According to Gay -Lussac's law, the pressure of the can if it is heated to 1270°C is 4295.53 mm Hg.
It is defined as a gas law which states that the pressure which is exerted by the gas directly varies with its temperature and at a constant volume.The law was proposed by Joseph Gay-Lussac in the year 1808.
The pressure of the gas at constant volume reduces constantly as it is cooled till it undergoes condensation .If a graph of pressure versus temperature is plotted it is a straight line which passes through the origin .
The equation is given as, P₁/T₁=P₂/T₂
On substitution of values as ,P₁=760 mm Hg,T₁=273 K,T₂=1543 K
P₂=1543×760/273=4295.53 mm Hg.
Thus, the pressure of gas is 4295.53 mm Hg if it is heated up to 1270°C.

Answer:
The process is called Nitrogen fixation
Explanation:
The nitrogen fixation is a process carried out by some prokaryotic microorganisms (bacteria), specifically those have the presence of the nitrogenase enzyme. The bacteria absorb the atmospheric nitrogen (N2) from the roots of plants, and the nitrogenase enzyme, with the help of two proteins that act as electron donors and acceptors (nitrogenase complex) reduce the nitrogen to ammonia (NH3), then the ammonia is ionized to NH4+ (ammonium). Followed by that, the ammonia is oxidated to nitrates and nitrites, which are finally absorbed again by plants.
Answer:
Ka = 1.5 -10^-5
Explanation:
Step 1: Data given
Molarity of the solution = 0.25 M
pH = 2.71
Step 2 The equation
C3H7COOH + NaOH ⇆ C3H7COONa + H2O
Step 3: Calculate pKa
pH = (pKa-log[acid])/2
2pH = pKa -log[acid]
pKa = 2pH +log[acid]
⇒with pH = 2.71
⇒with log[acid] = -0.60
pKa=2*2.71 -0.60
pKa = 5.42 - 0.60
pKa = 4.82
Step 4: Calculate Ka
pKa = -log(Ka)
Ka = 10^-4.82
Ka = 1.5 -10^-5
Answer:
Explanation:
C7H14 has 3 isomers. Cycloheptane, methylcyclohexane and heptene all share the same formula.
The empirical formula of C7H14 is C7H14.
The empirical formula of C7H14 is C7H14. An empirical formula represents the simplest ratio of elements in a compound. In this case, there are 7 carbon (C) atoms and 14 hydrogen (H) atoms. The ratio between the two elements is 1:2, so the empirical formula is C7H14.
