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.
Answers
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."

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?
Answers
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.
Answers
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.

Percentage of hydrogen = 6%
Percentage of carbon = 24%
Percentage of chlorine= 70%
Empirical formula = ?
Solution:
Number of gram atoms of H = 6/ 1 = 6
Number of gram atoms of C = 24 /12= 2
Number of gram atoms of Cl = 70/ 35.45 = 2
Atomic ratio:
C : H : Cl

A popular radio station broadcasts with a frequency of 94.7 MHz. What is the
wavelength of the broadcast? (1 MHz = 1x106 Hz).
Answers
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?
Answers
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.

Which of the elements below has the largest electronegativity? Na, Mg, S, P?
HURRY!!!
Answers
Answer:
Electronegativities generally decrease from top to bottom within a group due to the larger atomic size.
Of the main group elements, fluorine has the highest electronegativity (EN= 4.0) and cesium the lowest (EN=0.79).
Explanation:
Sulfur has the largest electronegative element. Therefore, option C is correct.
What is electronegativity?Electronegativity is a measure of an atom's ability to attract electrons toward itself in a covalent bond, and it generally increases as you move across a period from left to right in the periodic table.
The type of bond that exists between atoms will depend on the electronegativity of the system.
Out of the given elements, S (sulfur) has the largest electronegativity. Sulfur has an electronegativity value of 2.58 on the Pauling scale, while Na (sodium) has an electronegativity value of 0.93, Mg (magnesium) has an electronegativity value of 1.31, and P (phosphorus) has an electronegativity value of 2.19. Therefore, option C is correct.
