When you break an iron magnet into two pieces, you get ____.


two north poles

two south poles

two north poles and two south poles

a piece of iron that is no longer magnetic

Answers

Answer:

two north poles and two south poles

Explanation:

A single magnet has a north pole and a south pole. If it is broken into two pieces, then each of the two pieces will have a north pole and a south pole.

No matter how many times or into how many pieces a magnet is broken, the resulting pieces will have two poles each.

Answer:

Each piece will still have a north pole and a south pole.

The Aufbau Principle describes that
O electrons with the same spin cannot occupy the same orbital.
electrons will occupy single orbitals within and energy level before doubling up
electrons fill lower energy levels first before occupying higher energy levels.
O electrons in the same level have the same amount of energy

Answers

Answer:

electrons fill lower energy levels first before occupying higher energy levels.

Explanation:

The Aufbau's principle describes that electrons fill lower energy levels first before occupying higher energy levels.

In writing the electronic configuration of atoms, the Aufbau's principle is one of the most important principles to consider.

It states that "sublevels with with lower energies are filled up before those with higher energies".

Sublevels do not fill up in numerical order.

Complete the following sentence: In a reaction containing two reactants, if one of the reactants is in excess, the other reactant is known as the ______ reactant.

Answers

Answer:

excess reactant

Explanation:

The excess reactant is the reactant in a chemical reaction with a greater amount than necessary to react completely with the limiting reactant. It is the reactant(s) that remain after a chemical reaction has reached equilibrium.

In a reaction containing two reactants, if one of the reactants is in excess, the other reactant is known as the limiting reactant which decides the yield of the reaction.

What is limiting reactant ?

In a reaction, all the reactants have to be in correct stoichiometry to complete the reaction. To achieve the mole ratio of the reactants is very much important for the completion of a reaction.

If a reactant is insufficient in amount, then the reaction will stop as soon as this reactant is consumed. Hence, this reactant determine the yield of the product. This reactant which is not in correct stoichiometry for the complete reaction is called the limiting reactant.

The reactant which is excess in quantity thus does not have a role in the yield of the reaction is called the excess reactant. Whatever, the concentration of this reactant in extra, the reaction does not proceed after the consumption of limiting reactant.

why are cells small?​

Answers

Answer:

you know what i really dont know but imagine if they were huge

Explanation:

Because if a cell grows beyond a certain limit, not enough material will be able to cross the membrane fast enough to accommodate the increased cellular volume.
They are also small so they can maximize the ratio of surface area to volume. Smaller cells have a higher ratio which allows more molecules and ions move across the cell membrane per unit of cytoplasmic volume.

basically cells are small because they need to be able to get the nutrients in and waste out quickly.

A 5.0 g sample of metal was heated to a temperature of 100.0 °C then placed into a calorimeter containing 35 mL of water at 20.0°C.
The final temperature was 26.5°C What is the specific heat capacity of the metal?

Answers

The specific heat capacity of the metal : c = 2.59  J/g °C

Further explanation

Given

5 g sample

35 ml water = 35 g

Required

The specific heat capacity of the metal

Solution

Heat can be formulated :

Q = m.c.Δt

Q in = Q out

Q absorbed = Q released

Q water = Q metal

35 g x 4.184 J/g °C x (26.5-20)= 5 x c x (100-26.5)

951.86 J = 367.5 x c

c = 2.59  J/g °C

How to calculate the number of molecules in 18g of H2O

Answers

We, know molecular mass of water is, M = 16 g/mol .

Given mass of water, m = 18 g.

We know, number of moles is given by :

[tex]n = \dfrac{18\ g}{16 \ g/mol}\\\\n = 1.125\ moles[/tex]

Now, 1 mole of any compound contains 6.022 × 10²³ molecules.

So, number of moles in 1.125 moles of water is 1.125 × 6.022 × 10²³ =

6.77 × 10²³ molecules.

Hence, this is the required solution.

What does the pH of a solution represent?


A. The pH represents the partial pressure of hydrogen gas.


B. The pH tells how quickly a reaction reaches equilibrium.


C. The pH indicates how acidic or basic a solution is.


D. The pH is an indicator of the salt content of a solution.

Answers

Answer:

The pH indicates how acidic or basic a solution is.

Explanation:

i just took the test and got it right.

pH of a solution is the measure of how acidic or basic the solution is. It is determined based on the H+ ion concentration in the solution. Hence, option C is correct.

What is pH?

pH of a solution is the measure of the H+ ion concentration in a solution. It determines the acidity or basicity of the solution. Mathematically it is the negative logarithm of H+ ions concentration.

pH = - log [H+]

A pH scale can be used to determine the acidity or basicity of a solution. If the basicity is 7, then the solution is neutral. If the pH is less than 7 then the solution is acidic and a pH above 7 is basic solution.

Red- green color in pH scale represent the acidic solution where green is neutral and cyan to dark blue color is given by bases. Using a litmus paper the acidity can be checked based on these color change.

Explanation:

Landslides are exceptionally destructive. Homes may be destroyed as hillsides collapse. Landslides can even bury entire villages. Landslides may create lakes when the rocky material dams a stream.

The type of mass movement is the most destructive landslide.

What is landslide?

Several forms of mass wasting that may include a wide range of ground movements, such as shallow or deep-seated slope failures, rockfalls, mudflows, and debris flows are known as landslips or landslide.

Sometimes more than one type of movement occurs within a single landslide, and analysis of each requires detailed interpretation of landforms and geological sections.

Landslides are exceptionally destructive. Homes may be destroyed as hillsides collapse. Landslides can even bury entire villages. Landslides may create lakes when the rocky material dams a stream.

There are measures that can be taken to reduce the potential for a landslide to occur, such as steep slope reinforcement, installing structures using pile foundations and checking surface drainage. The easiest way to prevent a landslide is to avoid building in areas that are – or might become – prone to landslides.

Given options are-

creep

erosion

Radio waves are used to transmit information on various channels. What is the wavelength of a radio wave having the frequency of 5.40 × 1010 Hz?

1. Analyze the Problem

ν = and c = Unknown: λ =

You know that because radio waves are part of the electromagnetic spectrum, their speed, frequency, and wavelength are related by the formula c = λν.

Answers

Answer:

5.56×10¯³ m

Explanation:

From the question given above, the following data were obtained:

Frequency (v) = 5.4×10¹⁰ Hz

Wavelength (λ) =?

The velocity of electromagnetic wave, frequency and wavelength are related according to the equation:

Velocity (c) = wavelength (λ) × frequency (v)

c = λv

With the above formula, the wavelength of the radio wave can be obtained as follow:

Frequency (v) = 5.4×10¹⁰ Hz

Wavelength (λ) =?

Velocity (c) = 3×10⁸ m/s

c = λv

3×10⁸ = λ × 5.4×10¹⁰

Divide both side by 5.4×10¹⁰

λ = 3×10⁸ / 5.4×10¹⁰

λ = 5.56×10¯³ m

Thus, wavelength of the radio wave is 5.56×10¯³ m
