Answer: Copper is being reduced

Explanation:

Paraphin [41]4 years ago
7 0

<u>Answer:</u> The correct answer is copper is getting reduced.

<u>Explanation:</u>

Oxidation reaction is defined as the reaction in which an atom looses its electrons. Here, oxidation state of the atom increases. These reaction are shown by reducing agents.

X\rightarrow X^{n+}+ne^-

Reduction reaction is defined as the reaction in which an atom gains electrons. Here, the oxidation state of the atom decreases. These reactions are shown by oxidizing agents.

X^{n+}+ne^-\rightarrow X

For the given chemical reaction:

Cu^{2+}(aq.)+2e^-\rightarrow Cu(s)

Here, copper atom is gaining 2 electrons to form copper metal. Thus, it is undergoing reduction reaction and is getting reduced.

Calculate the average net charge on phenylalanine if it is in a solution that has a ph of 8.70.
Alex Ar [27]
Phenylalanine has two known pKa charges: 1.83 and 9.13. To determine their individual ionic dissociation charges at pH 10, the equation to be used is

pH = pKa + log [α/(1-α)]

At pKa 1.83:
10 = 1.83 + log [α₁/(1-α₁)]
α₁ = 0.99999

At pKa 9.13:
10 = 9.13 + log [α₂/(1-α₂)]
α₂ = 0.88114

Average Net Charge =  0.99999 + 0.88114 = 1.88

At a given temperature, 4.06 atm of H2 and 3.5 atm of Cl2 are mixed and allowed to come to equilibrium. The equilibrium pressure
Llana [10]

<u>Answer:</u> The value of K_p for the given chemical reaction is 0.1415

<u>Explanation:</u>

Equilibrium constant in terms of partial pressure is defined as the ratio of partial pressures of the products and the reactants each raised to the power their stoichiometric ratios. It is expressed as K_p

For a general chemical reaction:

aA+bB\rightarrow cC+dD

The expression for K_p is written as:

K_p=\frac{p_{C}^cp_{D}^d}{p_{A}^ap_{B}^b}

For the given chemical equation:

H_2(g)+Cl_2(g)\rightleftharpoons 2HCl(g)

The expression for K_p for the following equation is:

K_p=\frac{(p_{HCl})^2}{(p_{H_2)}(p_{Cl_2})}

We are given:

p_{HCl}=1.418atm\\p_{H_2}=4.06atm\\p_{Cl_2}=3.5atm

Putting values in above equation, we get:

K_p=\frac{(1.418)^2}{(4.06)\times (3.5)}\\\\K_p=0.1415

The value of K_p for the given chemical reaction is 0.1415

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 :)
