Alexeev081 [22]

Answer:

A crystalline solid

Explanation:

Most solids form with a regular arrangement of their particles because the overall attractive interactions between particles are maximized, and the total intermolecular energy is minimized, when the particles pack in the most efficient manner. The regular arrangement at an atomic level is often reflected at a macroscopic level.  Liquids dont use to have this kind of arrangements or shapes.

My name is Ann [436]

Answer:

A.) Absorb and store

Explanation:

The reaction for photosynthesis is:

6CO_{2}+ 12H_{2}  O → C_{6} H_{12} O_{6}  +6H_{2} O  (reaction conditions: light and chlorophyll)

<em>carbon dioxide + water → glucose + water</em>

<em />

This means light energy is <u>absorbed</u> and <u>stored</u> as sugar molecules and energy for the plant

Therefore, the photosynthesis reaction will <u>  absorb  </u> energy and <u>  store  </u> it in the chemical bonds.

Draw the skeletal structure for the linear form of d-glyceraldehyde
Mandarinka [93]
The structural form of D-glyceraldehyde is shown in the picture. As you can see, the L-glyceraldehyde and the D-glyceraldehyde are isomers. The D-isomer has the OH placed at the right side of the structure. Thus, the right side, encased in a red box, is the structure for D-glyceraldehyde.

timama [110]

Answer: increased

Explanation:

Powdered zinc has a greater surface area than zinc granules. If the same mass of zinc and volume of acid is used, it will be observed that the powdered zinc will react faster since it provides a greater surface area for reaction compared to zinc granules. The greater the available surface area of reactants, the greater the rate of reaction. Higher surface area means that more particles are available for reaction.
