Answer: Mechanical: Mechanical energy is the ability to do work.

Thermal: Thermal energy refers to the energy contained within a system that is responsible for its temperature.

Chemical:  Energy stored in the bonds of chemical compounds. Chemical energy may be released during a chemical reaction, often in the form of heat.

Electromagnetic: Electromagnetic energy is a form of energy that is reflected or emitted from objects in the form of electrical and magnetic waves that can travel through space.

Electrical: Electrical energy is the power an atom's charged particles have to cause an action or move an object.

Nuclear: Nuclear energy is the energy in the nucleus, or core, of an atom.

How are sex chromosomes different from other chromosomes​
sladkih [1.3K]
<h3>The somatic and sex chromosomes mainly differ in their Ploidy.</h3>

  • Somatic Chromosomes are Diploid (2n)

  • Sex Chromosomes are Haploid (n)

Haploidity of sex chromosomes enables the formation of a diploid zygote after fertilization

<h3>Somatic Chromosomes are homologous in nature while the Sex Chromosomes can be Analogous as in the case of Spermatozoa which bears XY genes </h3>

PLS help, 20 points for you<br><br> I need a Molecular, and Ionic equations:<br> H2CO3 + LiOH -
STatiana [176]

The molecular equation of H₂CO₃ and LiOH:

H₂CO₃ (aq) + 2LiOH (aq) →  Li₂CO₃ (aq)  + 2H₂O (l)

The net ionic equation of the reaction of H₂CO₃ and LiOH:

H⁺ (aq)  + OH⁻ (aq)  →  H₂O (l)

<h3>What are the net ionic equations?</h3>

The net ionic equation of a chemical reaction can be described as an equation that expresses only those ions, elements, or compounds, that directly contributed to that chemical reaction.

The chemical equation for the reaction of H₂CO₃ and LiOH:

H₂CO₃ (aq) + LiOH (aq) →  Li₂CO₃ (aq)  + 2H₂O (l)

The complete ionic equation for the above reaction H₂CO₃ and LiOH is:

2H⁺ (aq) +  CO₃²⁻ (aq) + 2Li⁺ (aq) + 2OH⁻  → 2Li⁺ (aq) + CO₃²⁻(aq) + 2H₂O (l)

In the ionic equation, the Lithium and carbonate ions appear unchanged on both sides of the equation. When we mix the two solutions, neither the Lithium nor carbonate ions participate in the reaction. So Lithium and carbonate ions can be eliminated from the ionic equation.

H⁺ (aq)  + OH⁻ (aq)  →  H₂O (l)

Consider: CO(g) + Cl2 (g) ⇌ COCl2 (g) Kc = 1.2×103 at 395 °C. If the equilibrium concentrations of Cl2 and COCl2 are the same at
ad-work [718]

Answer : The equilibrium concentration of CO in the reaction is, 8.3\times 10^{-4}M

Explanation :

The given chemical reaction is:

CO(g)+Cl_2(g)\rightleftharpoons COCl_2(g)

The expression for equilibrium constant is:

K_c=\frac{[COCl_2]}{[CO][Cl_2]}

As we are given:

Concentration of Cl_2 at equilibrium = Concentration of COCl_2

So,

K_c=\frac{[Cl_2]}{[CO][Cl_2]}

K_c=\frac{1}{[CO]}

1.2\times 10^3=\frac{1}{[CO]}

[CO]=8.3\times 10^{-4}M

Therefore, the equilibrium concentration of CO in the reaction is, 8.3\times 10^{-4}M

Which term identifies the dark smooth areas on surface of the moon
ivann1987 [24]

The dark smooth areas on the surface of the moon is called Maria.

Maria is made up of solidified lava which is a result of volcanic activity on the moon.

When Galileo observed these smooth dark spots on the moon he called them 'mare' which is latin for 'sea'. And the plural form of mare is 'maria'. Unlike Galileo predictions, recent investigations confirm that maria are not oceans but solidified lava.
