How do clouds relate to climate change
Vedmedyk [2.9K]

Answer:

Clouds can block light and heat from the Sun, making Earth's temperature cooler. You've probably noticed this kind of cooldown on a cloudy day. However, some heat from the Sun does get down to Earth. Clouds can trap that heat from the Sun.

Hope that helps :)

Answer:

1 atom of carbon on the reactant side (CH₄ is methane, 1 carbon, 4 hydrogen).

1 atom of carbon on product side (Law of Conservation of energy proves this).

4 hydrogen on reactant side (CH₄ is methane, 1 carbon, 4 hydrogen).

4 hydrogen on product side (Again, the Law of Conservation of energy proves this)

4 oxygen atom on the reactant side (2O₂ means two diatomic molecules, or two oxygen molecules of 2 atoms each).

4 oxygen atoms on the product side (Law of Conservation of energy).

2 molecules of oxygen on the reactant side.

2 molecules of water on the product side

Yes, the chemical equation is balanced. The amount of atoms is the constant on both the reactant and product side.

A Ionic bond is chemical bond between two oppositely charged ions because of the transfer of valence electrons between them.

A covalent bond is a chemical bond in which two or more atoms share electrons between them. They can also form polar covalent bond or non-polar covalent bonds (Although that depends on the electronegativities of the atom).

The bond of a carbon dioxide molecule is covalent bond (Polar covalent bond if you've learned that yet)

Potassium Fluoride (KFl) form an ionic bond.

2Al₂O₃ --> 4Al + 3O₂

A reducing agent loses electrons while and oxidizing agent gains electrons.

In an endothermic reaction, the total bond energy in the reactants is greater than the bond energy of products so energy is absorbed by the reaction. (For an endothermic reaction, more energy needs to be absorbed than released).

Tris {(hoch2)3cnh2} is one of the most common buffers used in biochemistry. a solution is prepared by adding enough tris and 12
shusha [124]

Given that,

The concentration of TRIS = 0.30 M

The concentration of TRIS+ = 0.60 M

Kb = 1.2 x 10^-6

pKb = -log Kb = - log (1.2 x 10^-6) = 5.920

Now, by using the Hendersonn equation,

pH = pKa + log TRIS+/TRIS = 5.920 + log (0.60/0.30) = 6.221

<span>pOH=14-pH=14-6.221 = 7.779</span>
