Answer:
make contact with the heat source
Explanation:
Cyclopentane is NOT an isomer of pentane.
Isomers must have the same molecular formula.
The molecular formula of pentane is C₅H₁₂, while the molecular formula of cyclopentane is C₅H₁₀.
The two molecules cannot be isomers.
Speed = distance/time
10m/2s = 5m/s
The speed is 5 m/s
Answer:
The atomic number or proton number (symbol Z) of a chemical element is the number of protons found in the nucleus of every atom of that element. The atomic number uniquely identifies a chemical element.
Explanation:
Answer:
102.26 moles of helium were required to Fill the Goodyear Blimp
Explanation:
To solve this question we need to use combined gas law:
PV = nRT
<em>Where P is pressure, V is volume of gas (2500L), n are moles of gas (Our incognite), R is gas constant (0.082atmL/molK) and T is absolute temperature</em>
<em />
Assuming atmospheric condition we can write P = 1atm and T = 25°C = 298.15K
Replacing:
PV/RT = n
1atm*2500L / 0.082atmL/molK*298.15K = n
<h3>102.26 moles of helium were required to Fill the Goodyear Blimp</h3>
