Explanation:

Un elemento químico está compuesto por átomos específicos, por ejemplo el oxígeno, el helio, el sodio, cloro. Por otro lado, un compuesto químico es la combinación de dos o más elementos químicos diferentes, por ejemplo, cloruro de sodio, que forma por la combinación de sodio y cloro (NaCl), dióxido de carbono, que se forma por la unión de carbono con tres átomos de oxígeno (CO₃), agua que se forma por la combinación de dos átomos de hidrógeno con un átomo de oxígeno(H₂O), etc.

Answer:

2 grams.

Explanation:

H2 + O2 --->  H2O2

Using molar masses:

2*1 g hydrogen   reacts with 2*16  g oxygen.

so 2g H2 reacts with 32 g O2.

Answer:  There are therefore 6.02 × 1023 water molecules in a mole of water molecules.

Explanation: Hope this helps

Answer:

Bromine water reacts with ethane as it is able to break open the double bond, forming 1,2-dibromoethane. This double bond is not present in ethane, so bromine water does not react with it. This reaction is known as electrophilic addition.

Explanation:

Ethene will readily react with bromine, so the colour of the bromine water changes from red-brown to colourless. Bromine atoms will add across the double bond in ethene to produce just one product; 1,2-dibromoethane.

Answer:

The formation of a gas is a clue to chemical changes. The bubbles of gas that you observed form when an antacid is dropped into water is an example of change. Another clue that a chemical change has occurred is the formation of a solid.

Answer: 1.12 Liters

Explanation:

According to avogadro's law, 1 mole of every substance occupies 22.4 L at STP and contains avogadro's number [tex]6.023\times 10^{23}[/tex] of particles.

To calculate the moles, we use the equation:

[tex]\text{Number of moles}=\frac{\text{Given molecules}}{\text {avogadro's number}}=\frac{3.24\times 10^{22}}{6.023\times 10^{23}}=0.05moles[/tex]

1 mol of [tex]Cl_2[/tex] occupy = 22.4 L

Thus 0.05 mol of [tex]Cl_2[/tex] will occupy = [tex]\frac{22.4}{1}\times 0.05=1.12 L[/tex]

Answer:

freezing

Explanation:

When a solid reaches the temperature of its melting point, it can become a liquid. For water, the temperature needs to be a little over zero degrees Celsius (0oC) for you to melt. ... The reverse of the melting process is called freezing. Liquid water freezes and becomes solid ice when the molecules lose energy.

hope it becomes helpful to you ☺️☺️

Explanation:

Answer:

In fluorine, the electrons are tightly held to the nuclei. The electrons have little chance to wander to one side of the molecule, so the London dispersion forces are relatively weak. At a low enough temperature the molecules will all be solids. At a high enough temperature they will all be gases.

Answer:

The answer for this question is A. butylcyclohexane

Explanation:

Choose letter A

You welcome have a nice day.

Name of the given compound is butyl cyclohexane.

Cyclo alkanes are those organic compounds in which alkanes are present in the cyclic form.

In the nomenclature of cyclo alkane, name of the substitute is put before the name of the main ring. In the given structure number of carbons in ring is 6 so that given cycloalkane is cyclohexane and butyl group is attached as substitute. So name of the given compound is butyl cyclohexane.

Hence name of the compound is butyl cyclohexane.
