Because the offspring gets all of the parent’s traits since there is only one parent involved in asexual reproduction.

How can equilibrium of a closed system chemical reaction be disturbed? Select all that apply.

charle [14.2K]

The correct answers are :

Changing the volume of the system.

Changing the temperature of the system.

Equilibrium will remain unaffected if the concentration of products and reactants are kept the same, and the temperature of the system is kept constant.

As the system is closed, we cannot add or remove products or reactants.

Change in temperature will shift the chemical equilibrium towards the reactant or product depending on whether the reaction is exothermic or endothermic.

Also change in volume will shift the chemical equilibrium of a chemical reaction if the reactants or products or both are gases.

Which answer is an isotope of 40/20x? <br><br> Question Pictured here:

Nesterboy [21]

An isotope of ₂₀⁴⁰X ⇒₂₀⁴⁴X

<h3>Further explanation </h3>

The elements in nature have several types of isotopes

Isotopes are atoms that have the same number of protons and a different number of neutrons.

So Isotopes are elements that have the same Atomic Number (Proton)

In the following element notation,

$\large {{{A} \atop {Z}} \right X}$

X = symbol of elemental atom

A = mass number

= number of protons + number of neutrons

Z = atomic number

= number of protons = number of electrons, on neutral elements

For symbol of isotope X :

₂₀X⁴⁰ : atomic number = 20, mass number = 40

A. ₄₀²⁰X : atomic number = 40, mass number = 20, neutrons=20

B. ₂₀⁴⁰X²⁺ : atomic number = 20, mass number = 40, neutrons=20

C. ₂₁⁴⁰X : atomic number = 21, mass number = 40, neutrons=19

D. ₂₀⁴⁴X : atomic number = 20, mass number = 44, neutrons=22

Pairs

BabaBlast [244]

Atoms are made up of protons, neutrons, and electrons.

Energy can be neither created nor destroyed.

Water freezes at 0°C

If a piece of platinum is placed in acid, it will not react.

<h3>What are the correct pairing of the given terms?</h3>

The correct pairing of the given terms are obtained from the given options as follows:

Atoms of elements contains three sub-atomic particles which are protons, neutrons, and electrons.

Energy is the ability to do work.

According to the law of conservation of energy, Energy can be neither created nor destroyed.

Water is a liquid which freezes at 0°C.

Therefore, Water freezes at 0°C.

Platinum is a metal which is less reactive than hydrogen, Hence, it cannot displace hydrogen from acids.

Hence, if a piece of platinum is placed in acid, it will not react.

In conclusion, the correct pairing gives the correct description of the properties of the given terms.
