Answer:
CnH2n+2
Explanation:
an alkane consists of hydrogen and carbon atoms arranged in a tree structure in which all the carbon–carbon bonds are single.
Answer:
The pressure inside the bottle is 92.678 atm.
Explanation:
An ideal gas is characterized by three state variables: absolute pressure (P), volume (V), and absolute temperature (T). The relationship between them constitutes the ideal gas law, an equation that relates the three variables if the amount of substance, number of moles n, remains constant and where R is the molar constant of the gases:
×××
In this case:
P= ?
V= 500 mL= 0.500 L
n= 60 g* = 2.07 moles
R= 0.082
T= 0 C= 273 K
Replacing:
P* 0.500 L= 2.07 moles* 0.082 * 273 K
Solving:
P= 92.678 atm
The pressure inside the bottle is 92.678 atm.
Molecular weight of P (Phosphorous) = 30.97g/mol
Hydrogen is just 1 g/mol.
How many moles is 34g of PH3?
Get the weight of PH3 (30.97 + (3X1)) = 33.97g/mol
So 34g/33.97g/mol = 1.0009 moles.
I bet for this problem it's easier to round this to 1.
If you look at just the moles in the equation:
P4(s) + 6 H2(g) → 4 PH3(g)
OR
1 + 6 → 4
If 1 (P4) gives us 4 (PH3), what gives us 1 (PH3)?
1/4 = x/1
solve for x
Answer: Asteroids are a concern to earth due to the energy they posses and most catch on fire when they enter earths atmosphere, making them a fire hazard. Asteroids are considered natural disasters.
