11.9 if i read your question correctly sorry if it’s wrong lol
Missing question: <span>The decomposition of </span><span> XY is second order in </span><span>and has a rate constant of 6.96×10</span>⁻³ s⁻¹<span> at a certain temperature.
c</span>₀ = 0,050 M.
t = 55 s.
k = 6.96×10⁻³ s⁻¹.
Integrated second
order rate law is: 1/c₁ =
1/c₀<span> + k·t.
</span>1/c₁ = 1/0,050 M + 0,0069 s⁻¹ · 55 s.
1/c₁ = 20,38 1/M.
c₁ = 0,049 M.
Answer:
Yes is incorrect
Explanation:
not all veins carry blood rich in CO2 , the pulmonary vein carries blood with O2 which means that not all veins carry blood rich in CO2
The percent by mass : 6.3%
<h3>Further explanation</h3>
The concentration of a substance can be expressed in several quantities such as moles, percent (%) weight/volume,), molarity, molality, parts per million (ppm) or mole fraction. The concentration shows the amount of solute in a unit of the amount of solvent.
mass of potassium nitrate = 8.4 g⇒solute
- mass of solution = mass of solute+mass of solvent(water)
mass of potassium nitrate + mass of water = 8.4 g + 125 g =133.4 g
Percent by mass of the solute :
Answer: controller.
Justification:
A fission reaction is the split of the nucleus of an atom due to the bombardment with neutrons.
A fission reaction may terminate in a reaction chain, a controlled reaction or extinguish.
When for every 2 or 3 neutrons released, only one neutron is allowed to strike a fissionable nucleus, the reaction is controlled.
When the the ratio is less than one then the reaction will be extinguished.
When the number of reactions grow, this is a reaction chain, where the reaction is out of control, and the consequence is the release of vast amount of energy (heat) is a short time, causing a nuclear explosion.
