Answer:

The answer to your question is below

Explanation:

Data

Demonstrate pH = -0.301

concentration = 2 moles/L

Formula

pH = -log [H⁺]

Process

1.- Calculate the [H⁺] concentration

[H⁺] = 2 moles/L = 2 M2.- Substitute in the formula

pH = -log[2]

simplification

pH = -0.301

2.- Conclusion

It is an acidic solution

Differentiate between <br>Halogens and insert gases​
jasenka [17]

Answer:

An inert gas is one that does not undergo chemical reactions

Noble gases refers to the right most group of the periodic table composed of helium, neon, argon, krypton, xenon, and radon. As you might have seen as an example in class, some noble gases can form chemical compounds, such as XeF4.

or to say:

Halogens and noble gases are two different groups of elements that can be seen on the periodic table. Halogens are found in group 17 and include fluorine, chlorine, bromine, iodine and astatine. Noble gases make up group 18, and include helium, neon, argon, krypton, xenon and radon.

Upon heating a copper sample will expand, leading to a lower density? <br><br>A) True<br>B) False
Leona [35]

Answer;

The above statement is true

upon heating a copper sample will expand, leading to a lower density

Explanation;

-The density of solids decreased with increase in temperature and vice versa. The increase in temperature causes the volume of the solid to increase which as a result decreases the density as Density=Mass/Volume. The temperature of a body is the average kinetic energy of the molecules present in it.

In other words; The temperature of a body is the average kinetic energy of the molecules present in it. Therefore; when heat is supplied ( or temperature is increased) the average kinetic energy increases which increases the volume and thus density decreases.

titration 25.0 ml of 3.4 x 10^ -3 M of Ba(OH) Neutralize 16.6 mL of HCL solution. What is the molarity of HCL solution?
marusya05 [52]
What we  are give: Concentration of base (CB) = 3.4 × 10^{-3}
Then convert all volume in ml to L.
Volume of base (VB) 25.0ml = 0.025L
Volume of acid (VA) 16.6ml = 0.0166L
Now that we have everything we use the formula CAVA=CBVB.
Make 'CA' the subject then solve. 
CA=\frac{CBVB}{VA}
