Explanation:
energy is change from one form to another called _energy conversion
energy can neither be created nor destroyed it can only be transformed from one form to another called --The law of conservation of energy
cause to change in form character or function called - convert
the last sentensce
energy transformation
Answer : The mass of lead in 139 g of is, 86.9 grams.
Explanation : Given,
Mass of = 139 g
Molar mass of = 331.2 g/mol
Molar mass of Pb = 207.2 g/mol
Now we have to calculate the mass of lead.
As, 331.2 g of has 207.2 g of lead
So, 139 g of has of lead
Thus, the mass of lead in 139 g of is, 86.9 grams.
Hello There!
When the ice melts, the water level will drop slightly but not much.
REMEMBER Ice expands so when ice melts, it shrinks back to the state of being liquid.
The statement which is an inference is; "the velocity of the stream is greatest near the outside of a meander."
The scientific method involves observations, hypothesis, experimentation and inference. The inference is a conclusion arrived at after conducting an experiment.
Hence, an inference is not a futuristic statement or a prediction but a statement of fact as gathered through the scientific study. The statement which represents an inference among the options is; "the velocity of the stream is greatest near the outside of a meander."

Answer:
Explanation:
usually, the first step is to calculate the moles but since that is already given in the question we can move onto the next step
<em><u>least molar ratio:</u></em>
<em>Cu = </em> = 3
P = = 1
thus, empirical formula =
