A large marble is dropped in a graduated cylinder with 45 mL of water in it. The water level increased to 61 mL. What is the volume of the marble?​

Answers

Answer 1

Answer:

The answer is 16 mL

Explanation:

The volume of the marble can be found by using the formula

volume = final volume of water - initial volume of water

So we have

volume of marble = 61 - 45

We have the final answer as

16 mL

Hope this helps you

Which has the highest frequency?
X-rays Visible

Answers

Answer:

Radio waves

X-rays Visible

Explanation:

The wavelength of a wave is the difference between successive crests on a wave line. Waves with a very high wavelength have low energy.

Frequency is the number of waves that pass a point per unit of time. The higher the frequency, the higher a wave's energy.

From the given spectrum, wavelength increases from left to right. This puts radio waves as the wave with the longest wavelength. It is also right to say, it has the least energy. Also, frequency decrease from left to right. Gamma rays have the highest frequency in the spectrum. This is followed by x-rays.

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.

How did Thomson's experiment change Dalton's atomic model?
A. Thomson discovered that atoms changed properties when put in

B. Thomson discovered that atoms did not rearrange when forming
compounds.
C. Thomson discovered that atoms of one kind of element could
have different masses.
D. Thomson discovered that the atom contained smaller particles
called electrons.

Answers

Answer:

D. thomson discovered that the atom contains smaller particles called electrons

Thomson discovered that the atom contained smaller particles called electrons. The correct option is D.

What is Dalton's atomic model?

Dalton proposed that all matter is composed of tiny indivisible particles known as atoms, which he envisioned as "solid, massy, hard, impenetrable, movable particle(s)."

Thomson's experiment altered Dalton's atomic model by revealing the existence of smaller particles known as electrons within the atom.

The first part of his theory states that all matter is made up of indivisible atoms. According to the second part of the theory, all atoms of a given element have the same mass and properties.

One of Dalton's most important contributions is that it does not violate several fundamental laws of chemical combination, including the law of definite proportions, the law of multiple proportions, and the law of conservation of mass.

Thus, the correct option is D.

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.

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

[tex]\tt =0.15\times 55+0.85\times 56\\\\=\boxed{\bold{55.85~amu}}[/tex]

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 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
