Explanation:

The products : Zn₃(PO₄)₂ (s) + KClO₃ (aq)

Given

reaction: Zn(ClO₃)₂ (aq) + K₃PO₄ (aq)

Required

The products

Solution

Double-Replacement reactions :  an ion exchange between two ion compounds in the reactant to form two new ion compounds in the product

General formula :

AB + CD ⇒ AD + CB

One of the characteristics of the double replacement reaction is the presence of precipitated compounds

Zn(ClO₃)₂ (aq) + K₃PO₄ (aq) ⇒ Zn₃(PO₄)₂ (s) + KClO₃ (aq)

Zn₃(PO₄)₂ (s)⇒ precipitated compounds, so that this reaction can occur

Answer:

21 periodic tables equals alot of stuff

Explanation:

Answer:

d. Copper (II) sulfate

Explanation:

Given data:

Mass of Al = 1.25 g

Mass of CuSO₄ = 3.28 g

What is limiting reactant = ?

Solution:

Chemical equation:

2Al + 3CuSO₄   →   Al₂ (SO₄)₃ + 3Cu

Number of moles of Al:

Number of moles = mass/molar mass

Number of moles = 1.25 g/ 27 g/mol

Number of moles = 0.05 mol

Number of moles of CuSO₄:

Number of moles = mass/molar mass

Number of moles = 3.28 g/ 159.6 g/mol

Number of moles = 0.02 mol

now we will compare the moles of reactant with product.

              Al           :           Al₂ (SO₄)₃

                2          :             1

              0.05       :          1/2×0.05=0.025 mol

               Al           :            Cu

                2            :              3

              0.05         :            3/2×0.05 = 0.075 mol

        CuSO₄           :           Al₂ (SO₄)₃

               3             :             1

              0.02         :          1/3×0.02=0.007 mol

        CuSO₄           :            Cu

              3               :              3

              0.02         :              0.02  

Less number of moles of reactants are produced by CuSO₄ thus it will act as limiting reactant.

-It defined the nucleus for the first time. √

-Electrons exist only in energy levels. ×

-Electrons orbit the nucleus. ×

-Electrons exist in any location in the atom. √

----------------------------------------------------------------------------------------------------------------

Physicist Ernest Rutherford envisioned the atom as a miniature solar system, with electrons orbiting around a massive nucleus, and as mostly empty space, with the nucleus occupying only a very small part of the atom. The Rutherford model was devised by the New Zealand-born physicist Ernest Rutherford to describe an atom. Rutherford directed the Geiger–Marsden experiment in 1909, which suggested, upon Rutherford's 1911 analysis, that J. J. Thomson's plum pudding model of the atom was incorrect.

Answer:

solid iodine chlorine gas

The correct order for ranking solid iodine, liquid bromine, and chlorine gas in order of increasing intermolecular force strength is;  chlorine gas < liquid bromine < solid iodine.

Intermolecular forces are forces that hold substances together in a particular state of matter. Intermolecular forces increase in the order; gases < liquids < solids. Solids have the highest magnitude of intermolecular interaction between particles.

Bearing this in mind, the correct order for ranking solid iodine, liquid bromine, and chlorine gas in order of increasing intermolecular force strength is;  chlorine gas < liquid bromine < solid iodine.

Explanation:

Answer:

Of the following substances, PCl₃ has the highest boiling point

Explanation:

The given substances and their boiling point from online resources are;

Krypton, Kr, boiling point = -153.4°C

Chlorine gas, Cl₂, boiling point = -34.6°C

Borane, BH₃, (transient compound), boiling point of the dimer it forms B₂H₆ = -164.85°C

Methane, CH₄, boiling point = -161.6°C

Phosphorus trichloride, PCl₃, boiling point = 76.1°C

Therefore, given that PCl₃ is a volatile liquid at room temperature, while the other substances are gases and that PCl₃ has the highest boiling point of all the substances of 76.1°C, the substance with the highest boiling point is PCl₃.

Answer:

oxygen is an example of a diatomic molecule found in earth's atmosphere!

Explanation:

Answer:

a particle with no charge is a neutron.

Answer:

true

Explanation: all matter down to the molecular or even atomic level has a constant vibration and movement. The only time that any matter could stop moving would be at absolute zero.

RTP stands for Room Temperature and Pressure.

One mole of any gas has a volume of 24 dm 3 or 24,000 cm 3 at rtp (room temperature and pressure). This volume is called the molar volume of a gas. This equation shows how the volume of gas in dm 3 at rtp is related to the number of moles: volume of gas at rtp = number of moles × 24.

Answer:

C 2

Explanation:

2Nal + Cl2 → 2NaCl + I2

This is balanced equation

Answer:

The pressure correction in the ideal gas equation accounts for the intermolecular attractive forces between gas molecules. Vanderwaal constant 'a' measures the magnitude of intermolecular attractive forces between the particles.  

Thevolume correction to the total volume per mole occupied by gas molecules, it closely corresponds to the volume per mole of the liquid state, whose molecules are closely layered. Vanderwaal constant 'b' measures the volume excluded by a mole of particles.

Vander waals equation followed by real gas is:

[tex](P+\frac{an^2}{V^2})(V-nb)=nRT[/tex]

where,

P = pressure of gas

V = volume of gas

n = number of moles of gas

R = gas constant

Explanation:

What is being described in the question above, that is a soft weak like layer the upper part of the mantle where lithospheric plates is known as the asthenosphere. In the study of earth's mantle, the asthenosphere is one of the region that can be overlooked as it constitutes part of the upper mantle with its counterpart; lithosphere.

Some of the properties of asthenosphere is the fact it has high temperature, it is viscous and it is ductile. It is also characterized by its density.

El mismo nivel, pero diferente subnivel y orbital

Explanation:

En un átomo, el número cuántico principal n muestra el nivel de energía del electrón.

Si dos electrones tienen el mismo valor del número cuántico principal n, simplemente significa que están en el mismo nivel de energía.

Sin embargo, cuando los números cuánticos l y ml difieren, los electrones deben estar en diferentes subniveles y orbitales.

From left box to right box: Footwall, fault plane, hanging wall

Explanation:

A foot wall is the one holding us the hanging wall so the highest piece. Think of rock climbing. You put your feet on the wall or rocks to push yourself up. The foot wall is the rocks for the hanging wall.

The hanging wall is the part that's "hanging" from the other wall. So the lowest one. Think of it as the part that's hanging.

A fault plane is where the place where the fault happens which would be where there is the difference in elevations originate from. Think of it like the crack in the middle.

Answer: The ionic formula of compound is [tex]CoP[/tex] and the name is cobalt phosphide.

Explanation:

For formation of a neutral ionic compound, the charges on cation and anion must be balanced. The cation is formed by loss of electrons by metals and anions are formed by gain of electrons by non metals.

Here element Co is having an oxidation state of +3 called as [tex]Co^{3+}[/tex] cation and phosphprous forms [tex]P^{3-}[/tex] anion with oxidation state of -3. Thus they combine and their oxidation states are exchanged and written in simplest whole number ratios to give neutral [tex]CoP[/tex]

The nomenclature of ionic compounds is given by:

1. Positive is written first followed by the oxidation state of metal in roman numerals in square brackets.

2. The negative ion is written next and a suffix is added at the end of the negative ion. The suffix written is '-ide'.

Thus the name of [tex]CoP[/tex] is cobalt phosphide.
