Explain how scientific theory differ from scientific law

2 answers:

8 0

Scientific law predicts the results of certain initial conditions. It might predict your unborn child’s possible hair colors, or how far a baseball travels when launched at a certain angle.
In contrast, a theory tries to provide the most logical explanation about why things happen as they do. A theory might invoke dominant and recessive genes to explain how brown-haired parents ended up with a red-headed child, or use gravity to shed light on the parabolic trajectory of a baseball.

What is the function of lipoprotein lipase?

scZoUnD [109]

Answer:

Hydrolysis of triglycerides in lipoproteins

Explanation:

Lipoprotein lipase is a water-soluble enzyme which includes pancreatic lipase, hepatic lipase, and endothelial lipase.

Enzymes involved in triacylglycerol digestion are lipases and they catalyze the partial hydrolysis of triglycerides into a mixture of free fatty acids and acylglycerols. After digestion of lipids, monoglycerides and fatty acids associate with bile salts and phopholipids to form micelles. Micelles are structures that are necessary for the transport the poorly soluble monoglycerides and fatty acids to the surface of the enterocyte. But, micelles cannot be absorbed by epithelial cell, only freely dissolved monoglycerides and fatty acids can.

How many grams of the compound in the figure above are required to make 1 liter of a 0.5 M solution? (Note: The atomic masses, i

Dafna1 [17]

Answer:

This question is incomplete as there is no figure in the question but the compound in the figure is Ethanoic acid (CH3COOH). Hence, we can calculate the mass.

The answer is: 30grams

Explanation:

According to the question, the volume of the compound (CH3COOH) is 1litre while the molar concentration is 0.5M

Molarity or Molar concentration is calculated using the formula:

M= n/V

Where; M= Molarity (M) = 0.5M

n= number of moles (mol)

V= Volume (V) = 1L

Hence, number of moles (n) = M × V

n = 0.5 × 1

n = 0.5 moles.

To calculate the mass in grams of CH3COOH, we say;

Number of moles (n) × molar mass (MM)

Since atomic mass for (C= 12, H= 1 and O=16)

Molar mass of CH3COOH:

= 12 + 1(3) + 12 + 16 + 16 + 1

Molar mass of CH3COOH = 60g/mol

Mass (in grams) of CH3COOH = 0.5 moles × 60g/mol

Mass = 30grams.

Therefore, 30grams of CH3COOH compound are required to make 1 liter of a 0.5 M solution.
