What are the phases for 2Na plus F2 equals 2NaF?
In the reaction 2Na + F2 → 2NaF, sodium (Na) is in the solid phase, while fluorine (F2) is in the gaseous phase. The product, sodium fluoride (NaF), is formed as a solid. Thus, the phases for the reactants and products are: 2Na(s) + F2(g) → 2NaF(s).
Phase shift of y equals sin x-2?
Shift = +2
What are the two faces of photosynthesis?
light face and dark face.Actually it is phase not face. They are light reaction and dark reatcion
Which is greater 1kw equals equals KVA?
In the case of DC, and in AC when current and voltage are in phase, a volt-ampere is the same as a watt (and therefore, a kilo-volt-ampere is the same as a kW). In the case of AC, when current and voltage are NOT in phase, power = voltage x current x power factor; the power factor is the cosine of the angle between current and voltage, and it is always less than or equal to one. In such a case, a kVA would be less than a kW.
What is meant by space vector modulation?
Space-vector (pulse width) modulation technique is a PWM technique for three-phase voltage-source inverters. Read the white paper I linked below, or the app note that I also linked below. Interested in the real nitty gritty? Try the PhD Thesis that I linked below.
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
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.
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.
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.
What is the primary reaction in photosynthesis?
It is the first phase. The light dependent reaction.
What is peritectic reaction?
Peritectic reaction is a reaction in which two phases (solid and a primary solid phase alpha) in converted into a single phase beta. Differs from eutectic reaction. Unlike eutectic reaction in which a single phase (liquid) is transformed into two solid phases. For eutectic reaction the Eutectic point is the common melting point which is lower than melting points of both individual melting points. This is not true with peritectic reaction.
What happens during dark reaction phase and light reaction phase in photosynthesis?
In the light reaction phase of photosynthesis, light energy is converted into chemical energy in the form of ATP and NADPH. These energy carriers are then used in the dark reaction phase, also known as the Calvin Cycle, to convert carbon dioxide into glucose. The dark reaction does not require direct light and takes place in the stroma of the chloroplast.
A reaction in which all the reactants and the product in the same phase?
A homogeneous reaction is one in which all reactants and products are in the same phase (e.g., gas, liquid, or solid). This type of reaction is characterized by uniform concentration and temperature throughout the reaction mixture. Examples include aqueous reactions in liquid phase and combustion reactions in gas phase.
What do you call a reaction when it cancels out?
Phase cancelation
What conditions would pressure affect the reaction rate?
If the reaction occurs in the gas phase
Where is most of the water produced in this reaction?
In this reaction, most of the water is produced in the liquid phase.
