Molar mass acetic acid:
C₂H₄O₂ = 12 * 2 + 1 * 4 + 16 * 2 = 60.
n = mass / molar mass
3.00 = m / 60.0
m = 3.00 * 60.0
m = 180 g of <span>C₂H₄O₂
hope this helps!</span>
Answer:
A) Devices that transfer kinetic energy have a source of power that is in motion
Kinetic energy is the energy in motion, as such, a device that transfers kinetic energy transfers the energy the power source has into other energy forms
B) Kerosene does not easily cold start like diesel which can burn after compression
C) The first law of thermodynamics states that energy is conserved and it can neither be created nor destroyed, but can be changed from one form to another.
Therefore, when energy is not available in a given location or body, it cannot be obtained from that body or location
Explanation:
Hear n = 1000 to n = 2 pairs of quantum states of hydrogen has the biggest energy difference between the states
A quantum state is a mathematical concept used in quantum physics that gives a probability distribution for the results of each potential experiment on a system. All that can be predicted about the behaviour of the system is exhausted by knowledge of the quantum state and the laws governing the system's evolution across time. Another quantum state is a combination of quantum states. All other quantum states are known as mixed quantum states, whereas pure quantum states are those that cannot be described as a combination of other states. A ray in a Hilbert space over the complex numbers can represent a pure quantum state, but density matrices, which are positive semidefinite operators acting on Hilbert spaces, can represent mixed states.To know more about ray, visit to: -brainly.com/question/17491571#SPJ4
