Answer: Negative
Explanation:
This is called an anion. Whenever an atom gains a electron, it becomes negative. When an atom loses an electron, it becomes postitive. Positive atoms are called cation.
After an ionic bond is formed, the charge of the atom that gained an electron will be negative.
What is an ionic bond?An ionic bond, also widely recognized as an electrovalent bond, is a category of interconnection established by the electrostatic attraction of ions with opposing charge in a chemical substance.
When the valence (outermost) electrons of one atom are permanently transferred to another atom, a bond is formed.
An ionic bond is formed between a metal and a nonmetal, whereas a covalent bond is formed between two nonmetals.
An ionic bond is formed by the complete transfer of electrons from one atom to another. When an atom loses one or more electrons, it becomes a cation, or positively charged ion.
When an atom gains one or more electrons, it becomes an anion, a negatively charged ion.
Thus, the atom is negatively charged as it gained electron.

whats the difference between acid , bases and buffers?
Please select me as brainiest. It would make my day.
Answer:
A basic solution will have a pH above 7.0, while an acidic solution will have a pH below 7.0. Buffers are solutions that contain a weak acid and its a conjugate base; as such, they can absorb excess H+ions or OH– ions, thereby maintaining an overall steady pH in the solution.
How is burning a piece of wood a chemical change, while boiling water is not? I don’t get it....well i do but i need a answer.:/
Answer:
A burning piece of wood is a chemical change, because you alter it, and it turns to ashes, and it is irreversible, where as you can make water cold again
Answer:
youre creating a new substance in a chemical reaction
Explanation:
by boiling water, you arent making anything new. you're just changing the form of the water.
by burning wood, you're inducing a chemical reaction because some new substance is being made with the reactants

Suppose a scientist developed a hypothesis stating that a certain substance slowed down the growth of chili pepper plants. Briefly describe a controlled experiment
the scientist could conduct to test the hypothesis. Identify the controlled variables, the independent variable(s), and the dependent variable(s).
Answer:
The experiment consists of three different treatments:
1- Fifty (50) chili pepper plants treated with the substance X suspected to slow down the growth
2- Fifty (50) no treated chili pepper plants that grown in normal conditions
3- Fifty (50) chili pepper plants treated with a substance known to slow down the growth (positive control)
Dependent variable: plant growth
Independent variable: the amount of substance x (suspected to slow down plant growth)
Explanation:
The dependent variable is the variable that is being measured, while the independent variable isn't changed by the other variables in the experiment. In this case, the question is how chili pepper plants grow in response to the substance x, which is suspected to slow down the plant growth. During the experimentation, the plant growth will represent the dependent variable being analyzed. On the other hand, chili pepper growth will be in response to changes in the amount of substance x the plants receive, therefore being the independent variable.
Hypothesis development for substance.
A hypothesis is a temporary or tentative arrangement or explanation that is made for the experiment on the basis of an assumption. The experiments highlight the development of certain substances that slowed down to the growth of the chili pepper plans.
Thus the answer is slow growth, normal growth, and positive fast growth.
The assumed experiment consists of 3 treatments. As the first (50) chili pepper plants treated with substance X tend to slow down the growth. The second plant shows a grown in normal conditions. The 3rd plant sows the slow down the growth (positive control).Thus the dependent variable is then planted growth and the independent variable is substance X.Learn more about the scientist's development.

Both lipids and carbohydrates can be used by the cell as -
A. O replacements for salts.
В.
catalysts for metabolic reactions.
c. building blocks for RNA.
D
sources of energy.
D both can be used as sources of energy
The similarity between lipids and carbohydrates is that both are classes of chemical compounds that are found in living things. Thus, option D is correct.
What are the use of lipid and carbohydrate?Two of the four significant biomolecules include lipids and carbohydrates. They are both sources of energy.
However, although lipids store energy for later use and release it more slowly, carbs are available as instant energy sources. Thus, this is the primary distinction between lipids and carbs.
More energy is stored in lipids than in an equivalent mass of carbs. To release their energy, however, carbohydrates are easier to digest than lipids.
This indicates that they are made up of many carbon atoms with bonds to oxygen and hydrogen.
Therefore, Both lipids and carbohydrates can be used by the cell as sources of energy.

what happens to a enzyme after it has completed a reaction?
Answer: The enzyme will always return to its original state at the completion of the reaction. One of the important properties of enzymes is that they remain ultimately unchanged by the reactions they catalyze. After an enzyme is done catalyzing a reaction, it releases its products (substrates).
Enzymes are not consumed in the reaction, they can continue catalyzing more reactions, they can remain bound to the product or they can be degraded.
What are enzymes?Enzymes are biomolecules that catalyze chemical reactions in living organisms. They are typically proteins, although RNA molecules known as ribozymes also exist. Enzymes are responsible for many of the metabolic processes that occur in cells and are essential for life. They are highly specific, meaning that they typically only catalyze one or a few specific reactions, and they increase the rate of reactions by reducing the activation energy required for the reaction to occur.
After an enzyme has completed a reaction, it is still present and can continue to catalyze more reactions. Enzymes can catalyze thousands of reactions per second, and they can remain active for long periods of time. However, enzymes can also be inactivated or destroyed by various factors, such as high temperatures, changes in pH, or the presence of certain chemicals

I. Plant cells are formed from fertile soil. II. Animal cells must function properly for an organism to be healthy. III.Cells make up the petals, stem, and leaves of a lily plant. IV. Bacteria are produced from other living bacteria. Which describes the statements that Schwann and Schleiden would make? Schwann would make Statement I and Schleiden would make Statement IV. Schwann would make Statement II and Schleiden would make Statement III. Schwann would make Statement III and Schleiden would make Statement II. Schwann would make Statement IV and Schleiden would make Statement I.
Answer:
Schwann would make statement II and Schleiden would make statement III
Explanation:
Schleiden, a German botanist and Schwann was a zoologist, both have found that the plants and animals are made up of cells, they both shared their research and observation with each other and made the conclusion that all living organisms are made up of cells.
As mentioned above Schleiden was a botanist so he must have concluded and described that all plant organs are made up of cells, similarly as zoologist he proposed that the cell must function properly in an organism.
Answer:
B- Schwann would make Statement II and Schleiden would make Statement III.

Why is mass a better unit for measuring matter than weight?*
Because mass can change, but weight doesn't
Because mass is constant, while weight depends on gravity.
Because it makes more sense.
Answer:
Because mass is constant, while weight depends on gravity.
Explanation:
