Alcohol consumption can damage the digestive system and can increase the risk of alcohol-caused cancer and liver disease.
Answer:
At ambient pressure and temperature the isobaric specific heat, CP, of gaseous propane is 1.68 kJ/kg K or 0.402 Btu/lb °F = cal/g K, while the isochoric specific heat, CV, is 1.48 kJ/kg K or 0.353 Btu/lb °F = cal/g K.

Answer:
105 grams PbI₂
Explanation:
Pb(NO₃)₂ + 2KI => 2KNO₃ + PbI₂(s)
moles Pb(NO₃)₂ = 0.265L(1.2M) = 0.318 mole
moles KI = 0.293(1.55M) = 0.454 mole => Limiting Reactant
moles PbI₂ from mole KI in excess Pb(NO₃)₂ = 1/2(0.454 mole) = 0.227 mol PbI₂
grams PbI₂ = 0.227 mol PbI₂ x 461 g/mole = 104.68 g ≈ 105 g PbI₂(s)
409 g P2O5 2) 5.44 x 1025 atoms Cu
Nitrogen, arsenic, antimony & bismuth
Explanation:
Phosphorus belongs to the 15th group, that is nitrogen family.
Natures are decided by the number of valence electrons.
In a family, all elements have same outer electronic configuration or you say number of electrons.
General electronic con.: ns²np³
