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 proton number of barium (Ba) is 56. It is in Group II of the periidic table how many electrons would you expect a barium atom to contain in its outer energy level?

Answers

Answer:

A barium atom would be expected to contain 2 electrons in its outer energy level.

Explanation:

The columns of the periodic table are called groups. There are eighteen groups, numbered from 1 to 18.

The elements of each group have the same number of electrons in their last atomic shell, which is why they have similar chemical properties, because the chemical properties of chemical elements are strongly related to the electrons located in the last atomic shell.

That is, in a group, the chemical properties are very similar, because all the elements of the group have the same number of electrons in their last or last shells.

A barium atom would be expected to contain 2 electrons in its outer energy level.

over the opening. The bottle with the balloon is then placed in very hot water and the balloon inflated. Why
did the balloon inflate?

Answers

Answer:

hot air rises and expanded the balloon

Explanation:

thats it.

The hot air rises and expanded the ballon. This is as the air in the bottle cools down, the molecules of the air slow down and take up less space because they move closer together. The air then moves out of the balloon and back into the bottle, causing the balloon to deflate.

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.

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

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.

Answer:

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.

A student increases the temperature of a 673 cm^3 balloon from 275 K to 460 K.

Assuming constant pressure, what should the new volume of the balloon be?

Round your answer to one decimal place.

Answers

Answer:

1125.75 cm³

Explanation:

We are given;

Initial volume; V1 = 673 cm³

Initial temperature; T1 = 275 K

Final temperature; T2 = 460 K

From Charles law, we can find the new volume from;

V1/T1 = V2/T2

V2 = (V1 × T2)/T1

V2 = (673 × 460)/275

V2 = 1125.75 cm³

The complete combustion of acetic acid, HC2H3O2(I) to form water, H2O(I), and CO2(g), at constant pressure releases 871.7 kJ of heat per mol of acetic acid.
Write a balanced thermochemical equation if 5.0g of acetic acid will be used in the reaction.
HC2H3O2(I) + O2 --- H2O(I) + CO2(g) H= -871.7 kJ

Answers

Answer:

HC2H3O2(I) + O2(g) ---> H2O(I) + CO2(g) ΔH= -72.35 kJ

Explanation:

We know that 5.0 g of acetic acid will contain, 5.0g/60 g/mol = 0.083 moles of acetic acid

Now from the reaction equation;

1 mole of acetic acid evolved -871.7 KJ of heat

0.083 moles of acetic acid will evolve 0.083 * -871.7 = -72.35 KJ

For 5.0 g of acetic acid, we can write;

HC2H3O2(I) + O2(g) ---> H2O(I) + CO2(g) ΔH= -72.35 kJ

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
