Determine whether a closed spiral notebook with no writing would be chiral or achiral.

1 answer:

4 0

A chiral<span> object is one that is not superimposable on its mirror image. Conversely, an achiral object is one that is identical (superimposable) to its mirror image. I believe a closed spiral notebook is a chiral object. Hope this answers the question. Have a nice day.</span>

Not very much because half the time the water is purified but just normal water in my area probably has serious levels of scarcity.

You have 55 grams of glucose(C6H12O6). How many grams of oxygen do you have?

zubka84 [21]

Answer:

Mass of oxygen in glucose = 29.3g

Explanation:

Mass of glucose given is 55grams.

We are to find the mass of oxygen in this compound.

In the compound we have 6 atoms of oxygen.

Solution

To find the mass of oxygen in glucose, we calculate the formula mass of glucose. We now divide the formula mass of the oxygen atom with that of the glucose and multiply by the given mass to find the unkown mass.

Atomic mass of C = 12g

H = 1g

O = 16g

Formula mass of C₆H₁₂O₆ = {(12x6) + (1x12) + (16x6)} = 180

Mass of O in glucose = $\frac{6x16}{180}$ x 55

= $\frac{96}{180}$ x 55

= 0.53 x 55

Mass of oxygen in glucose = 29.3g

Identify all the physical properties of a base.

KiRa [710]

Answer:

Bases are ionic compounds that produce negative hydrogen ions (OH⁻) when dissolved in water.
An example of a base is Sodium Hydroxide (NaOH).
Bases have a bitter taste.
Bases feel slippery.
Bases conduct electricity when dissolved in water.
Bases change litmus paper from red to blue in colour.
They react with acids to form a salt and water, this process is called neutralisation.
The pH of bases ranges from 8-14.
Turns phenolphthalein pink.

Hope this helps!

Amanda [17]

Answer:

The answer is explained below

Explanation:

Put the steps of the carbon cycle in order using Step 1 as your starting point

Step 1: Bacteria, through nitrogen fixation and nitrification, convert nitrogen into a usable form. The animal dies and decomposes, returning nitrogen back to the soil. Once nitrogen is in usable form, it is taken up by plants and assimilated into proteins.. An animal eats a plant and the nitrogen becomes part of the animal’s proteins.

The steps taking in the carbon circle using step 1 as the starting point is as follows:

Step 1: Bacteria, through nitrogen fixation and nitrification, convert nitrogen into a usable form.

Bacteria convert nitrogen into nitrites and nitrates through the process of nitrification. Nitrites and nitrates are in the form that can be used by the plants

Step 2: Once nitrogen is in usable form, it is taken up by plants and assimilated into proteins.

The Nitrogen can only be used by the plants when in nitrites and nitrates form. When in this form, it is then assimilated into plant tissue as protein.

Step 3: An animal eats a plant and the nitrogen becomes part of the animal’s proteins.

An animal such as rabbit eats the plant and the protein in the plant becomes protein in the animal.

Step 4: The animal dies and decomposes, returning nitrogen back to the soil.

When the animal dies, the animal undergoes decomposition and the nitrogen in the animal is returned to the soil
