Answer:

They would be more efficient in ground fires since carbon dioxide is much greater in mass then oxygen, so its affected by gravity .

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.

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:

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.

Answer:

KCrO₃

Explanation:

26.6% K, 35.3% Cr and 33.0% O

The steps in obtaining the empirical formulae from percentage composition is given as;

Step 1:

Divide the percentage composition by the atomic mass of the elements

K = 26.6 / 39.0983  = 0.6803

Cr = 35.3 / 51.9961 = 0.6789

O = 33.0 / 16  = 2.0625

Step 2:

Divide all though by the smallest number (0.6789)

K = 0.6803 / 0.6789 = 1.002

Cr = 0.6789 / 0.6789 = 1

O = 2.0625 / 0.6789 = 3.038

The Empirical formular is the ratio between the elements. This given as;

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:

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: 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]
