I think you've answered your own question. 2H2 plus 02 forms 2H20.Yes, but perhaps he doesn't know the product is the part on the right side of the arrow. In this case, as you said, 2H2O.
I would point your studies towards collision theory. It's not that a low concentration necessarily slows down a reaction, but that a low concentration will have a slower reaction rate than a higher concentration of reactants. A lower concentration means a lower number of reactants in solution, meaning it is less likely for the reactants to collide and create products. With a lot of reactants, it is much more likely for collisions to occur.
Which of the following is not true about controls in an experiment
The exponents can be plus or minus.
Snow does occur when temperature is below freezing because snow is just frozen rain . Lets say it rains , and the temperature is below freezing , that rain would become snow . So temperature below freezing means having snow is true .
ΔS is positive and G is negative at all temp.Which of the following is true for the gas phase reaction shown below? 2C2H2(g) + 5O2(g) → 4CO2(g) + 2H2O(g), ΔH = -2511 kJΔS is negative and ΔG is negative at low temperatures.
The given reaction is the combustion of acetylene (C2H2) in oxygen (O2) to form carbon dioxide (CO2) and water (H2O). The negative enthalpy change (-2511 kJ) indicates that the reaction is exothermic, meaning it releases heat energy to the surroundings. This reaction is highly favorable in the gas phase due to the large negative enthalpy change.
True
ΔS is positive and ΔG is negative at low temperatures only
true
s is positive and g i s negative at all temperatures
TrUE
The reaction is exothermic because the enthalpy change (ΔH) is negative (-0.905 kJ). This means heat is released during the reaction. The reaction forms nitrogen monoxide (NO) and water (H2O) from ammonia (NH3) and oxygen (O2) in the gas phase.
When you burn Hydrogen and Oxygen You end up with a water molecule that has an extra oxygen atom ~This is true, but H2O2, hydrogen peroxide is relatively unstable. When hydrogen gas is burned in the presence of oxygen, it is mostly to yield water and oxygen. 2H2 +2O2 → 2H2O + O2
The reaction is the decomposition of ammonia gas into nitrogen gas and hydrogen gas. The reaction is endothermic, as indicated by the positive value of ΔH (160.58 kJ). This means that heat is absorbed from the surroundings for the reaction to occur.
The reaction will proceed to the right. 2 PCl3 will be consumed.
A true reaction don't exist between magnesium chloride and sulfuric acid.
