Find the number of moles of water that can be formed if you have 154 mol of hydrogen gas and 72 mol of oxygen gas.
Answer:
The answer is 144 mol.
Explanation:
"72 mol of oxygen will form only 144 mol of water, and 10 mol of hydrogen remain in excess, so the limiting reactant is oxygen and hydrogen is in excess."

Answer:
If two forces act on an object in the same direction, the net force is equal to the sum of the two forces. This always results in a stronger force than either of the individual forces alone
A person rides in an elevator.
What is the equal and opposite force for the Earth's force of gravity pulling down on the person as
described by Newton's third law?
Answer:
Normal force
Explanation:
normal force always perpendicularly points away from a surface
Normal force is the equal and opposite force for the Earth's force of gravity pulling down on the person as described by Newton's third law.
What is force?Force is defined as a cause which is capable of changing the motion of an object. It can cause an object which has mass to change it's velocity. It is also simply a push or a pull . It has both magnitude as well as direction.Hence, it is a vector quantity.
It has SI units of Newton and is represented by'F'.Newton's second law states that force which acts on an object is equal to momentum which changes with time. If mass of object is constant, acceleration is directly proportional to net force acting on an object.
The concepts which related to force are thrust and torque .Thrust increases the velocity of an object and torque produces change in rotational speed of an object.

What evidence do you need to determine that two rocks have some similar minerals because the minerals from the original rock was eroded then it was later compressed with other minerals to form a different rock.
Answer:
It comes from same parent material.
Explanation:
The two rocks have some similar minerals which indicates that they are comes from the same parent material but with the passage of time it is mixed with other minerals due to which they are some different in composition from one another so we can conclude that they comes from the same parent material due to the presence of some similar minerals.

Write the orbital notation for each of the following: (Be sure to label your sublevels)
a) O b) Sc
Explanation: In writing the electron configuration for oxygen the first two electrons will go in the 1s orbital. Since 1s can only hold two electrons the next 2 electrons for O go in the 2s orbital. The remaining four electrons will go in the 2p orbital. Therefore the O electron configuration will be 1s22s22p4.
A popular radio station broadcasts with a frequency of 94.7 MHz. What is the
wavelength of the broadcast? (1 MHz = 1x106 Hz).
Answer:
λ = 0.032×10² m
Explanation:
Given data:
Frequency of broadcasts = 94.7 MHz
Wavelength of broadcasts = ?
Solution:
Frequency of broadcasts = 94.7× 10⁶ Hz
Formula:
Speed of wave = frequency × wavelength
3×10⁸ m/s = 94.7× 10⁶ Hz × λ
λ = 3×10⁸ m/s /94.7× 10⁶ Hz
Hz = 1/s
λ = 0.032×10² m

Which continents were most difficult to place? Why?
Answer:
Antarctica and Australia
Explanation:
Since both of these are furthest south it is more difficult to measure the correct distance between them.
The continents that were the hardest to locate were Antarctica and Australia because they are both the ones that are the furthest south, making it more challenging to calculate the proper distance between them.
A continent is a huge, continuous landmass on the surface of the Earth, typically divided by oceans or other major bodies of water. Africa, Antarctica, Asia, Europe, North America, Australia, and South America are the seven continents of the world. In terms of topography, climate, culture, and biodiversity, each continent is distinct. For instance, Asia is home to the Himalayas, the world's highest mountain range, while Africa is renowned for its huge savannas and diverse animals. While Australia is well known for its distinctive flora and wildlife, Europe is known for its historical sites and artistic creations.

Why is gunshot residue important for a forensic scientist? What are the potential complications with this type of evidence?
FORENSICS
Answer:
Gunshot residue is important to forensic scientists because it can help measure the firing distance of a weapon, or if someone has fired a weapon lately based on what's on their hands. The potential complications of this evidence include it being uncertain if the residue is from another firing. This type of evidence can also be uncertain in a courtroom when firing distance is drawn into question.
