<u>Given:</u>
Volume of gas = 215 ml
Initial temperature T1 = 20C = 20 +273 = 293 K
Initial pressure P1 = 1 atm
Final pressure P2 = 1.5 atm
<u>To determine:</u>
The final temperature T2
<u>Explanation:</u>
Based on Gay-Lussac's Law:
P α T
Therefore we have the relation:
P1/T1 = P2/T2
T2 = P2T1/P1 = 1.5 *293/1 = 439.5 K
Converting from Kelvin to degrees C we have:
T2 = 439.5 - 273 = 166.5 C
Ans: The final temperature is 439.5 K or 166.5 C
Answer:
B
Explanation:
Carbon Dioxide is one of waste produced from Our cells during respiration. The circulatory system carries Carbon Dioxide from cells either in haemaglobin in RBC or plasm. The Carbon Dioxide being carried to blood cappilaries near alveoli before diffused into alveoli and then being removed away by respiratory system in the process of respiration while we exhale
Answer:
2193.8 PSI is the pressure in the tank
Explanation:
We apply the Ideal Gases Law to solve this:
P . V = n . R . T
T° is the temperature in K, so we must do the conversion:
35°C + 273 = 308K
P . 1650L = 9750 mol . 0.082 L.atm/mol.K . 308K
P = (9750 mol . 0.082 L.atm/mol.K . 308K) / 1650L → 149.24 atm
Let's make the conversion:
1 atm = 14.7 PSI → 149.24 atm . 14.7 PSI / 1 atm = 2193.8 PSI
The theoretical yield is calculated as follows
write the equation for reaction
that is 2 Zn + I2 ------> 2 znI
then find the moles of Zn used
moles= mass/molar mass
= 125/ 65.4 = 1.911moles
by use of mole ratio between Zn to Zni which is 2:2 the moles of ZnI is also= 1.911moles
theoretical yield is therefore= moles of ZnI x molar mass of znI
= 1.911 moles x 319.2 g/mol = 609.99 grams

Explanation:
Vinegar (from the Latin «vinum acre», «sour wine») [1] is a liquid miscible in water, [2] with a sour flavor, which comes from the acetic fermentation of alcohol, such as that of wine and apple ( by means of
