The elements used for artistic objects are components like color, form, line, shape, space, texture, and value.

Explanation:

They forms the basic building blocks of art. A two-dimensional painting or three-dimensional sculpture are decided by the artist. Line, shape, form may encloses volume a such as cube, cylinder, sphere, pyramid.

Value defines the shades of the colors. Spaces are defined the depthness. Colour made up hue having the name of colour value being the darkness or brightness of the colour. Intensity describes the quality of purity and brightness .Texture describes how things appear or feel touched.

Identify which one is the reducing agent in this reaction

Romashka-Z-Leto [24]

Answer:

Na.

Explanation:

The oxidation-reduction reaction contains a reductant and an oxidant (oxidizing agent).

An oxidizing agent, or oxidant, gains electrons and is reduced in a chemical reaction. Also known as the electron acceptor, the oxidizing agent is normally in one of its higher possible oxidation states because it will gain electrons and be reduced.

A reducing agent (also called a reductant or reducer) is an element (such as calcium) or compound that loses (or "donates") an electron to another chemical species in a redox chemical reaction.

For the reaction:

2Na + S → Na₂S.

Na is oxidized to Na⁺ in (Na₂S) (loses 1 electron). "reducing agent".

S is reduced to S²⁻ in (Na₂S) (gains 2 electrons). "oxidizing agent".

Why is a balanced symbol equation better at describing the reaction than a word equation

AleksandrR [38]

Answer:

The advantages described below

Explanation:

Advantages of a balanced chemical equation versus word equation:

easier to read: chemical equations typically only take one line and they include all the relevant information needed. They are short-hand notations for what we describe in words.
balanced chemical equations show molar ratio in which reactants react and the molar ratio of the products. Those are coefficients in front of the species. This is typically not included in a word equation, for example, hydrochloric acid reacts with potassium hydroxide. The latter statement doesn't describe the molar ratio and stoichiometry.
includes relevant information, such as catalysts, temperature and pressure above the arrow in the equation. We wouldn't have this in a word equation most of the time.
shows the stoichiometry of each compound itself, e. g. if we state 'ammonia', we don't know what atoms it consists of as opposed to $NH_3]$ .
includes states of matter: aqueous, liquid, gas, solid. This would often be included in a word equation, however.

As a general rule, how many specific substrates can bind to an enzyme?

san4es73 [151]

Answer:

Enzyme Active Site and Substrate Specificity

There may be one or more substrates for each type of enzyme, depending on the particular chemical reaction. In some reactions, a single-reactant substrate is broken down into multiple products. In others, two substrates may come together to create one larger molecule.
