B. At room temperature, fats are solid and oils are liquid.

C. Fats are lipids and oils are carbohydrates.

D. Fats are triglycerides and oils are waxes.

Answers

Answer 1
Answer:

Answer:

B. At room temperature, fats are solid and oils are liquid.

Explanation:

Fats and oils are one of the the three macronutrients (the other two are protein and carbohydrates).

However, fats and oils are different from each other: fats are mainly obtained from animals, while oils are mainly obtained from vegetable sources.

The major difference between fats and oil is that fats are composed of high amounts of saturated fatty acids which makes them solid at room temperature, while oils are composed of mainly unsaturated fatty acids which makes them liquid at room temperature.

Note that: in daily use the two terms may be used interchangeably.
Answer 2
Answer:

It is B.  When at room temperature fats are solid and oils are liquids.

How many liters of O2 gas will be produced at STP from 4 moles of KC1O3

Answers

Answer:

V = 134.5 L

Explanation:

Given data:

Number of moles of KClO₃ = 4 mol

Litters of oxygen produced at STP = ?

Solution:

Chemical equation:

2KClO₃  →  2KCl   + 3O₂

Now we will compare the moles of KClO₃ with oxygen.

                    KClO₃        :           O₂

                        2            :           3

                        4            ;          3/2×4 = 6 mol

Litters of oxygen at STP:

PV = nRT

V = nRT/P

V = 6 mol × 0.0821 atm.L/mol.K × 273 K / 1atm

V = 134.5 L / 1

V = 134.5 L

You and your friend live in different states and plant identical hydrangea bulbs in your garden. When they bloom, you send each other pictures. You notice that even though you bought the exact same kind of plant, your hydrangea flowers are blue and your friend’s are pink! On a hunch, you each measure the pH of your soil and find that your soil is a little acidic and your friend’s is a little basic. Why do you think the flowers have different colors?

Answers

Since the hydrangeas are changing color depending on whether the soil is acidic or basic, they must have an indicator. This means that any hydrangea planted in acidic soil will have blue flowers and any hydrangea planted in basic soil will have pink. One common indicator present in many plants is anthocyanin, so maybe hydrangeas contain that chemical.

I think the soil has a lot to do with the reason why the flowers have different colors.

Soil

A soil is a mixture of organic matter that supports life. There are 4 types of soil which are sand, silt., clay and loam soil.

A hydrangea flower is affected by the acidity of the soil to influence the color it turns out to be.

The acidic property in the soil used to plant the flower turned it blue,

while The alkaline property in the soil turned the color pink.
