Chemistry

ella [17]3 years ago

Ionic compounds are neutral compounds made up of positively charged ions called cations and negatively charged ions called anions. For binary ionic compounds (ionic compounds that contain only two types of elements), the compounds are named by writing the name of the cation first followed by the name of the anion.

mrs_skeptik [129]

High temperature and pressure produce the highest rate of reaction. However, this must be balanced with the high cost of the energy needed to maintain these conditions. Catalysts increase the rate of reaction without affecting the yield. This can help create processes which work well even at lower temperatures.

I hope this helps you.

Many metals react with oxygen gas to form the metal oxide. for example, calcium reacts as follows. 2 ca(s) + o2(g) → 2 cao(s) yo
aniked [119]
<span>(a) Assuming the amount of O2(g) is not limiting the reaction, a mass of 4.23g of Ca(s) will produce an equal mass of CaO(s), hence it will produce 4.23g of CaO(s). According to their respective molar masses, we have the following CaO molar mass : Molar mass of Ca + Molar mass of O = 40.1 + 16 = 56.1 g/mol 4.23g of Ca will then produce : 4.23 / 56.1 = 0,07540107 mol of CaO. (b) With the same reasonment as above, and assuming the amount of Ca is not limiting, we have : 2.87g of O2 will produce : 2.87 / 56.1 = 0,051158645 mol of CaO. (c) From (a) and (b) answers, we can conclude that the reactant that produces less mol of CaO is limiting the reaction. Hence following the given masses, O2 is the limiting reactant. (d) Knowing the molar mass of CaO is 56.1 g/mol and knowing that O2 is the limiting reactant, we also know the reaction can produce a maximum of 0,051158645 mol of CaO can be produced. So we can conclude we will produce : 56.1 * 0,051158645 = 2.87g of CaO.</span>

How are elements<br> and compounds<br> different?
Nataliya [291]

Answer:

Elements only contain one type of atoms while compounds contain two or more types of atoms.

Explanation:

An example of an element is sodium --> Na (only Na atoms)

An example of a compound can be water --> H2O (contain H and O atoms)

*But the particles within a compound are all the same.
