Answer:

Option (A)

Explanation:

The resources that can be regenerated again over a specific period of time are known as renewable resources. For example, Wind, Water, and Sunlight.

Water is one of the most necessary and valuable renewable resources. It is considered to be renewable because it can be obtained again and again by undergoing certain processes that form a cycle which is commonly known as the water cycle.

In the water cycle, the water moves from the surface to the atmosphere in the form of vapor by undergoing the process of evaporation and transpiration and comes back to the surface in the form of rainfall, by undergoing the process of condensation.

This is how water changes its phase from one type to another, recycling within the system, thereby regenerating it. So, water is usually classified as a renewable resource.

Thus, the correct answer is option (A).

Write down examples of some natural acids and natural bases. Also write use of them.

trasher [3.6K]

Answer:

Formic acid, citric acid, Oxalic acid, washing soda, baking soda, etc. can be some examples of natural acids and natural bases. They both have domestic, industrial, and various other purposes.

Explanation:

<h3><u>NATURAL ACIDS</u>:</h3>

There are lots of natural acids present in our nature. Some of them are the following:

> <u>Formic acid</u>

USE: It is used in the stimulation of oil and gas wells as it is less reactive towards the metal.

> <u>Citric acid</u>

USE: It is considered as the best rust remover as it doesn't harm the metal just remove the rust.

> <u>Oxalic acid</u>

USE: It easily remove iron and ink stains and that's why it is used as an acid rinsing material in Laundries.

<h3><u>NATURAL BASES</u>:</h3>

There is a variety of natural base found in our nature which founds a lot of uses in day to day life. some of them are the following:

> <u>Washing soda</u>

USE: It is used in commercial detergent mixture to treat hard water.

> <u>Baking soda</u>

USE: It is the best rising agent used mostly in cooking and for domestic purposes like removing stains, etc..

Magnesium has three naturally occurring isotopes with masses of 23.99 amu, 24.99 amu, and 25.98 amu and natural abundances of 78

mihalych1998 [28]

Answer:24.31

Explanation:Contribution made by isotope of mass 23.99= 23.99×78.99=1894.97

Contribution made by isotope of mass 24.99=24.99×10.00=249.9

Contribution made by isotope of mass 25.98=25.98×11.01=286.04

Total contribution=1894.97+249.9+286.04=2430.91

Average mass=2430.91÷100

=24.31

calculate the mass of butane needed to produce 64.1 g of carbon dioxide to three significant figures and appropriate units

cricket20 [7]

Answer:

21.2 gm

Explanation:

calculate the mass of butane needed to produce 64.1 g of carbon dioxide to three significant figures and appropriate units

butane is the hydrocarbon C4H10

in combustion, we react hydrocarbons with O2 to form CO2 and H2O

C4H10 + O2----------------> CO2 + H2O

BALANCE

2C4H10 + 1302--------> 8CO2 + 10 H2O

the molar mass of CO2 is 12 + 16X2 = 44

64.1 gm of CO2 is

64.1/44 = 1.46 MOLES OF CO2,

FOR EVERY 8 MOLES OF CO2 WE NEED 2 MOLES OF BUTANE IT IS A

8:2 OR 4:1 RATIO. THE MOLES OF C4H10 ARE 1/4 THE MOLES OF CO2

THE MOLES OF C4H10 H10 ARE 1.46/4 =0.365 MOLES

THE MOLAR MASS OF BUTANE IS 58.12

0.365 MOLES OF C4H10 HAS A MASS OF 0.365 X 58.12 = 21.2 gm
