What happens to the rock along the ridge when new molten material erupts?

1 answer:

3 0

The molten material then spreads out, pushing the older rock to both sides of the ridge. As the molten material cools, it forms a strip of solid rock in the center of the ridge. Then more molten material flows into the crack. The material splits apart the strip of solid rock that formed before, pushing it aside. Hope this helps! (:

When potassium metal is placed in water a large amount of energy is released as potassium hydroxide and hydrogen gas are produce

Ann [662]

Explanation:

$2K(s)+2H_2O\rightarrow 2KOH(aq)+H_2(g)$

The given reaction is redox reaction but not combustion reaction.

Redox reaction : It is a chemical reaction in which oxidation and reduction occurs simultaneously.Oxidation is gaining of electrons and reduction is loosing of electrons.

$K\rightarrow K^++e^-$ oxidation

$2H^++2e^-\rightarrow H_2$ reduction

Potassium when reacts with water ,gives potassium ion in aqueous medium and combines with hydroxide ion present in water to form potassium hydroxide where as $H^+$ ions of water by gaining electrons (from potassium in water) gives hydrogen gas.

Hence , yes it is a redox reaction

Combustion reaction are the chemical reaction in which one reactant react with oxygen molecule to give heat and light.

Here in given reaction no oxygen molecule is appearing on reactant side.

Hence not a combustion reaction.

What is the chemical formula for aluminum sulfite?

gulaghasi [49]

Ions and charges= Al+3 SO3-2

The charges must add up to zero, in order for two +3 aluminum ions to cancel out three -2 sulfite ions.
Al+3 Al+3 SO3-2 SO3-2 SO3-2

So simply put : Al2(SO3)3

What can you conclude about the mass of iron (III) sulfide produced when 3.0 g of iron filings react completely with 2.5 g of ye

igor_vitrenko [27]

Answer : The mass of iron(III)sulfide is, 5.4288 g

Solution : Given,

Mass of iron, Fe = 3 g

Mass of sulfur, = 2.5 g

Molar mass of Fe = 56 g/mole

Molar mass of = 256 g/mole

Molar mass of iron(III)sulfide, = 208 g/mole

The balanced chemical reaction is,

First we have to calculate the moles of iron and sulfur.

From the balanced reaction, we conclude that

16 moles of Fe react with 3 moles of

0.054 moles of Fe react with moles of

Therefore, the excess reagent in this reaction is, Fe and limiting reagent is,

Now we have to calculate the moles of FeS.

As, 3 moles of gives 8 moles of

So, 0.0098 moles of gives moles of

The moles of = 0.0261 moles

Now we have to calculate the mass of .

Mass of = Moles of × Molar mass of

Mass of = 0.0261 g × 208 g/mole = 5.4288 g

Therefore, the mass of iron(III)sulfide is, 5.4288 g

Consider the following reaction:

mestny [16]

Equation: NH4HS(s) <=> NH3 (g) + H2S(g)

Kc = [NH3]eq[H2S]eq; where eq subscripts are used to indicate that those are the concentrations at equilibrium

Kc= 0.272 * 0.365 =0.09928
