Answer:
The concentration of green house gases must be appropriate in order to maintain an optimum temperature on the earth.
More the concentration of gases on earth, the temperature would increase because the green house gases more heat in it.
If the overall green house gas will decrease then also the temperature on the earth will not be adequate for living as it will be too cold.
hence, the balance is maintained only when there is a proper concentration of carbon dioxide in atmosphere.
There are two types of mixture depending on the distribution of the components in the mixture. Homogeneous mixtures are mixtures which has uniform properties all throughout the solution while heterogeneous mixtures are the opposite they do not exhibit uniformity in any property. Example for a homogeneous is a salt solution where at any point you get a sample the properties are the same. For the heterogeneous mixture, a mixture of sand and salt where at any sampling point the properties are not the same.
a suspension
the particles are big enough to settle
a colloid
the particles are too small to ever settle
a solution
homogeneous mixture of two or more substances
(2) They are Arrhenius acids and they turn red litmus blue.
(3) They are Arrhenius bases and they turn blue litmus red.
(4) They are Arrhenius bases and they turn red litmus blue.
Answer:The correct answer is option (1).
Explanation:
Arrehinius acid are those which gives hydronium ion when dissolved in water.
Arrehinius base are those which gives hydroxide ion when dissolved in water.
Both nitric acid and acetic acid are Arrhenius acids.And they turn the color of blue litmus paper to red color.
Hence, the correct answer is option (1).
