Answer:
large intestine is right below the stomach and gallbladder and has the small intestine in the middle
works mainly with the digestive system
The large intestine gets rid of the undigested food that the small intestine could not absorb and reabsorbs water from the digestion
other organs include:
pancreas
small intestine
gallbladder
liver
stomach
esophagus
salivary glands
the function of the large intestine is to get rid of waste, absorb water, and absorb any nutrients which did not get absorbed in the small intestine
Explanation:
The mass percent of each compound is
- (NaBr*2H2O)=85.71 percent
- (MgBr2*6H2O)=14.29 percent
<h3>The mass percent equation is as follows.</h3>
The formula mass percent is the most effective way to express mass percent: mass percent = (mass of chemical x total mass of compound) times 100. Add 100 to the top value to get the value expressed as a percentage.
<h3>What percentage by mass does a solution have?</h3>
By multiply the grams of solute per gram of solution by 100, it is possible to get the mass percent of a solution.
The molar mass of each element and the mass of each element contained in a mole of the compound are both solved for in the Mass Percent formula.

Reconstitution is the act of adding fluid such as distilled water to a powdered or crystalline form.
Additionally, medications are frequently provided in dry form, such as powders or crystals, which must be reconstituted with liquid before being injected parenterally. To create a specified liquid concentration, a dry ingredient is reconstituted by adding a liquid diluent. To ensure that the drug is reconstituted in the exact concentration, it is crucial to carefully follow the reconstitution instructions. The quantity of fluid used to dilute the drug must also be taken into account when determining the dosage of reconstituted medication to provide to the patient.

Answer:
Explanation:
Ba(s) + Mn²⁺ (aq,1M) → Ba²⁺ (aq,1M) + Mn(s)
Ba⁺²(aq) +2e → Ba(s) , E° = −2.90 V
Mn⁺²(aq) +2e → Mn(s), E⁰ =0.80 V
Anode reaction :
Ba(s) → Ba⁺²(aq) +2e E° = −2.90 V
Cathode reaction :
Mn⁺²(aq) +2e → Mn(s) E⁰ =0.80 V
Cell potential = Ecathode - Eanode
Ecell = .80 - ( - 2.90 )
Ecell = 3.7 V .
equilibrium constant ( K ) :
Ecell = .059 log K / n
n = 2
3.7 = .059 log K / 2
log K = 125.42
K = 2.63 x 10¹²⁵ .
Free energy change :
ΔG = - n F Ecell
= - 2 x 96500 x 3.7
= 714100 J
= 7.141 x 10⁵ J .
The relation between activation energy, rate constant and temperature is given by Arrhenius equation
Arrhenius equation is
ln (K2/ K1) = Ea / R (1/T1- 1/T2)
K2 = 1×10−3s−1 T2 = 525 ∘C = 798 K
K1 = 1×10−4s−1 T1 = 485 ∘c = 758 K
Ea = ?
R = gas constant = 8.314 J / mol K
ln (K2/ K1) = ln (10^-3 / 10^-4) = 2.303 = Ea /8 .314 (1/758 - 1 / 798)
2.303 = Ea / 8.314 (0.00132 - 0.00125)
Ea = 2.303 X 8.314 / (0.00132 - 0.00125) = 273530.6 J / mole
Ea = activation energy = 273.531 kJ / mole
