If you start with 3 moles of sodium and 3 moles of chlorine to produce sodium chloride, what is the limiting reagent?(You will need to balance
the equation first.)
Na + Cl2 -> NaCl A. They are equal B. Na C. Cl2 D. NaCl

If You Start With 3 Moles Of Sodium And 3 Moles Of Chlorine To Produce Sodium Chloride, What Is The Limiting

Answers

Answer 1

Answer:

B. Na

Explanation:

Once balanced you get 2Na + Cl₂ ⇒ 2NaCl. Sodium is the limiting reagent because it would produce the smallest amount of the product (NaCl)–while chlorine is the excess reagent. Based off of the Na in the balanced equation, it would produce 3 moles of NaCl, and for Cl₂ it would produce an excess of 6 moles of NaCl. [It'd be wise to utilize stoichiometric factors to get a good grasp of this]

Whic statements explain why rocks weather at different rates? Check all that apply

Answers

Explanation:

Weathering occurs one of three ways: through physical processes such as freezing and thawing, because of live organisms whose roots break rocks or through chemical processes that occur when carbon dioxide in the soil and air and mixes with water and specific minerals in rocks to form a weak acid that reduces rocks into silt, soil and sediment.

Chemical weathering typically increases as temperatures rise and rain falls, which means rocks in hot and wet climates experience faster rates of chemical weathering than do rocks in cold, dry climates.

Explanation:

Answer: Hope this helps:)

The Law of Conservation of Mass dates from Antoine Lavoisier's 1789 discovery that mass is neither created nor destroyed in chemical reactions. In other words, the mass of any one element at the beginning of a reaction will equal the mass of that element at the end of the reaction. The law of conservation of matter states that in any given system that is closed to the transfer of matter, the amount of matter in the system stays constant. The law of conservation of matter says that in chemical reactions, the total mass of the products must equal the total mass of the reactants. French chemist A. Lavoisier laid the foundation to the scientific investigation of matter by describing that substances react by following certain laws. These laws are called the laws of chemical combination. Matter says that the amount of matter stays the same, even when matter changes form. Sometimes it may seem that matter disappears during a science experiment, but this law tells us that matter cannot magically appear or disappear, it simply changes from one form to another. Matter can change form through physical and chemical changes, but through any of these changes, the matter is conserved. The same amount of matter exists before and after the change—none is created or destroyed. This concept is called the Law of Conservation of Mass.

Order the following elements from Highest to Lowest Electronegativity.

Answers

Answer:

O, Ca, Zn, Br

Sc, K, Br,

Explanation:

The correct order of the chemical elements from highest to lowest electronegativity is: C. Br, Zn, Sc, Ca, K.

Electronegativity refers to a measure of the ability of an atom of a chemical element to attract any shared pair of electrons.

Generally, the electronegativity of a chemical element typically increases across the period from left to right.

In Chemistry, the electronegativity of some of the chemical element are:

Bromine (Br) = 2.96Calcium (Ca) = 1.0Zinc (Zn) = 1.65Potassium (k) = 0.82Scandium (Sc) = 1.36

Hence, the order of the chemical elements from highest to lowest electronegativity is:

1. Bromine (Br) = 2.96

2. Zinc (Zn) = 1.65

3. Scandium (Sc) = 1.36

4. Calcium (Ca) = 1.0

5. Potassium (k) = 0.82

A student heats a 2.5 g sample of calcium carbonate in a test tube. What mass of calcium oxide remains in the test tube when the reaction is complete?
CaCO3(s) = CaO(s) + CO2(g)

Select one:
a. 1.4 g CaO
b. 2.1 g CaO
c. 2.5 g CaO
d. 1.0 g CaO

Answers

Answer:

1.4 g CaO

Explanation:

Given data:

Mass of calcium carbonate = 2.5 g

Mass of Cao remain in tube = ?

Solution:

Chemical equation:

CaCO₃    →     CaO + CO₂

Number of moles of CaO:

Number of moles = mass/molar mass

Number of moles = 2.5 g/ 100 g/mol

Number of moles = 0.025 mol

now we will compare the moles of CaO with CaCO₃.

                    CaCO₃        :          CaO

                        1              :             1

                    0.025         :         0.025

Mass of CaO:

Mass = number of moles × molar mass

Mass = 0.025 mol × 56 g/mol

Mass = 1.4 g

Answer:

1.4g CaO

Wood is one of the most common and useful natural materials. It is the main tissue that supports and conducts nutrients in trees and other plants. Wood comes in a variety of colours & grain patterns and is produced by numerous botanical species, comprising both gymnosperms & angiosperms.

Its wood's tensile strength is reduced. Another risk factor for the strength of the wood is the loading time. The rigidity of wood is affected by temperature. Unfavourable weather and unexpected temperatures will have an impact on the wood's strength. Among its attributes are mechanical, chemical, and physical qualities.

Aluminum nitrate reacts with sodium hydroxide to form a precipitate of aluminum hydroxide. What mass of aluminum hydroxide will precipitate when 35.5 mL of 0.145 mol/L aqueous aluminum nitrate is mixed with 44.2 mL of 0.215 mol/L aqueous sodium hydroxide?

Answers

Answer:

The mass of aluminum hydroxide that will precipitate when 35.5 mL of 0.145 mol/L aqueous aluminum nitrate is mixed with 44.2 mL of 0.215 mol/L aqueous sodium hydroxide is approximately 0.247 grams

Explanation:

The given parameters are;

The volume of 0.145 mol/L aqueous aluminum nitrate in the reaction = 35.5 mL

The volume of 0.215 mol/L aqueous sodium hydroxide in the reaction = 44.2 mL

The balanced chemical equation for the reaction is given as follows;

Al(NO₃)₃ (aq) + 3NaOH (aq) → Al(OH)₃ (s) + 3NaNO₃ (aq)

Therefore;

1 mole of Al(NO₃)₃, reacts with 3 moles of NaOH to form 1 mole Al(OH)₃, and 3 moles of NaNO₃

The number of moles of aqueous aluminum nitrate in the reaction = 35.5/1000 L × 0.145 mol/L = 0.0051475 moles

The number of moles of aqueous sodium hydroxide in the reaction = 44.2/1000 L × 0.215 mol/L = 0.009503 moles

Therefore, 0.009503 moles NaOH will react with 0.009503/3 moles Al(NO₃)₃ to form 0.009503/3 moles of aluminum hydroxide precipitate

The molar mass of aluminum hydroxide = 78 g/mol

Therefore, 0.009503/3 moles of aluminum hydroxide weighs 78 × 0.009503/3 = 0.247078 grams

The mass of aluminum hydroxide that will precipitate out ≈ 0.247 grams.

2. How many liters of propane gas (C3H8) will undergo complete combustion with 34.0 L of oxygen gas? ___ C3H8 (g) + ___ O2 (g → ___ CO2 (g + ___ H2O(g

Answers

Answer:

6.8 liters of propane gas will undergo a complete combustion with 34.0 L of oxygen gas.

Explanation:

Given;

combustion reaction of propane and oxygen;

C₃H₈ + O₂(g)  → CO₂(g)     + H₂O(g)

Balance the chemical reaction as follows;

C₃H₈ + 5O₂(g)  → 3CO₂(g)   +   4H₂O(g)

From the balanced equation;

1 mole of C₃H₈ ---------------- 5 moles of 5O₂(g)

x Liters of C₃H₈ ----------------- 34.0 Liters of O₂(g)

x = 34 liters / 5

x = 6.8 liters

Therefore, 6.8 liters of propane gas will undergo a complete combustion with 34.0 L of oxygen gas.
