Can a graph have a euler circuit but not a hamiltonian circuit?
Yes. Example: .................................................... ...A * ........................................... ......|.\ ......................................... eg Euler circuit: ACDCBA ......|...\ ........... --------- ............. ......|.....\........./...............\............ The Hamilton circuit is impossible as it has two ......|.......\...../...................\.......... halves (ACD & CD) connected to each other only ......|.........\./.......................\........ at vertex C. Once vertex C has been reached in ......|.......C *........................* D.... one half, it can only be used to start a path in ......|........./.\......................./......... the other half, or complete the cycle in the ......|......./.....\.................../........... current half; or if the path starts at C, it will end ......|...../.........\.............../............. without the other half being visited before C is ......|.../ ........... --------- .............. revisited. ......|./ ........................................... ...B *.............................................. ......................................................
What dose kcl stand for?
kcl does not stand for anything. For a chemical element or compound it is very important to ensure that the upper and lower case letters are used properly. For example, CO is carbon monoxide but Co is cobalt.KCl (upper case K and C, and lower case l) stands for potassium chloride.
What is the molality of a solution of water and KCl if the freezing point of the solution is and ndash3 and degC (Kf 1.86 and degCm molar mass of water 18 g)?
To find the molality of the KCl solution, we can use the freezing point depression formula: ΔTf = Kf * m * i, where ΔTf is the change in freezing point, Kf is the cryoscopic constant (1.86 °C kg/mol for water), m is the molality, and i is the van 't Hoff factor (which is 2 for KCl, as it dissociates into K⁺ and Cl⁻). The change in freezing point is 0 - (-3) = 3 °C. Rearranging the formula gives us m = ΔTf / (Kf * i), so m = 3 / (1.86 * 2) ≈ 0.806 mol/kg. Therefore, the molality of the KCl solution is approximately 0.806 mol/kg.
Why aren't you supposed to touch an electrocuted person before you disconnect the circuit?
B/c that can make you part of the circuit, electrocuting yourself too.
What is a Circuit breaker and explain type circuit breakers?
A circuit breaker is a switching device which can make,brake and carrying (or trip the circuit) that specified over currents for a small interval of time . There is a different types of Circuit Breaker's are there 1.According to their arc quenching media these are divided into 4 types a) Oil circuit breaker b) Air blast circuit breaker c) SF6 circuit breaker d) vacuum circuit breaker 2. According to their services the circuit breaker can be divided as a) Outdoor Circuit Breaker b) Indoor Breaker 3. According to the operating mechanism of circuit breaker they can be divided as a) Spring operated Circuit Breaker b) Pneumatic Circuit Breaker c) Hydrolic Circuit Breaker 4. According to the voltage level of installation these are divided into 3 types a) High Voltage Circuit Breaker b) Medium Voltage Circuit Breaker c) Low Voltage Circuit Breaker.
Which potassium salt is the least soluble at 40 C and at 80 C KBr or KCl?
At 40°C, KBr is less soluble than KCl. At 80°C, the trend may reverse, with KCl possibly being less soluble than KBr. The solubility of salts typically increases with temperature, so KBr may be the least soluble at both 40°C and 80°C.
How many grams of kcl can dissolve in 100g of water at 30C?
Approximately 34 grams of KCl can dissolve in 100g of water at 30°C.
What mass of KCl would be needed to form a saturated solution if the KCl was dissolved in 200 g of water at 80 C?
The solubility of KCl in water at 80°C is approximately 380 g/L. To form a saturated solution, you would need to dissolve 380 g of KCl in 1 L (1000 g) of water. Since you are using 200 g of water, you would need 76 g of KCl to form a saturated solution.
When 5 grams of KCl are dissolved in 50. grams of water at 25C the resulting mixture can be described as?
This is a solution of 10 g KCl/100 g water.
Solubility of KCl at 100 degrees C?
The solubility of KCl at 100 degrees Celsius is approximately 56.5 g/100 mL of water. This means that at this temperature, 100 mL of water can dissolve 56.5 grams of KCl before reaching saturation.
How many grams of KCl can dissolve in 100 g of water at 80C?
Approximately 42 grams of KCl can dissolve in 100 grams of water at 80°C.
What is the pH KCl?
1. Identify (a) through (d) as reactants or products. Type your answers in the spaces provided: (a) (b) (c) (d) KOH + HCl KCl + H2O
What is the value of specific conductance of 0.1 N KCl?
The specific conductance of 0.1 N KCl solution is approximately 1.25 mS/cm at 25°C.
What is the vapor pressure of KCl?
The vapor pressure of KCl depends on temperature. At room temperature (around 25°C), the vapor pressure of KCl is very low, close to negligible. As the temperature increases, the vapor pressure of KCl also increases, following the general trend for solids.
What is vat rates when selling goods from Maharashtra to Haryana?
Vat is not applicable. because it is a interstate sale. so only cst is applicable . cst 2%. along with form 'c'...if form 'c' is not provided by the buyer, then state vat is applicable...
What is the melting point of KCL?
K2CO3 is the molecular formula for potassium carbonate. K2CO3 has a melting point of 1164 degrees Kelvin and is 138.21 grams per mole.
What is the molar conductivity of kcl in infinit dilution?
Infinite dilution molar conductivity is the limiting value of the molar conductivity as the concentration tends to zero. The molar conductivity of KCl at infinite dilution is approximately 149.9 S cm² mol⁻¹ at 25°C.
