While molecules such as glucose move freely in the blood, triglycerides are carried in the blood by very low density lipoprotein

s (VLDLs) in the form of chylomicrons. A chylomicron resembles a droplet, with phospholipid heads and VLDLs facing water, the solvent of blood, while triglycerides are found within. The outer surface resembles that of a regular phospholipid bilayer. If the contents of a chylomicron are all lipids
A. then they should be soluble in blood plasma.
B. an inner layer is needed because phospholipids always form bilayers,
C. there is no need for an inner phospholipid layer in a chylomicron

Answer:

B. an inner layer is needed because phospholipids always form bilayers.

Explanation:

Lipids are organic compounds which are not soluble in water but they are soluble in organic compounds. They are formed in body by combination of various molecules. The inner layer of phospholipids always form bilayers.

According to the reaction below, how many grams of KCl (potassium chloride) can be formed from 70.90 g of chlorine with excess p
Pepsi [2]

Answer:

149.1 g KCl

Explanation:

2 K  +  Cl₂  ⇒  2 KCl

This is your chemical equation.  Use this equation to figure out the stoichiometry between Cl₂ and KCl.  According to the equation, for every 2 moles of KCl, you need 1 mole of Cl₂, making the ratio between KCl and Cl₂ 2/1.

First, convert grams of Cl₂ to moles of Cl₂.  The molar mass is 70.906 g/mol.

(70.90 g Cl₂)/(70.906 g/mol) = 0.9999 mol Cl₂

Convert moles of Cl₂ to moles of KCl using the stoichiometric relationship.

(0.9999 mol Cl₂) × (2 mol KCl/1 mol Cl₂) = 1.9998 mol KCl

Convert moles of KCl to grams of KCl.  The molar mass is 74.55 g/mol.

(1.998 mol KCl) × (74.55 g/mol KCl) = 149.1 g KCl

You will produce 149.1 g KCl.

True or false when heat is added to atoms the molecules vibrate much more slowly
Temka [501]

Answer:

false

Explanation:

The particles are held together too strongly to allow movement from place to place but the particles do vibrate about their position in the structure. With an increase in temperature, the particles gain kinetic energy and vibrate faster and more strongly
