1. Calculate the average atomic mass of iron if its abundance in nature is 15%-iron-55 and
85% iron-56

Answers

The average atomic mass of iron : 55.85 amu

Further explanation

The elements in nature have several types of isotopes

Isotopes are atoms whose no-atom has the same number of protons while still having a different number of neutrons.

An atomic mass unit = amu is a relative atomic mass of 1/12 the mass of an atom of carbon-12.

The 'amu' unit has now been replaced with a unit of 'u' only

Atomic mass is the average atomic mass of all its isotopes

atomic mass X = mass isotope 1 . % + mass isotope 2.% ...

The average atomic mass of iron : 55.85 amu

Calculation for average atomic mass:

Isotopes are atoms whose atoms have the same number of protons while still having a different number of neutrons.

An atomic mass unit = amu is a relative atomic mass of 1/12 the mass of an atom of carbon-12.

The 'amu' unit has now been replaced with a unit of 'u' only

Atomic mass is the average atomic mass of all its isotopes.

Atomic mass X = mass isotope 1 *  Mas % + mass isotope 2* Mass %

The average atomic mass of iron:

=0.15 * 55 + 0.85 * 56

=55.85 amu

Thus, the average atomic mass of iron : 55.85 amu

What do eukaryotic cells, prokaryotic cells and viruses all have in common?

Answers

Answer:

Like a prokaryotic cell, a eukaryotic cell has a plasma membrane, cytoplasm, and ribosomes, but a eukaryotic cell is typically larger than a prokaryotic cell, has a true nucleus (meaning its DNA is surrounded by a membrane), and has other membrane-bound organelles that allow for compartmentalization of functions.

What is the mass obtained of Ag from the reaction of 3 moles of AgCl

Given= Zn + 2AgCl —> ZnCl2 + 2Ag

Answers

Answer:

323.7g

Explanation:

Given parameters:

Number of moles of AgCl = 3 moles

Unknown:

Mass of Ag = ?

Solution:

We solve this problem by working from the known to the unknown;

The known here is AgCl;

    From the balanced equation:

              Zn + 2AgCl → ZnCl₂ + 2Ag    

              2 moles of AgCl will produce 2 moles of Ag

              3 moles of AgCl will produce 3 moles of Ag

The mass of Ag will be;

     Mass of Ag  = number of moles x molar mass

Molar mass of Ag = 107.9g/mol

      Mass of Ag = 3 x 107.9  = 323.7g

A student states that photosynthesis is conducted only in plant cells and that cellular respiration occurs only in animal cells. Tell whether the student is correct and why. In your response, be sure to describe both processes and the structures involved. Upload your answer below.

Answers

Answer:

This is correct

Explanation:

This is correct because for photosynthesis you need organelles such as chloroplasts, chloroplasts absorb light energy and convert it into usable energy for plants. Animal cells do not have chloroplasts/similar organelles so  they can't absorb energy from the sun, Animal cells use mitochondria which takes energy from our food and breaks it down into usable energy(such as ATP) to be transported.

During evaporation, what causes certain liquid molecules to become vapor molecules? A. Decreased fluidity A. Increased viscosity A. Decreased kinetic energy A. Increased kinetic energy.

Answers

Answer:

The answer is A. Decreased Fluidity

Explanation:

Taking the test on preformance matters

In evaporation, particles of liquids take energy in the form of sunlight from the surrounding and then convert into vapor phase. Increased kinetic energy causes certain liquid molecules to become vapor molecules.

What is evaporation?

Evaporation is a physical process in which the water in liquid state converts to gaseous state at the temperature below its boiling point. Evaporation happens before the boiling process.

Evaporation causes cooling effect in the surrounding. During summer when water is kept in earthen pot water cools, this is because of the evaporation process.

Evaporation is affected by temperature. As the temperature increases, kinetic energy of liquid molecules also increases and hence the rate of evaporation increases.

Therefore, increased kinetic energy causes certain liquid molecules to become vapor molecules.

A student combines two clear liquid chemicals together in a beaker. When the two chemicals are combined, bubbles are formed, the solution turns blue, and you can see flakes of something forming on the bottom of the beaker. Is this a physical or chemical change? Why?

Answers

Answer:

chemical change

Explanation:

A physical change is one that makes changes to the physical properties of matter. In many cases, the difference is usually reversible. Examples include boiling, melting, freezing, the magnetization of metals, etc.

A chemical change is one in which a new kind of matter is formed. It is usually accompanied by energy changes, i.e., the evolution or absorption of energy in the form of heat or light. This process is not easily reversible. Examples include; combustion, rusting of iron, precipitation, the souring of milk, etc.

From the question given, the combination of two clear liquid in a beaker which results to formation of bubbles and changes in coloration of the solution is a chemical change.

The chemical formula 3NH4 means there are 3 atoms of nitrogen and 4 atoms of hydrogen in each molecule.

What are chemical reaction?

Chemical reaction is defined as a process in which one or more substances, the reactants, are converted into one or more different substances, the products.

A chemical reaction rearranges the constituent atoms of the reactants to create different substances as products.

There are five main types of reactions.

Combination reaction - A combination reaction is a reaction in which two or more substance combine to form a single new substance also known as synthesis reaction.Decomposition reaction - A decomposition reaction is a reaction in which a compounds break down into two or more simpler substance.Single replacement reaction - A single replacement reaction is a reaction in which one element replaces a similar element in a compound.Double replacement reaction - A double replacement reaction is a reaction in which the positive or negative ions of to ionic compounds exchange places from two new compound.Combustion reaction - A combustion reaction is a reaction in which a substance reacts with oxygen gas, releasing energy in the form of heat and light.

Thus, the chemical formula 3NH4 means there are 3 atoms of nitrogen and 4 atoms of hydrogen in each molecule.

Answer:

The answer is 89.70 g

Explanation:

The mass of a substance when given the density and volume can be found by using the formula

mass = Density × volume

From the question

density = 11.34 g/cm³

volume = 7.91 cm³

We have

mass = 11.34 × 7.91 = 89.6994
