The  moles of ammonia  that  are needed to react completely with 3  moles of  phosphoric acid  is <u> 6 moles</u>

    <u><em>Explanation</em></u>

Step 1:

write the a balanced  chemical reaction  that occur between ammonia and phosphoric acid.

<em>3NH3 + H3PO4 → (NH4)3PO4</em>

Step 2: use of mole ratio of NH3 :H3PO4  to calculate moles of  NH3

that is, NH3: H3PO4   is 3:1 therefore the moles of NH3 = 3moles x 3/1 = 9 moles

3 moles of NH3 was in excess therefore  the  mole of NH3 that  reacted = 9-3 = 6 moles

What is the chemical formula for a compound between Al and F? AlF AlF 3 AlF 2 Al 3F
tester [92]

Answer:

AlF3

Explanation:

Aluminum fluoride (AlF3) is an inorganic compound in which aluminum and fluoride has ionic bond between each other.

Aluminum ( atomic number - 13) has 3 valence electrons and can lose 3 electrons to get a stable configuration while fluorine (atomic number - 9) can gain one electron to make a stable configuration. So in order to attain a stable configuration one aluminum (Al) atom form ionic bond with three fluorine atoms and form AlF3.

Hence, the chemical formula between  Al and F is AlF3.

Bogdan [553]

Explanation:

As it is given that stream A is super heated. From stream tables, we get that specific enthalpy, (h_{A}) is 3054.29 kJ/kg.

For stream B, it is saturated water at 25 degree celsius. It's h_{B} is 2546.54 kJ/kg.

Stream C, data will be as follows.

                P = 200 kPa,         \chi = 0.9

So, h_{c} = h_{f} + \chi \times h_{fg}  

        = 504.47 + 0.9 \times 2201.7

        = 2486 kJ/kg

Now, energy balance formula will be as follows.

            m_{A}h_{A} + m_{B}h_{B} = (m_{A} + m_{B})h_{c}

              3 \times 3054.29 + m_{B} \times 2546.54 = (3 + m_{B}) \times 2486

             m_{B} = 28.16 kg/s

Hence, inflow of saturated liquid is 28.16 kg/s. According to steam table, temperature of wet steam is 120.23^{o}C

Mass flow rate of out flow is 31.16 kg/s.
