GIVING BRAINLIEST!!! A student observes a beaker of room temperature water resting on a table. She states that the beaker of water does not have any energy. Which statement below is accurate regarding her observation?a. She is correct because the beaker of water is not moving.


b. She is incorrect because the beaker of water has thermal energy.


c. She is incorrect because all water contains hydrogen and oxygen.


d. She is correct because the beaker of water is at room temperature.

Answer:

True

Explanation:

Without enough nitrogen there is not enough nutrients for plants to make both aminoacids and many products of secondary metabolism

The answer would be:

Pure substance: specifically a compound

Pure substances can be categorized into compounds and elements. A compound is a pure substance that cannot be broken down physically, but it can be broken down through chemical means. It is this property that differentiates it from mixtures. Mixtures can be broken down by physical and/or chemical means.

Elements on the other hand, cannot be broken down at all because it is in its simplest form and is also considered as a pure substance.

Answer:

Pure substance

Explanation:

Matter can be broadly classified into two categories: Pure substances and Mixtures (homogenous and heterogenous mixtures).

The simplest form of a pure substance is an element which cannot be broken down any further. When two or more elements combine, they form a compound which is also a pure substance. Thus, pure substances are systems that are either composed of a single type of element or a single type of molecule.

For example salt (NaCl) is a compound which is composed of elements: sodium (Na) and chlorine (Cl). These elements (in fact ions, Na+ and Cl-) are held together by a chemical bond. Thus, a pure substance like NaCl can be broken down into its elements through chemical means.

The unknown substance in the given question can therefore be classified as a pure substance

Answer: Red Plate Dinner

Explanation:

If we calculate them with formula for area of circle().

Red Plate - = 36

2 Yellow Plate - 2 * = 2 * 9 = 18

The Red Plate has a bigger area, so the Red plate has more area.

The compound that has both ionic and covalent bonds is .

Further explanation:

The periodic properties are characteristics that are associated with the different elements found in the periodic table. The origin of different properties is the difference in the atomic structure of the different elements.

For a systematic study of the chemical and physical properties of different elements, they are placed in certain columns called groups and horizontal rows called periods. The rows of the table called periods and have metals on the left and non-metals on the right. The columns also called groups contains elements with similar chemical properties.

The ionic bond is a chemical bond between two atoms in which one atom donates its electron to another atom. While covalent bonds involve sharing of electrons between two atoms and reach a more stable electron configuration.

Compounds made from two elements can either have an ionic or covalent bond.

(i) If a compound is made between metal and a non-metal then the bond will be ionic.

(ii)If a compound is made between two non-metals then the bond will be covalent.

(1) In , oxygen(O) and carbon(C) are nonmetals. They form a covalent compound, and bond present in will be covalent bond.

(2) In NaI, sodium (Na) is metal and iodine (I) is a nonmetal. They will form an ionic compound, and bond present NaI will be ionic.

(3) In , carbon(C) hydrogen(H) and oxygen(O) all are nonmetal atoms they will form a covalent compound, and bond present in   will be covalent.

(4) In , sodium(Na) is metal, carbon(C) and oxygen(O) are nonmetals atoms. The bond form between sodium and carbon will be ionic. Also, the bond formed between carbon and oxygen is covalent as both carbon and oxygen are nonmetals. Therefore, has both covalent and ionic bond.

Hence the correct option is 4.

Final answer:

Na2CO3 (sodium carbonate) contains both ionic and covalent bonds.

Explanation:

The compound with both ionic and covalent bonds is Na2CO3 (sodium carbonate).

Na2CO3 contains ionic and covalent bonds because it is formed from the reaction between a metal (sodium) and a polyatomic ion (carbonate). The bonds between the sodium and oxygen atoms in the carbonate ion are ionic, while the bonds within the carbonate ion (between carbon and oxygen) are covalent.

Final answer:

Protons and electrons differ in both their masses and their charges. Protons have a larger mass and positive charge whereas electrons have a smaller mass and negative charge.

Explanation:

The correct answer to your question about proton and electron characteristics is option 4: They have different masses and different charges. To elaborate, a proton is a positive-charged particle found in an atom's nucleus with a relatively high mass. On the other hand, an electron is a negative-charged particle circling the nucleus, with a mass nearly 2000 times lighter than a proton. Thus, they both differ in their masses and in their charges.

Final answer:

The statement that is true about a proton and an electron is that they have different masses and different charges, which corresponds to option (4).

Explanation:

The correct statement about a proton and an electron is that they have different masses and different charges. Therefore, the answer to your question is (4) They have different masses and different charges.

Protons are subatomic particles found in the nucleus of an atom and have a positive electric charge. On the other hand, electrons are subatomic particles that orbit the nucleus of an atom and have a negative electric charge. The mass of a proton is significantly larger than the mass of an electron.

A proton's mass is about 1.6726 x 10-27 kilograms, which is nearly 1836 times the mass of an electron, which is approximately 9.109 x 10-31 kilograms.
