How many moles of oxygen are required to burn 3.0 mole of C10H8 (naphthalene)?
astra-53 [7]

Answer: 36 moles oxygen

Step-by-step explanation:

C10H8 + 12O2 ====》 10CO2 + 4H2O

From the equation of the reaction,

1 mole of napth requires 12 moles of O2

3 moles of napth would require x moles O2

X = (3 * 12) / 1

X = 36 moles of oxygen.

Therefore 3 moles of naphtalene (C10H8) would require 36 moles of oxygen

If a seed is planted, it has a 80% chance of growing into a healthy plant.
AlladinOne [14]

Answer:

0.336

Step-by-step explanation:

Use binomial probability:

P = nCr p^r q^(n-r)

where n is the number of trials,

r is the number of successes,

p is the probability of success,

and q is the probability of failure (1-p).

Here, n = 8, r = 7, p = 0.8, and q = 0.2.

P = ₈C₇ (0.8)⁷ (0.2)⁸⁻⁷

P = 0.336

My homework asks to evaluate this: 8-11 Times the square root of 25 over 121
navik [9.2K]
8 - 11 = -3. The square root of 25/121 =  (the square root of 25) / (the square root of 121) = 5/11 .   -3 x 5/11 = -3/1 x 5/11 = (-3 x 5) / (1 x 11) = (-15)/11 = -15/11.
