C.

Since they are covalent meaning there are not electrical forces interacting between the elements so the molecule moves together as a unit, and doesn't break down into it's respective elements

Answer: Option (C) is the correct answer.

Explanation:

A compound formed by sharing of electrons between its participating atoms is known as a covalent compound.

For example, CO_{2} is a covalent compound.

Most covalent compounds are non-polar in nature and they do not dissociate into ions when dissolved in a polar solvent.

Whereas a compound which are formed by transfer of electrons between its participating atoms is known as an ionic compound. These compounds are polar in nature and dissociate into ions when dissolved in a polar solvent like water.

Therefore, we can conclude that it is true regarding covalent substances placed in water that covalent substances don't dissociate into charged particles.

The given questions belongs to the concept of limiting reagent.

The number of moles of carbon dioxide produced when 4.6 moles of dioxygen reacts is 4.6 moles.

<h3 /><h3>What is Limiting Reagent ?</h3>

The limiting reagent (or limiting reactant or limiting agent) in a chemical reaction is a reactant that is totally consumed when the chemical reaction is completed.

Given ;

Moles of Oxygen = 4.6

To find;

Moles of Carbon di oxide = ?

The reaction that forms CO_2 is as follows:

C(s) + O_2(g) -->  CO_2(g)

This means that O_2 is consumed and  CO_2 is produced in a 1:1 ratio.

If we consume 4.6 mol  O_2, then we produce 4.6 mol  CO_2 .

Hence, 4.6 mol  CO_2 are produced when 4.6 mol of oxygen reacts.

¿Cómo afectaría la velocidad de una reacción si se enfría lentamente la mezcla de los reactivos? AYUDA
hodyreva [135]

Answer:

La velocidad de reacción se ralentizará más rápidamente de lo habitual.

Explanation:

Dado que los factores que influyen en la velocidad de una reacción química son;

1) Temperatura de la mezcla reaccionante

2) Concentración (para líquidos) y área superficial de presión (para gases) (para sólidos) de los reactivos

3) catalizador

4) Reactantes naturaleza

5) Orientación de las moléculas reactivas reactivas

Tenemos que, específicamente, disminuir la temperatura del reactivo disminuye la probabilidad de que las moléculas de los reactivos involucrados en colisiones dentro de la mezcla tengan suficiente energía (que es igual o mayor que la energía de activación, Ea) para que la reacción se complete . Es decir, habrá una disminución en las colisiones efectivas (colisiones que provocan una reacción) y la reacción se ralentizará.

Dado que la velocidad de reacción se ralentiza con el tiempo, los reactivos de enfriamiento lento ralentizan rápidamente la reacción.

How many grams of an 8% w/w progesterone gel must be mixed with 1.45 g of a 4% w/w progesterone gel to prepare a 5.5% w/w gel?
Nimfa-mama [501]

Answer: 0.87 g of an 8% w/w progesterone gel must be mixed with 1.45 g of a 4% w/w progesterone gel to prepare a 5.5% w/w gel.

Explanation:

According to the dilution law,

C_1w_1+C_2w_2=C_3w_3

where,

C_1 = concentration of ist progesterone gel = 8%w/w

w_1 = weight of ist progesterone gel  = x g

C_2 = concentration of another progesterone gel  = 4% w/w

w_2 = weight of another progesterone gel = 1.45 g

C_3 = concentration of resulting progesterone gel  = 5.5%w/w

w_3 = weight of resulting progesterone gel  = (x+1.45) g

8\times x+4\times 1.45=5.5\times (x+1.45)

x=0.87

Thus 0.87 g of an 8% w/w progesterone gel must be mixed with 1.45 g of a 4% w/w progesterone gel to prepare a 5.5% w/w gel.
