Hello!
The set of compounds that have the same empirical formula is b) N₂O₄ and NO₂.
The Empirical Formula is the most simple representation of the atom ratio in a chemical compound. Of the listed sets of compounds, the only in which the atom ratio is the same for both compounds is the pair N₂O₄ and NO₂ in which the atom ratio N:O is 1:2. The Empirical Formula for this pair is NO₂.
N₂O₄ has the same atom ratio as NO₂ but this formula has each atom multiplied by two. However, its Empirical Formula is the same.
Have a nice day!
Answer:
Neil's Bohr improved Rutherford's model.
Explanation: I hope this helps! :)
Answer:
The correct answer is option C. "the rate increase! by a factor of 2".
Explanation:
The rate of a typical chemistry reaction is positively affected by the concentration of the substrate. Where the more concentrated the substrates are, the faster the reaction occurs. In this case, doubling the concentration of sodium acetate will double the rate of the reaction, since sodium acetate have a positive effect in the reaction by acting as a substrate along with bromoethane.
A chemical reaction (signs)
- rusting
- change in base of chemical
- for example lets say u mix two chemicals, and then it becomes a different new chemical (it changed from the inside)
a physical
- a physical reaction is outer looks not inside.
- it changes on the outside, like changing a color
