True!
Energy can change from Potential to Kinetic and so on.
This is actually called energy transformation!
Answer:
V = 267.2 L
Explanation:
Given data:
Volume of balloon = ?
Mass of helium = 2.50 g
Temperature of gas = 180°C
Pressure = 0.87 atm
Solution:
Number of moles of helium:
Number of moles = mass/molar mass
Number of moles = 2.50 g/ 4 g/mol
Number of moles = 0.625 g
Volume of helium:
PV = nRT
R = general gas constant = 0.0821 atm.L/mol.K
0.87 atm× V = 0.625 mol × 0.0821 atm.L/mol.K×453 K
V = 232.45 atm.L /0.87 atm
V = 267.2 L
I can help. First you want to write out each reactant and product with enough space to write in coefficients. Then box the reactants and products to emphazise how the elements shouldnt change. Afterwards, draw a line in front of the box for you to write in the coefficients.Now we srart balancing. To make things easier, you should always follow the method of : (Metals, Nonmetals,Oxygen,Hydrogen) in that order. By balancing each elememt/chemical this way it should make balancing them easier.
So to acryally perform it you're going to look at your first element (while still following the method) and then look over onto the other side to see what coefficient to place. Then after that element is balanced, you move onto the next element. Remember that everytime you balance an element, start over to make sure all of the other elements are still balanced before proceeding.
Answer:
The greenhouse effect
Explanation:
The greenhouse effect is a straightforward method that heats the Earth's exterior. When the Sun's rays touch the Earth's environment, some of it is bounced back to space and the rest is grasped and re-heated by greenhouse gases. The consumed energy heats the environment and the exterior of the Earth.
Explanation:
Answer is that : no heat will flow
