Answer:
They are all located in the same horizontal row or period.
Explanation:
In the periodic table the elements are arranged according to their increasing atomic number.The elements those contain low atomic number are placed in the first row such as hydrogen and helium. similarly the radioactive elements those have high atomic number are placed in 7th or 8th row.
All the elements of a family in the peroidic table have common features are located in same horizontal row or period.For example fluorine,chlorine,bromine and iodine are placed in VII B class of periodic table as all of them are electronegative in nature.
Answer:
1,100,160J or 262.94 kcal
Explanation:
The juice is frozen at 0 degrees Celsius and I assume that it will become gas at 100 degrees Celsius. So we change the form of the water from solid to liquid, then to gas. That means we have to find out how much heat needed to change water form too, not only the heat needed to increase its temperature.
The latent heat of water is 4.2J/g °C while the heat of fusion is 334 J/g and the heat of vaporization is 2260 J/g. The energy needed will be:
360g * 4.2J/g °C * (110-0°C ) + 360g * 334 J/g + 360g * 2260 /g = 1,100,160J or 262.94 kcal.
Answer:
Carbon tends to bond covalently with Hydrogen
I would sort them like animals one pale and humans 2nd pale. Ionk
The molar mass of a 0.314-gram sample of gas having a volume of 1.6 l at 287 k and 0.92 atm. is 5.23 gram.
<h3>What is an Ideal Gas ?</h3>
An Ideal Gas is a law for ideal gas which states that the product of Pressure and Volume is equal to the product of the moles of sample, universal gas constant and temperature.
PV = nRT
The given data in the question is
Pressure = 0.92 atm
Volume = 1.6 l
Temperature = 287 K
0.92 * 1.6 = n * 287 * 0.082
n = 0.06 moles
0.06 = 0.314 / molecular weight
molecular weight = 0.314/0.06
Molecular weight = 5.23 gm
Molar mass = 5.23 gm.
The temperature and pressure conditions at which the gas behaves like an ideal gas is 273 K and 1 atm.
