The statement is false as 85675 grams of nitrogen dioxide is produced instead of 20 grams.
Explanation:
Balance equation for the reaction:
2NO + ⇒ 2N
Data given:
mass of nitrogen produced = 20 gram
mass of oxygen = 29.8 litres or 29800 grams
0xygen is the limiting reagent so,
number of moles of oxygen: (atomic mass of 1 mole 32 grams/mole
number of moles =
putting the values in the equation:
=
= 931.5 moles
1 mole of oxygen reacts to give 2 moles of NO2
931.5 moles of oxygen will give x moles
=
1862.5 moles of NO2 produced
in grams
mass = number of moles x atomic mass
mass = 1862.5 x 46.00
= 85675 grams
The statement is false as 85675 grams of nitrogen dioxide is produced instead of 20 grams as said in question.
1 can of soda has 12 ounces * 2.01 mg/oz = 24.12 mg of caffeine.
1 gram = 1000 mg
10 grams x 1000 mg = 10,000 mg
Divide total mg by mg per can:
10,000 / 24.12 = 414.59 cans
Round to 415 cans
Initial Conditions:
Volume=v1= 3.5 L
Temperature= T1 =298K
Final Conditions:
Temperature= T2= 285K
Volume= v2= ?
Use the general gas equation;
P1*v1/T1 = P2*v2/T2
Note:
Pressure is constant
so the equation become,
v1/T1 = v2/T2
3.5/298 = v2/285
v2 = 3.347 L
Answer:
An observation
Explanation: observation can also involve the perception and recording of data via the use of scientific instruments. The term may also refer to any data collected during the scientific activity
