When butane is burned, it usually produces carbon dioxide and water. If there is a shortage of oxygen, the flame is not as hot a

nd black carbon solids are formed (also called soot). How did the experiments in the lab demonstrate these flames?

Complete and incomplete combustions are refer to these flames.

This is because complete combustion occurs when the combustion occurs with full supply of oxygen whereas incomplete combustion occurs when something is burn in the presence of limited or very low amount of oxygen. Due to difference in the concentration of oxygen both flames produces different products in the end from the same reactant so we can conclude that these flames are different i.e. complete and incomplete combustions.

This number tells you the number of each type of atom in a compound.
KonstantinChe [14]

Answer:

avogadro's constant

Explanation:

this is the fixed number of the atoms in the molecule of an element

avogadro's law states that equal volumes of gases<em> </em><em>at</em><em> </em><em>the</em><em> </em><em>same</em><em> </em><em>temperature</em><em> </em><em>and</em><em> </em><em>pressure</em><em> </em><em> </em><em>contain</em><em> </em><em>equal</em><em> </em><em>numbers</em><em> </em><em>of</em><em> </em><em>molecules</em><em> </em>

<em>that</em><em> </em><em>is</em><em> </em><em>all</em><em> </em><em>gases</em><em> </em><em>with</em><em> </em><em>same</em><em> </em><em>temperature</em><em> </em><em>and</em><em> </em><em>pressure</em><em> </em><em>will</em><em> </em><em>always</em><em> </em><em>have</em><em> </em><em>equal</em><em> </em><em>numbers</em><em> </em><em>of</em><em> </em><em>molecules</em><em> </em>

How much HCI exists in 275 mL of 0.83 M<br> solution of HCI?<br> Answer in units of mol.
zubka84 [21]

Answer:

0.22825mol HCl

Explanation:

M=\frac{moles}{liters} \\

0.83M HCl = \frac{x(mol)}{0.275L}

1. Cross multiply!

\frac{0.83M}{1} =\frac{x}{0.275L}

x = 0.22825 mol HCl

1.5mol C3H8 from C3H8+5O2--&gt;3CO2+4H2O .how many grams of carbon dioxide are produced
koban [17]

Answer:

\large \boxed{\text{200 g CO}_{{2}}}

Explanation:

We will need a balanced equation with masses, moles, and molar masses, so let’s gather all the information in one place.

Mᵣ:                                 44.01

            C₃H₈ + 5O₂ ⟶ 3CO₂ + 4H₂O

n/mol:    1.5

1. Calculate the moles of CO₂

The molar ratio is 3 mol  CO₂:1 mol C₃H₈

\rm  \text{Moles of CO}_{2} = \text{1.5 mol C$_{3}$H}_{8} \times \dfrac{\text{3 mol CO}_{2}}{\text{1 mol C$_{3}$H}_{8}} =\text{4.5 mol CO}_{2}

2. Calculate the mass of CO₂.

\text{Mass of CO}_{2} = \text{4.5 mol CO}_{2}  \times \dfrac{\text{44.01 g CO}_{2}}{\text{1 mol CO$_{2}$}} = \textbf{200 g CO}_{\mathbf{2}}\\\text{The reaction will form $\large \boxed{\textbf{200 g CO}_{\mathbf{2}}}$}
