Yes. The model represents atoms rearranging to produce a new compound.

<h3>What chemical reactions?</h3>

They are reactions involving the breakage of bonds and rearrangement of atoms in reactants to form products.

In the model, the bonds between hydrogen and chlorine were broken. Thereafter, each hydrogen and chlorine molecule linked up to form hydrogen chloride.

Thus, the model shows atoms rearranging to produce a new compound.

How many atoms are in 35 grams of table salt

Slav-nsk [51]

Adopting the number of avogrado 6.02 * 10²³ / mol
<span>Sodium chloride (table salt)</span> Molar Mass = 58.44 g / mol
We will first have to find the number of moles in 35 grams of the element, like this:

1 mol ----------------- 58.44 g
X ---------------------- 35 g

58.44 * x = 35 * 1
58.44x = 35
$X = \frac{35}{58.44}$
X = 0.598904...
X ≈ 0.60<span> mol </span>

Now we will find how many atoms there are in 0.60 mol of this element, like this:

1 mol -------------------- 6.02 * 10²³ atoms
0.60 mol ----------------- X

X = 0.60 * 6.02 * 10²³
$\boxed{\boxed{x \approx 3.612 * 10^{23}\:atoms}}\end{array}}\qquad\quad\checkmark$

In 1939, the use of DDT (a powerful synthetic chemical) as an insecticide was discovered. The United States adopted its widespre

Natasha_Volkova [10]

Main advantages of DDT are the insecticide property and the knoledge about its chemical synthesis.

Explanation:

At that time in 1939 it was discovered that DDT have insecticide properties. It is a useful property because it allows inhibition of insects populations in large areas. Killing insects will reduce the diseases transmitted by them as typhus and malaria. More over you prevent the destruction of the agricultural crops by the harmful insects.

However the synthesis of the molecule was known way back in 1874. From that time it was plenty of time in which chemistry knowledge evolved so the synthesis at kilograms scale was implemented. High quantities of DDT molecule become available for the market so that in 1945 was available as agricultural insecticide.

It was discovered that DDT have bad effects for human health and also over time some insects developed resistance and their were not affected anymore by the molecule.

You may find the chemical structure of DDT in the attached figure.
