Answer:
It is false :l
Explanation:
Pahoehoe is a smooth and continuous lava crust. Pahoehoe forms when the effusion rate is low and consequently the velocity of lava flow is slow. Pahoehoe lava flow is usually at least 10 times slower than typical aa lava flow.

Answer:
Option C. Triple the number of moles
Explanation:
From the ideal gas equation:
PV = nRT
Where:
P is the pressure
V is the volume
n is the number of mole
R is the gas constant
T is the absolute temperature.
Making V the subject of the above equation, we have:
PV = nRT
Divide both side by P
V = nRT / P
Thus, we can say that the volume (V) is directly proportional to both the number of mole (n) and absolute temperature (T) and inversely proportional to the pressure (P). This implies that and increase in either the number of mole, the absolute temperature and a decrease in the presence will cause the volume to increase.
Thus, the correct option is option C triple the number of moles. This can further be seen as illustrated below:
Initial volume (V1) = 12 L
Initial mole (n1) = 0.5 mole
Final mole (n2) = triple the initial mole = 3 × 0.5 = 1.5 mole
Final volume (V2) =?
From:
V = nRT / P, keeping T and P constant, we have:
V1/n1 = V2/n2
12/0.5 = V2/1.5
24 = V2/1.5
Cross multiply
V2 = 24 × 1.5
V2 = 36 L.
Thus Option C gives the correct answer to the question.
<span>N2, penta means 5, so 5 oxygens

Answer:
Almost 3 snicker's bar will contain the worth of energy stored in the battery which makes option A correct (Fewer than 5)
Explanation:
Step 1
The energy stored in a charged battery is 840 Watt- hours
Recall from the question that 1 KWh = 3600 KJ
So how many Kilo-joules will be in 840 Watt- hours?
I will convert 840 Watt- hours to KWh = 840 / 1000
= 0.840 KWh
Since I KWh gives 3600 KJ
then, 0.840 KWh will give x
x = 3024 KJ
3024 KJ of energy is stored in the battery
Step 2
A snicker bar contains 250 cal and 1 cal = 4.184 KJ
Convert 250 cal to KJ?
250 cal = 1046 KJ
Each snicker bar contains 1046 KJ
To calculate how many snicker's bar worth energy stored in the battery will be (y) ?
y = 3024 / 1046
y = 2.9 snicker's bar approximately 3
The correct option is Fewer than 5
