When a compound such as X2Z4 is created, what would be the<br> correct simplified chemical formula?
Shtirlitz [24]

Answer:

XZ2

Explanation:

There are different ways in which compounds can be represented. Broadly, we have three different types of formula;

- Structural formular: This shows how th atoms in te compound are connected to each other.

- Molecular formular: This shows the actual number of atoms of element present in the compound

- Empirical Formular: This is the simplest formular of a compound. It basically shows the number of atoms in simple ration to each other.

This question requires us to input the empirical formular;

X2Z4

The ratio of the elements is; 2 : 4 which can be simplified into 1 : 2

This means the empirical formular is XZ2

Caculate the number if moles of the following: 800. g of Ca
Maru [420]
Mole   is  equal  to   mass  of  the  element  divided  by   molar  mass  of  the  element.  that   is
mole=mass/molar  mass
From  periodic  table calcium  has  a   molar  mass  of  40   g/mol
moles  is   therefore  =800g/40g/mol=20moles

Why does surface area of a reactant influence the rate of the reaction?
telo118 [61]

because it can influence how frequently and sufficiently the particles collide depending on the space it has to do so, for example a large surface area would be have a slower rate of reaction and a lower temperature. (the rate of reaction in terms of concentration, it is diffused from high to low)
