I don’t care about it tbh like I don’t even care about that stuff but the answer is 29272728
When placed in a container, the heaviest (most dense) will sink to the bottom and the lightest (least dense) will rise to the top.
Therefore, Gasoline would rise to the top.
Answer:
Noble gases, atoms which have complete filled outer orbits.
Explanation:
SInce, you have given no options elements like Neon, Helium,etc
Question options:
1. It cannot be determined without knowing which man is stronger.
2. The forces are unbalanced, and net force on the cart moves it to the left.
3. It cannot be determined because one man is taller than the other.
4. The forces are unbalanced, and net force on the cart moves it to the right.
Answer:
<em>2.The forces are unbalanced, and net force on the cart moves it to the left.</em>
Explanation:
In the image, two opposite forces acting on a rolling cart. The person on the right side exerting more force (50N) toward the left than the person on the left side (10N). The more the force applying on the object, it will drag on the followed direction.
It is because the person on the right side exerting force (50N) toward the left, rolling cart will moves to the left.
Answer:
120g
Explanation:
Based on the reaction, when 1 mole of propane and 5 moles of oxygen react, 3 moles of CO2 and 4 moles of H2O are produced. The ratio of production is 3 moles of CO2 per 4 moles of H2O.
Thus, we need to convert mass of water to moles using its molar mass:
Moles H2O (Molar mass: 18g/mol):
63g H2O * (1mol / 18g) = 3.5 moles H2O
Converting to moles of CO2:
3.5 moles H2O * (3 moles CO2 / 4 moles H2O) = 2.625 moles CO2
Mass CO2 (Molar mass: 44g/mol):
2.625 moles CO2 * (44g / mol) = 115.5g of CO2 are released
<h3>120g
