Answer:
Empirical formulas show the simplest whole-number ratio of atoms in a compound, molecular formulas show the number of each type of atom in a molecule, and structural formulas show how the atoms in a molecule are bonded to each other.

HEY PLS DON'T JOIN THE ZOOM CALL OF A PERSON WHO'S ID IS 825 338 1513 (I'M NOT SAYING THE PASSWORD) HE IS A CHILD PREDATOR AND A PERV. HE HAS LOTS OF ACCOUNTS ON BRAINLY BUT HIS ZOOM NAME IS MYSTERIOUS MEN. HE ASKS FOR GIRLS TO SHOW THEIR BODIES AND -------- PLEASE REPORT HIM IF YOU SEE A QUESTION LIKE THAT. WE NEED TO TAKE HIM DOWN!!! PLS COPY AND PASTE THIS TO OTHER COMMENT SECTIONS!! YOU CAN ALSO PUT IT AS A QUESTION< THIS IS NOT A JOKE THIS IS SOMETHING VERY SEROUIS AND DANGEROUS AND SHOULD BE TAKEN VERY SEROUISLY
Explanation:
A collision in which some part of a kinetic energy is changed into another form of energy is known as an inelastic collision.
In an inelastic collision momentum is conserved because total momentum of both the objects before and after the collision are same.
Whereas kinetic energy during this collision is not conserved because a part of kinetic energy changes into heat, sound and deformation of objects.
Thus, we can conclude that during an inelastic collision, the total momentum of the system is conserved, while kinetic energy is not conserved.
Answer:
Explanation: tellurium has an atomic mass of 127.6 whilst the element that comes after it, iodine, is lighter with an atomic weight of 126.9. Mendeleev concluded that the atomic mass for one of these two elements must be wrong because tellurium clearly preceded iodine in the periodic table
Answer:
The freezing point will be -2.046°C.
Explanation:
The freezing point depression equation is
Where;
= The temperature depression of the freezing point
= The constant of freezing point depression which is solvent dependent = 1.86°C/m
i = The number of particles the substance decomposes into in solution = 1 for sugar (a covalent compound)
m = The molality of the solution = 1.1
Therefore, we have;
Therefore the freezing point will be 0 - 2.046°C = -2.046°C.
