The hypothesis is that
the green coloration of plants is related to sunlight exposure of leaves
The hypothesis is tested by keeping a dark green plant inside a dark closet
The result is that the green coloration faded
The conclusion must be that exposure to sunlight affects the green color of the plants

List 3 ways the periodic table is useful<br> Help!
SashulF [63]

The periodic table arranges the elements into families and periods (vertical and horizontal rows). The elements in each family have similar properties. As you go across a row, the properties vary gradually from one element to the next. The table tells you what elements may have similar chemical and physical properties.The periodic table describes the atomic structure of all known elements. For instance, by looking at the periodic table, you can find out the atomic mass and the number of electrons the element has. Each element has its own separate set of such data. No two elements are the same.This is perhaps the most useful feature of the Periodic Table. It is an excellent reference tool. In one place, you can find many properties of an element.

Ordena de mayor a menor según sus radios iónicos a los siguientes iones:
I am Lyosha [343]

Answer:

The correct order of the elements, taking into account their ionic radius from highest to lowest, is:

<em>a) Cl⁻¹ > F⁻¹ > Na⁺¹ > Mg⁺²</em>

<em>b) S⁻² > O⁻² > Li⁺¹ > Be⁺²</em>

<em>c) S⁻² > Cl⁻¹ > K⁺¹ > Na⁺¹</em>

Explanation:

In ions the ionic radius is determined by the amount of electrons an element gains or loses to become an ion.  The more negative an ion is, the greater its ionic radius.

As a rule, anions (negative charge) have a larger ionic radius than cations (positive charge), because the loss of electrons means a contraction of the ionic radius, while the gain of electrons means a greater radius.

To determine which ionic radius is greater in anions or cations with the same charge, it must be considered that in the periodic table the ionic radius increases from top to bottom and from right to left.

Which of the following reactions below could be properly categorized as a synthesis reaction?
kari74 [83]

Answer:

A synthesis reaction is a type of reaction in which multiple reactants combine to form a single product. Synthesis reactions release energy in the form of heat and light, so they are exothermic. An example of a synthesis reaction is the formation of water from hydrogen and oxygen.
