Answer:

Hey!

The electromagnetic radiation the Earth recieves form the sun is a mixture of Infrared, Visible and Ultraviolet (UV)...

As these different wavelengths of Electromagnetic radiation approaches the Earth, these are absorbed by different parts of the atmosphere or reach the surface (where Humans are present)...

A layer of OZONE absorbs UV rays...

Visible light is of course not absorbed by the Atmosphere and reaches the surface of the Earth (This is what we see as daylight)

The layer of GREENHOUSE GASES (Carbon-Dioxide, Methane) absorbs and reflects the Infrared rays (aka HEAT) and sometime re-emitted back into space...

Explanation:

HOPE THIS HELPS!!

Al:ch2 an molar ratio.

2:3 and an x. X is 30.  20/2 = 10 so an answer is 

45/3 = 15. Both ratios are used 

45 - 30 = 15 CL2 left.

What pressure, in atmospheres, is exerted on the body of a diver if he is 38 ft below the surface of the water when atmospheric
Talja [164]

The pressure of diver = atmospheric pressure + water pressure

atmospheric pressure = 750 mmHg (as given) = 750 / 760 atm = 0.987 atm

Water pressure is

P = hρg

where

h = height of water = 38 ft

1 ft = 0.3048

38 ft = 11.58 m

ρ = density  = 1000 Kg / m³

g = gravitational constant  = 9.81 m/s2

P = 11.58 X 1000 X 9.81 = 113599.8 Kg / m s^2 Or N /m^2

1 N / m^2 = 1 pa = 9.869 X 10^-6 atm

P = 113599.8 Pa = 1.12 atm

Total pressure = 1.12 + 0.987 atm = 2.107 atm = 2.1 atm (two significant figures)

2 questions, please help!!
Amanda [17]

i'd go for universal indicator, bromothymol blue and methyl red  

i mean, they have the degrees of acidity (specific color changes)  

they have wider ranges of color changes which will lead to the strength of acid  

you will know the degree of acidity of the cosmetics  

in fact, bromothymol blue is used to detect the slightest level of acid or base in a substance  

universal indicator has the pH charts; the range is big so that you can measure the level of acidity effectively  

methyl red is sensitive too as the other two mentioned earlier  

the other way that's not included in your choices is the pH meter  

unlike litmus papers which just have 2 results; either red or blue  

phenolphthalein only colorless, pale pink  

you won't know the degree of acidity  

hope that helps
