Answer: Option (C) is the correct answer.

Explanation:

Clouds are basically condensed vapors and they can be formed at different altitudes and height.

For example, typically clouds appear between 6,500 feet to 20,000 feet.

Whereas when tiny droplets are suspended into the atmosphere then it is known as fog. And fog, generally appears at lower altitude than clouds.

Therefore, we can conclude that compared with clouds, fogs are at lower altitudes.

sergiy2304 [10]

Yes , I agree with the statement water contains minerals

<u>Explanation:</u>

When LaShawna saw the steam, she said that the water must contain a lot of minerals and the statement is true.
Most of the water comes from the underground supply and they undergo some cleaning process and stuff.
Usually, mineral water comes from natural underground water supply and the springs.
Chemical compounds like Calcium, potassium, sodium, iron are present in water.
Magnesium plays an essential function in maintaining blood supply and high mineral content water helps us to prevent or lower the heart-related disease.
Calcium is the building block for maintaining the bone's health.

one side of a cube measures 0.53 cm. the mass of the cube is 0.92 g. what is the density of the cube

ziro4ka [17]

Answer:

6.17 g/cm³

Explanation:

Data given:

one side of cube = 0.53 cm

mass of the cube is 0.92 g

density of the cube = ?

Solution:

First we will calculate for volume the cube

As we know all the sides or edges of a cube are equal so volume equation will be

So,

V = length x width x height

V = e³

as on side = 0.53 cm

then

V = (0.53 cm)³

V = 0.149 cm³

Now we will calculate density of cube

To calculate density, formula will be used

d = m/v . . . . . (1)

where

d = density

m = mass

v = volume

put values in above formula 1

d = 0.92 g / 0.149 cm³

d = 6.17 g/cm³

so. the density of cube = 6.17 g/cm³

Why do we need to standardize EDTA in determination of water hardness?

bonufazy [111]

Standardized means that a specific amount EDTA is added to a specific volume of distilled water. Water hardness is determined by the the amount of a standard EDTA solution to change the color of the water from red to blue. For example if one added the correct amount of EDTA to twice the volume of distilled water the solution would be weak. Titration of the hard water would give a erroneous high result.

Which of these half-reactions represents reduction?

gogolik [260]

Answer: The half-reactions represents reduction are as follows.

$Cr_{2}O^{2-}_{7} \rightarrow Cr^{3+}$
$MnO^{-}_{4} \rightarrow Mn^{2+}$

Explanation:

A half-reaction where addition of electrons take place or a reaction where decrease in oxidation state of an element takes place is called reduction-half reaction.

For example, the oxidation state of Cr in $Cr_{2}O^{2-}_{7}$ is +6 which is getting converted into +3, that is, decrease in oxidation state is taking place as follows.

$Cr_{2}O^{2-}_{7} + 3 e^{-} \rightarrow Cr^{3+}$

Similarly, oxidation state of Mn in $MnO^{-}_{4}$ is +7 which is getting converted into +2, that is, decrease in oxidation state is taking place as follows.

$MnO^{2-}_{4} + 5 e^{-} \rightarrow Mn^{2+}$

Thus, we can conclude that half-reactions represents reduction are as follows.

$Cr_{2}O^{2-}_{7} \rightarrow Cr^{3+}$
$MnO^{-}_{4} \rightarrow Mn^{2+}$
