What is the formula for this compound?

1 atom of copper, 1 atom of sulfur, 4 atoms of oxygen

Answers

Answer:

The third one: [tex]CuSO_4[/tex]

Explanation:

Again you are going to want to look at a periodic table so you can determine the symbol of each atom.

The symbol for copper is Cu, the symbol for sulfur is S and the symbol for Oxygen.

There is 1 atom of copper in the compound

So we have Cu

There is 1 atom of sulfur in the compound

So we would have CuS

There are 4 atoms of oxygen in the compound

So we would have [tex]CuSO_4[/tex]

Note that the little number at the bottom left after each symbol indicates how many atoms of that element are in that compound.

An atom's electron configuration ends with 3p4. If another atom has seven more electrons, what would be the continuation of the electron configuration?

Answers

The continuation of the electron configuration would be [tex]3p^6, 4S^2, 3d^3[/tex].

The initial p orbital is partially filled. Hence, it has to be completely filled first in order to obey the orbital filling rule. Lower energy orbitals are first filled before higher energy orbitals.

After filling the p orbital with 2 electrons from the remaining 7 electrons, higher energy orbital 4s and 3d can then be filled.

The reaction below is at dynamic equilibrium. Upper N subscript 2 (g) plus 3 upper H subscript 2 (g) double-headed arrow 2 upper N upper H subscript 3 (g). Which statement is true for the equilibrium system? The concentration of NH3 is greater than the concentration of N2. The concentration of NH3 equals the concentration of N2. The rate of the forward reaction equals the rate of the reverse reaction. The rate of the forward reaction is greater than the rate of the reverse reaction.

Answers

For the reaction below at dynamic equilibrium, it is true that the rate of the forward reaction equals the rate of the reverse reaction.

Let's consider the following reaction at equilibrium.

N₂(g) + 3 H₂(g) = 2 NH₃(g)

What is the chemical equilibrium?

Is a state in which the concentrations of reactants and products are constant and the forward reaction rate and constant reaction rate are equal.

What is the equilibrium constant?

The equilibrium constant (K) is the ratio of the concentrations of the products to the concentrations of the reactants, all raised to their stoichiometric coefficients.

Let's consider which statement is true for the equilibrium system.

The concentration of NH₃ is greater than the concentration of N₂. FALSE. There is not enough information to confirm this, we would need to know the value of K.The concentration of NH₃ equals the concentration of N₂. FALSE. There is not enough information to confirm this, we would need to know the value of K.The rate of the forward reaction equals the rate of the reverse reaction. TRUE. This is always true for a reaction at equilibrium.The rate of the forward reaction is greater than the rate of the reverse reaction. FALSE. At equilibrium, both rates are equal.

For the reaction below at dynamic equilibrium, it is true that the rate of the forward reaction equals the rate of the reverse reaction.

Consider the following system at equilibrium. CaCO3(s) Double headed arrow. Ca2 (aq) CO32â€""(aq) The addition of which compound will cause a shift in equilibrium because of a common ion effect? CCl4 CO2 CuSO4 Na2CO3.

Answers

The compound that has been capable to shift the equilibrium with common ion effect has been  [tex]\rm \bold{Na_2CO_3}[/tex].  Thus, option D is correct.

The complete equation for the decomposition of calcium carbonate has been:

[tex]\rm CaCO_3\rightleftharpoons Ca^2^+\;+\;CO_3^2^-[/tex]

The equilibrium has been the state in the reaction, when the number of products and has been equivalent to the number of reactants. The increase or decrease in the concentration of any of the reactant or product results in the shift in the equilibrium.

For the given reaction, the addition of Calcium or carbonate ions to the solution results in the increase in the product concentration with the common ion effect, and thereby shifts the equilibrium condition.

The ions liberated by the following compounds has been:

[tex]\rm CCl_4\;=\text{not dissolved}\\CO_2\;+\;H_2O\leftrightharpoons CO_3^-\;+\;H^+\\CuSO_4\leftrightharpoons Cu^2^+\;+\;SO_4^2^-\\Na_2CO_3\leftrightharpoons 2\;Na^+\;+\;CO_3^-[/tex]

The compound, that has been capable of liberating the carbonate ions in the medium has been [tex]\rm \bold{Na_2CO_3}[/tex]. Thus, it results in the shift of the equilibrium due to common ion effect. Hence, option D is correct.

Explanation:

When [tex]^1^8F[/tex] undergoes positron emission, the product nucleus is, [tex]^1^8O[/tex].

What is a positron emission?

In positron emission, also called positive beta decay (β+ decay), a proton in the parent nucleus decays into a neutron that remains in the daughter nucleus, and the nucleus emits a neutrino and a positron, which is a positive particle like an ordinary electron in mass but of opposite charge.

When a proton is converted into a neutron then the positron emission takes place as follows.

[tex]^1_1p\;\rightarrow\;^1_0n\;+\;^0_+1e[/tex]

A positron is represented by the symbol. Therefore, when a positron emission occurs then the resultant nuclei atomic number decreases by a unit mass.

The general equation representing positron emission is as follows.

[tex]^M_ZA\;\rightarrow\;^M_Z_-_1 B\;+\;^0_+1e[/tex]

Hence, fluorine-18 decays by positron emission as follows.

[tex]^1^8_9F\;\rightarrow\;^1^8_8n\;+\;^0_+1e[/tex]

Therefore, when [tex]^1^8F[/tex] undergoes positron emission, the product nucleus is, [tex]^1^8O[/tex].

how much heat is released when 32g of water cools from 46°C and freezes

Answers

The amount of heat released when 32g of water cools from 46°C and freezes is 6182.4 J

Heat: This is a form of energy that brings about the sensation of warmth. The S.I unit of heat is Joules (J)

⇒ Formula:

Q = cm(t₂-t₁).................. Equation 1

⇒ Where:

Q = amount of heat releasedc = specific heat capacity of waterm = mass of watert₁ = Initial temperaturet₂ = Final temperature

From the question,

⇒ Given:

m = 32 g = 0.032 kgt₁ = 46 °Ct₂ = 0 °C (Freezing point)c = constant = 4200 J/kg.°C

⇒ Substitute these values into equation 1

Q = 0.032(4200)(0-46)Q = -6182.4 J

Note: The negative sign tells that heat is released and as such can be ignored.

Hence, The amount of heat released is 6182.4 J

Answer:

I believe A is the correct answer.

Explanation:

I note that another response includes C. as another correct answer.  It is possible, but it depends on what is meant by "fixed shape."  I interpret "fixed shape" as the collection of the gases forming a fixed shape on their own.  Gases fill the container they are in (be it a flask, room, or a planet, so they have a fixed shape by that definition.  But a primary definition of gases is that that take on the shape of their container, not a shape of their own.

A. is correct because perfect gases have no interactions (AKA the Ideal Gas Laws).  They may have interactions, and often do, but they are weak.  That's why the ideal gas laws are a good first approximation to how gases change volume based on temperature and pressure.
