Answer:
mass (m) of the snow that the backpacker collected= 0.855 kg
Explanation:
Given that:
Q = 643 kJ = 643000 J
ΔHfusion = 6.02 kJ/mol = 6020 J/mol
number of mole of water H2O = 
c = 4.18 J/g⋅K
ΔT = 100 K
Since there is a phase change from solid to liquid; then :
ΔH = 
However without the given mass; we substitute 
for the number of moles; so:
Q = 
m = 855 g
m = 0.855 kg
mass (m) of the snow that the backpacker collected= 0.855 kg
Answer:
Explanation:
Hydrocarbon:
a = An organic compound made up of only carbon and hydrogen.
Such as alkane, alkene, alkyne.
Cyclic hydrocarbon:
c = Carbon chain that form rings.
Such as benzene, cyclo heptane etc
Isomers:
d = Compounds with same molecular formula and different structural formula.
Alkanes:
e = refers to saturated hydrocarbons, no matter the shape
such as methane, ethane, propane etc.
Alkene:
f = Any hydrocarbon that have at lest one carbon carbon double bond.
such as ethene, propene, butene
Saturated hydrocarbons:
b = Carbon atoms are saturated with so many hydrogen atoms that no more bonds may be formed
such alkanes.
Answer:
2 chlorine atoms.
Explanation:
H₂ + Cl₂ → 2HCl
The Law of Conservation of Mass states that matter can neither be created nor destroyed in a chemical reaction.
If 2 molecules of Hydrogen and 2 molecules of Chlorine is present in the reactants, the same no. of atoms should also be present in the product.
∴ the no. of chlorine atoms in the product is 2.
Answer:
Carbon dioxide is an atmospheric constituent that plays several vital roles in the environment. It is a greenhouse gas that traps infrared radiation heat in the atmosphere. It plays a crucial role in the weathering of rocks. ... It is stored in biomass, organic matter in sediments, and in carbonate rocks like limestone.
