Kinetic and potential energy, are the two main types of energy! Hope this helps:)
The correct answer among the choices given is option C. C6H9 is not an empirical formula. Because it can still be reduced to lower proportions. An empirical formula is a formula giving only the proportion of the elements but not the actual number of atoms.
Hey there!:
Balanced equation:
F2(g) + CaBr2(s) ---> CaF2 + Br2
1 mol F2 = 1 mol CaBr2
Calculation:
2.31 g CaBr2
* (1 mol CaBr2 / 199.886 g CaBr2) * (1 mol F2 / 1 mol CaBr2)
= 0.0115565 moles of F2:
Assuming F2 is an ideal
gas at these conditions:
P*V = n*R*T
Solving for V:
V = (n *R* T) / P
where :
n = 0.0115565 moles
R = 0.08206 atm·L/mol·K
Temperature in K = 35 + 273.15 => 308.15 K
P = 8.19 atm
Substituting numbers into V = (n x R x T) / P:
V = 0.0115565 * 0.08206 * 308.15 / 8.19
V = 0.29222 / 8.19
V = 0.0357 or 3.57*10⁻² L
You are correct!!!
Hope that helps!
Inside the ground, different types of rocks and minerals are pressed together. The pressure causes the rocks to go together and form the sediments. Examples of sedimentary rocks are: sandstone, siltstone, and shale.
