Its pH value signifies the variance from the neutral point of 7, where the farther you get from 7, the stronger the base or acid
Answer:
111 L
Explanation:
Calculation of moles of hydrogen gas:-
Mass of
= 18.6 g
Molar mass of
= 2.01588 g/mol
![Moles=\frac{Mass}{Molar\ mass}=\frac{18.6}{2.01588}\ mol=9.23\ mol](https://tex.z-dn.net/?f=Moles%3D%5Cfrac%7BMass%7D%7BMolar%5C%20mass%7D%3D%5Cfrac%7B18.6%7D%7B2.01588%7D%5C%20mol%3D9.23%5C%20mol)
According to the given reaction:-
![2C+2H_2+O_2\rightarrow CH_3COOH](https://tex.z-dn.net/?f=2C%2B2H_2%2BO_2%5Crightarrow%20CH_3COOH)
2 moles of hydrogen gas on reaction produces one mole of acetic acid gas.
So,
1 mole of hydrogen gas on reaction produces
mole of acetic acid gas.
Also,
9.23 mole of hydrogen gas on reaction produces
mole of acetic acid gas.
Moles of acetic acid gas = 4.615 moles
Given that:
Temperature = 35 °C
The conversion of T( °C) to T(K) is shown below:
T(K) = T( °C) + 273.15
So,
T = (35 + 273.15) K = 308.15 K
n = 4.615 moles
P = 1.05 atm
V = ?
Using ideal gas equation as:
![PV=nRT](https://tex.z-dn.net/?f=PV%3DnRT)
where,
P is the pressure
V is the volume
n is the number of moles
T is the temperature
R is Gas constant having value = 0.0821 L atm/ K mol
Applying the equation as:
1.05 atm × V = 4.615 moles ×0.0821 L atm/ K mol × 308.15 K
<u>⇒V = 111 L</u>
Extensive properties depend on the amount of substance. The volume of a sample is an extensive property: 1000 grams of water takes up more volume than 10 grams of water. Mass is also an extensive property.
Explanation:
Carolus Linnaeus was one of the foremost taxonomist that provided an insight into the grouping and classification of organisms.
He came up with the seven groups below;
Species
Genus
Family
Class
Order
Phylum
Kingdom
Organisms belonging to the same species group or taxa can reproduce to produce viable offsprings.
Answer:
d. 54.9 kPa
Explanation:
mmHg and Pa are units of pressure used in chemistry principally in the study of gases. 1mmHg is equal to 133.322Pa. 412mmHg are:
412 mmHg * (133.322Pa / 1mmHg) = 54929 Pa
The prefix K (Kilo) represents one thousand of the determined unit.
54929Pa are:
54929Pa * (1KPa / 1000Pa) = 54.9kPa
Right answer is:
<h3>d. 54.9 kPa
