Answer:
Oxygen is the limiting reactant.
Explanation:
Based on the reaction:
C₁₂H₂₂O₁₁ + 12O₂ → 12CO₂ + 11H₂O
<em>1 mole of sucrose reacts with 12 moles of oxygen to produce 12 moles of CO₂ and 11 moles of H₂O.</em>
<em />
10.0g of sucrose (Molar mass: 342.3g /mol) are:
10.0g C₁₂H₂₂O₁₁ × (1mole / 342.3g) = 0.0292 moles of C₁₂H₂₂O₁₁
And moles of 10.0g of oxygen (Molar mass: 32g/mol) are:
10.0g O₂ × (1mole / 32g) = 0.3125 moles of O₂
For a complete reaction of 0.0292 moles of C₁₂H₂₂O₁₁ you need (knowing 12 moles of oxygen react per mole of sucrose):
0.0292 moles of C₁₂H₂₂O₁₁ × (12 moles O₂ / 1 mole C₁₂H₂₂O₁₁) = <em>0.3504 moles of O₂</em>
As you have just 0.3125 moles of O₂, <em>oxygen is the limiting reactant.</em>
If the ball is dropped from a higher height than the feather their rates of displacement (acceleration) could match.
One of the major lab accidents was of fire when a gas was exposed to heat.
<u>Explanation:</u>
The mishaps or the accidents that take place in the laboratory while experimenting are known as the laboratory accidents. Some of the laboratory accidents are chemical spills, fire or explosion, personal injuries and so on.
One of the major lab accidents was of fire when methane gas was exposed to heat. Because of this it led to fire during the experiment. At the time of the experiment, the personal protective equipment worn were the lab gloves, lab coat and the protective eye care. To avoid such kind of accidents, more care and attention should be paid while experimenting. It should be made sure that there are proper equipment in case any accident takes place.
Answer:
Shear stress
Explanation:
Shear stress occurs in what we call transform boundaries. Transform boundaries happen when two tectonic plates slide against each other.
There are 3 main types of stress and shear stress is one of them.
Additional information ahead, continue reading if you'd like to know more.
Compression stress occurs when two tectonic plates are convergin g (at convergent boundaries).
Tension stress occurs when two tectonic plates are diverging, or when they are moving apart, (at divergent boundaries).
Answer: C, an apple staying at rest on the ground.
Explanation: When one or more unbalanced forces are acting on an object, it causes change (eg. the apple falling on the ground would be a result of gravity being stronger than the kinetic energy that the tree is putting on the apple). Even in D, the apple is not moving, but the tree branch is still exerting force to keep the apple hanging there.
PS: I studied net forces last year. Hope this helps!
