or ionic? Which mineral is harder?
On Mohs scale, isn't diamond assigned a $10$ on the basis of hardness? Halite is almost a purely ionic material.

Is $CO_2$ an ionic salt or covalent molecule?
$CO_"2"$ is made up of: - 1 carbon atom, - 2 oxygen atom. Carbon and oxygen are non-metals, thus we know carbon dioxide is a covalent compound....

Describe the uniqueness of a covalent bond. How is it similar to an ionic bond? How is it different from a covalent bond?
Both bonds result in forming of differentiating properties and structures. Atoms react in order to achieve stability. However, covalent bonds have a unique property that ionic bonds do not...

Is $CuCl_2$ an ionic salt or covalent molecule?
Chlorine has a high electro negativity of 3.0. Copper like most metals has a low electro negativity, So the is ionic making the compound an ionic salt.

Consider the following element combinations. Classify the bonds formed between each pair as ionic, polar covalent, or nonpolar covalent qualitatively based solely on each element's position on the periodic table? Do not conduct calculations.
Something worth knowing about deciding between nonpolar and polar is that only two of the same element can form an ideally nonpolar bond. With this in mind, the $"Br"-"Br"$...

The electronegativity is 2.1 for H and 1.8 for Si. Based on these electronegativities, $SiH_4$ would be expected ?A) be ionic and contain H+ ions (B) be ionic and contain H- ions (C) have polar covalent bonds with a partial negative charges on the H atoms
The answer is (C) have polar covalent bonds with a partial negative charge on the hydrogen atoms. If you only go by the options given, the answer will be obvious...

Do we consider that the intramolecular bond of HCl changes from covalent to ionic when it's dissolved in water?
Because Cl is more electronegative than H, the gaseous molecule HCl contains a polar covalent bond in which the chlorine atom has a greater attraction towards the pair of electrons....

A 50.0-kg mixture of salt and water is 15.0% (by mass) salt. What is the mass of salt and water in the mixture?
You know that your mixture is $15.0%$ salt by mass, so make sure that you understand what that means before moving forward. For a component of a mixture, its...

If 5.00g of MnO2 reacts w/ 25.0mL of 6M HCL calculate the mass of Cl2 produced? I figured out MnO2 but stuck with HCl. I did 25mL HCl x(0.001L/1mL)x (6mol HCl/1 L) but I don't know where I should go now?
This reaction will produce $"2.63 g"$ of $Cl_2$ gas. Start with the balanced chemical equation, that is a must for any problem. $MnO_(2(s)) + 4HCl_((aq)) -> Cl_(2(g)) +...

A solution is prepared from $25*g$ of salt dissolved in $1*L$ of water. If the salt is an hydrate of sodium thiosulfate, how many water molecules are associated with this salt?
$Na_2S_2O_3*5H_2O$ is the common laboratory reagent, this so-called pentahydrate forms large sugary crystals so it is easy and convenient to handle. The formula mass of this material is $248.18*g*mol^-1$ (i.e....
