Answer:
Si las condiciones para que el magma permanezca líquido no perduran, el magma se enfriará y solidificará en una roca ígnea. Una roca que se enfría en el interior de la Tierra se denomina intrusiva o plutónica y su enfriamiento será muy lento, produciendo una estructura cristalina de granos grueso.

Answer:
FeS
Explanation:
The reason why their is no subscripts is because as put in the question, the charges are equivalent. As you can see, +2 and -2 equal each other out.
Note: S has a charge of -2, not +2. (Look at oxidation rules.)
Answer:
The molarity of a MnO4- solution
= 0.0342 M
Explanation:
Equation of reaction:
5Fe2 (aq) MnO4-(aq) 8H (aq) ---> 5Fe3 (aq) Mn2 (aq) 4H2O(l)
This is an example of redox titration.
Using titration formula:
CAVA/CBVA = NA/NB
where CA is the molarity of Fe2+ = (0.134 M)
CB is the molarity of MnO4- = (?????)
VA is the volume of Fe2+ = (30mL)
VB is the volume of MnO4- =(23.5mL)
NA is the numeric coefficient of Fe2+ in the equation of reaction = ( 5 )
NB is the numeric coefficient of MnO4- in the equation of reaction =(1)
Substituting the values into the formula;
0.134×30/CB×23.5 = 5/1
Therefore CB = 0.134×30/23.5×5
= 0.0342 M

Explanation:
In this case, we have to remember that if we want to remove water from the reaction vessel we have to heat the vessel. So, we can convert the liquid water into <u>gas water</u> and we can remove it from the vessel. In this case, the products of dehydration for both molecules are <u>(E)-4-methylpent-2-ene</u> and <u>cyclohexene</u> with boiling points of <u>59.2 ºC</u> and <u>89 ºC</u> respectively. The boiling point of water is <u>100 ºC</u>, therefore if we heat the vessel the products and water would leave the system, and the products would be lost.
