Answer:
Biomass to an Energy source
Explanation:
Researchers have developed a new catalyst that directly converts cellulose, the most common form of biomass, into ethylene glycol, an important intermediate product for chemical industry. Alternatives to fossil fuels and natural gas as carbon sources and fuel are in demand.
<span>Answer:
2 C8H18 + 25 O2 => 16 CO2 + 18 H2O
1.0 kg = 1000 g C8H18 = 1000 g / 114.2293 g/mole = 8.75 moles C8H18
8.75 moles C8H18 produce (16/2) (8.75) = 70 moles CO2
70 moles CO2 = (70 moles) (44.0096 g/mole) = 3081 g CO2 = 3.1 kg CO2</span>
Answer:
pH=8.676
Explanation:
Given:
0.75 M 
0.20 M 
The objective is to calculate the pH of the buffer using the kb for 
Formula used:
![pOH=pka+log\frac{[salt]}{[base]}\\](https://tex.z-dn.net/?f=pOH%3Dpka%2Blog%5Cfrac%7B%5Bsalt%5D%7D%7B%5Bbase%5D%7D%5C%5C)
pH=14-pOH
Solution:
On substituting salt=0.75 and base=0.20 in the formula
pH=14-pOH
On substituting the pOH value in the above expression,
pH=14-5.324
Therefore,
pH=8.676
Answer:
8 mol of hydrogen will react with 1 mol of sulfur.
Explanation:
We'll begin by writing the balanced equation for the reaction.
This is given below:
8H2 + S8 —> 8H2S
Now, let us carefully observe the mole ratio of the reactants.
This is illustrated:
The mole ratio of the reactants ( i.e H2 and S8) is 8 : 1
From the balanced equation above,
We can thus, concluded that:
8 moles of H2 will reacted with 1 mole of S8.
B- Carbon nitrogen and oxygen. All organisms are made up of carbon, oxygen is essential to breath, and nitrogen makes up most of earth's atmosphere.
