Answer:
The amount of final volume when mass of the system is constant =
0.526 L
Explanation:
Given data
= 500 mL = 0.5 L
= 740 torr
= 25 ° c = 298 K
= 50 ° c = 323 K
= 760 torr
From ideal gas equation we get
0.526 L = 526 ml
This is the amount of final volume when mass of the system is constant.

Answer:
162.4g of CO2 are produced
Explanation:
The combustion of ethanol, C2H5OH, occurs as follows:
2C2H5OH + 7O2 → 4CO2 + 6H2O
<em>Where 2 moles of C2H5OH produce 4 moles of CO2.</em>
<em />
To solve this question we need to convert the mass of ethanol to moles. Then, the moles of ethanol to moles of CO2 using the balanced reaction and to mass:
<em>Moles C2H5OH -Molar mass: 46.07g/mol-</em>
85.0g * (1mol / 46.07g) = 1.845 moles C2H5OH
<em>Moles CO2:</em>
1.845 moles C2H5OH * (4mol CO2 / 2mol C2H5OH) = 3.69 moles CO2
<em>Mass CO2-Molar mass: 44.01g/mol-:</em>
3.69 moles CO2 * (44.01g/mol) =
<h3>162.4g of CO2 are produced</h3>
Answer:c
Explanation: because it’s more reasonable
<em>Scientists believe water currents within the earth's mantle are slowly causing the plates above to move
</em>
<em></em>
<em>Answer: </em><u><em>True</em></u>

<u><em>EXplanation:</em></u>
<u><em /></u>
<u><em>The common, simplified explanation for why tectonic plates are moving is that they're carried along on currents in the upper mantle, the slowly flowing layer of rock just below the Earth's crust. Converging currents drive plates into each other. Diverging currents pull them apart</em></u>
