Answer:

This statement is true.

Explanation:

Conserving water means using our water supply wisely and being responsible.

Although 71% of the Earth is covered by water, ninety-seven percent of it is salt water, which is not suitable for drinking. In addition, only 3% of the water on Earth is fresh water, and only 0.5% is available for drinking. The rest of the fresh water is enclosed in ice sheets, glaciers, the atmosphere, the ground or below the surface of the earth, or is too contaminated for consumption. That's why water care and conservation is important.

In addition to being a limited resource, all species on this planet need water to live and survive. And without water, aquatic life will have no chance of survival. Therefore, water saving is essential, essential for our sustainability.

One of the benefits of water conservation is that it helps preserve our environment. The reduction of water use reduces the energy needed to process it and deliver it to homes, businesses, farms and communities. In turn, this helps reduce pollution and conserve fuel resources. Water pumping from the central installation requires large amounts of energy to operate the equipment. So, saving water will also lead to saving energy. Finally, saving water and energy consumption allows companies to charge the user less. This generates a saving of money.

So, water conservation can save money and protect the environment. The statement given is true.

Answer: The given statement is true.

Explanation:

Water is a natural resource present in the nature and it is very precious as life without it is impossible.

So, when we unnecessarily use water then it means we are wasting a natural resource that cannot be reproduced again by human beings.

Therefore, more we are able to conserve water more we can protect other human life's and environment also.

If there is shortage of water then its prices will go high and hence we need to pay more for it.

Thus, we can conclude that the statement conserving water can save money while protecting the environment, is true.

Calculate the volume in cm^3 of 325.0 dg of alcohol. Alcohol has a density of 0.785g/mL.

Masteriza [31]

Answer:
106 mL

Explanation:
In order to be able to answer this question, you must understand what the density of a substance tells you.
The density of a substance is nothing more than the mass of that substance that occupies one unit of volume.
In your case, the density of ethanol is given in Grams per milliliter, which means that one unit of volume will be
1 mL
.
So, ethanol has a density of
0.785 g mL
−
1
, which is equivalent to saying that if you take exactly
1 mL
of ethanol and weigh it, you will end up with a mass of
0.785 g
.
Now, you know that the volume you're using has a mass of
83.3 g
. Well, if you get
0.785 g
for every
1 mL
of ethanol, it follows that this much mass will correspond to a volume of
83.3
g ethanol
⋅
ethanol's density

=
106.11 mL
Rounded to three sig figs, the answer will be

ethanol
=
106 mL

A student made the Lewis dot diagram of a compound as shown. Mg is written with two dots shown on its top. Cl is written on the

blsea [12.9K]

Answer:

The dots were not properly located and arrows are not used in Lewis structures

Explanation:

If we intend to write a Lewis structure for a compound, that lewis structure must consist of only dots. These dots actually show the valence electrons on the outermost shell of the molecule.

We do not involve arrows when writing dot electron structures for compounds. The valence electrons of magnesium ought not to be written together because they are not a lone pair, rather they are two unpaired electrons. The use of an arrow suggests a coordinate covalent bond which is not the case here.

The correct lewis structure for MgCl2 is shown in the image attached to this answer.

Please help meeee, I will brainliest. and Put it into your own words, if u use from internet.

Step2247 [10]

Answer:

energy is used to break bonds in reactants and energy is released when new bonds form in products.The law of conservation of energy states that matter cannot be created or destroyed. Whether a chemical reaction absorbs or releases energy there is no overall change in the amount of energy during the reaction.
