Answer:
substances is never entirely a one way
Explanation:
no possibility of obtaining complete combustion at hig
temperature.
always loss of heat from the temperature
its temperature is lower than the constant volume process because some of the energy is utilized to change the volume of the system
Answer:
Explanation:
The answer is 9.03 × 10²⁴ molecules.
Avogadro's number is the number of units (atoms, molecules) in 1 mole of substance.
Make the proportion.
6.02 × 10²³ molecules per 1 mol
x per 15 mol
6.02 × 10²³ molecules : 1 mol = x : 15 mol
x = 6.02 × 10²³ molecules * 15 mol * 1 mol
x = 90.3 × 10²³ molecules
x = 9.03 × 10 × 10²³ molecules
x = 9.03 × 10²³⁺¹ molecules
x = 9.03 × 10²⁴ molecules
Boron trichloride has a simple molecular structure,
whereas sodium chloride has a giant ionic lattice
structure. The ionic bonding between oppositely
charged ions in NaCl is stronger than the covalent
intramolecular bonding in BCl3. Therefore, less energy
is required to break the intramolecular covalent bonds in
BCl3, hence a lower melting temperature.
The answer is nuclear fission. They use nuclear fission in the core of a nuclear reactor to heat up the water and the water from the core will be passed down to the heat exchanger and heat up other water sources. The water will be steamed and its steam will be converted into electricity.
