The main difference is that in a plant cell there is only one vacuole while in an an animal cell there are many.  but the size is drastically different also.

Answer:

Major structural differences between a plant and an animal cell include: Plant cells have a cell wall, but animals cells do not. Cell walls provide support and give shape to plants. Plant cells have chloroplasts, but animal cells do not.

Elemental sulfur is one of the products of the gas-phase reaction of nitric acid and hydrogen sulfide. The other
Goshia [24]

Answer:

The manufacturing processes for liquefied petroleum gas are designed so that the majority, if not all, of the sulfur compounds are removed. The total sulfur level is therefore considerably lower than for other crude oil-based fuels and a maximum limit for sulfur content helps to define the product more completely. The sulfur compounds that are mainly responsible for corrosion are hydrogen sulfide, carbonyl sulfide and, sometimes, elemental sulfur. Hydrogen sulfide and mercaptans have distinctive unpleasant odors. A control of the total sulfur content, hydrogen sulfide and mercaptans ensures that the product is not corrosive or nauseating. Stipulating a satisfactory copper strip test further ensures the control of the corrosion.

Balance the following oxidation-reduction reactions, which take place in acidic solution, by using the "half-reaction" method.
LuckyWell [14K]
First identify which is being oxidized and reduced. In this case, the Mg is being oxidized and the Hg is being reduced. 

Mg --> Mg+2 
 
<span>Hg+2 --> Hg+1 
</span>
Then you have to balance each half reaction first with electrons before adding them together in one equation

Mg ⇒ Mg^{+2}  +  2e^{-1}

and

2Hg^{+2} + 2e^{-1} ⇒ Hg_{2} ^{+2}
 
and then combine them together to form 

Mg + 2 Hg^{+2} + 2e ⇒ Mg^{+2} + 2e ^{-} + 2 Hg^{+1} + 2 e^{-}

It isn't necessary to keep the electrons but its essential to know how many there are in order to know how many are in the equation in order to calculate the reaction energy. Note: A<span>dd H+ and H2O to balance the H's and O's in acidic solution if needed.</span>

Answer:

It conducts electricity

It conducts heat

Water is needed for rusting

Explanation:

Metals refer to elements that are found towards the left hand side of the periodic table of elements. They are found in groups 1- 13 and few of them are also found at the bottom of groups 14 and 15.

Now these metal have certain properties that are general to all of them. two of these properties listed among the options in the question are;

i) They conduct electricity

ii) They conduct heat

These properties apply to all metals universally.

Rusting is an electrochemical reaction in which hydrated iron III oxide is formed. In the electrochemical reaction, water in intimately involved in the process. Hence; oxygen and water are required for rusting to take place.
