A chemical bond is a strong attraction between two or more atoms. Can you identify the properties of different types of chemical

bonds?1. A(n) ___________ bond forms when one atom gives up one or more electrons to another atom.2. Atoms or molecules with a net electric charge due to the loss or gain of one or more electrons are ____________.3. A(n) __________bond involves the sharing of electron pairs between atoms, also known as amolecular bond.4. When one pair of electrons is shared between two atoms, a ___________bond is formed.5. When two pairs of electrons are shared between two atoms, a _____________bond is formed.6. A _____________bond is a type of chemical bond where a pair of electrons is unequally shared betweentwo atoms. As a result, one end of the molecule has a slightly negative charge and the other a slightlypositive charge.7. Atoms involved in a ___________bond equally share electrons; there is no charge separation to the molecule.8. A weak bond called a____________bond results from an attraction between a slightly positive regionin a molecule and a slightly negative region in the same or a different molecule.a. Hydrogen b. Double c. Polar d. Covalent e.Ions f. Single g. Nonpolar

Chemical equation below demonstrate that?<br> NEED HELP ASAP

(a) Matter cannot be created and destroyed by a chemical reaction.

Explanation:

(a) Matter cannot be created and destroyed by a chemical reaction. (correct)

The number and type of atoms entering the chemical reaction are the same with the number and type of atoms leaving the chemical reaction.

(b) The reactants are the same substance as the products. (wrong)

You may see in the reaction that we have as reactants zinc and hydrochloric acid which react to form the products, zinc chloride and hydrogen.

(c) The number of molecules in the reactants are equal to the number of molecules in the products. (wrong)

As reactants we have 2 hydrochloric acid (HCl) molecules and as products 1  hydrogen (H₂) molecule. Zn is a metal and ZnCl is a salt.

(d) The atoms on the reactants side are changed into different atoms on the products side. (wrong)

The number and type of atoms entering the chemical reaction are the same with the number and type of atoms leaving the chemical reaction.

How many bonding electrons are drawn in NH4+1?
Reil [10]

Answer:

What is the total number of valence electrons in the Lewis structure of nh4+?

Total valence electrons pairs

Total electron pairs are determined by dividing the number total valence electrons by two. For, NH4+, Total pairs of electrons are 4.

HURRY!!!! TIMED!!! WILL GIVE BRAINLIST!!!

Explanation:

(a) write a balanced equation for the reaction

CaCO3 + HCl --> CaCl2 + H2O + CO2

The balanced equation is given as;

CaCO3 + 2HCl → CaCl2 + H2O + CO2  

(b) when the reaction was complete, 800 mL of carbon dioxide gas was collected. How many moles of calcium carbonate were used in the creation?

From the balanced reaction;

1 mol of CaCO3 reacts to produce 1 mol of CO2

1 mol of CO2 = 22.4 L of CO2

This means;

1 mol of CaCO3 reacts to produce 22.4L  of CO2

x mol would produce 800ml (0.8 L) of CO2

1 = 22.4

x = 0.8

x = 0.8 * 1 / 22.4 = 0.0357 mol

(c) How many grams of CaCO3 were used?

Mass = Number of moles * Molar mass

Molar mass of CaCO3 = 100.0869 g/mol

Mass = 0.0357 mol * 100.0869 g/mol = 3.57 g

(d) If there was another contaminant in the sample that was not un reactive, would this have caused the percent yield of carbon dioxide to be higher, lower, or the same, explain your answer.

The same

An un reactive contaminant in the sample is most likely a catalyst. Catalysts only affect the rate of reaction. They do not affect yields of products.
