Answer:

Filtration is a process to separate heterogenous mixture even some homogenous.

To apply these you must use filters or filtrators such as tea bags, coffe filtrators, and other materials.

4.2g of cerium reacted with oxygen to form 5.16g of an oxide of cerium. Find

olganol [36]

Answer:

CeO₂

Explanation:

Hello!

In this case, since we are given the mass of both cerium and the cerium oxide, we can first compute the moles of cerium and the moles of oxygen as shown below:

$n_{Ce}=4.2gCe*\frac{1molCe}{140.12gCe}=0.03molCe\\$

$m_O=5.16g-4.2g=0.96gO\\\\n_O=0.96g*\frac{1molO}{16.0gO} =0.06molO$

Now, we simply divide each moles by 0.03 as the fewest moles in the formula to obtain the simplest formula (empirical formula) of this oxide:

$Ce=\frac{0.03}{0.03}=1\\\\O =\frac{0.06}{0.03}=2$

Thus, the formula turns out:

$CeO_2$

Use Lewis diagrams to show how electrons are shared to form covalent bonds in compounds wit the following atoms. Write the formu

bixtya [17]

The Lewis structure/diagram for CH2O (aka Formaldehyde) can be written in either of the following ways shown in the picture.
The dots represent electrons in the valence shell of the atom (the outermost shell). The green dots are electrons that belong to the Oxygen atom, the blue belong to the Carbon atom, and the pink belong to the Hydrogen atoms.
Covalent bonds are bonds between atoms where atoms share electrons with each other. Atoms bond because they obey the octet rule ( the rule states that most atoms of main-group elements tend to want 8 electrons in their valence shells).
Oxygen has 6 valence electrons, Carbon has 4, and Hydrogen has 1. H does not follow the octet rule, but C and O do, so the atoms are arranged in this way so that the O and C atoms have a full octet of electrons in their valence.
