What else can I help you with?
2H2O 2H2 O2?
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.
Is it true that a low concentration of a chemical slows reaction rate?
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 a control for the experiment described in the question below?
Which of the following is not true about controls in an experiment
What two things are always true of a number written in scientific notation?
The exponents can be plus or minus.
Temperature below freezing means snow?
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 .
Which of the following is true for the gas phase reaction shown below 2c2ho g 5o2 g 4co2 g 2h2o g Δh 2511 kj?
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.
Which of the following is true for the gas phase reaction shown below 2c2h2 g plus 5o2 g 4co2 g plus 2h2o g Δh equals -2511 kj?
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.
The polynomial below is a perfect square trinomial of the form A2 - 2AB plus B2 4x2-16x plus 16?
True
Which of the following is true for the gas phase reaction shown below 2NH3g N2g plus 3H2g ΔH equals 160.58 kJ?
ΔS is positive and ΔG is negative at low temperatures only
The expression below is a sum of cubes 64x3 plus 125?
true
Which of the following is true for the gas phase reaction shown below 4nh3 g plus 5o2 g 4no g plus 6h2o g Δh equals 0.905 kj?
s is positive and g i s negative at all temperatures
The polynomial below is a perfect square trinomial of the form A2 - 2AB plus B2 9x2-18x plus 36?
TrUE
Which of the following is true for the gas phase reaction shown below 4nh3g plus 5o2g 4nog plus 6h2og Δh equals -0.905 kj?
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.
What is the reaction involving the Burning of Hydrogen?
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
What is true for the gas phase reaction shown below 2NH3 gives n2 plus 3h2 delta H equals 160.58 kj?
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 pcl3 g plus cl2 g pcl5 g has keq equals 300 at a certain temperature if pcl3 equals 0.15 cl2 equals 0.04 and pcl5 equals 1.5 what is true about this reaction?
The reaction will proceed to the right. 2 PCl3 will be consumed.
What is th balanced equation between magnesium chloride plus sulfuric acid?
A true reaction don't exist between magnesium chloride and sulfuric acid.
