A clear explanation of misconception of sugar is energy and energy is sugar is below.
What are sugars?Sugars are the disaccharide carbohydrate, it means they are formed by the combination of two monosaccharides.
One of the component of the sugar is glucose and we know that glucose is the source of energy in our body. So, sugars are naturally present in many food substance which in turn breaks down in the glucose and their composite constituent and releases energy. But we can never compare sugar as the main source of energy or equivalent to energy.
Hence, Energy means sugar is the misconception.

Explanation:
After decaying for 48 hours, one-sixteenth (1/16) of the original mass of a radioisotope sample remains unchanged. What is the half-life of this radioisotope?
The half-life of this radioisotope : 12 hr
Further explanationThe atomic nucleus can experience decay into 2 particles or more due to the instability of its atomic nucleus.
Usually radioactive elements have an unstable atomic nucleus.
General formulas used in decay:
[tex]\large{\boxed{\bold{N_t=N_0(\dfrac{1}{2})^{t/t\frac{1}{2} }}}[/tex]
t = duration of decay
t 1/2 = half-life
N₀ = the number of initial radioactive atoms
Nt = the number of radioactive atoms left after decaying during T time
t=48 hr
[tex]\tt \dfrac{Nt}{No}=\dfrac{1}{16}[/tex]
The half-life :
[tex]\tt \dfrac{1}{16}=\dfrac{1}{2}^{(48/t\frac{1}{2} )}\\\\(\dfrac{1}{2})^4=(\dfrac{1}{2})^{48/t\frac{1}{2}}\\\\4=48/t\frac{1}{2}\\\\t\frac{1}{2}=12~hr[/tex]

Why do elements form an ionic bond
Answer:
An ionic bond is formed when a metallic element and a non-metallic element form a compound.
Explanation:
As you may know, each atom contains a set amount of electrons. For example, Hydrogen has one electron, helium has two electrons, lithium has three electrons and so on.
Electrons come in shells. The first shell can hold 2 elections at most, and each shell past this point can hold 8 electrons. When an atom has a filled outer shell, it is considered stable. (This so why the noble gases are unreactive- they have a full outer shell of electrons.)
This is why compounds can form- it is the chemical bonding of 2 or more chemical elements: take NaCl, sodium chloride, or SO2, sulphur dioxide.
You specifically asked about ionic bonds. Ionic bonds, as expressed above, form between a compound of a metallic and non metallic element.
Let's take sodium chloride as an example. Sodium has 1 electron in its outer shell and chlorine has 7. Both need a full outer shell to become stable. Because of this, the sodium atom loses its only electron in its outer shell to become a sodium ion and the chlorine atom gains the electron to become a chlorine ion as well. Because of this, both ions have a full outer shell, rendering them stable.
Now, because the sodium ion is short of one electron, it has more protons than electrons, resulting in it having a positive charge. The chlorine ion is the opposite, having a negative charge.
Ice cube trays hold about 350 grams of water. If the water comes out of the faucet at 37 degrees celcius, how much evergy do I have to remove to freeze the ice cubes?
Answer:
-171.79 KJ
Explanation:
We must keep in mind that water freezes at 0 degrees centigrade
Recall that heat lost during freezing can be obtained from;
H = mc(θ2 - θ1)
m = mass of the water = 350 g/1000 = 0.35 Kg
c = specific heat capacity of water = 4,200 J/kg°C
θ2 = final temperature = 0°C
θ1 = initial temperature = 37°C
H= 0.35 * 4,200 * (0 - 37)
H = -54390 J = -54.39 KJ
Energy given out when 1 mole of water freezes at its freezing point = -6.04 kJ
For 350 g of water; 350 g/18 g/mol * -6.04 kJ = -117.4 kJ
Hence total energy removed = (-54.39 KJ) + (-117.4 kJ) = -171.79 KJ

1. 532 mol
2. 106 mol
3. 32 × 1025 mol
4. 266 mol
Answer:
532 moles of O atoms.
Explanation:
Given data:
Number of moles of oxygen atom present = ?
Number of molecules of N₂O₅= 6.41×10²⁵ molecules
Solution:
First of all we will calculate the number of moles of N₂O₅.
1 mole = 6.022×10²³ molecules
6.41×10²⁵ molecules × 1 mol /6.022×10²³ molecules
106.4 mol
Number of atoms of O:
1 mole of N₂O₅ contain 5 moles of O atoms.
106.4×5 = 532 mol
What happens to air pressure as you move upward into the atmosphere?
it increases
it decreases
it remains constant or stays the same
it fluctuates and increases and decreases
Answer:
Pressure decreases with increasing altitude
Explanation:
At higher elevations, there are less air moecules.
Explanation:
The pressure exerted by the air in the atmosphere is greatest at Earth's surface and falls as altitude increases. The reason is that density and depth of the atmosphere are greatest at sea level and decline with increasing altitude.

When the first American astronauts were planning to walk on the Moon, they knew that the gravity on the Moon was less than the gravity on Earth. With this information, what did the astronauts expect to be MOST different on the Moon? Select one: a. their mass b. their height c. their weight d. their volume
Answer:
Their weight.
Explanation:
Weight is the measurement of gravity pushing you down, so with less gravity there would be less weight.
The astronauts expect their weight to be different on the Moon
Definition of weightWeight is simply defined as the gravitational pull of the earth on an object. It is measured in Newton.
Description of weightThe weight of an object varies with location because of gravity.
The weight of an object is related to it's mass according to the following equation:
Weight = mass × Acceleration due to gravity
Since the gravity of the Moon is lesser than that of the Eearth, the astronauts certainly knew that their weight will be different on the Moon.

Problem #2: A photographic "stop bath" contains 160mL of pure acetic acid,
HC H20 in 650ml solution. What is the v/v concentration of acetic acid
in the stop bath?
Answer:
100008
Explanation:
The v/v concentration of 160ml pure acetic acid in 650ml solution is 24.61 %.
There is 160ml of pure acetic acid in the 650 ml solution of acetic acid.
The volume/volume concentration of acetic acid can be calculated as:
Volume/Volume = [tex]\rm \frac{volume\;of\;acetic\;acid}{Volume\;of\;solution}\;\times\;100[/tex]
v/v = [tex]\rm \frac{160}{650}\;\times\;100[/tex]
v/v = 0.2461 [tex]\rm \times[/tex] 100
v/v = 24.61 %
The concentration of pure acetic acid in the 650 ml solution is 24.61 % (v/v).

3. You have a sample of fluorine to analyze. The sample is made up of neutral atoms. Using the information in the diagram at the right, determine the number of protons, neutrons, and electrons found in each atom of your sample. Explain your answer.
Answer:
1. Proton number is 9
2. Neutron number is 10
3. Electron number is 9
Explanation:
The following data were obtained from the question:
Atomic number = 9
Mass number = 19
1. Determination of the number of protons.
The atomic number of an element is simply the number of protons present in the atom of that element. Mathematically, it is expressed as:
Atomic number = proton number
Atomic number = 9
Proton number = atomic number = 9
Thus, the proton number is 9
2. Determination of the Neutron number.
Mass number = 19
Proton number = 9
Neutron number =?
Mass number = Proton + Neutron
19 = 9 + Neutron
Collect like terms
19 – 9 = Neutron
10 = Neutron
Thus, the Neutron number is 10.
3. Determination of the number of electrons.
Since the sample is made up of neutral atoms, the number of protons and electrons are equal i.e
Electron number = Proton number
Proton number = 9
Electron number = Proton number = 9
Thus, electron number is 9
Using the information given in the diagram, the number of protons, neutrons and electrons in an atom of the Fluorine-19 sample are 9, 10 and 9 respectively.
Given :
Atomic number = 9Atomic mass = 19The number of protons = Atomic number
Hence, the number of protons = 9
2).
Recall :
Atomic mass = proton number + neutron numberSubstituting the values into the formula :
19 = 9 + neutron number
neutron number = 19 - 9
neutron number = 10
3.)
The number of electrons = proton number + charge
Since, the atom contains neutral atom, then charge = 0
Number of electrons = 9 + 0
Number of electrons = 9
Therefore, the Number of protons, neutrons and electrons are 9, 10 and 9 respectively.
