Answer:
Protein Concentration is 2.82mg/L
Explanation:
According to Beer-Lambert's Law, Absorbance is directly proportional to the concentration.
However, the concentration of a solution can be determined from a calibration curve, in which Absorbance is plotted on the y-axis and the Concentration on the x-axis.
Plotting the best line, the equation of line is used
y = mx + c
where y is absorbance = 0.150
m is slope = 0.0163
x is concentration
c is intercept = 0.104
inserting the values from the question
y = mx + c
0.150 = 0.0163x + 0.104
0.0163x = 0.150 - 0.104
0.0163x = 0.046
Divide both sides by 0.0163
0.0163x/0.0163 = 0.046/0.0163
x = 2.82
Concentration of protein = 2.82 mg/L
Answer:
A crystal or crystalline solid is a solid material whose constituents (such as atoms, molecules, or ions) are arranged in a highly ordered microscopic structure, forming a crystal lattice that extends in all directions. The scientific study of crystals and crystal formation is known as crystallography.
Explanation:
A chemical change is one where the compounds are modified: a compound decomposes into its elements, or combine with other elements to form a different compound.
That is what happens when a match burns: oxygen reacts with the match compounds and form CO2(g), H2O(g) and other compounds depending on the composition of the match.
The other processes only involve a physical change of the compounds, but they remain being the same compounds (same elements with the same bonds).
Answser: option 1. the burning of a match.
Answer:
The Earth's magnetic field intensity is roughly between 25,000 - 65,000 north magnetic pole is 86.50°N and 164.04°E and the south magnetic pole is 64.07°S and 135.88°E
The circle at the very top is magma, when it cools and hardens it becomes igneous rock. Weathering and erosion leads to the circle which is sediment, which through compaction becomes sedimentary rock. And when heat and pressure is applied, it becomes metamorphic rock, which can melt to be magma
