Answer:

Sex refers to biological differences between males and females. For example, chromosomes (female XX, male XY), reproductive organs (ovaries, testes), hormones (oestrogen, testosterone). Gender refers to the cultural differences expected (by society / culture) of men and women according to their sex.

Aluminum and cloride undergoes a synthesis reaction if 8molnof Al reacts with 10mol of cl, what is the maximum amount of AlCl3 c

Inessa [10]

<u>Answer:</u> The mass of $AlCl_3$ produced is 889.38 g

<u>Explanation:</u>

We are given:

Moles of Al = 8 mol

Moles of $Cl_2$ = 10 mol

For the given chemical reaction:

$2Al+3Cl_2\rightarrow 2AlCl_3$

By stoichiometry of the reaction:

If 3 moles of chlorine gas reacts with 2 moles of Al

So, 10 moles of chlorine gas will react with = $\frac{2}{3}\times 10=6.67mol$ of Al

As the given amount of Al is more than the required amount. Thus, it is present in excess and is considered as an excess reagent.

Thus, chlorine gas is considered a limiting reagent because it limits the formation of the product.

By the stoichiometry of the reaction:

If 3 moles of $Cl_2$ produces 2 mole of $AlCl_3$

So, 10 moles of $Cl_2$ will produce = $\frac{2}{3}\times 10=6.67mol$ of $AlCl_3$

The number of moles is defined as the ratio of the mass of a substance to its molar mass. The equation used is:

$\text{Number of moles}=\frac{\text{Given mass}}{\text{Molar mass}}$

We know, molar mass of $AlCl_3$ = 133.34 g/mol

Putting values in above equation, we get:

$\text{Mass of }AlCl_3=(6.67mol\times 133.34g/mol)=889.38g$

Hence, the mass of $AlCl_3$ produced is 889.38 g

Unlike acceleration and velocity, speed does NOT need to specify

jarptica [38.1K]

Answer:

C) mass.

Explanation:

The speed of a body is given by the relation between the displacement of a body in a given time. It can be considered the greatness that measures how fast a body moves.

Speed analysis is divided into two main topics: average speed and instantaneous speed. It is considered a vector quantity, that is, it has a module (numerical value), a direction (Ex .: vertical, horizontal) and a direction (Ex .: forward, upwards). However, for elementary problems, where there is displacement in only one direction, the so-called one-dimensional movement, it is advisable to treat it as a scalar quantity (with only numerical value).

The mass of an object is not an important factor in determining the speed of that object. However, time, direction and distance are important factors in determining speed.

One container contains 4 moles of carbon dioxide. Calculate: 1) The number of carbon dioxide molecules? 2)The number of carbon a

grandymaker [24]

1. 2.408 x 10²⁴ molecules

2. 2.408 x 10²⁴ atoms

3. 4.816 x 10²⁴ atoms

<h3>Further explanation</h3>

Given

4 moles of Carbon dioxide.

Required

Carbon dioxide molecules

Carbon atoms

Oxygen atoms?

Solution

1 moles = 6.02 x 10²³ particles(molecules, atoms, ions)

1. Carbon dioxide molecules :

= 4 moles x 6.02 x 10²³

= 2.408 x 10²⁴ molecules

2. The number of Carbon atoms

In CO₂, there is 1 atom C, so the number of atoms :

= 1 x 2.408 x 10²⁴

= 2.408 x 10²⁴ atoms

3. The number of Oxygen atoms :

In CO₂, there is 2 atom O, so the number of atoms :

= 2 x 2.408 x 10²⁴

= 4.816 x 10²⁴ atoms
