Carbon dioxide is the atmospheric compound that is
responsible (after it have dissolved in water) for both the general acidity of
normal rainwater and the acidity of much soil. Natural rain water is slightly
acidic because carbon dioxide combined with water in the air forms carbonic
acid, which is a weak acid.
Expanding in powers 4FCsixteen.
<h3>What is hexadecimal system?</h3>
Hexadecimal is an easy route for addressing twofold. It is vital to take note of that PCs don't utilize hexadecimal - it is utilized by people to abbreviate parallel to an all the more effectively reasonable structure. Hexadecimal Number System is generally utilized in Computer programming and Microprocessors. It is likewise useful to portray colors on pages. Every one of the three essential tones is addressed by two hexadecimal digits to make 255 potential qualities, hence bringing about in excess of 16 million potential tones. The primary benefit of utilizing Hexadecimal numbers is that it utilizes less memory to store more numbers, for instance it stores 256 numbers in two digits while decimal number stores 100 numbers in two digits. This number framework is likewise used to address Computer memory addresses.

Answer: For a given mass and volume, how much physical space a material takes up, of an object or substance, the density remains constant at a given temperature and pressure. The equation for this relationship is ρ = m / V in which ρ (rho) is density, m is mass and V is volume, making the density unit kg/m3.
Explanation: Hope that helps
I believe the answer is C
Answer:
Q_d=35881 J/mol
So the activation energy is 35881 J/mol.
Explanation:
Consider the following equations:
Solving the above two equation to find the Q_d in term of diffusivity and temperature we will get:
where:
Q_d is the activation energy
D_1 is the diffusivity at T_1
D_2 is the diffusivity at T_2
Q_d=35881 J/mol
So the activation energy is 35881 J/mol.
