What is the melting point of calcium chloride?
The melting point depends on the number of water molecules (x) in CaCl2.xH2O 772 °C (anhydrous) (x = 0) 260 °C (monohydrate) (x = 1) 176 °C (dihydrate) (x = 2) 45.5 °C (tetrahydrate) (x = 4) 30 °C (hexahydrate) (x = 6)
How long does calcium carbonate take to thermally decompose?
Calcium carbonate typically decomposes when heated to form calcium oxide and carbon dioxide. This decomposition process usually takes place over a temperature range of 825-900 degrees Celsius and can vary in duration depending on factors like the heating rate and the particle size of the calcium carbonate.
What does 825 Cz mean on a ring?
825 Cz likely refers to the metal composition of the ring. In this case, 825 indicates a silver content of 82.5%, and Cz could stand for cubic zirconia, a type of synthetic gemstone often used as a diamond substitute in jewelry.
What does 825 cl mean on a gold colored ring?
"825 CL" likely refers to the purity of the metal. In this case, the ring is most likely made of gold that is 82.5% pure, which is commonly referred to as 825 parts per thousand gold. This indicates that the ring is gold-plated or gold-filled rather than solid gold.
Gas stored in a tank at 273 K has a pressure of 388 kPa. The safe limit for the pressure is 825 kPa. At what temperature will the gas reach this pressure?
Using the combined gas law (P1/T1 = P2/T2), we can calculate the new temperature at the safe limit pressure: (388 kPa / 273 K) = (825 kPa / T2) T2 = 273 K * (825 kPa / 388 kPa) T2 = 578 K Therefore, the gas will reach a pressure of 825 kPa at a temperature of 578 K.
If Lead melts at 601.0 degrees celsius what temperature is this in Fahrenheit?
The melting point of lead in Celsius is 327.46o. Temperature Fahrenheit = Temperature Celsius(1.80) + 32 Temperature Fahrenheit = (327.46o C)(1.80) + 32 = 621.43o Fahrenheit ==============
What does 825 equal as a fraction?
825 as a fraction = 825/1
What is Limestones melting point?
The melting point of limestone (calcium carbonate) is approximately 1,339 degrees Celsius (2,442 degrees Fahrenheit). At this temperature, limestone decomposes to form lime (calcium oxide) and carbon dioxide gas.
What is .825 as a degrees?
47.269 degrees.
What are two numbers that are equal to 825?
Two numbers that are equal to 825 could be 825 itself and 0 + 825. Another example could be 1650 divided by 2, as both yield 825.
What 2 numbers are equal to 825?
825.0 and 825/1 are both equivalent to 825
What is the melting point of shells?
The melting point of shells varies depending on their composition, primarily calcium carbonate in many marine shells. Typically, calcium carbonate starts to decompose rather than melt at temperatures around 825 degrees Celsius (1,517 degrees Fahrenheit). However, shells are not commonly melted in practice; they can be crushed or dissolved in acids instead.
825 feet equals how many yards?
One yard is equal to 3 feet. Therefore, 825 feet is equal to 825 / 3 = 275 yards.
What does 825 equal as a percent?
825 = 82,500% (multiply a number by 100 to get its value as a percent).
What is the answer to 11x75?
11x75 is equal to 825.
What is 825 times 52 equal?
42900
How many 825 degrees F equals how many degrees Celsius?
440.6 rounded up. The formula for F to C is (F-32) x 5/9=C, and to convert from C to F, (C x 9/5) +32=F
