Required

Balanced equation

Solution

Convert to skeleton equation

Na₂C₂O₄(aq) + Pb(NO₃)₂⇒PbC₂O₄(s) + NaNO₃(aq)

Balanced equation

Give a coefficient

Na₂C₂O₄(aq) + aPb(NO₃)₂⇒bPbC₂O₄(s) + cNaNO₃(aq)

Make an equation

C, left = 2, right =2b⇒2b=2⇒b=1

Na, left = 2, right = c⇒c=2

O, left = 4+6a, right = 4b+3c⇒4+6a=4b+3c⇒4+6a=4.1+3.2⇒6a=6⇒a=1

The equation becomes :

Na₂C₂O₄(aq) + Pb(NO₃)₂⇒PbC₂O₄(s) + 2NaNO₃(aq)

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.

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.

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.

Transition elements are known to have variable oxidation states whereas, alkali metals have an oxidation state of +1. Transition metals belong the d-block on the periodic table whereas alkali metals are found in the first group on the periodic table.

what’s the correct answer !!

Answers

Answer:

From my side the correct option is "A"

Explanation:    Reasons for its correction are ,

1)  Highly reactive: Nanoparticles are therefore extremely unstable and easily change themselves or react with active substances to reach a relatively stable state in some cases. This causes desired changes or undesired changes to nanoparticles and thus makes them exhibit a high reactivity and a poor stability.

2)Small size:  Nanotechnology can provide rapid and sensitive detection of cancer-related molecules, enabling scientists to detect molecular changes even when they occur only in a small percentage of cells. Nanotechnology also has the potential to generate entirely novel and highly effective therapeutic agents.

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

Answers

Answer:

C

Explanation

On the reactants side there is 4 Hydrogen atoms in total and two oxygen atoms on the left however on the right there is two hydrogen atoms and one oxygen atom. Leaving this equation unbalanced

The equation that is NOT balanced is [tex]\rm 2H_2 + O_2\rightarrow H_2O[/tex]. The correct answer is option C.

In a balanced chemical equation, the number of atoms of each element on the reactant side must be equal to the number of atoms of each element on the product side.

In equation A, there are 4 hydrogen atoms and 2 oxygen atoms on both the reactant and product sides, so it is balanced.In equation B, there are 4 hydrogen atoms and 2 oxygen atoms on both the reactant and product sides, so it is balanced.In equation C, there are 4 hydrogen atoms and 2 oxygen atoms on the reactant side, but only 2 hydrogen atoms and 1 oxygen atoms on the product side. Therefore, it is not balanced.In equation D, there are 8 hydrogen atoms and 4 oxygen atoms on both the reactant and product sides, so it is balanced.

In conclusion, equation C.  [tex]\rm 2H_2 + O_2\rightarrow H_2O[/tex] is the one that is NOT balanced. It has an unequal number of oxygen atoms on the reactant and product sides.

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

Explanation:

Typically protons cannot be removed from the atom. Removing protons from an atom will completely change the atom as it will become another element entirely.

In an atom, protons are held by strong nuclear forces.

Within an atom, protons are the positively charged particles. Together with the neutrons, they are found in the nucleus of an atom. The number of protons within an atom is the atomic number of the atoms and it determines the nature and type of atom it is. Protons cannot be removed from an atom due to the strong binding force holding them together in place.
