Is the weighted average mass of an atom of an element based on the relative of natural abundance of that isoptopes of elements.
It holds A. Less water than when it is warmer.
Answer:
Sunlight allows plants to perform photosynthesis, a process which is required for plant growth and health. ... Plants that are denied sufficient light will eventually lose their color and die. Plants deprived of light will grow upward, stretching their stems more rapidly that usual, searching for light.
Answer:
1 meter for this wave
Explanation:
Amplitude is the height of the wave from the midline to the crest
Answer:
The change in internal energy for the system = - 78.87 KJ = - 79 KJ to 2 s.f
Explanation:
The first law of thermodynamics states that energy can neither be created nor destroyed but can only be transformed from one form to another.
It goes further to explain that change in the internal energy of a system (ΔU) is the sum of heat exchanged (Q) and the work done (W) by the system or on the system.
If work is done by the system, sign of work is ‘-’, if work is done on the system, the sign of work is ‘+’.
If heat is released by the system, the sign of q is ‘-’. And if heat is gained by the system, then the sign of q is ‘+’.
ΔU = Q + W
Q = 130 J
W = - 79 KJ = - 79000 J
ΔU = 130 - 79000 = - 78870 J = - 78.87 KJ = - 79 KJ
