Answer:

116 °C

Explanation:

The given parameters of the Substance Q are;

The boiling point of Q = 445°

The substance <em>Q</em> is a solid at room temperature

Given that <em>Q</em> has a single fixed boiling point, <em>Q</em>, is suspected to be a pure substance, and it will therefore also have a fixed single melting point above room temperature;

Therefore, the best option is option C. 116 °C, which is above a single temperature value above 116 °C

What factors do you think should be considered in selecting a metal to use to reclaim copper? Which factor do you think is the m
Lana71 [14]

Answer:

Aluminum

Explanation:

<h3> <em>Aluminum would be the best choice to reuse  copper from the copper chloride solution because it  In the aluminum–copper reaction, the chloride ions help remove the aluminum oxide coating so that a reaction can take place through the oxidation of aluminum and the reduction of copper ions.The aluminum–copper chloride reaction is a simplified version of a waste reclamation and reduction strategy for handling toxic-waste materials. </em></h3>

What is the number of moles in 500L of He gas at STP
kompoz [17]
Ah, this is actually a fairly simple chemistry question.

Recall that at STP, one mole is equivalent to 22.4 L. Knowing this, all you have to do is divide 500 L by 22.4 L to find the number of moles:

500/22.4 = 22.3 mol

You have 8 moles of a gas at 250 K in a 6 L container. What is the pressure of the gas? Show your work
Bogdan [553]

Hello:

In this case, we will use the Clapeyron equation:

P = ?

n = 8 moles

T = 250 K

R = 0.082 atm.L/mol.K

V = 6 L

Therefore:

P * V = n *  R * T

P * 6 = 8 * 0.082* 250

P* 6 = 164

P = 164 / 6

P = 27.33 atm


Hope that helps!
