Which part or parts of the paragraph indicate the relationship between public support and the enforcement of environmental polic

ies?
A new manufacturing company was the brainchild of five engineers. They created a device that controls a company’s carbon footprints. To spread awareness for their own benefit, they proposed a legislative bill related to tracking and controlling carbon footprints. They constantly followed up with congressional representatives and found a sponsor and several co-sponsors for the bill.

A 31.25 mL aliquot of weak base that has a concentration of 0.683 M will be titrated with 0.434 M HCl. Calculate the pH of of th
Pavel [41]

Answer:

pH = 8.18

Explanation:

The weak base, X, reacts with HCl as follows:

X + HCl → HX⁺ + Cl⁻

<em>Where 1 mole of X with 1 mole of HCl produce 1 mole of HX⁺ (The conjugate acid of the weak base).</em>

Now, using H-H equation for bases:

pOH = pKb + log [XH⁺] / [X]

<em>Where pOH is the pOH of the buffer (pH = 14 -pOH)</em>

<em>pKb is -log Kb = 5.824</em>

<em>And [X] [HX⁺] are the molar concentrations of each specie</em>

Now, at the neutralization of the half of HX⁺, the other half is as X, that means:

[X] = [HX⁺]

And:

pOH = pKb + log [HX⁺] / [X]

pOH = 5.824 + log 1

pOH = 5.824

pH = 14-pOH

<h3>pH = 8.18</h3>

Explain why copper 2 oxide is a base although it does not turn litmus paper to blue​
In-s [12.5K]

Answer:

See explanation

Explanation:

Copper II oxide is a base but not an alkali. An alkali is a soluble base. Since Copper II oxide is not soluble in water then it is not an alkali.

Let us recall that the change of colour of litmus with an alkali requires the presence of water. In the absence of water, solid Copper II oxide does not turn red litmus paper blue.

The ability to turn red litmus paper blue is commonly observed with alkalis and Copper II oxide is not an alkali.

Also recall that since Copper II oxide is not soluble, hydroxide ions are absent hence Copper II oxide does not turn red litmus paper blue.
