(a) The absorbance of mixture at 400 nm was 0.40.
laiz [17]

Answer:

0.1 g/dl

Explanation:

The standard curve is a graph that relates the absorbance at 400 nm with the concentration of haemoglobin in mg/dl. To obtain the concentration from the absorbance value, we enter in the x-axis (absorbance at 400 nm) with the value 0.40 (the line between 0.2 and 0.6), we extrapolate the line to the curve and read the correspondent value on y-axis (concentration in mg/dl): 100 mg/dl.

So, we convert the concentration from mg/dl to g/dl by dividing into 1000:

100 mg/dl x 1 g/1000 mg = 0.1 g/dl

Therefore, the concentration of haemoglobin of the patient is 0.1 g/dl.

In a chemical process, you need to force a compound to bond with a halogen, causing it to lose hydrogen. Which type of reaction
Kazeer [188]
Answer is Halogenation because Halogenation is a type of substitution reaction in which a hydrogen atom is replaced by a halogen atom in a molecule.
The molecule looses its hydrogen atom as the halogen is introduced into the molecule. This sort of reaction is very common in organic chemistry. Many hydrocarbons can be halogenated in the presence of light.

Which of these best describes the relationship between the inner core, outer core, mantle, crust, asthenosphere, and lithosphere
torisob [31]

The question is incomplete, the complete question is;

Which of these best describes the relationship between the inner core, outer core, mantle, crust, asthenosphere, and lithosphere?

A: The coolest layers are farthest from the core.

B: The least dense layers are closest to the core.

C: The layers with the highest concentration of metals are closest to the crust.

D: The layers that remain in a molten state are closest to the crust.

Answer:

The coolest layers are farthest from the core.

Explanation:

When we talk about the internal structure of Earth, we mean the subdivisions of the solid Earth, that is, the concentric spherical layers that marks out the structure of the solid Earth.

The inner core is the innermost part of the earth's core and is known to have extremely high temperature. This high temperature steadily decreases as you approach the earth's surface.

Hence, the coolest layers are farthest from the core.
