Answer:
C
Explanation:
CH₄ is the formula for methane
Hey there!
Volume in mL :
1.68 L * 1000 => 1680 mL
Density = 0.921 g/mL
Therefore:
Mass = density * Volume
Mass = 0.921 * 1680
Mass = 1547.28 g
Answer:
C4H7OH + 6O2 => 4CO2 + 4H2O
Explanation:
hope This helps :)
Answer: there is more atoms of each element on the right.
Explanation:
On the left of the arrow you have:
Si-1
F-4
H-4
O-2
On the right of the arrow you have:
Si-3
F-6
H-8
O-4
A balanced equation always has the same amount of each element on the left of the arrow (the reactants) as the right (the products). This isn’t balanced because you have a lot more of each element on the right.
Answer: Molar concentration of the tree sap have to be 0.783 M
Explanation:
To calculate the concentration of solute, we use the equation for osmotic pressure, which is:
where,
= osmotic pressure of the solution = 19.6 atm
i = Van't hoff factor = 1 (for non-electrolytes)
R = Gas constant =
T = temperature of the solution =
Putting values in above equation, we get:


Thus the molar concentration of the tree sap have to be 0.783 M to achieve this pressure on a day when the temperature is 32°C
