How to balance Na + FeBr3 →
Lubov Fominskaja [6]

Hey there!

Na + FeBr₂ → NaBr + Fe

Firstly, balance Br.

Two on the left, one on the right. Add a coefficient of 2 in front of NaBr.

Na + FeBr₂ → 2NaBr + Fe  

Next, balance Na.

One on the left, two on the right. Add a coefficient of 2 in front of Na.

2Na + FeBr₂ → 2NaBr + Fe

Lastly, balance Fe.

One on the left, one on the right. Already balanced.

Our final balanced equation:

2Na + FeBr₂ → 2NaBr + Fe

Hope this helps!

An air compressor takes atmospheric air (think about what pressure it is at) and pressures it up to 68 (psig). In the process, i
Aleks [24]

Answer:

5.19 m³  

Explanation:

Data Given:

initial Pressure P1 = atmospheric pressure

Reported atmospheric pressure =  14.696 psi

Final pressures P2 =  68 psi

initial Temperature T1 =  26 °C

final Temperature T2 =  48 °C

initial Volume V1= 13 m³

final Volume V2 = ?

Solution:

Formula will be used

                    P1 V1 / T1 = P2 V2 / T2

To calculate volume rearrange the above formula

                   V2 = (P1 V1) T2 / T1 P2 . . . . . . . .(1)

put values in equation 1

                  V2 = (14.696 psi x 13 m³) 48 °C / 26 °C x 68 psi

                  V2 = (191.05 psi m³) 48 °C / 1768 °C psi

                  V2 = (9170.3  psi m³ °C / 1768 °C psi

                  V2 = 5.19 m³

So, final volume is 5.19 m³
