Answer:
Explanation:
The equation of the reaction:
Nitrogen gas N₂ reacts with Hydrogen as H₂ to produce ammonia NH₃;
N₂ + H₂ → NH₃
The balanced equation is ;
N₂ + 3H₂ → 2NH₃
The mole ratio is the ratio of the coefficients of the combining reactants;
1 mole of N₂ combines with 3 mole of H₂;
So;
<h2>Answer:</h2>
Scientific questions are question which are solved involving experiments, observations, or surveys.
Like, Is cancer caused by uncontrolled cell division.
<h3>Explanation:</h3>
Scientific questions are always testable questions. They can be solved by using scientific techniques like PCR, titration etc.
Here the given question in the example can be tested, by making the observations of the cell division of the cancer patients. Then by inducing uncontrolled cell division into normal cells to look for the effect of cell division on cancer.
The questions like, "is sadness can be controlled by talking?" is not a scientific question.
Answer and Explanation:
The working-energy theorem defines work as the energy change brought on by the velocity change. The environment has acted on the object and it increases the energy of the object. When an object's velocity decreases, the object has worked on the world, and the object's energy decreases.
Unless the displacement is in the reverse direction and the force applied, then the work performed is negative. If the displacement is in the same direction and the force applied, then the work performed is positive.
Use M1V1 = M2V2
11.9(8) = 1.5V2
95.2 = 1.5(V2)
V2 = 63.5 mL
