Answer:
C.)organs are a group of two or more different types of tissues that work together to perform a specific function
Explanation:
Cells of similar function are grouped together into tissues. For example, cardiac muscle tissue is present only in the heart, and made up of specialised cells called cardiomyocytes, or cardiac muscle cells. These cells contract to pump blood around the body.
The heart is an organ, consisting of multiple types of tissue including cardiac muscle tissue, connective tissue, blood vessels and epithelial tissue. Therefore, organs represent a group of at least two types of tissue that work together to carry out functions in the body.
Answer:
Sediment to sedimentary rock (and vice versa) is Compactation and Cementation.
Explanation:
This happens via Lithification, which is the compacting of sediments under pressure.

Explanation:</h3>
<u>Step 1: Define</u>
[RxN] 2AlF₃ + 3K₂O → 6KF + Al₂O₃
[Given] 15.524 g KF
<u>Step 2: Identify Conversions</u>
[RxN] 6 mol KF = 2 mol AlF₃
Molar Mass of K - 39.10 g/mol
Molar Mass of F - 19.00 g/mol
Molar Mass of Al - 26.98 g/mol
Molar Mass of KF - 39.10 + 19.00 = 58.1 g/mol
Molar Mass of AlF₃ - 26.98 + 3(19.00) = 83.98 g/mol
<u>Step 3: Stoichiometry</u>
- Set up:
- Multiply/Divide:
<u>Step 4: Check</u>
<em>Follow sig fig rules and round. We are given 5 sig figs.</em>
7.47966 g AlF₃ ≈ 7.4797 g AlF₃
The oxidation number of elements becomes increasingly higher from left to right. Elements have more than one stable oxidation state as we move from left to right in the periodic table.
<h3>What does periodic table mean?</h3>
The periodic table, commonly known as the periodic table of elements, is set up so that scientists may rapidly determine an element's mass, number of electrons, electron configuration, and other distinctive chemical characteristics.
<h3>Why is the periodic table important?</h3>
All known elements are grouped together in the periodic table of elements into groups with related properties. It becomes a crucial tool for chemists, nanotechnologists, and other scientists as a result. You can forecast how chemicals will react if you learn to use and comprehend the periodic table.

Answer:
No.
Explanation:
During chemical reaction, atomes cannot be created or destroyed, they can only react together to form <em>E</em><em>l</em><em>e</em><em>m</em><em>e</em><em>n</em><em>t</em><em> </em>or <em>C</em><em>o</em><em>m</em><em>p</em><em>o</em><em>u</em><em>n</em><em>d</em><em> </em>at the <em>P</em><em>r</em><em>o</em><em>d</em><em>u</em><em>c</em><em>t</em><em> </em>side.
