An ant carries a morsel of food 4.26 meters along a straight path to his nest. he then turns around and follows the path back to
SVEN [57.7K]
<span>Answer: 0.00 meters

  Solution:

    Step 1: Define displacement DISPLACEMENT = a vector quantity that describes "linear or angular distance in a given direction between a body or point and a reference position."

  Step 2: Understand the question

 Assumption 1: Assume that when the ant moves 4.25 meters from its origin to its nest, it is moving in a positive direction (on a graph you would draw a line along the x-axis from its origin to +4.25).

  Assumption 2: Assume that when the ant "turns around...back to the source of food", it is moving back in the negative direction (towards the origin).

   Step 3: Analyze the question

  What is the distance between where the ant originally started and where it ended its journey?

  The ant started and ended its journey in the same place.

 While it traveled a distance of 8.52 meters (2 * 4.26 = 8.52), it's displacement is actually 0.00 meters (4.26 + (-4.26) = 0.00)

  Therefore, the answer is 0.00 meters</span>

Propanoic acid, ch3ch2cooh, has a pka =4.9. draw the structure of the conjugate base of propanoic acid and give the ph above whi
xenn [34]

Conjugate base of Propanoic acid (CH_{3}CH_{2}COOH is propanoate where -COOH group gets converted to -COO^{1-}. The structure of conjugate base of Propanoic acid is shown in the diagram.

The p^{H} above which 90% of the compound will be in this conjugate base form can be determined using Henderson's equation as propanoic acid is weak acid and it can form buffer solution on reaction with strong base.

p^{H}= p^{k_{a}+ log\frac{[Conjugate base]}{[acid]}=4.9+log\frac{90}{10}=5.85

As 90% conjugate base is present, so propanoic acid present 10%.

A model of an atom shows eight electrons in rings that represent different energy levels. How many electrons are in each energy
Scilla [17]

Answer:

The correct option is;

C. Two in the first energy level, six in the second energy level

Explanation:

The electrons in an atom are arrange in orbital shells which are situated at different levels within the structure of the, depending on the energy of the electron. Electrons with the least amount of energy are found in the shell closest to the nucleus of the atom which is the first energy level

The maximum number of electrons that can be found in a given an energy level is obtained with the following formula;

The number of electron = 2 × n²

Where;

n = The number of the different energy level

Therefore;

The maximum number of electrons in the first energy where n = 1 is given as follows;

The number of electron = 2 × 1² = 2 electrons

The maximum number of electrons in the second energy level where n = 2 is given as follows;

The number of electron = 2 × 2² = 8 electrons

Given that there are only 8 electrons in the atom, we therefore have, 2 electrons in the first energy level and the remaining 8 - 2 = 6 electrons in the second energy level.
