There are 3 significant figures in this value, all values before and after the decimal point are significant. As there is a decimal point, the zeros trailing are also significant.
The mass of CO2 that would be produced is 144.03 g
From the equation of the reaction, the mole ratio of C2H4 input to CO2 produced is 1:2.
Recall that: mole = mass/molar mass
mole of 45.9 g C2H4 = 45.9/28.05
= 1.6364 moles
Thus: equivalent moles of CO2 = 1.6364 x 2
= 3.2727 moles
Mass of 3.2727 moles of CO2 = moles x molar mass
= 3.2727 x 44.01
= 144.03 g

Answer:
The answer is supposed to be "Electron cloud" or "Electon".
Answer:
Temperature, mass, and the type of material are factors that affect the thermal energy of an object.
Material with the higher specific heat will have more thermal energy than material with lower specific heat if they both have the same mass and temperature.
To increase the acceleration of the dog sled, increase the applied force on the sled and reduce the mass on the sled.
According to Newton's second law of motion, the force applied to an object is directly proportional to product of mass and acceleration of the object.
F = ma
where;
<em>a </em><em>is the </em><em>acceleration </em><em>of the dog sled</em>

To increase the acceleration of the dog sled:
- Increase the applied force on the sled.
- Reduce the mass on the sled.
