Answer:
Explanation:
Given that:
The heat of combustion of methylhydrazine =
It means that:
1 mole of methylhydrazine on combustion, releases of energy
Molar mass of methylhydrazine = 46.072 g/mol
Means that, 1 mole of methylhydrazine contains 46.072 g of methylhydrazine
Thus,
46.072 g of methylhydrazine on combustion, releases of energy
Also,
1 g of methylhydrazine on combustion, releases of energy
206.2 g of methylhydrazine on combustion, releases of energy
Heat released =
Answer:
75.2 degree Fahrenheit was the predicted high temperature.
Explanation:
Predicted high temperature in the Spain = T' = 24°C
In Spain temperatures are measured in Celsius. But we have to calculate the temperature in Fahrenheit .
To convert this temperature into Fahrenheit, we use the conversion factor:
75.2 degree Fahrenheit was the predicted high temperature.
Answer:
false
Explanation:
It is called the periodic table because of the way the elements are arranged. You'll notice they're in rows and columns. The horizontal rows (which go from left to right) are called 'periods' and the vertical columns (going from up to down) are called 'groups'.
Answer:
An atom can acquire a positive charge or a negative charge depending on whether the number of electrons in an atom is greater or less then the number of protons in the atom. When an atom is attracted to another atom because it has an unequal number of electrons and protons, the atom is called an ION.
