Sodium reacts with oxygen to produce sodium oxide.

Chemistry
1 answer:
Snezhnost [94]3 years ago
4 0

Answer:

Explanation:

a )

4Na(s) + O₂(g) - - 2Na₂O(s)

4 x 23g    32g           2x62

92 g of Na produces 124 g of Na₂O(s)

57.5 g of Na produces (124 / 92) x 57.5

= 77.5 g of Na₂O(s)

b )

92 g of Na requires 32 g of O₂

18 g of Na requires ( 32 / 92 ) x 18

= 6.26 g of O₂

c )

128 g of Na₂O(s) requires 32 g of O₂

75 g of Na₂O(s) requires ( 32 / 128 ) x 75

= 18.75 g of O₂

What is the number of waves that go by in a certain amount of time
Arte-miy333 [17]

Answer: frequency

Explanation:

The frequency of a wave is the number of cycles the wave complete in one second. It is measured in hertz (Hz) , gigahertz (GHz) or larger scales.

Frequency F is inversely proportional to period T, which is the time it takes a wave to complete a cycle.

I.e Frequency = 1/T

In the lewis structure of ch3oh, how many bonding pairs of electrons are there?
zysi [14]
Answer:
            There are five <span>bonding pairs of electrons in Methanol.

Explanation:
                   Those electron pairs which are being shared between two atoms in molecule are called as bonding pair electrons. While, those electron pairs which are not involved in bond formation and are not shared between two atoms are called as Non-Bonding electron pairs.
                   In molecule of Methanol as shown below, it can be seen that carbon atom is forming four bonds with three hydrogen atoms and one oxygen atom by sharing four electron pairs and oxygen is forming two bonds, one with carbon atom and one with hydrogen atom. There are two lone pair of electrons present on oxygen atom which are not taking part in and formation.</span>

The substrate is the same in parts a and b, however the mechanism that proceeds is different. Explain how the choice of solvent
GenaCL600 [577]

Answer:

See explanation

Explanation:

The reaction of a benzyl bromide with a nucleophile may proceed by SN1 or SN2 mechanism depending on the nature of the solvent used.

Since SN1 reaction involves the formation of a carbocation, it usually predominates in the presence of a poor nucleophiles and protic solvents. Hence when methanol is used as solvent and a poor nucleophile is used, SN1 mechanism predominates.

However, when acetone which is an aprotic solvent is used in the presence of a good nucleophile, SN2 reaction mechanism predominates.
