Bird, Tiger, and the Leech


1.) Movement

All living things move in some way. This may be obvious, such as Tigers are able to walk, or less obvious, such as plants that have parts that move to track the movement of the sun.

Leeches use circular and longitudinal muscles to move along

2.) Growth

All living things grow. For example the Blue Jay (bird) pictured above started out as an egg and developed into a bird

3.) Excretion

No matter what living thing it is, everything gives off waste. For example a leeche poops out it’s unneeded “nutrients”

Give the hybridization for the c in hcch. group of answer choices
Tamiku [17]

The hybridization for C in acetylene, HCCH, or C₂H₂ is 'sp'.

Discussion:

There are three different forms of hybridization -

  1. sp- The first occurs when two carbon atoms are triple linked.
  2. sp₂- When two carbon atoms are double-bonded to one another, this is known as sp₂.
  3. sp₃- When a single bond joins two carbon atoms, this is known as sp₃.

In the case of acetylene(HCCH or C₂H₂):

  • The carbon atom requires additional electrons to establish four bonds with hydrogen and other carbon atoms in the synthesis of C₂H₂. One 2s₂ pair is consequently transferred to the vacant 2pz orbital. Each carbon has two sp hybrid orbitals after the 2s orbital in each atom combines with one of the 2p orbitals.
  • As a result of the atoms' symmetrical alignment in a single plane, C₂H₂ possesses a linear molecular structure. Due to their lower electronegative nature than Hydrogen atoms, all Carbon atoms are situated near the center of the Lewis structure of C₂H₂.

                                              H-C≡C-H

Therefore, it is concluded from the above discussion that the hybridization type of acetylene is 'sp'.

How many moles are in 60.0 grams of water?
Mashutka [201]
<h3>Answer:</h3>

3.33 mol H₂O

<h3>General Formulas and Concepts:</h3>

<u>Math</u>

<u>Pre-Algebra</u>

Order of Operations: BPEMDAS

  1. Brackets
  2. Parenthesis
  3. Exponents
  4. Multiplication
  5. Division
  6. Addition
  7. Subtraction
  • Left to Right

<u>Chemistry</u>

<u>Atomic Structure</u>

  • Reading a Periodic Table
  • Using Dimensional Analysis
<h3>Explanation:</h3>

<u>Step 1: Define</u>

60.0 g H₂O (Water)

<u>Step 2: Identify Conversions</u>

Molar Mass of H - 1.01 g/mol

Molar Mass of O - 16.00 g/mol

Molar Mass of H₂O - 2(1.01) + 16.00 = 18.02 g/mol

<u>Step 3: Convert</u>

  1. Set up:                               \displaystyle 60.0 \ g \ H_2O(\frac{1 \ mol \ H_2O}{18.02 \ g \ H_2O})
  2. Multiply:                             \displaystyle 3.32963 \ mol \ H_2O

<u>Step 4: Convert</u>

<em>Follow sig fig rules and round. We are given 3 sig figs.</em>

3.32963 mol H₂O ≈ 3.33 mol H₂O

How do you find percentage yeild​
ch4aika [34]

Answer:

To calculate the percentage of a specific number, you first convert the percentage number to a decimal. This process is the reverse of what you did earlier. You divide your percentage by 100. So, 40% would be 40 divided by 100.

What is the population of the study​
mixas84 [53]

Answer:

The study population is the subset of the target population available for study (e.g. schizophrenics in the researcher's town). The study sample is the sample chosen from the study population.

Explanation:

In research terminology the Population can be explain as a comprehensive group of individuals, institutions, objects and so forth with have a common characteristics that are the interest of a researcher. Any value which is identified or measured from the characteristics of entire population can be called as Parameter.
