The answer is rings, I know this because i took a test about it and I got it right
A rock is obviously more dense than a crumpled piece of paper of the same size. A styrofoam cup is less dense than a ceramic cup.
hope this helps if it do mark me as brainlest thank you !!
Answer:propanoic acid
Explanation:
Carboxylic acids contain the COOH group. This group is capable of hydrogen bonding leading to association of the molecules. Cyclobutane is a cyclic alkane and acetone is a ketone. Non of these compounds posses a polar -OH bond which is necessary for the occurrence of hydrogen bond. Hydrogen bonds only occur in carboxylic acids and alcohols. Hydrogen bond leads to molecular association and high boiling points.
Answer: The rate of the reaction decrease over time as the reaction proceeds, a decrease in the concentration of reactants results in fewer successful collisions.
Explanation:
Rate of a reaction is defined as the change in concentration of products and reactants with respect to time.
The rate of a reaction decreases with times because reactants are converting into products.
As a result, the reaction is proceeding with a decrease in the concentration of reactants due to which less number of collisions between the reactant molecules will be there.
Hence, rate of reaction will decrease.
Thus, we can conclude that the rate of the reaction decrease over time as the reaction proceeds, a decrease in the concentration of reactants results in fewer successful collisions.
