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!
1) Nuclear reactions involve a change in an atom's nucleus, usually producing a different element. Chemical reactions, on the other hand, involve only a rearrangement of electrons and do not involve changes in the nuclei. ... (3) Rates of chemical reactions are influenced by temperature and catalysts.
The answer would be 2.0 x 10^-1
Explain in terms of particle behavior why smoke particles cause the detector alarm to sound
Smoke detectors are of many types but they rely on the principle of diffusion of smoke. Diffusion is the movement of particles from a region of high concentration to a region of lower concentration. Smoke particles move in what is known as Brownian motion.
Answer:
36 loaves of bread and 18.48 ounces of mayonnaise are needed to make all of the sandwiches.
Explanation:
Number of slices of ham = 231
Given that each sandwich has 1 slice of ham.
Then 231 slices of ham will be in :
A single sandwich is made up of 2 bread slices , Then bread slices in 231 sandwiches will be :
Each bread slice is applied with 0.0500 ounce of mayonnaise.
Then 462 bread slices will have :
1 bread loaf = 13 bread slices
Then breads loves in 462 bread slices :
36 loaves of bread and 18.48 ounces of mayonnaise are needed to make all of the sandwiches.
