Answer:
b. 23.3g
Explanation:
Based on the reaction:
CH₄ + 2O₂ → CO₂ + 2H₂O
To find the mass of CO2 produced we must find, as first, the limiting reactant. With limiting reactant we can find the moles and the mass of CO2 as follows:
<em>Limiting reactant:</em>
For a complete reaction of 0.53 moles of CH4 are necessaries:
0.53 moles CH4 * (2mol O2 / 1mol CH4) = 1.06 moles O2.
As there are 1.5 moles, CH4 is limiting reactant.
<em>Moles CO2:</em>
1 mole of CH4 produce 1 mole of CO2. That means the moles of CO2 formed are 0.53 moles.
<em>Mass CO2 (Molar mass: 44.01g/mol)</em>
0.53 moles CO2 * (44.01g / mol) =
b. 23.3g
Answer:
54.616
Explanation:
8.647 + 45.969
or rewrite for easier look:
45.969 +
8.647 =
54.616

Twice as much more will the freezing point of water be lowered in beaker a than in beaker b.
<h3>What determines freezing point?</h3>
A liquid's freezing point rises if the intermolecular interactions between its molecules are strong. The freezing point, however, drops if the molecules of inter - molecular are minimal. The process through which a substance transforms from a liquid into a solid is known as freezing.
<h3>How significant is freezing point?</h3>
Freezing points play a big role in occupational safety. A chemical may perhaps turn harmful if held below its freezing point. A critical safety benchmark for assessing the effects of worker exposure to cold environments is the freezing point.

Answer:
Kinetic energy
Explanation:
The kinetic energy of a particle is directly proportional to the temperature of it. An increase in temperature increases the speed in which the molecules move, causing t[he particles to collide with the walls of their containers.
