In each of the following pairs, circle the form of radiation with the LONGER WAVELENGTH:
A. red light or blue light
B. microwaves or radiowaves
C. infrared radiation or red light
D. gamma rays or UV rays
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

A. How many molecules of sugar are in 20.5 g of sugar?
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.

1 cal = 4.184 J
1kcal = 4184 J
thus, 300 kcal= 4184 × 300
= 1255200J
= 1255.2 kJ
= 1.2552 MJ
What colors are the fireworks in the photo? How do you
think the matter and energy of fireworks of different colors are similar and
different?
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.
What is Matter?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:
Physical change
Explanation:
Mark is pushing a box down the hall. Mark is using 5N to push the box 20m. How much work is Mark doing?
The work by Mark : 100 J
Further explanationWork is the transfer of energy caused by the force acting on a moving object
Work is the product of force with the displacement of objects.
Can be formulated
[tex]\tt W=F\times d[/tex]
W = Work, J, Nm
F = Force, N
d = distance, m
Mark is using 5N to push the box 20 m,
F = 5 N

Answer:
no
Explanation:
pure sodium and chlorine are extremely dangerous, but when combined the result in substance that we use every day. How do you think the properties of sodium and chlorine change when they are combined to make sodium chloride?
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.
Information regarding chlorine: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.

For the n = 3 electron shell, which of the following quantum numbers are valid? Check all that apply.
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.

Human body uses the energy provided from food digestion. Endothermic or exothermic?
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.
What 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.

Which of these elements has an electron configuration of [Kr]5s2?
barium
calcium
rubidium
strontium
Strontium has an electron configuration of [Kr]5s²
Further explanationIn 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 :
element is in period 5 (5 = shell)element is group 2(valence electron =2 and block s) has atomic number 38 (Kr = 36 + 2(valence elektron from 5s²)If we look at the periodic system, the elements that meet the requirements in question are Strontium (Sr)
