Answer:

This question is incomplete

Explanation:

This question is incomplete. However, to determine the number of different element participating in a reaction, count the number of individual atoms participating the reaction. For example,

H₂SO₄ + 2NaOH  ⇒  Na₂SO₄ + 2H₂O

The number of different elements involved in the reaction above are hydrogen (H), sulphur (S), oxygen (O) and sodium (Na). This means there are 4 different elements involved in the reaction.

But to determine the total number of atoms involved in a reaction, one must first ensured the reaction is balanced (because the number of each atom must be considered). Using the same reaction illustrated earlier hydrogen (H) has 2 atoms in H₂SO₄ and 2 atoms in NaOH, sulphur (S) has 1 atom in H₂SO₄, oxygen (O) has 4 atoms in H₂SO₄ and 2 atoms in NaOH and sodium (Na) has 2 atoms in NaOH. Thus, total number of atoms is 13 atoms.

Note that the number of atoms on the reactant side would be same as number of atoms on product side because of law of conservation of matter. Thus, participating atoms in the reaction is 13

AnnZ [28]
For starters, I would get the same height for each paper, such as a counter top. Then, I would make said paper. You would use a timer of course, maybe even something like a speed gun to calculate the speed as said paper falls. You would push each paper off the counter top and calculate the speed for each paper. This is the easiest way to prove your hypothesis.

erastova [34]

Answer:

B. Atom, molecule, cell, organism

Explanation:

Atoms make up molecules. Molecules make up cells. Cells make up tissue. A number of tissues working together creates an organ. Multiple organs working together creates an organ system. Organ systems working together creates one happy, functioning organism. :)

TRUE OR FALSE :Normal cells will not divide unless the nutrients they require are already presen True False
Diano4ka-milaya [45]

Answer:

False

Explanation:

Cell division is a primary procedure by all cells. This process in the life cycle of cells ensures that new cells (daughter cells) are produced. The two major process are; meiosis and mitosis.

Normal cells would divide if the nutrients required are not present, since water is the main nutrient required. But in some cases, the division process may lead to an effect on one or both daughter cells. This effect is called mutation, thereby mutated cells may be produced.
