Properties: The melting point of phosphorus (white) is 44.1°C, boiling point (white) is 280°C, specific gravity (white) is 1.82, (red) 2.20, (black) 2.25-2.69, with a valence of 3 or 5. There are four allotropic forms of phosphorus: two forms of white (or yellow), red, and black (or violet).Oct 7, 2019

Explanation:
Chylomicron is a small fat globule which is made of protein and lipids. These substances are found in the lymphatic fluid and blood where they tend to transport fat from the entry in the intestine to the liver and adipose tissue.
Once, one eats the fatty meal the blood is full of a number of chylomicrons which provides the blood texture.
The food that is digested is absorbed and transported to various parts of the body.
Answer: 9.27 g of Na
Explanation:Please see attachment for explanation
Answer is: 4,4 grams <span>of carbon dioxide gas would be produced.
</span>Chemical reaction: CaCO₃ + 2HCl → CaCl₂ + CO₂ + H₂O.
m(CaCO₃) = 10 g.
n(CaCO₃) = 10 g ÷ 100 g/mol.
n(CaCO₃) = 0,1 mol.
From chemical reaction: n(CaCO₃) : n(CO₂) = 1 : 1.
n(CO₂) = 0,1 mol.
m(CO₂) = n(CO₂) · M(CO₂).
m(CO₂) = 0,1 mol· 44 g/mol.
m(CO₂) = 4,4 g.
