Answer:

6K + N₂ —> 2K₃N

Explanation:

K + N₂ —> K₃N

The above equation can be balanced as illustrated below:

K + N₂ —> K₃N

There are 2 atoms of N on the left side and 1 atom on the right side. It can be balance by putting 2 in front of K₃N as shown below:

K + N₂ —> 2K₃N

There are 6 atoms of K on the right side and 1 atom on the left side. It can be balance by putting 6 in front of K as shown below:

6K + N₂ —> 2K₃N

Now the equation is balanced.

Small children are occasionally injured when they try to inhale helium from

sattari [20]

Answer:

260 moles of Helium

Explanation:

V = 50L

T = 20°C = (20 + 273.15)K = 293.15K

P = 125 atm

R = 0.082 L.atm / mol. K

n = ?

From ideal gas equation,

PV = nRT

P = pressure of a given gas

V = volume it occupies

n = number of moles

R = ideal gas constant

T = temperature of the gas

PV = nRT

n = PV / RT

n = (125 * 50) / (0.082 * 293.15)

n = 6250 / 24.0383

n = 260.00 moles

The child inhaled 260 moles of Helium

Identify the single displacement reaction. C4H12 + 7O2 ⟶ 6H2O + 4CO2 2H2 + O2 ⟶ 2H2O Al2S3 ⟶ 2Al + 3S Cl2 + 2KBr ⟶ 2KCl + Br2

Varvara68 [4.7K]

Answer:- $Cl_2+2KBr\rightarrow 2KCl+Br_2$

Explanations:- The first reaction is combustion reaction as the hydrocarbon is burned in presence of oxygen to give carbon dioxide and water.

Second reaction is the synthesis reaction as in general a synthesis reaction looks like:

$A+B\rightarrow AB$

Third reaction is the decomposition reaction as it looks opposite of synthesis reaction.

$AB\rightarrow A+B$

In general, a single displacement reaction looks like:

$AB+C\rightarrow AC+B$

Fourth reaction is single replacement reaction as bromine is replaced by chlorine.

So, the correct choice is the last reaction, $Cl_2+2KBr\rightarrow 2KCl+Br_2$ .
