Answer:
47.5 g of water can be formed
Explanation:
This is the reaction:
CH₄ + 2O₂ → CO₂ + 2H₂O
Methane combustion.
In this process 1 mol of methane react with 2 moles of oxygen to produce 2 moles of water and 1 mol of carbon dioxide.
As ratio is 1:2, I will produce the double of moles of water, with the moles of methane I have.
1.320 mol .2 = 2.64 moles
Now, we can convert the moles to mass (mol . molar mass)
2.64 mol . 18g/mol = 47.5 g
Answer:
There are 1.8021⋅1024 molecules of CH4 in 48 grams of CH4 .

Hello,
In this case, considering the given specific gravity we are to compute the density of the 64% HNO3 solution:
In such a way, since the given solution of nitric acid is 64 % by mass, we've got:
Thus, by using the previously computed density and the molar mass of HA (90.2 g/mol) we can compute the required molar concentration as follows:

Answer: The small intestine breaks down the food by using enzymes that were released from the pancreas and use the bile from the liver. The bile helps with the digestion of fat as well eliminating waste from the blood.
Explanation:
Answer: when concentrations of acid and base are same, pH = pKa
PH = 12.38 pOH = 1.62
Explanation: pKa= -log(Ka)= 12.38. PH + pOH = 14.00
