Answer:
Ca3(PO4)2 + 3H2SO4 —> 3CaSO4 + 2H3PO4
The coefficients are 1, 3, 3, 2
Explanation:
Ca3(PO4)2 + H2SO4 —> CaSO4 + H3PO4
From the above equation,
There are 3 atoms of Ca on the left and 1 atom of Ca on the right. To balance Ca, put 3 in front of CaSO4 as shown below
Ca3(PO4)2 + H2SO4 —> 3CaSO4 + H3PO4
Now, we have 3 atoms of SO4 on the right and 1atom on the left. To balance SO4, put 3 in front of H2SO4 as shown below:
Ca3(PO4)2 + 3H2SO4 —> 3CaSO4 + H3PO4
Looking closely, there are 6 atoms of H on the left and 3 on the right. Therefore, it is balanced by by putting 2 in front of H3PO4 as shown below:
Ca3(PO4)2 + 3H2SO4 —> 3CaSO4 + 2H3PO4
The coefficients are 1, 3, 3, 2
The pressure of the gas would be the dividend divided by the number of the second vi~2
Answer:
The volume is 16.7 liters.
Explanation:
STP conditions are:
1 atm as pressure
273 K as temperature (0°C)
So let's get the volume by the Ideal Gas Law, replacing the values.
P . V = n . R . T
1 atm . V = 0.750 moles . 0.082 L.atm /mol.K . 273 K
V = (0.750 moles . 0.082 L.atm /mol.K . 273 K) / 1 atm
V = 16.7 L
Biogenic
Explanation:
Biogenic amine producing bacterias are known to be the most problematic bacteria in the food industry. Examples of these bacteria strains are Lactobacillus, Lactococcus, Leuconostoc e.t.c.
- The biogenic amines produced by these bacteria are of serious health concerns in the food industry.
- These biogenic amines are important for the proper functioning of the human body when present in food in the right proportion.
- When their proportion is above the tolerated limit, they can cause food intoxication thereby leading to serious health hazards.
