(C) The silver carp is another species native to Asia that was introduced to aquaculture operations and sewage treatment ponds i

n the Mississippi River valley to control excess algae
accumulation. The species escaped from these operations into the Mississippi River and its tributaries and has the potential to invade the Great Lakes. Scientists are concerned that this
species is having severe negative impacts on these areas.
() Propose a potential solution, other than physically removing the carp from the rivers, to manage the problem of the invasive silver carp in the United States.

Black_prince [1.1K]
Let us  assume propane was the fuel
C3H8(g) + 5O2(g) ---> 3CO2(g) + 4H2O(g) = 2217kJ
1 mole ofpropane produces 3 moles of CO2 
heat absorbed by pork = 0.11 x 2217
                                     = 243.87 kJ/mol
number of moles of propane = 1700kJ / 243.87 kJ/mol
                                              = 6.971 moles
1 mole of C3H8 = 3 moles ofCO2
6.971 moles of C3H8 = ?
3 x 6.971 = 20.913 moles of CO2
Convert to grams
mass = MW x mole
          = 44 x 20.913
          = 920.172g of CO2 emitted

Oksanka [162]

Answer:

Answer B

Explanation:

By definition mixtures are combinations of substances physically prepared and physically separated. Mixtures are classified as 'homogeneous mixtures' and 'heterogeneous mixtures'. For homogeneous mixtures all components are dissolved, with solute evenly distributed throughout the solution and assumes state of solvent. 'Heterogeneous mixtures' have inconsistent properties throughout and solute concentration is not consistent throughout the mixture.

The mass percent of carbon in a typical human is 18%, and the mass percent of 14C in natural carbon is 1.6 × 10-10%. Assuming a
Tema [17]

Answer:

4066 decay/s

Explanation:

Given that:-

The weight of the person is:- 190 lb

Also, 1 lb = 453.592 g

So, weight of the person = 86182.6 g

Also, given that carbon is 18% in the human body. So,

\%\ Carbon=\frac{18}{100}\times 86182.6\ g=15512.868\ g

Carbon-14 is 1.6\times 10^{-10}\ \% of the carbon in the body. So,

\%\ Carbon-14=\frac{1.6\times 10^{-10}}{100}\times 15512.868\ g=2.48\times 10^{-8}\ g

Also,

14 g of Carbon-14 contains  6.023\times 10^{23} atoms of carbon-14

So,  

2.48\times 10^{-8}\ g of Carbon-14 contains  \frac{6.023\times 10^{23}}{14}\times 2.48\times 10^{-8} atoms of carbon-14

Atoms of carbon-14 =  1.07\times 10^{15}

Given that:

Half life = 5730 years

t_{1/2}=\frac {ln\ 2}{k}

Where, k is rate constant

So,  

k=\frac {ln\ 2}{t_{1/2}}

k=\frac{ln\ 2}{5730}\ years^{-1}

The rate constant, k = 0.00012 years⁻¹

Also, 1 year = 3.154\times 10^7 s

So, The rate constant, k = \frac{0.00012}{3.154\times 10^7} s⁻¹ = 3.8\times 10^{-12}\ s^{-1}

Thus, decay events per second = K\times atoms decayed = 3.8\times 10^{-12}\times 1.07\times 10^{15}\ decay/s = 4066 decay/s
