Can someone help me with this?

Answer:

Lemon juice baking soda and vinegar

Explanation:

there is nothing with which it can react

Explanation:

The limiting reactant(s) prevents a reaction from continuing because there is none left.

Identification of the limiting reactant makes it possible to calculate the theoretical yield of a reaction. The reason there is a limiting reactant is that elements and compounds react according to the mole ratio between them in a balanced chemical equation.

The reactant that is consumed first and limits the amount of product(s) that can be obtained is the limiting reactant. To identify the limiting reactant, calculate the number of moles of each reactant present and compare this ratio to the mole ratio of the reactants in the balanced chemical equation.

Answer:

Isotopes are forms of a chemical element that have the same atomic number but differ in mass. 16O → 8 protons + 8 neutrons; a “light” oxygen); The relative amounts are expressed as either 18O/16O or δ 18O Oxygen - 18 (aka 18O → 8 protons + 10 neutrons; a “heavy” oxygen).

In the experiment to measure the heat absorbed by a material placed in

the Sun, we have;

The possible experiment is with regards to the factors that influence energy from the Sun

The factors investigated are;

The type of material and the angle of lighting (insulation) affects the absorption of heat

The independent variable is the variable that is the cause of the effect

measured in the experiment.

It is the variable that the researcher has control over or controls and

varies during the experiment to produce the measured effect.

In the above experiment, the independent variable are either ;

The dependent variable is the variable that is under test or that is being measured.

The controlled variable is the variable that remains the same or is held

constant during the experiment and can be used as reference to

compare the dependent variable.

Explanation:

13 electrons

So... for the element of ALUMINUM, you already know that the atomic number tells you the number of electrons. That means there are 13 electrons in a aluminum atom. you can see there are two electrons in shell one, eight in shell two, and three in shell three.

7 electrons

So... for the element of NITROGEN, you already know that the atomic number tells you the number of electrons. That means there are 7 electrons in a nitrogen atom. Looking at the picture, you can see there are two electrons in shell one and five in shell two.

Answer:

there is one carbon atom and there are two oxygen atoms. So, in total there are three atoms.

Question:

Leon made a study chart about human-induced changes to the environment.

Environmental Changes Caused by Humans

X Y

Results from introducing harmful substances into the environment

Example: oil spill

Results from natural areas being cleared and replaced by human development

Example: deforestation

Which headings best complete the chart?

X: Habitat Destruction

Y: Pollution

X: Long-Term Changes

Y: Short-Term Changes

X: Short-Term Changes

Y: Long-Term Changes

X: Pollution

Y: Habitat Destruction

Answer:

X: Pollution

Y: Habitat Destruction

Explanation:

From the above question, Leon gave us two variables, X and Y.

The human induced changes were divided into two.

1. Results from introducing harmful substances into the environment

Introducing harmful substances into the environment is also called pollution. And we can represent this as X which is the first variable.

2. Results from natural areas being cleared and replaced by human development.

This description given in number two above whereby land areas are been cleared and replaced by human development has a negative effects on the environment because the vegetation which includes the trees are been cut down and living organisms(animals) will go extinct gradually. This act affect the balance of the ecosystem and it can be referred to as the destruction of the habitat of living organisms

Therefore, the correct headings best complete the chart is :

X: Pollution

Y: Habitat Destruction

Single Displacement reaction  

In a displacement reaction, a more reactive element replaces a less reactive element from a compound.

Change in colour takes place with no precipitate forms.

Metals react with the salt solution of another metal.

Examples:

2KI + Cl2 → 2KCl + I2

CuSO4 + Zn → ZnSO4 + Cu

Double displacement reaction

In a double displacement reaction, two atoms or a group of atoms switch places to form new compounds.

Precipitate is formed.

Salt solutions of two different metals react with each other.

Examples:  

Na2SO4 + BaCl2 → BaSO4 + 2NaCl

2KBr + BaCl2 → 2KCl + BaBr2

Answer:

There would be an increase in temperature and corresponding increase in the volume of the balloon

Explanation:

Charles law is been here

Charles law  states that the volume of a given mass of gas  is directly proportional to the temperature in Kelvin, provided that the pressure on the gas is kept constant. Mathematically Charles law can be represented thus;

V∝ T

Where V is the volume of the gas and;

T is the temperature.

Relating Charles Law to the question

From Charles law postulation, there would be an increase in volume because of the increased temperature, since our pressure is same.

Answer:

[tex]\large \boxed{\text{21.6 L}}[/tex]

Explanation:

We must do the conversions

mass of C₆H₁₂O₆ ⟶ moles of C₆H₁₂O₆ ⟶ moles of CO₂ ⟶ volume of CO₂

We will need a chemical equation with masses and molar masses, so, let's gather all the information in one place.

Mᵣ:        180.16

         C₆H₁₂O₆ + 6O₂ ⟶ 6CO₂ + 6H₂O

m/g:      24.5

(a) Moles of C₆H₁₂O₆

[tex]\text{Moles of C$_{6}$H$_{12}$O}_{6} = \text{24.5 g C$_{6}$H$_{12}$O}_{6}\times \dfrac{\text{1 mol C$_{6}$H$_{12}$O}_{6}}{\text{180.16 g C$_{6}$H$_{12}$O}_{6}}\\\\= \text{0.1360 mol C$_{6}$H$_{12}$O}_{6}[/tex]

(b) Moles of CO₂

[tex]\text{Moles of CO}_{2} =\text{0.1360 mol C$_{6}$H$_{12}$O}_{6} \times \dfrac{\text{6 mol CO}_{2}}{\text{1 mol C$_{6}$H$_{12}$O}_{6}} = \text{0.8159 mol CO}_{2}[/tex]

(c) Volume of CO₂

We can use the Ideal Gas Law.

pV = nRT

Data:

p = 0.960 atm

n = 0.8159 mol

T = 37  °C

(i) Convert the temperature to kelvins

T = (37 + 273.15) K= 310.15 K

(ii) Calculate the volume

[tex]\begin{array}{rcl}pV &=& nRT\\\text{0.960 atm} \times V & = & \text{0.8159 mol} \times \text{0.082 06 L}\cdot\text{atm}\cdot\text{K}^{-1}\text{mol}^{-1} \times \text{310.15 K}\\0.960V & = & \text{20.77 L}\\V & = & \textbf{21.6 L} \\\end{array}\\\text{The volume of carbon dioxide is $\large \boxed{\textbf{21.6 L}}$}[/tex]
