Earth has approximately 600,000,000 meters of coastline. If we assume this entire length of coastline has sandy beaches 60 meter
VashaNatasha [74]

Answer:

7 and 11

Explanation:

The amount of sand on the beaches can be found using this formula:

volume (m3) = length (m) × width (m) × depth (m)

(6 × 108 m) × 60 m × 20 m = 7 × 1011 m3

Therefore, there would be a total of 7 × 1011 cubic meters of sand on the beaches.

Explain, in terms of particles, what happens when methane boils and why
Ronch [10]

Answer:Butane > ethane > methane, because between bigger molecules there are stronger van der Waals forces and also higher molar mass means they need to be given more energy to have enough kinetic energy to move quickly, freely in gas.

There are multiple butene isomers (Butene) and some (2-Butenes - cis and trans) actually have higher boiling point than n-Butane (there is also Isobutane, of course, with quite much lower boiling point than all of them) and some (1-Butene, Isobutylene) have lower, so this isn't really a fair or simple question. But on simplest level, it can again be said that 1-butene has lower boiling point because it has very similar shape but slightly lower molar mass (2H less) than n-butane.

In 1901, Thomas Edison invented the nickel-iron battery. The follwing reaction takes place in the battery.
lys-0071 [83]

Answer: The number of moles of Fe(OH)_2  produced are, 3.60 moles.

Explanation :

First we have to calculate the limiting and excess reagent.

The balanced chemical equation is:

Fe(s)+2NiO(OH)(s)+2H_2O(l)\rightarrow Fe(OH)_2(s)+2Ni(OH)_2(aq)

From the balanced reaction we conclude that

As, 1 mole of Fe react with 2 mole of NiO(OH)

So, 3.60 moles of Fe react with 3.60\times 2=7.2 moles of NiO(OH)

From this we conclude that, NiO(OH) is an excess reagent because the given moles are greater than the required moles and Fe is a limiting reagent and it limits the formation of product.

Now we have to calculate the moles of Fe(OH)_2

From the reaction, we conclude that

As, 1  mole of Fe react to give 1 mole of Fe(OH)_2

So, 3.60 mole of Fe react to give 3.60 mole of Fe(OH)_2

Therefore, the number of moles of Fe(OH)_2  produced are, 3.60 moles.
