Explanation:

Glucose (C₆H₁₂O₆) is an electrolytes hence it conduct electricity.

Therefore,

Option B is correct.

Answer:

The valid quantum numbers are l=0, l=-2 and l= 2.

Explanation:

Given that,

n = 3 electron shell

Suppose, the valid quantum numbers are

l = 3

m = 3

l = 0

m = –2

l = –1

m = 2

We know that,

The value of n = 3

Principle quantum number :

Then the principal quantum number is 3. Which is shows the M shell.

So, n = 3

Azimuthal quantum number :

The azimuthal quantum number is l.

[tex]l=0,1,2[/tex]

Magnetic quantum number :

The magnetic quantum number is

[tex]m=-2,-1,0,1,2[/tex]

Hence, The valid quantum numbers are l=0, l=-2 and l= 2.

Answer: I = 0  m = -2 m = 2

Explanation: Edge.

the correct answers to the second part of this are:

n = 1, I = 0, m = 0

n = 3, I = 0, m = 0

n = 5, I = 4, m = -3

Answer:

All of these examples are physical changes.

Explanation:

Physical changes are changes affecting the form of a chemical substance, but not its chemical composition.

Answer:

The sum of potential energy and macroscopic kinetic energy is called mechanical energy and stays constant for a system when there are only conservative forces (no non-conservative forces). The more mass a moving object has, the more kinetic energy it will possess at the same speed.

Answer: Mechanical energy

Explanation: The more mass a moving object has, the more kinetic energy it will possess at the same speed

Answer:

Explanation:

chlorine has 7 valence electrons while sodium has 1. on their own, they are very reactive elements. a full valence electron shell has 8 electrons, so when elements combine and have 8 electrons in their outer shell, they are not reactive. when sodium and chlorine are combined to form sodium chloride (table salt), it is no longer dangerous. the number of valence electrons changes its reactivity and how it combines.

The properties of sodium and chlorine change when they are combined to make sodium chloride should be explained below.

chlorine comprises of 7 valence electrons while on other hand, sodium has 1.  A full valence electron shell contains the 8 electrons, so when elements combine and have 8 electrons in their outer shell, they are not reactive.

Explanation:

All three can become negative versions: negative ions

Answer:

It is going to be D because Group 1 A and 2 A are s block elements which are METALS, also they are not halogens as the 7 A group is called halogens, Plus they give +1 oxidation state so Correct answer is D as they are group 1 A elements so they have only one valence electron in their valence shell

Answer:

By definition, one mole (one gram molecular weight) of any substance, contains Avogadro’s number of particles; atoms if you are discussing an element, or molecules if a compound. Avogadro’s number has been determined by several methods, all of the accepted values lie within a range of +-1% about the value of 6.022045 x 10^23/gm. That is a large number, in this case approximately; 602,204,500,000,000,000,000,000 molecules of glucose.

Answer:

The heat and light released by fire comes from the breaking of chemical bonds. ... The mass of each molecule, before burning, exceeds the total mass of its atoms by a tiny amount that is equivalent (through E=mc²) to the total energy of all its atomic bonds.

Explanation:

Strontium has an electron configuration of [Kr]5s²

In an atom there are levels of energy in the shell and sub shell  

This energy level is expressed in the form of electron configurations.  

Writing electron configurations starts from the lowest to the highest sub-shell energy level. There are 4 sub-shells in the shell of an atom, namely s, p, d and f. The maximum number of electrons for each sub shell is  

s: 2 electrons  

p: 6 electrons  

d: 10 electrons and  

f: 14 electrons  

From an electron configuration of [Kr]5s² can be concluded :

If we look at the periodic system, the elements that meet the requirements in question are Strontium (Sr)

Answer:

1255200J

Explanation:

1 cal = 4.184 J

1kcal = 4184 J

thus, 300 kcal= 4184 × 300

= 1255200J

= 1255.2 kJ

= 1.2552 MJ

Answer:

Shortly after, the electron will fall back down to a lower energy level, releasing energy in the form of light. Therein lies the key to colorful fireworks!

The matter and energy of fireworks simply rely on the flow of electrons from the ground stage to the excitatory stage.

Matter may be defined as any sort of substance that is constructed of numerous types of particles that occupy physical space and possess inertia. In simple words, matter may be characterized as anything which occupies space and has mass.

When the electrons move from the ground stage to the excitatory stage, they require a significant amount of energy in any form. But when they fall back to the ground stage from the excitatory stage, they liberates energy.

The same principle is applied in the colorful observation of fireworks. The stored energy is released and different colors of fireworks become visible.

Therefore, the matter and energy of fireworks simply rely on the flow of electrons from the ground stage to the excitatory stage and vice-versa.

Answer: different

Explanation: There are 20 different amino acids.

Answer:

Endothermic

Explanation:

Exo is outside so exothermic would be outside the body

The carbohydrates are break down into glucose. Then glucose combines with oxygen in the cells and provides energy. Hence, digestion is an exothermic process.

Food digestion produces heat. This happens as a result of the organism releasing heat during meal digestion. A process that releases heat is exothermic.

Heat is released during an exothermic reaction, raising the temperature of the immediate environment. The environment is cooled through an endothermic process that absorbs heat.

Glucose is created by the breakdown of these carbs. In the cells of our body, this glucose interacts with oxygen to produce energy. So, the process of digesting is exothermic.

Chemical processes involved in food digestion disassemble large food molecules into smaller, more manageable "building block" components.

Thus, Human body uses the energy provided from food digestion is exothermic process.

Answer:

In the first one in a it is red light in b it is radio waves in c it is infrared radiation and d is UV radiation

Explanation:

The forms of radiation from the pairs listed that have longer wavelength are :

A) Red light

B) Radio waves

C) Infrared radiation

D) UV rays

Red light have a wavelength between 650 to 720 nm while a Blue light has a wavelength of 380nm to 500nm which makes it to produce a high energy  visible light.( HEV ) light. therefore the Red light has a longer wavelength.

The wavelength of a microwave is approximately  30 centimeters to 1 millimeter, which makes it shorter than the wavelength of a radio wave ( shortest wavelength in the electromagnetic spectrum.

Hence we can conclude that The forms of radiation from the pairs listed that have longer wavelength are A) Red light B) Radio waves C) Infrared radiation D) UV rays
