An 8 oz. bottle of energy drink contains 6.0 g of protein, 2.0 g of fat, and 16.3 g of carbohydrate. The fuel value of this ener

valina [46]

Answer: The correct option is d) 460 kJ

Explanation:

We are given:

Content of fat in energy drink = 2.0 g

Content of protein in energy drink = 6.0 g

Content of carbohydrate in energy drink = 16.3 g

Also,

The fuel value of fat = 38 kJ/g

The fuel value of protein = 17 kJ/g

The fuel value of carbohydrate = 17 kJ/g

So, the fuel value of the energy drink will be:

Total fuel value = $(2.0g\times 38 kJ/g)+(6.0g\times 17 kJ/g)+(16.3g\times 17 kJ/g)$

Total fuel value = $[76+102+277]=460kJ$

Hence, the correct option is d) 460 kJ

Consider a certain type of nucleus that has a half-life of 32 min. calculate the percent of original sample of nuclides remainin

Irina18 [472]

t1/2 = ln 2 / λ = 0.693 / λ
Where t1/2 is the half life of the element and λ is decay constant.

32 = 0.693 / λ
λ = 0.693 / 32 (1)

Nt = Nο eΛ(-λt) (2)

Where Nt is atoms at t time, λ is decay constant and t is the time taken.
t = 1.9 hours = 1.9 x 60 min

From (1) and (2),

Nt = Nο e⁻Λ(0.693/32)*1.9*60
Nt = 0.085Nο

Percentage = (Nt/Nο) x 100%
= (0.085Nο/Nο) x 100%
= 8.5%

Hence, Percentage of remaining atoms with the original sample is 8.5%

If we have 1.23 mol of NaOH in solution and 0.85 mol of Cl2 gas is available to react, which one is the limiting reactant? Give

Vinil7 [7]

Answer:

NaOH is the limiting reactant.

Explanation:

Hello there!

In this case, since the reaction taking place between sodium hydroxide and chlorine has is:

$NaOH+Cl_2\rightarrow NaCl+NaClO+H_2O$
