Answer:
There are 36 grams in 4.00 moles of Carbon.
Explanation:
In order to convert from moles of a substance into grams of the same substance, we need to use the substance's molar mass.
That means that in this case we use the<em> molar mass of Carbon</em>:
- 4.00 mol * 12 g/mol = 36 g
Thus, there are 36 grams in 4.00 moles of Carbon.
Answer:
its endothermic .
because your using a cooling process instead of a heating process if it was a heating process it would be exothermic
Answer: All of the above!
Explanation:
Water- moves across soil and breaks down pieces of rocks
Wind- can blow materials around, such as rocks or sand. Also it can dry out soil.
Ice- carries broken rocks or soil to different places and can cause glacier erosion.
Gravity- thinking about it, earth is the one place with gravity so if gravity changed it can cause objects to move. Also it determines the shape of the earth because the center has more gravitational pull. This gives it a very round shape.
Organisms- more animals means increase of destruction of plants, which can lead to faster erosion.
Sun- the sun is very important. If the earth didn’t get any sunlight there wouldn’t be any life on the planet itself. Which makes it lack rocks, plants, weather, and the atmosphere.
And by that point it’s just not none of the above.
Answer:
6 atm
Explanation:
Using the formula P1V1=P2V2
P1= Initial Pressure
V1= Initial Volume
P2= Final Pressure
V2= Final Volume
And knowing that at stp gas will always be at 1 atm
250L(P2) = 1500
P2= 6 atm
Taking into account the definition of potencial energy, the object's mass is 14.96 kg.
<h3>Potential energy</h3>
Potential energy is the energy that measures the ability of a system to perform work based on its position. In other words, this is the energy that a body has at a certain height above the ground.
Gravitational potential energy is the energy associated with the gravitational force. This will depend on the relative height of an object to some reference point, the mass, and the force of gravity.
Then the expression applied to the gravitational energy of the object is:
Ep= m×g×h
where:
- Ep is the potential energy in joules (J).
- m is the mass in kilograms (kg).
- h is the height in meters (m).
- g is the acceleration of fall in m/s² (approximately 9.81 m/s²).
<h3>Object's mass</h3>
In this case, you know:
- Ep= 734 J
- m= ?
- g= 9.81 m/s²
- h= 5 m
Replacing in the definition of potential energy:
734 J= m× 9.81 m/s² ×5 m
Solving:
734 J= m× 49.05 m²/s²
m= 734 J÷ 49.05 m²/s²
<u><em>m= 14.96 kg</em></u>
Finally, the object's mass is 14.96 kg.
