Why do you think there are many wind systems between a pole and the equator instead of just one large single wind system

1 answer:

4 0

As a result, the Poles have high pressure (cold air) while the Equator has low pressure (warm air). Hot air from the Equator rises and goes toward the Poles, while colder air from the Poles lowers and moves toward the Equator, resulting in a continuous wind pattern.

What is the balanced equation and type of reaction for: <br> Copper metal+aqueous silver nitrate

Gnesinka [82]

Answer:

Cu(s) + 2AgNO3(aq)→Cu(NO3)2(aq)+2Ag(s)

This chemical equation means:

One mole of solid copper plus two moles of aqueous silver nitrate produce one mole of copper(II) nitrate plus two moles of solid silver.

This is a single replacement reaction in which the metal copper replaces the metal silver.

If 0.2 g of nitrobenzene are added to 10.9 g of naphthalene, calculate the molality of the solution. (given: molar mass of nitro

In-s [12.5K]

Molality is defined as 1 mole of a solute in 1 kg of solvent.

Molality=

$\frac{Number of moles of solute}{Mass of solvent in kg}$

Number of moles of solute, n=

$\frac{Given mass of the substance}{Molar mass of the substance}$

Given mass of the nitrobenzene=0.2 g

Molar mass of the substance= 123.06 g mol⁻¹

Number of moles of nitrobenzene,

$n= \frac{0.2 }{123.06}$

Number of moles of nitrobenzene, n= 0.0016 mol

Mass of 10.9 g of naphthalene in kg=0.0109

$Molality= \frac{0.0016}{0.0109 }$

Molality= 0.146 m

A nonmetal

mars1129 [50]

$^{16}_{\phantom{1}8}\text{O}$ .

Oxygen-16 is the atom in question.

Atomic number: 8.
Mass number: 16.

<h3>Explanation</h3>

The superscript of the ion says "2-". That means that the ion here carries a charge of -2.

The charge is negative, meaning that there are more electrons (which are negative) than protons (which are positive) in that ion.
The size of the charge is 2. There are two more electrons than protons in that ion.

There are 10 electrons in total in that ion. There are two more electrons than protons. That means that there are 10 - 2 = 8 protons in that ion.

The atomic number of an atom is the same as its number of protons. The atomic number of X is 8.

The atomic number determines the element. Atomic number 8 is oxygen. Thus element X is oxygen.

Mass number is the sum of number of protons and neutrons in an atom. 8 + 8 = 16 for this atom.
