Hydrogen gas can combine with oxygen gas under certain conditions to form water. Which name is a general term for water in this
antoniya [11.8K]

Product

Explanation:

Water in this reaction is called the product of the reaction.

The product is the new kind of matter formed as a result of a chemical change. They are produced from the combination of reactants.

                          2H₂  +   O₂        →        2H₂O

                           Reactants              Products

A chemical reaction involves the combination of chemical species to form a product. The type of reaction above is a called synthesis reaction.

D = m / V


It even gives you the density of gold in the problem. Major hint. Once you know the volume (using V = m / D) then you can calculate the height (thickness) from the equation...


V = L x W x H

Volume = Length x Width x Height


start by converting 200.0 mg into grams

1000 mg = 1 g

200. mg x (1 g / 10^3 mg) = 0.200 g


V = m / D

V = 0.200 g / (19.32 g/cm^3)

V = 0.01035 cm^3


Convert 2.4 ft and 1 ft to cm

2.4 ft x (12 in / 1 ft) x (2.54 cm / 1 in) = 73.15 cm

1 ft = 30.48 cm


Compute the height (thickness)

V = LxWxH

H = V / LW = 0.01035 cm^3 / 73.15 cm / 30.48 cm

H = 4.64 x 10^-6 cm


Convert to nanometers

4.64 x 10^-6 cm x (1 m / 100 cm) x (10^9 nm / 1 m) = 46.4 nm


Knowing the atomic radius of gold, I might have asked my students for the minimum number of gold atoms in this thickness of gold. This would assume that the gold atoms are all in a row. This would give the minimum number of gold atoms.


Atomic radius gold = 174 pm

Diameter = 348 pm


46.4 nm x (1 m / 10^9 nm) x (10^12 pm / 1 m) x (1 Au atom / 248 pm) = 133 atoms of gold

A compound accepts electrons from another substance to form a covalent bond. Which term best describes this compound’s behavior?
Cloud [144]

A compound accepts electrons from another substance to form a covalent bond. The compound acts as a Lewis base.

<h3>What are the most common acid-base theories?</h3>
  • Arrhenius: acids release H⁺ and bases release OH⁻.
  • Bronsted-Lowry: acids donate H⁺ and bases accept H⁺.
  • Lewis: acids accept electrons and bases donate electrons.

A compound accepts electrons from another substance to form a covalent bond. Which term best describes this compound’s behavior?

  • Lewis acid. YES.
  • Arrhenius base. NO, because OH⁻ is not involved.
  • Bronsted-Lowry acid. NO, because H⁺ is not involved.
  • Bronsted-Lowry base. NO, because H⁺ is not involved.
