Answer: Gas giants have a larger orbital radii.

Explanation:

There are two type of planets present in our solar system:

1. Terrestrial planets: These planets are known as rocky planets or inner planets in our solar system. They are Mercury, Venus, earth and Mars. These planets lie close to earth and hence have smaller orbital radii.

2. Gas Giants: These planets are large planets which compose mostly gases. They are known as outer planets in our solar system. They are Jupiter, Saturn, Uranus and Neptune. These planets lie away from the sun and hence, have larger orbital radii.

Therefore, the gas giants have a larger orbital radii.

In the reaction FeCl2 + 2NaOH ->Fe(OH)2(s) + 2NaCl, if 6 moles of FeCl2 are added to 6 moles of Na0H, how many moles of NaOH

pogonyaev

Answer : The correct option is, (B) 6 mole

Explanation :

Given moles of $FeCl_2$ = 6 moles

Given moles of $NaOH$ = 6 moles

First we have to calculate the limiting and excess reagent.

The balanced chemical reaction is,

$FeCl_2+2NaOH\rightarrow Fe(OH)_2+2NaCl$

From the given balanced reaction, we conclude that

As, 1 moles of $FeCl_2$ react with 2 moles of $NaOH$

So, 6 moles of $FeCl_2$ react with $\frac{2}{1}\times 6=12$ moles of $NaOH$

From this we conclude that, $FeCl_2$ is an excess reagent and $NaOH$ is a limiting reagent because the given moles are less than the required moles and it limits the formation of product.

Thus, the number of moles of NaOH used up in the reaction = Required moles of NaOH - Given moles of NaOH

The number of moles of NaOH used up in the reaction = 12 - 6 = 6 moles

Therefore, the number of moles of NaOH used up in the reaction will be, 60 moles

Answer:

Electrons

Explanation:

Atoms can combine together and share electrons between them. Atoms that share electrons are linked to each other in a form, called a molecule that is in a lower energy state than either of the separate atoms alone.

What kind of chemical change do you think occurs when a banana peel turns brown in the open air?

Alisiya [41]

Rotting, and ageing. The banana peel ages faster in open air, and therefor begins to rot. Brow peels don't mean that the banana is rotted, however, it is a sign that it may begin to rot soon.

7. Which of the following is a chemical property?

Goryan [66]

Answer:

It ability to react with oxygen.

Explanation:

Freezing point and hardness can be altered. Physical properties can also be reversed. Chemical properties on the other hand cannot. The product after reaction with an element never changes.
