6. What is the equilibrium constant for the following reaction?<br> C+02 = CO2
Orlov [11]
<h3>\tt Kc=\dfrac{[CO_2]}{[C][O_2]}</h3><h3>Further explanation</h3>

Given

Reaction

C+02 = CO2

Required

The equilibrium constant

Solution

The equilibrium constant is the ratio of concentration or pressure between the product and the reactant with each reaction coefficient raised  

The equilibrium constant is based on the concentration (Kc) in a reaction  

pA + qB -----> mC + nD  

\large {\boxed {\bold {Kc ~ = ~ \frac {[C] ^ m [D] ^ n} {[A] ^ p [B] ^ q}}}}

So for the reaction :

C+O₂ ⇔ CO₂

\tt Kc=\dfrac{[CO_2]}{[C][O_2]}

If the partial pressure of oxygen outside of a cell is 100 mmHg and the partial pressure of oxygen inside of a cell is 25 mmHg,
mrs_skeptik [129]

" There will be a net movement of oxygen from outside the cell to inside the cell " Statement is True.

Explanation:

The partial pressure for oxygen in alveoli is greater under normal circumstances, and oxygen moves neatly into the blood. In addition, the partial carbon dioxide pressure throughout the blood usually is higher, such that carbon dioxide migrate clearly into the alveoli.

The few common molecules which can traverse the cell membrane by absorption (or diffusion of a sort recognized as osmosis) are water, carbon dioxide and oxygen. Metabolism is typically oxygen-needed, which is lowest in the cell within the animal and plant, so that net oxygen flows to the cell.

Convert 32.56 km/hr into ft/hr
Gekata [30.6K]
Note that
1 m = 3.2808 ft

Therefore
1 km = 3280.8 ft
and
32.56 \,  \frac{km}{h} = (32.56 \,  \frac{km}{h})*(3280.8 \,  \frac{ft}{km}) =  1.0682 \, \times 10^{5} \, \frac{ft}{h}

Answer: 1.0682 x 10⁵ ft/hr

Before the battery in the car is jumped, the individuals notice the hook-ups on the battery are corroded by acid. what substance
Vilka [71]

Answer:

Baking soda

Explanation:

Due to its neutralizing properties, sodium bicarbonate can be used to counteract the acid corrosion of car batteries. To use baking soda, in this case, be sure to disconnect the battery terminals before cleaning. Make a paste of three parts baking soda to one part water and apply with a damp cloth to rub the corrosion of the battery terminal. After cleaning and reconnecting the terminals, clean them with petroleum jelly to prevent future corrosion.
