A clay ball (50 degrees Fahrenheit) is placed in a bucket of water (80 degrees Fahrenheit.) which scenario describes how heat en

ergy is transferred between the ball and water?
a.) heat energy is transferred from the ball to the water until they are both at 65 degrees Fahrenheit.

b.) heat energy is transferred from the water to the ball until they are both at 65 degrees Fahrenheit.

c.) heat energy is transferred from the water to the ball until the ball is at 80 degrees Fahrenheit and the water is at 50 degrees Fahrenheit.

d.) no heat energy would be transferred between the ball and the water, so the ball will stay at 50 degrees Fahrenheit and the water will stay at 80 degrees Fahrenheit.

2. What are the characteristics of an acid (at least 3)?
arlik [135]

Answer:Acids taste sour, react with metals, react with carbonates, and turn blue litmus paper red. Bases taste bitter, feel slippery, do not react with carbonates and turn red litmus paper blue.

Explanation:

  • Sour taste (though you should never use this characteristic to identify an acid in the lab)
  • Reacts with a metal to form hydrogen gas.
  • Increases the H+ concentration in water.

each of the following reactions has been reported in the chemical literature. predict the product in each case, showing stereoch
poizon [28]

(a): This is an elimination reaction. The reaction proceeds in 3 steps; Step 1: Protonation of alcohol, step 2: Loss of leaving group, and step 3: Deprotonation to form an alkene. Elimination (E1) reaction dominates than substitution (SN1) reaction because the formed HSO4- anion is a poor nucleophile and tends not to add to the carbocation intermediate formed. Hence the product formed is I, is trans.

(b) This is a dihydroxylation of the alkenes reaction. A catalytic amount of OsO4 is used along with an oxidizing agent, which oxidizes the reduced osmium(VI) into osmium(VIII) to regenerate the catalyst. The reaction proceeds in 2 steps; Step 1: Cis addition of OsO4 to double bond and form 4 member cyclic osmate ester. Step 2: Hydrolysis of the intermediate to 1.2-diol. Hence the product formed is II, is cis. 

(c) This is hydroboration - oxidation reaction. The reaction proceeds through the addition of H- on the more substituted carbon and BH2 on the less substituted carbon of the double bond. The reaction is a syn addition. Hence the product formed is III.

(d) This a reduction reaction where carboxylic acid (-COOH) is reduced to 1o alcohol (-CH2OH). Hence the formed product is IV.

Stereochemistry, a subdiscipline of chemistry, involves the take a look at the relative spatial association of atoms that form the shape of molecules and their manipulation.

The observation of stereochemistry specializes in stereoisomers, which by means of definition have an equal molecular method and series of bonded atoms (constitution), however, differ within the three-dimensional orientations of their atoms in space. for that reason, it's also referred to as 3-d chemistry three-dimensionality.

How do we differentiate chemical change from physical change ​
bija089 [108]

Answer:

Chemical change :has change in mass, heat is needed, new element is formed, hard to reverse.......

Physicalchange:does not have change in mass, heat is not necessary, no new element is formed, easy to reverse
