Hello i need help please Questions 1 and 2 (lipids)

Chemistry

dlinn [17]1 year ago

The question requires us to complete the sentences regarding characteristics and properties of lipids.

First, we need to keep in mind what are lipids: these essential molecules to cell's membranes are typically made of a glycerol backbone, fatty acid "tails" (the hydrofobic part) and and a phosphate group (a hydrophilic part). The term "lipids" is commonly used as a synonym for "fats", which it isn't completely wrong as they share many properties (for example, lipids don't mix with water).

As they are organic molecules, all lipids have carbon, oxygen and hydrogen in their structure, while some of them can contain other elements (such as phosphorus for the phospate group and nitrogen).

<em>Considering the information above, we can complete the sentences as:</em>

<em>1. "Lipids is a general term describing organic molecules that are </em>insoluble<em> in water".</em>

<em>2. "</em>All<em> lipids are made of carbon, hydrogen and oxygen, while </em>some<em> lipids contain other elements..."</em>

<h3>A Werewolf</h3>

___________

Poem with Compound Words

------------------------------------------

whenever there's a full moon,

I cannot overlook,

some alterations in my ways,

and changes in my look.

my werewolf hair grows everywhere,

my werewolf teeth get long,

my eyesight gets much keener and

I'm muscular and strong.

I get to roam around outside,

the moonlight makes me howl,

these otherworldly sound effects

mean I am on the prawl.

I see the moon is round and full,

I'm moonstruck by the sight,

I've made some telltale changes-so, you'd best stay in tonight.

Dolomite, [CaMg(CO3)2] is found in a soil sample. A geochemist titrates 24.65 g of soil with 57.85 mL of 0.3315M HCl. What is th
pshichka [43]

In order to find out the %mass dolomite in the soil, calculate for the mass of dolomite using the information given from the titration procedure. You would need to multiply 57.85 ml with 0.3315 M HCl and you would get the amount of HCl in millimoles. Then multiply the amount of HCl with 1/2 (given that for every 1 mol of dolomite, 2 mol of HCl would be needed). Convert the amount of dolomite to mass by multiplying the millimoles with the molecular weight which is 184.399. Then convert the mass to grams which is 1.768 grams. Divide the mass of dolomite (1.768 grams) with the weight of soil sample. The % mass is 7.17.
