Answer:

Intake, compression, power, exhaust

Explanation:

To generate power, an engine must continually cycle through the same four stages of operation.

Intake: A mixture of air and fuel is drawn into the cylinder.

Compression: The piston rises and compresses the mixture.

Power: The spark plug ignites the mixture and causes an explosion.

Exhaust: The leftover gases are released from the cylinder.

Answer:

Intake, compression, power, and exhaust

Explanation:

A four-stroke cycle engine is an internal combustion engine that utilizes four distinct piston strokes (intake, compression, power, and exhaust) to complete one operating cycle. The piston make two complete passes in the cylinder to complete one operating cycle.

1.5mol C3H8 from C3H8+5O2-->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 $\large \boxed{\textbf{200 g CO}_{\mathbf{2}}}$}

Which correctly summarizes the trend in electron affinity?it tends to be very high for group 2.it tends to be more negative acro
STALIN [3.7K]
The statement that correctly summarizes the trend in electron affinity is the second option: it tends to be more negative across a period".<span> Electron affinity is the energy absorbed or released by a neutral atom when it absorbs an electron. The more negative the electron affinity the higher the affinity of the atom for an additional electron. So as the electronegativity trends to increase across a period, indicating that the atoms of the left side pull stronger the electrons, the fact that the electron affinity is more negative across a period tells that the atoms to the left accept better an additional electron.</span>
