False the heat does not matter with the wind
Atoms that makes up carbon and water are found in table sugar.
Explanation:
These three substances are made up of similar atoms. Carbon is a single element on its own, water is a polar covalent compound and table sugar is a compound.
- The symbol of carbon is C, symbol of water is H₂O and table sugar is C₁₂H₂₂O₁₁
- From the above, one can conclude correctly that table sugar can be expressed in terms of carbon and water.
- Table sugar will then consist of 12 Carbon atoms, and 11 molecules of water.
- Simply 12(C) + 11(H₂O)

In a redox reaction electrons are lost and gained in equal numbers. The species that is oxidized gives electrons to the species that is reduced. I hope this helps. Let me know if anything is unclear.
Answer:
P₂ = 5.550213 Pa
Explanation:
Given data:
Heat of vaporization = 376.6 KJ/mol ( 376600 j/mol)
R = 8.3143 j mol⁻¹ K⁻¹
Temperature = T1 = 100 °C = 100 + 273 = 373 K
Temperature = T2 = 508.0 °C = 508.0+273 = 781 K
Pressure at 100°C= P1 = 1.6 × 10⁻³² Pa
Pressure at 508.0 °C = ?
Solution:
ln P₁/P₂ = ΔH /R ( 1/T₂ - 1/T₁)
ln (1.6 × 10⁻³² Pa) - ln (P₂) = 376600 j. mol⁻¹ / 8.3143 j mol⁻¹ K⁻¹ ( 1/T₂ - 1/T₁)
-73.212719 - ln (P₂) = 45295.45 (0.001280 - 0.002680)
-73.212719 - ln (P₂) = 45295.45 (-0.00414)
- ln (P₂) = -63.41363 + 73.212719
- ln (P₂) = 9.799089
P₂ = e⁻⁹°⁷⁹⁹⁰⁸⁹
P₂ = 5.550213 Pa
I would say D: 2 and 4.
The first line of the question is very important. X reacts with Y to form a gas.
For 2, we let the gas escape and measure the change in mass during the reaction.
For 4, we capture the change in volume of gas during the reaction.
1 does not work: some of the gas escapes through the cotton and the gas captured is not recorded correctly.
3 does not work: the gas is trapped and the mass balance does not record a change in mass.
