What makes the desert unique from other biomes.

Chemistry
1 answer:
Vlada [557]3 years ago
5 0

Explanation:

Desert biomes are the driest of all the biomes. In fact, the most important characteristic of a desert is that it receives very little rainfall. Most deserts receive less than 300 mm a year compared to rainforests, which receive over 2,000 mm.

A gaseous mixture contains 5.0 moles of nitrogen and 10.0 moles of helium . What is the total pressure if the temperature is 25
jolli1 [7]

Answer:

A) 122 atm

Explanation:

PV = nRT

Solve for P --> P = nRT/V

n = 10.0 mol + 5.0 mol = 15.0 mol

R = 0.08206 L atm / mol K

T = 25 + 273 = 298 K

V = 3.0

P = (15.0)(0.08206)(298) / (3.0) = 122 atm

The molecule CO2 is arranged in a linear molecular geometry. TRUE FALSE
antiseptic1488 [7]

I would say true because the Valence Shell Electron Pairs will Repel each other. When they do they are forced to the opposite side of the Carbon atom giving CO2 a linear molecular shape. The CO2 bond angle will be 180 degrees since it has a linear molecular geometry.

3.Write the symbol of the element that has a charge of +1 when it has 71 electrons.​
tigry1 [53]

The symbol : \tt _{72}^{178}Hf^{+1}

<h3>Further explanation </h3>

There are two components that accompany an element, the mass number and atomic number

Atoms are composed of 3 types of basic particles (subatomic particles): <em>protons, electrons, and neutrons </em>

The Atomic Number (Z) indicates the number of protons and electrons in an atom of an element.

Atomic number = number of protons = number of electrons ⇒ neutral number

Atomic mass is the sum of protons and neutrons

Atomic Number (Z) = Atomic mass (A) - Number of Neutrons

The element has 71 electrons and a charge of +1 , so

Number of protons = 71 + 1 = 72

Number of protons = the atomic number = 72

The element with atomic number 72 is Hafnium(Hf)

The atomic mass of Hf = 178 g/mol
