The rest of the wood was burned into gases of equivalent weight.
<u>Explanation</u>:
The rest of the wood was burned into gases of equivalent weight.
- When wood is burnt in the open air, with the help of oxygen and heat, it is transformed into carbon dioxide, water vapor, and ashes.
- Ignition and combustion of wood mainly depend on pyrolysis which is also known as thermal combustion.
- The loss in weight of the ashes is due to the fact that gases and water vapor are also formed due to the combustion of wood.
Answer:
Physical properties increasing atomic number
Explanation:
The modern periodic table is arranged by the increasing atomic number and for that reason elements with similar chemical properties are in the same group
Answer:
10.56L
Explanation:
The following were obtained from the question given :
P1 = 845mmHg
V1 = 4.6L
P2 = 368mmHg
V2 =?
We can calculate the new volume by using Boyle's law as follows;
P1V1 = P2V2
845 x 4.6 = 368 x V2
Divide both side by 368
V2 = (845 x 4.6) / 368
V2 = 10.56L
It weathers it down until it is nothing but sediment in a river , lake or ocean
Answer: Option (e) is the correct answer.
Explanation:
Equilibrium reaction equation for the given reaction is as follows.
It is given that initial moles of HCNO is 0.20 mol and for NaCNO is 0.80 mol. 
of HCNO is 
mol.
Now, we will assume that at equilibrium there are x moles.
Initial: 0.20 0.80 0
Change: -x +x +x
Equilibrium: 0.20 - x 0.80 + x x
As the volume of the given solution is 1 liter, equilibrium concentration and moles are same.
![K_{a} = \frac{[CNO^{-}][H_{3}O^{+}]}{[HCNO]}](https://tex.z-dn.net/?f=K_%7Ba%7D%20%3D%20%5Cfrac%7B%5BCNO%5E%7B-%7D%5D%5BH_%7B3%7DO%5E%7B%2B%7D%5D%7D%7B%5BHCNO%5D%7D)
x = 
M
Then, pH = ![-log[H_{3}O^{+}]](https://tex.z-dn.net/?f=-log%5BH_%7B3%7DO%5E%7B%2B%7D%5D)
= 
= 4.30
Thus, we can conclude that pH of given buffer solution is 4.30.
