How many grams are equal to 3.46 moles of iodine
?
875.38 g are equal to 3.46 moles of iodine.
What is moles?The mole is the SI basic unit of substance quantity, with the sign mol. The amount of substance in an object or sample is defined as the number of elementary entities of that substance.
It is given that n = 3.46, molar mass of iodine = 253 g/mol.
Moles can be expressed as:
Moles = mass /molar mass
3.46 mol= mass / 253 g/mol.
mass = 253 g/mol ×3.46 mol
mass = 875.38 g.

How do atoms make molecules?
Explanation:
Atoms can join together - they form bonds together - to make MOLECULES. ... For example, a hydrogen atom forms one bond, an oxygen atom forms two, and carbon forms four bonds. Look at that molecule of water again - each hydrogen has one bond, and the oxygen in the middle has two bonds. Molecules can be much bigger.

What is Redox Reaction ?Redox is a type of chemical reaction in which the oxidation states of substrate change.
Oxidation is the loss of electrons or an increase in the oxidation state of a chemical or atoms within it.
Reduction is the gain of electrons or a decrease in the oxidation state of a chemical or atoms within it
Given Equation ;
Cu + HNO₃ → Cu(NO₃)₂ + NO + H₂O
The first step is to write the oxidation numbers for each atoms in the given equation
Cu0 + H⁺¹N⁺⁵O⁻²₃ → Cu⁺²(N⁺⁵O⁻²₃)₂ + N⁺²O⁻² + H⁺¹₂O
Identify the oxidizing and reducing agent
OXIDATION ---Cu0 → Cu⁺²(N⁺⁵O⁻²₃)₂ + 2e- REDUCTION---H⁺¹N⁺⁵O⁻²₃ + 3e- → N⁺²O⁻²Balance equation in half reaction
Cu0 + 2 HNO₃ → Cu⁺²(N⁺⁵O⁻²₃)₂ + 2e-
H⁺¹N⁺⁵O⁻²₃ + 3e- → N⁺²O⁻²
Now balance the charge
Cu0 + 2HNO₃ → Cu⁺²(N⁺⁵O⁻²₃)₂ + 2e- + 2H+
H⁺¹N⁺⁵O⁻²₃ + 3e- + 3H+ → N⁺²O⁻²
Balance the oxygen atom
Cu0 + 2HNO3 → Cu+2(N+5O-23)2 + 2e- + 2H+
H+1N+5O-23 + 3e- + 3H+ → N+2O-2 + 2H2O
Make electron gain equivalent to electron lost.
3Cu0 + 6HNO3 → 3Cu+2(N+5O-23)2 + 6e- + 6H+
2H+1N+5O-23 + 6e- + 6H+ → 2N+2O-2 + 4H2O
Complete reaction
3Cu0 + 8H+1N+5O-23 + 6e- + 6H+ → 3Cu+2(N+5O-23)2 + 2N+2O-2 + 6e- + 4H2O + 6H+
Simplify the equation
3Cu0 + 8H+1N+5O-23 → 3Cu+2(N+5O-23)2 + 2N+2O-2 + 4H2O
Final equation
3Cu + 8HNO₃ → 3Cu(NO₃)₂ + 2NO + 4H₂O

Answer:
0.62 molesExplanation:
To find the number of moles in a substance given it's number of entities we use the formula
[tex]n = \frac{N}{L}\\[/tex]
where n is the number of moles
N is the number of entities
L is the Avogadro's constant which is
6.02 × 10²³ entities
From the question we have
[tex]n = \frac{3.73 \times {10}^{23} }{6.02 \times {10}^{23} } = \frac{3.73}{6.02} \\ = 0.619601...[/tex]

Answer:
wavelength decreases, the frequency increases
Explanation:
In the electromagnetic spectrum, as the wavelength decreases, the frequency increases.
The wavelength of the wave is the distance between successive troughs and crests along the wave train.
Frequency of the wave of the number of waves that passes through a point per unit of time.
On an electromagnetic wave, as the wavelength decreases the frequency increases. Also, as the wavelength increases the frequency decreases.amino acid is to protien as?

Answer:
Seismic waves
Explanation:
Scientists study earth's interior using seismic waves. These waves are produced during an earthquake.
The waves have very unique properties that makes them useful for studying the subsurface. Two types of seismic waves are predominantly used. P -waves are the primary waves that passes through any mediumS -waves are the secondary waves that passes only through solids Using these properties, scientists can study the earth's interior.The pressure in a cylinder of nitrogen continuously decreases as a gas is released from it. On the other hand, a cylinder of propane maintain the constant pressure as propane is released. Explain this difference in behavior
Answer:
Explanation:
Nitrogen gas in nitrogen cylinder is in gaseous form only . So when gas is released , pressure decreases because moles of gas in the cylinder decreases .
Propane gas in cylinder is in liquified form . The gas is partially in gaseous and liquid form . So when gas is released outside , pressure decreases inside but due to low pressure , some liquid form is converted into gaseous form which restores the pressure of gas inside cylinder . Hence , the pressure of gas remains unchanged inside cylinder.

A candle weighs 25 grams before burning. After burning for 10 minutes, the candle now weighs 17 grams. Using the Law of Conservation, explain how this is possible.
Explanation:
These are some unaccounted mass that was involved.
According to the law of conservation "matter is neither created nor destroyed but can be combined with one another".
The rule applies to all substances with no exception When burning a candle, a phase change process is going on. Some candle part of the candle occur in molten form whereas the other part is a solid. In this experiment, the molten wax was not taken into consideration. This accounted for the mass deficit.Water in a beaker measures 250 milliliters. A rock is completely submerged in the water. The water level now reads 375 milliliters. What is the volume of the rock in cubic centimeters? Explain your answer.PLEASE HELP ASAP
Answer:
Volume of the rock = 125 cubic centimetres
Explanation:
Given:
Water in beaker = 250 millilitres
Water in beaker after rock = 375 millilitres
Find:
Volume of the rock
Computation:
Volume of the rock = Water in beaker after rock - Water in beaker
Volume of the rock = 375 - 250
Volume of the rock = 125 millilitres
1 millilitres = 1 cubic centimetres
So,
Volume of the rock = 125 cubic centimetres
Answer:
The answer is 125 cubic meters
Explanation:
Because you subtract 375-250 and get 125
Answer=125
Each of the models shown represents a magnesium atom. Which models show the same isotope of magnesium? P, Q, and R
P and Q
P and R
Q and R
Answer:
P and Q
Q and R
Explanation:
To begin, we must bear in mind the meaning of isotope.
Isotopes are atoms having the same atomic number (i.e proton) but different mass number due to the difference in the neutron number present in the atoms involved.
Thus, we shall write out the number of protons, neutrons and electrons present in the model given above. This is given:
Model P:
Proton = 12
Neutron = 13
Electron = 13
Model Q:
Proton = 12
Neutron = 12
Electron = 13
Model R:
Proton = 12
Neutron = 13
Electron = 12
From the above data, we can say that:
1. P and Q are isotope since they have different Neutron number.
2. P and R are not isotope since they have the same Neutron number.
3. Q and R are isotope since they have different Neutron number.

Which of the following states of matter has a definite volume
Answer:
Solid and Liquids

Solid has both definite shape and volume
It's stays on what is there natural appearance.. while
Liquid has definite volume but has indefinite shape
Answer:
[tex]\boxed {\boxed {\sf Solids \ and \ liquids}}[/tex]
Explanation:
Let's review the 3 main states of matter:
Solid:
Particles vibrate, but are stationary. The solid doesn't change under normal conditions. Definite shape and volumeLiquid:
Particles flow and glide. The liquid fills the container. Indefinite shape, definite volumeGas:
Particles fly around rapidly. The gas fills it's container and is very compressible. Indefinite shape and volumeSo, we see that the 2 states of matter with definite volume are solids and liquids.
