Which words list the correct order of activated neurons in a reflex arc?

Answers

Answer 1

Answer: Here is the correct order of activated in a reflex arc.
(1) Receptor: where stimulus action is.
(2) Sensory Neuron: responisble of transmitting afferent impulses to the central nervous system.
(3) Integration Center: Sensory impulse to motor impulse; Direct (monosynaptic) or polysynaptic region in CNS.
(4) Motor Neuron: Efferent impulses from integration center to effector.
(5) Effector: Muscle fiber or gland cell that responds to the efferent impulses.

Consider the following reaction: SO2Cl2(g)⇌SO2(g)+Cl2(g) A reaction mixture is made containing an initial [SO2Cl2] of 2.2×10−2M . At equilibrium, [Cl2]= 1.3×10−2M . Calculate the value of the equilibrium constant (Kc).

Answers

The value of equilibrium constant (Kc) will be 0.0188.

Equilibrium constant :

The equilibrium constant of a chemical reaction is the value of its reaction quotient at chemical equilibrium, a state approached by a dynamic chemical system after sufficient time has elapsed at which its composition has no measurable tendency towards further change.

Given reaction:

SO₂Cl₂(g)⇌SO₂(g)+Cl₂(g)

To find:

Kc=?

The equation that represents kc for the given reaction will be:

$k_c=([SO_2][Cl_2])/([SO_2Cl_2])$

On substituting the initial concentration:

$k_c=([SO_2][Cl_2])/([SO_2Cl_2])\n\nk_c=([1.3*10^(-2)][1.3*10^(-2)])/([2.2*10^(-2)-1.3*10^(-2)]) \n\nk_c=0.0188$

Thus, the value of equilibrium constant (Kc)will be 0.0188.

The value of equilibrium constant is equal to the quotient of the products raised to its stoichiometric coefficient over the reaction's reactants raised to its respective stoichiometric coeff. The equation is Kc=[SO2][Cl2]/[SO2Cl2]= [1.3*10^-2][1.3*10^-2]/[2.2*10^-2-1.3*10^-2]=0.0188. The final answer is Kc=0.0188.

Which change occurs when an atom in an excitedstate returns to the ground state?
(1) Energy is emitted.
(2) Energy is absorbed.
(3) The number of electrons decreases.
(4) The number of electrons increases.

Answers

Answer: The correct option is (1).

Explanation:

Whenever an atom in an excited state returns back to its ground state the energy is emitted out in the form of the radiation and the value of energy emitted can be determined by using the expression:

$E=(hc)/(\lambda )$

Where E = Energy of the radiation in joules

h = Planck's constant = $6.63* 10^(-34) J.s$

$\lambda$ = Wavelength of the radiation in meters.

The change that occurs when an atom in an excited state returns to the ground state is that (1) energy is emitted.
It is emitted by photons in the form of light, or in some cases, heat.

It can destroy a community which would make it dense and difficult to survive in and then stimulate a pioneer community starting with moss and ferns. which will start a new little ecosystem. So, these effects would be long term, though it can effect the climate in many different ways.

Which pair are classified as chemical substances? Pick two.elements, mixtures, compounds, solutions.

Answers

Elements and compounds. This is because in solutions and mixtures the substances are not bonded to each other or pure, you can separate and purify substances in solutions and mixtures (via techniques such as distillation, filtering) but you cannot separate compounds as they are bonded together.

Final answer:

In chemistry, elements and compounds are classified as chemical substances. Elements are substances composed of identical atoms, whereas compounds are substances formed from chemically bonded elements.

Explanation:

In the world of chemistry, both elements and compounds are classified as chemical substances. An element is a substance composed of identical atoms, such as hydrogen or iron. A compound, on the other hand, is a substance formed when two or more elements are chemically bonded together, like water (H2O) or carbon dioxide (CO2). It's important to distinguish these from mixtures and solutions, which can contain multiple substances but aren't chemically bonded, therefore, they are not considered chemical substances in the strict sense.

A student records the mass of a piece of iron. The iron is then left outside until it rusts. What type of reaction occurs, and how does the mass of the object after rusting compare with its original mass?

Answers

A student records the mass of a piece of iron. The iron is then left outside until it rusts. The type of reaction that occurs is oxidation reaction. The mass of the object decreases after rusting compared with its original mass.

Answer:

oxidation reaction

Explanation:

Rusting is the oxidation of iron in the presence of air and moisture. Rusting in a chemical change in which iron combines with oxygen to form iron oxide. The molar mass of iron oxide is greater than iron. So the mass of an object after rusting is greater than its initial mass.
