Yes, Sharpies contain volatile solvents—and when inhaled these solvents can produce a "high." The effects of inhalants (including Sharpies) can be similar to those of alcohol and include slurred speech, lack of coordination, euphoria, and dizziness.
Answer:
Becuse magnesium is a earth alkaline metal and oxygen is a nonmetal(read explanation)
Explanation:
Magnesium has 2 valence electrons where oxygen has 6 valence electrons. Magnesium has tendency to give electrons to oxygen and oxygen has tendency to gain electrons. They are both trying to complete their last shell to 8 which is called the octet rule. Because they both want to complete each other because of the reasons that I told they combine to be stanle atoms like noble gases.
Answer:
Cr₂O₇⁻²(aq) and ClO₃⁻(aq)
Explanation:
At a redox reaction, one substance must be reduced (gain electrons) and others must be oxidized (lose electrons). To evaluate the potential of the substance to be reduced, it's placed a reaction, in standards conditions, with H₂.
The potential reduction is quantified by E°, and as higher is the value of E°, as easy is to the compound to be reduced. So, at a redox reaction, the compound with the greatest E° will be reduced, and the other will be oxidized, in a spontaneous reaction. The values of E° are:
RuO₄⁻(aq) to RuO₄²⁻(aq) E° = + 0.59 V (the reduction reaction is the opposite of the oxidation reaction).
Ni⁺²(aq) E° = -0.257 V
I₂(s) E° = +0.535 V
Cr₂O₇⁻²(aq) E° = +1.33 V
ClO₃⁻(aq) E° = +0.890 V
Pb²⁺(aq) E° = -0.125 V
So, the substances that have E° higher than the E° of the RuO₄⁻²(aq) are Cr₂O₇⁻²(aq) and ClO₃⁻(aq), which are the substances that can oxidize RuO₄⁻(aq) to RuO₄²⁻(aq).
There can be an electrolytic cell from iron and copper electrodes by connecting a a battery.
<h3>What is a voltaic cell?</h3>
A voltaic cell is a cell that produces energy via a spontaneous chemical reaction. An electrolytic cell produces energy by a nonspontaneous chemical reaction.
Now, we know that we can reverse the electrodes in the voltaic cell and connect a cell. In such case, we can be able to create an electrolytic cell from iron and copper electrodes.

Heat required = M * C * (delta T)
= (Mass)*(Specific heat)*(temperature change)
= 250 * 4.18* 52 = 54340Joules.
