Im sorry really dont know the answer
Answer:
Mass = 72.52 g
Explanation:
Given data:
Mass of hydrogen phosphate produced = ?
Mass of P₂O₅ react = 105.9 g
Solution:
Chemical equation:
P₂O₅ + 3H₂O → 2H₃PO₄
Number of moles of P₂O₅:
Number of moles = mass/molar mass
Molar mass of P₂O₅ 283.9 g/mol
Number of moles = 105.9 g/ 283.9 g/mol
Number of moles = 0.37 mol
Now we will compare the moles of P₂O₅ with H₃PO₄ from balance chemical equation.
P₂O₅ : H₃PO₄
1 : 2
0.37 : 2/1×0.37= 0.74 mol
Mass of H₃PO₄ :
Mass = number of moles × molar mass
Mass = 0.74 mol × 98 g/mol
Mass = 72.52 g
The answer would be:
A. Cancel out CO because it appears as a reactant in one intermediate reaction and a product in the other intermediate reaction.
In this question, there are two half-reaction equations. To merge them up, you need to add the reactant with the reactant, then the product with the product. If there is a molecule on both side, you can cancel them. The full reaction would be:
C+ 1/2 O2 + CO + 1/2O2 ==>CO+ CO2 -----> remove CO from both side
C+ O2 ==>CO2
Answer:
The answer is "2.5 mole"
Explanation:
The reaction for producing 
can be defined as follows:
Reaction:
According to the above reaction, to produce 2 moles of we need 1 mole of nitrogen:
So, according to the question to produce 5.0 mole the required 
:
To produce 5.0 mole we need 2.5 mole
A dependible common measurement
