Answer:

The ratio by number of H atoms to O atoms is: 4:5

Explanation:

The mineral torbernite, : Cu(UO_2)_2(PO_4)2⋅8H_2O

Number of oxygen atoms in the mineral :

=2\times 2+4\times 2+8\times 1=20

Number of hydrogen atoms in the mineral :

=8\times 2=16

The ratio by number of H atoms to O atoms is:

\frac{16}{20}=\frac{4}{5}=4:5

H:O = 4:5; (UO₂)₂ = 4 O atoms; (PO₄)₂ = 8 O atoms: 8H₂O = 16 H atoms + 8 O atoms; Total = 16 H atoms + 20 O atoms; H:O = 16:20 = 4:5

Compare the reactivity between lithium and sodium towards oxygen. ​
Scrat [10]
Reactivity of Group 1 and 2 elements increases as you go down the periodic table. So sodium is more reactive than lithium. Sodium will react with oxygen forming Na2O (sodium oxide). Lithium forms lithium oxide (Li2O).

Function of leaf in points​
klasskru [66]

Explanation:

The main function of a leaf is to produce food for the plant by photosynthesis. Chlorophyll, the substance that gives plants their characteristic green colour, absorbs light energy.

  • Photosynthesis.
  • Transpiration.
  • Guttation.
  • Storage.
  • Defense.

I will be describing what each of these do to the plant.

  • <u>Photosynthesis: </u>Photosynthesis is a process used by plants and other organisms to convert light energy into chemical energy that can later be released to fuel the organisms' activities.
  • <u>Transpiration</u>: Transpiration is the process of water movement through a plant and its evaporation from aerial parts, such as leaves, stems and flowers. Water is necessary for plants but only a small amount of water taken up by the roots is used for growth and metabolism. The remaining 97–99.5% is lost by transpiration and guttation.
  • <u>Guttation</u>: Guttation is the exudation of drops of xylem sap on the tips or edges of leaves of some vascular plants, such as grasses, and a number of fungi. Guttation is not to be confused with dew, which condenses from the atmosphere onto the plant surface. Guttation generally happens during the night time.
  • <u>Storage</u>: A storage organ is a part of a plant specifically modified for storage of energy (generally in the form of carbohydrates) or water. Storage organs often grow underground, where they are better protected from attack by herbivores.
  • <u>Defense</u>: The first line of defense in plants is an intact and impenetrable barrier composed of bark and a waxy cuticle. Both protect plants against herbivores. Other adaptations against herbivores include hard shells, thorns (modified branches), and spines (modified leaves).

<u>Hope this helps!</u>

How can I tell how many electrons in each energy level? When my question states "third sublevel" does this mean sublevel P?
nikitadnepr [17]
Sorry for the delay! My internet is a bit bad.
P is the third sublevel. Each sublevel (the angular momentum quantum number), has its own number:
<span>s = 1, p =3, d = 5, f = 7</span>
The number of electrons for each is:
s-2
p-6
d-10
f-14
It's easier to just memorize these numbers, but the equation for determining the sublevel number is 2n (n = the principal quantum number). The principal quantum number is based on the period the element is in.
