Answer:

Mountains can have a significant effect on rainfall. When air reaches the mountains, it is forced to rise over this barrier. As the air moves up the windward side of a mountain, it cools, and the volume decreases. As a result, humidity increases and orographic clouds and precipitation can develop

Answer:

Por cada 9 moles de zinc, 9 moles de fosfato de zinc se producen.

Explanation:

La reacción balanceada es:

3 Zn+ 2 H₂PO₄ → Zn₃(PO₄)₂ + 2 H₂

Por estequiometria de la reacción (es decir, la relación entre la cantidad de reactivos y productos en una reacción química), las siguientes cantidades de moles de cada compuesto participan de la reacción:

Entonces podes aplicar la siguiente regla de tres: si por estequiometria 3 moles de zinc produce 1 mol de fosfato de zinc, 9 moles de zinc cuántos moles de fosfato de zinc producirá?

[tex]moles de fosfato de zinc=\frac{9 moles de zinc*1 mole de fosfato de zinc}{3 moles de zinc}[/tex]

moles de fosfato de zinc= 9

Por cada 9 moles de zinc, 9 moles de fosfato de zinc se producen.

Answer:

alloy's properties are usually different from those of its component elements. Alloy constituents are usually measured by mass. Unlike pure metals, most alloys do not have a single melting point; rather, they have a melting range in which the substance is a mixture of solid and liquid.

Alloy steels have a wide range of special properties, such as hardness, toughness, corrosion resistance, magnetizability, and ductility. Nonferrous alloys, mainly copper–nickel, bronze, and aluminum alloys, are much used in coinage.

Pure metals are useful but their applications are often limited to each individual metal's properties. Alloys allow metal mixtures that have increased resistance to oxidation, increased strength, conductivity, and melting point; Essentially any property can be manipulated by adjusting alloy concentrations.

Dividing the mass of the water lost by the original mass of hydrate used is equal to the fraction of water in the compound. Multiplying this fraction by 100 gives the percent water in the hydrate.

Explanation:

The amount of water throughout the compound has been determined by dividing the mass of water wasted mostly by original quantity of hydrate used. The above fraction can be multiplied by 100 to get the hydrate's water content in percentages.

The proportion of matter that makes up an object is quantified by its mass. The kilogram, or kg, would be the fundamental SI unit of mass.

Any substance that contains water through the form of H2O molecules is referred to as a hydrate. This water content by weight can vary, but it is typically fixed. The most well-known hydrates seem to be crystalline solids which decompose once the attached water is removed.

Therefore , The amount of water throughout the compound has been determined by dividing the mass of water wasted mostly by original quantity of hydrate used. The above fraction can be multiplied by 100 to get the hydrate's water content in percentages.

The molecular formula for Nickel (IV) Chloride will be NiCl₂. Nickel reacts with chloride to form a salt. The salt is yellow in color and anhydrous.

A molecular formula is a way of presentation of chemical formula of a compound. It gives the information related to the type of atoms, number of atoms which constitutes the compound and the chemical properties.

Molecular formula of a chemical compound can be derived by the valency of element. In this question, molecular formula of the compound can be derived by:

Valency of Nickel = 2

Valency of Chlorine = 1

By the cross-multiplication of valency:

element 1(valency of element 2). element 2 (valency of element 1)

= Ni (1). Cl(2)

= NiCl₂

Therefore, the molecular formula of Nickel (IV) chloride will be NiCl₂.

Explanation:

Answer:

The volume of solution in liters required to make a 0.250 M solution from 3.52 moles of solute is 14.08 liters of solution

Explanation:

The question relates to the definition of the concentration of a solution which is the number of moles per liter (1 liter = 1 dm³) of solution

Therefore we have;

The concentration of the intended solution = 0.250 M

Therefore, the number of moles per liter of the required resolution = 0.250 moles

Therefore, the concentration of the required solution = 0.250 moles/liter

The volume in liters of the required solution that will have 3.52 moles of the solute is given as follows;

The required volume of solution = The number of moles of the solute/(The concentration of the solution)

∴ The required volume of solution = 3.52 moles/(0.250 moles/liter) = 14.08 liters

The required volume of solution to make a 0.250 M solution from 3.52 moles of solute = 14.08 liters.

Therefore the number of liters required to make a 0.250 M solution from 3.52 moles of solute = 14.08 liters.

Explanation:

The balanced equation for the reaction between NaOH and H2SO4 is given as;

2NaOH + H2SO4 → Na2SO4 + 2H2O  

2 mol of NaOH reacts with 1 mol of H2SO4

5g of NaOH was dissolved in 1000cm3.

Mass = 5 g

Molar mass = 40 g/mol

Volume = 1000 cm3 = 1 L

Number of moles = Mass / Molar mass

Number of moles = 5 / 40 = 0.125 mol

Molarity = Number of moles / Volume

Molarity = 0.125 / 1 = 0.125 M

25cm3 of this solution neutralized 28.3cm3 of solution containing 7.2gdm-3 of impure H2SO4.

CaVa / CbVb = Na / Nb ; where a = acid and b = base

Va = 28.3cm3

Vb = 25cm3

Ca = ?

Cb = 0.125 M

Na = 1

Nb = 2

I. The molarity of H2SO4

Solving for Ca;

Ca = CbVb * Na / (Va * Nb)

Cb = (0.125 * 25 * 1 ) / ( 28.3 * 2)

Cb = 0.0552 M

II. The concentration of the pure acid on gdm-3

Molarity = Mass conc / Molar mass

Mass Conc = Molarity * Molar mass

Mass Conc = 0.0552 * 98.079

Mass Conc = 5.41 g/dm3

III. % impurity of the acid

Percentage Impurity = Mass of pure / Mass of Impure   *  100

Percentage Impurity = 5..41 / 7.2 * 100

Percentage Impurity = 75.14%

Crystallography. an arrangement in space of isolated points (lattice points ) in a regular pattern, showing the positions of atoms, molecules, or ions in the structure of a crystal.

If an atom experiences sufficient thermal activation, it can move to a neighboring lattice position.4 If the vibration frequency of the atom is v and the atom has Z nearest neighbors, the total number of jump attempts is vZ. However, only a small fraction of the attempts will be successful, with a probability depending on the ratio between the necessary activation energy for a single jump QD and the thermal activation kBT. The effective jump frequency ΓD is then

(5.6)

With each successful jump, the atom travels one atomic distance λ and the total traveling distance in unit time is thus ΓDλ. Substituting the jump frequency ΓD into the expression for the root mean square displacement of a random walker [equation (5.5)] and using the spatial coordinate r leads to

Answer:

10.0 g of AgI will produce 5.28 g of Ag₂S

Explanation:

The balanced equation of the reaction is given below:

2AgI + Na₂S ----> Ag₂S + 2NaI

From the equation of reaction, 2 moles of AgI produces 1 mole of Ag₂S

The moles of a substance is related to its mass by a quantity known as molar mass which is defined as the mass of one mole of that substance.

Molar mass of AgI = (108 + 127) g = 235 g

Molar mass of Ag₂S = (108 × 2 + 32) g= 248 g

Mass of 2 moles of AgI = 2 × 235 g = 470 g

470 g of AgI produces 248 g of Ag₂S

10 g of AgI will produce 248 /470 × 10 g of Ag₂S = 5.28 g

Therefore, mass of Ag₂S produced = 5.28 g

Answer:

Explanation:

0.25 M

The molarity of a solution will be 4.27M .

Molarity (M), often known as molar concentration, is the concentration of a solution expressed in moles of solute per liter of solution.

Solution can be considered as a mixture of more than one component. It may be homogeneous solution as well as heterogeneous solution.

Gram to mole conversion:

[tex]=\;2.75\;g.\;\frac{1\;mol}{58.44g} \\=\;0.0470 \;mol[/tex]

Molarity of the solution can be calculated by using the following formula:

It is calculated that, moles of solute = 0.0470 mol, volume of the solution = 1100 mL.

Now, put the value of given data in molarity formula:

[tex]Molarity=\frac{Moles\;of\;the\;solute}{Volume \;of\; the\; solution} \\=\frac{0.0470\;mol}{1100 \;mL} \\=\;4.27\;mol/mL\\=\;4.27\; M[/tex]

Therefore,  the molarity of a solution will be 4.27M.
