On a summer day in Breckenridge, Colorado, the atmospheric pressure is 525 mm Hg. What is this air pressure in West Chester, Pennsylvania as it relates to the pressure in Colorado?
a. The same as in Colorado
b. Lower than in Colorado
c. Higher than in Colorado
d. There is not enough information to tell.
Answer:
Option B
Explanation:
The atmospheric pressure in West Chester, Pennsylvania is lower than the pressure on any summer day in Breckenridge, Colorado
Colorado is 1.6 kilometers above sea level while Pennsylvania is 0.33 kilometers above sea level.
The higher a place is above sea level, the higher is the air pressure.
Hence, option B is correct

what are the respective coefficients needed to balance the equation below _N2(g) + _H2(g) --> _NH3(g)
In the balanced equation, the mass of reactant is exactly equal to the mass of product. The respective coefficients needed to balance the equation is N₂(g) + 3H₂(g) ⇒ NH₃(g) .
What is balanced equation ?A chemical equation that is balanced has equal amounts of each element's atoms on both sides of the equation and conserves mass.
Because mass cannot be generated or destroyed, according to the rule of conservation of mass, a chemical equation must always be in balance.
The Law of Conservation of Mass is followed by a balanced equation. This is a crucial scientific guiding principle. Finally, a balanced equation enables us to forecast the quantity of reactants and products that will be produced. Sort of crucial if you're attempting to determine how much fuel to supply a spacecraft traveling to Mars
Thus, the balanced equation is N₂(g) + 3H₂(g) ⇒ NH₃(g) .

molecular mass meaning in chemistry?
Answer:
Molecular mass is a number equal to the sum of the atomic masses of the atoms in a molecule.
Explanation:
The molecular mass gives the mass of a molecule relative to that of the 12 C atom, which is taken to have a mass of 12. Hence why Molecular mass is a number equal to the sum of the atomic masses of the atoms in a molecule.
Q3. When copper (II) chloride reacts with silvernitrate, copper (II) nitrate and silverchloride are formed.Write the balanced equation for the reaction given above:A.CuCl2(aq) + 2 AgNO3(aq) →Cu (NO3)2(aq) + 2 AgCl(s)B.CuCl2(aq) + NaNO3(aq) →Cu (NO3)2(aq) + AgCl(s)C.CuCl2(aq) + 2 NaNO2(aq) →Cu (NO2)2(aq) + 2 AgCl(s)D.CuCl(aq) + NaNO3(aq) →Cu NO3(aq) + AgCl(aq
Answer:
See explanation
Explanation:
When we are writing chemical reaction equations, we must ensure that such equations are balanced. That is, the number of atoms of each element on both sides of the reaction equation are exactly the same.
After we identify the formula of each compound in the reaction, then we proceed the write the balanced reaction equation as follows;
CuCl2 + 2AgNO3 -------> Cu(NO3)2 + 2AgCl

How do the mass number and atomic change as a particle goes through beta decay
Answer:
The atomic mass number does not change because a beta particle has a much smaller mass than an atom. The atomic number goes up because a neutron has turned into an extra proton, however in beta decay a fast-moving electron is fired out of the nucleolus

However, in day-to-day experience, the strangeness of Einstein's ideas doesn't help us, and Newton's notions do just fine. In everyday Life, when gravity isn't especially intense, Newton's and Einstein's ways of thinking lead to similar results. The two explanations work like different languages that express the same thing.

Would a rollercoaster have the greatest kinetic energy at the top of the highest hill or at the bottom on the highest hill
Answer:
The rollercoaster has the lowest kinetic energy at the top of the hill.
The rollercaoster has the highest kinetic energy at the bottom of the hill.
Explanation:
The kinetic energy of any solid body in motion is usually computed using this formula:
K.E = [tex]\frac{1}{2}mv^2[/tex]
From this, we can see that it varies based on two major parameters - The mass of the moving object and the velocity of the moving object.
We can assume that the mass of the rollercoaster is constant since no one gets off and it does not shrink in its size during the ride.
This means that the variations in the K.E are mainly coming from its velocity.
At the top of the hill, the rollercoaster is moving at its slowest pace. hence, it has the lowest kinetic energy at the top of the hill.
However, at the bottom of the hill, the rollercoaster is moving its fastest, hence it has the highest kinetic energy at the bottom of the hill.
