Answer:
Explanation:
Temperature of gas in absolute scale T = 25 + 273 = 298 .
pressure of gas P = 1.013 x 10⁵ N / m²
density D = 1.799 kg / m³
= 1799 g / m³
From gas formula
PV / T = n R Where P is pressure , V is volume and T is absolute temperature , n is no of moles
P / T = n R / V
P / T = m R /M V where m is mass of gas and M is molecular weight .
m / V = D ( density )
P / T = DR/ M
PM / DT = R
Putting the values
1.013 x 10⁵ x 44 / (1799 x 298)
R = 8.314.09 J / K mole
Carbon dioxide (CO2) is a covalent compound because it is composed of carbon and oxygen. Herein both the elements i.e. C and O are non-metals.
These elements share the electrons. When electrons are shared, each
atom will contain 8 electrons in the outer shell. Due to this, all the atoms
of the CO2 will become stable and they will have a completed outer shell.
The lewis structure of CO2 is shown below:
Answer : The ratio of hydrogen and oxygen in water is, (2:1)
Explanation :
As we know that the chemical formula of water is, .
In , there are 2 atoms of hydrogen and 1 atom of oxygen.
As we are given that the volume of water is, 2 L. So, there is no matter what is the volume of water that means there is no role of volume of water.
The ratio of hydrogen and oxygen in water is, (2:1)
Thus, in 2 L volume of water, the ratio of hydrogen and oxygen in water is also same that is, (2:1)
