If we had 79.3 grams of Xe, would we expect a volume that is

Chemistry

Shtirlitz [24]3 years ago
6 0

Answer:

13.44 liters of Xe

Explanation:

First, change grams to moles by dividing the mass given (79.3) by the mass of one mole of Xe (131.3) to get .6 moles.

Now you turn moles to liters (aka volume) by multiplying the number of moles of Xe (.6) by 22.4 to get 13.44 liters of Xe

When dipentyl ether is treated with HI, what type of reaction occurs? both SN1 and SN2 SN2 E1 SN1 E2
masha68 [24]

Answer:

SN2

Explanation:

The first step of ether cleavage is the protonation of the ether since ROH is a better leaving group than RO-.

The second step of the reaction may proceed by either SN1 or SN2 mechanism depending on the structure of the ether. Methyl and primary ethers react with HI by SN2 mechanism while tertiary ethers react with HI by SN1 mechanism. Secondary ethers react with HI by a mixture of both mechanisms.

Dipentyl ether is a primary ether hence when treated with HI, the reaction with HI proceeds by SN2 mechanism as explained above.

These elements belong to different Physical and chemical properties , which means they have different and different . Sodium is
Finger [1]

Answer:

Check explanation section.

Explanation:

Yes, that is true. Sodium with chemical symbol Na belongs to the group 1 on the periodic table. Group 1 elements are known as Alkali metals. Other elements in the group are Caesium, lithium, Rubidium, francium and potassium.

Neon belongs to the noble gas of group 8/0.

Sodium is very reactive and and good conductor of electricity. Sodium reacts with water for the production of hydrogen (NB: this reaction is vigorous).

2Na(s) + 2H2O ------------> 2NaOH + H2(g).

They can react with nonmetals such as the halogens. For instance;

Na + Cl2 -------------------------------> 2NaCl.

Sodium is ductile and have low melting point( but high compared to neon).

Neon is not active chemically and it has no odour and no color
