Elements in the fluorine column react with the elements in?

The elements in the same column as fluorine are called halogens, they are missing only one valence electron so they can bond with anything, as can any element except for the inert gasses, so im not sure what you're asking because they can react with anything. But to get a full valence shell with little work they would try to bond with alkali metals (the first column) because they can take the single valence electron that the metal has and complete their outer orbital.

for example Chlorine has 7 valence electrons and sodium has one valence electron, so the chlorine would take the one valence electron from the sodium and form Sodium Chloride

If one of the reactants in a reaction is Na2O, what is known about the products?

const2013 [10]

D. The products will have at least 2 Na atoms and 1 O atom.

<h3>Further explanation</h3>

If we refer to the law of mass conservation, which states that

In a closed system, the masses before and after the reaction are the same

then the number of atoms in the reactance will be the same as the number of atoms in the product

In this problem it is known that Na₂O is one of the reactants so that the product of Na atoms and O atoms will at least equal the number of atoms in the bond, namely 2 Na and 1 O

Like an example of this Na₂O reaction:

Na₂O + H₂O ⇒ 2 NaOH

Na : left =2, right = 2

O : left=2, right = 2

What reaction conditions most effectively conver a cabocxylic acid to a methly ester?

VLD [36.1K]

Answer:

Esterification reaction

Explanation:

When we have to go from an acid to an ester we can use the esterification reaction. On this reaction, an alcohol reacts with a carboxylic acid on acid medium to produce an ester and water. (See figure).

In this case, we need the methyl ester, therefore we have to choose the appropriate alcohol, so we have to use the methanol as reactive if we have to produce the methyl ester.

2H+ H- H+ n + energy

from an external source of power

Explanation:

The energy needed for nuclear fusion comes from an external source of power.

Nuclear fusion is the combination of small sized atomic nuclei to form larger ones.

The reaction releases a huge amount of energy but also requires a large activation energy to start up.

The energy input require to drive two nuclei into fusion comes from an external source.
Nuclear fusion has a high activation energy which serves as the energy barrier for this reaction to take place.
The energy comes from the surrounding and once initiated, spontaneous chain reactions are set up.

Answer:

A. 6atm

Explanation:

Using pressure law equation:

P1/T1 = P2/T2

Where;

P1 = initial pressure (atm)

T1 = initial temperature (K)

P2 = final pressure (atm)

T2 = final temperature (K)

According to this question;

P1 = 3 atm

P2 = ?

T1 = 120K

T2 = 240K

Using P1/T1 = P2/T2

3/120 = P2/240

Cross multiply

240 × 3 = P2 × 120

720 = 120P2

P2 = 720/120

P2 = 6atm

A chemistry teacher is able to grade chemistry labs at a rate of 5 labs for every 3 minutes. They need to grade 165 labs how man

PIT_PIT [208]

Answer:

1.65hr

Explanation:

Given parameters:

Number of labs = 5 labs

Time taken = 3 minutes

Unknown:

Time taken in hours to grade 165 labs = ?

Solution:

Let us find the rate of the teacher;

Rate = $\frac{number of labs}{time}$

Insert the parameters and solve;

Rate = $\frac{5}{3}$ = 1.67labs/min

Now;

Time to grade 165 labs = $\frac{number of labs}{rate}$

Time to grade 165 labs = $\frac{165}{1.67}$ = 98.8min

Since;

60min = 1hr

98.8min = $\frac{98.8}{60}$ = 1.65hr
