False, it will turn the litmus paper blue
The correct option is B.
Carbon is an element with an atomic number of 6. Each atom of carbon is made up of electron, proton and neutron. Carbon has six protons and six neutrons in its atom but its number of neutrons differ. This is because carbon exhibit isotopy. The isotopes of carbon are: carbon 12, carbon 13 and carbon 14. Carbon 12 has 6 neutrons, carbon 13 has 7 neutrons and carbon 14 has 8 neutrons.
Answer:
38.4 atm.
Explanation:
- We can use the general law of ideal gas:<em> PV = nRT.</em>
where, P is the pressure of the gas in atm.
V is the volume of the gas in L.
n is the no. of moles of the gas in mol.
R is the general gas constant,
T is the temperature of the gas in K.
- If n and T are constant, and have different values of P and V:
<em>(P₁V₁) = (P₂V₂).</em>
P₁ = 3.0 atm, V₁ = 3200 L,
P₂ = ??? atm, V₂ = 250.0 L.
∴ P₂ = (P₁V₁)/(V₂) = (3.0 atm)(3200 L)/(250.0 L) = 38.4 atm.
