SO SO C5H12 IS PENT-ANE PENTANE AND THERE ARE MULTIPLE FORMS OF IT
Answer: 600°C
Explanation:
This reaction is explained by Charles' law as the pressure is constant.
From the question, we obtained:
V1 = 67mL
T1 = 18°C = 18 +273 = 291K
V2 = 3V1 ( Vol is tripled) = 3x67 = 201mL
T2 =?
Applying the Charles' law,
V1 /T1 = V2 /T2
67/291 = 201 / T2
Cross multiply to express in linear form.
67xT2 = 291x201
Divide both side by 67, we have:
T2 = (291x201) /67
T2 = 873K
Converting to Celsius temperature, we have
T°C = K — 273
T°C = 873 — 273 = 600°C
Answer:
D
Explanation:
THERE ARE 3 HYDROGEN ATOMS AND 1 NITROGEN SUPPORTING THE FORMULA OF AMMONIA NH3 AND TOTAL ATOMS IS ALSO 4.
The amount of kilograms is 0.7718
Molar mass CCl₄ = 12 + 35.5 x 4 = 154 g/mol
number of moles:
74.41 / 154 => 0.48318 moles
1 mole ------------------- 6.02 x 10²³ molecules
0.48318 moles ----------- ?
molecules = 0.48318 x ( 6.02x10²³) / 1
molecules = 2.908 x 10²³ / 1
= 2.908 x 10²³ molecules
hope this helps!
