Answer:
Explanation:
Hello,
In this case, the combustion of octane is chemically expressed by:
In such a way, due to the 25/2:8 molar ratio between oxygen and carbon dioxide, we can compute the yielded grams of carbon dioxide (molar mass 44 g/mol) as shown below:
Best regards.
The rows are the one line of elements that goes from left to right horizontally. A column is a line of elements that goes vertically.
Answer : If a substance is covalent, then it is likely to melt easily and fast, it may be composed of two or more non-metals which share a covalent bonding between them and it will not conduct electricity.
It is seen that covalent substances are made up of two or more non-metals which share a covalent bond between them. They are found to melt easily and when dissolved in water they are seen to be insoluble. They are also not good conductors of electricity as there is no free electron available to conduct electricity.
To find how many moles of the gas you can use ideal gas formula. Remember to change the temperature unit to Kelvin. Since the pressure using kpa, the constant used would be 8.314 kpa*L / mol*K
PV=nRT
n= PV/RT
n= 17,250 kpa * 20 / 8.314 * (24+273.15)K
n=139.64moles
Glaciers are found in areas where the net accumulation of snow exceeds the melt, therefore they are usually found in areas of high elevation, cold temperatures, and high precipitation.
Geysers are found in areas of shallow crust with high heat flow, such as hot spots.
