Answer:
A force is described as any influence that causes an object to undergo a change. Distance refers to how far an object travels over a period of time. The greater the force that is applied on an object the further distance that object will travel.

How could measuring the melting point of a solid help decide whether it was a mixture or a compound?
Answer: It can't.
Explanation:
In most cases, the melting point alone will not enable you to identify a compound. Millions of solid organic compounds, and their melting points, are known. Perhaps 10,000 of these will have the same melting point as your unknown compound.

What is the answer
The gravitational attraction between two objects is determined by the mass of the two objects and the:
A. Distance between the objects
B. Weight of the objects
C. Diameter of the objects
D. Density of the objects
Answer:
A. Distance between the objects
Explanation:
The gravitational attraction between two objects is determined by the mass of the two objects and the distance between the two objects.
According to Newton's law of universal gravitation:
"the gravitational force of attraction between two bodies is directly proportional to the product of the their masses and inversely proportional to the square of the distance between them".
F = [tex]\frac{Gm_{1}m_{2} }{r^{2} }[/tex]
F is the gravitational attraction
G is the universal gravitation constant
m is the mass
r is the distance
We can see that the gravitational attraction depends on the mass of the bodies and the distance between them.

Determine the mass of 6.43 moles of Barium.
Answer:
883.01261 grams
Explanation:
Answer:
Moles = Mass ÷ Ar
Mass = Ar × Moles
Mass = 137.327 × 6.43
Mass = 883.01g
Calculate the number of moles of neon gas in 8.15 x 10^24 atoms of neon gas.
1.35 moles Ne
0.135 moles Ne
135 moles Ne
13.5 moles Ne
Answer:
13.5 moles of Ne
Explanation:
1 mole of any gas contains 6.02 x 10²³ atoms of gas
6.02 x 10²³ atoms of neon is equal to 1 mole of neon .
8.15 x 10²⁴ atoms of neon is equal to 1 x 8.15 x 10²⁴ / 6.02 x 10²³ moles
= 8.15 x 10²⁴ / 6.02 x 10²³ mole o neon
= 13.5 moles of Ne .

help plz this is part b to my last question
Answer:
% error Aluminum: 0.34%
% error Steel: 16.67%
% error Lead: 23.08%
Explanation: Given our observed values of specific heat, to find the % error, we must know the true values as well. % error can be defined as, % error = |observed value - true value | / true value.
Our given data to solve this problem is as follows:
Aluminum Specific Heat Observed Value: 0.9 (given), Aluminum Specific Heat True Value: 0.897 (research).
Steel Specific Heat Observed Value: 0.49 (given), Steel Specific Heat True Value: 0.42 (research).
Lead Specific Heat Observed Value: 0.16 (given), Lead Specific Heat True Value: 0.13 (research).
___________
Since we have all the information, just subtract the true value from the observed value, and divide by the true value.
Aluminum Specific Heat % error:
observed value - true value / true value →
0.9 - 0.897 / 0.897 = 0.003 / 0.897 = 1/299 ≈ 0.34 %
Steel Specific Heat % error:
observed value - true value / true value →
0.49 - 0.42 / 0.42 = 0.07 / 0.42 = 1/6 ≈ 16.67%
Lead Specific Heat % error:
observed value - true value / true value →
0.16 - 0.13 / 0.13 = 0.03 / 0.13 = 3/13 ≈ 23.08%

Two liters of hydrogen gas are stored at a
pressure of 100 kPa. If the temperature
does not change, what will the volume
of the gas be when the pressure is
decreased to 25 kPa?
Answer:
the volume will expand
Explanation:
gas under pressure contracts, and expands with a lesser pressure
The volume of the hydrogen gas at 25 kPa is 8 Liters.
Explanation:
Given:
At constant temperature, 2 liters of hydrogen gas at 100kPa pressure.
To find:
The volume of the hydrogen gas at 25kPa.
Solution:
The initial pressure of the hydrogen gas =[tex]P_1=100 kPa[/tex]
The initial volume of the hydrogen gas at 100 kPa =[tex]V_1=2 L[/tex]
The final pressure of the hydrogen gas =[tex]P_2=25 kPa[/tex]
The final volume of the hydrogen gas at 25kPa = [tex]V_2=?[/tex]
Using Boyles law:
[tex]P_1V_1=P_2V_2\\100kPa\times 2 L=25 kPa\times V_2\\V_2=\frac{100 kPa\times 2L}{25 kPa}=8L[/tex]
The volume of the hydrogen gas at 25 kPa is 8 Liters.

Can an Atom be broken down into a smaller substance? Yes or No Explain.
Answer:
Yes
Explanation:
A atom is made out of 3 elements, protons which are positive charges, electrons which are negative charges that swirl around the atom, and a neutron with a neutral charge. The nucleus of the atom is basically the center of the atom.
What is the relationship between the volume of a gas and the Kelvin temperature (at
constant pressure)?
They are the same.
They are inversely proportional to each other
They are directly proportional to each other.
They are independent of each other.
Define a force.......
Answer:
Gravitational Force.
Gravitation is the agent that gives weight to objects with mass and causes them to fall on the ground when dropped.
Answer:
A force is the strength or energy as an attribute of physical action or movement.
Explanation:
In smaller words, a force is a form of energy caused from a push or a pull on an object. A force happens when two objects interact with each other. For example, when you throw a ball you are using force.

How many atoms in 134 moles of an element B?
Answer:
8.06966961e+25
Explanation:
Atom = Mole / 6.0221415E+23
1 Mole = 6.0221415E+23 Atom
Answer:
8.06948e+25 atoms
Explanation:
mole = number of particles/avogadro number
number of atoms = mole × avogadro number
number or atoms = (134) x (6.022× 10²³) = 8.06948e+25 atoms
