The butter contains a new arrangement of atoms. It’s a physical change therefore it cannot change into a different substance and it can turn into a solid again as physical changes just the property of a substance. The butter also remains as butter so there would still be the same number of atoms.

Why do some cells make food molecules?
kvasek [131]

Answer:

All living cells release energy from food  molecules through cellular breathing and/or fermentation. Some cells make food molecules using light energy through the process of (making food from light).

Making food from light- Photosynthesis

Breathing- Respiration

All living units give out power for a given time from food small complex units through formed of small units breathing and or fermentation. Some units make food small complex units using light power for a given time through the process of (making food from light).

An FAS calibration curve (absorbance, y-axis vs. FAS in g/mL) gave an equation he regression line of: y-3678(x)+0.056. If an unk
mezya [45]

Answer:

FAS concentration = 1.61*10^-4M

Explanation:

Beer Lambert's law relates the absorbance (A) of a substance to its concentration (c) as:

A = \epsilon lc----(1)

where ε = molar absorption coefficient

l = path length

A plot of 'A' vs 'c' gives a straight line with slope = εl

In addition absorbance (A) is related to % Transmittance (%T) as:

A = 2-log%T----(2)

For the FAS solution, the corresponding calibration fit is given as:

y = 3678(x) + 0.056

This implies that the slope = εl = 3678

It is given that %T = 25.6%

A = 2-log(25.6)=0.592

Based on equation(1):

c = \frac{A}{\epsilon l}=\frac{0.592}{3678}=1.61*10^{-4}M

olga nikolaevna [1]
<h3>Answer: Choice A)  0-7</h3>

Explanation:

If the pH is between 0 and 7, then we have an acid.

If the pH is between 7 and 14, then we have an alkaline base.

If pH = 7, then it's neutral.
