All alkail metals react with halogens vigorously to produce salt. The alkali metal would loose an electron to form and ion with the halogen
Answer:
The process of photosynthesis in plants releases oxygen into the atmosphere. Respiration by plants and animals, as they use the energy stored in food, and the process of decomposition of dead organisms, releases carbon dioxide into the atmosphere. All three work together to maintain the carbon dioxide-oxygen cycle.
Thats just a thought though.
To calculate an electron configuration, divide the periodic table into sections to represent the atomic orbitals, the regions where electrons are contained. Groups one and two are the s-block, three through 12 represent the d-block, 13 to 18 are the p-block and the two rows at the bottom are the f-block.
Answer : The for the combustion of naphthalene is
Solution : Given,
Mass of naphthalene = 1.025 g
Initial temperature =
Final temperature =
Specific heat capacity of calorimeter =
Molar mass of naphthalene = 128 g/mole
First, we have to calculate the heat absorbed,
Formula used :
Now put all the given values in this formula, we get
Now we have to calculate the moles of naphthalene.
Moles of =
Now we have to calculate the for combustion of naphthalene.
where,
q = heat absorbed
n = number of moles
Now put all the values in this formula, we get
Therefore, the for the combustion of naphthalene is
