DIMENSIONAL ANALYSIS PLSSSSconvert 19 inches to feet(show work)

Chemistry

19 in = 1.6 ft

You know that

12 in = 1 ft

If you divide both sides by 12 in, you get the <em>conversion factor</em>: 1 = 1 ft/12 in.

If you divide both sides by 1 ft, you get the <em>conversion factor</em>: 12 in/1 ft = 1.

Both are conversion factors because they <em>both equal one</em> and <em>multiplying a measurement by one does not change its value</em>.

You choose the conversion that gives you the correct dimensions for your answer. It must have the correct dimensions <em>on top</em> (in the numerator),

Thus, to convert 19 in to ft, you use the conversion factor with “ft” on the top.

∴ Length = 19 in × (1 ft/12 in) = 1.6 ft

What measurement is the radius of the atom?

Oduvanchick [21]

Answer:

The atomic radius (r) of an atom can be defined as one half the distance (d) between two nuclei in a diatomic molecule. Atomic radii have been measured for elements. The units for atomic radii are picometers, equal to 10−12 meters

Write the formula of the conjugate acid of HCO₂⁻.

Alex

Taking into account the Brønsted-Lowry acid-base theory, the conjugate acid of HCO₂⁻ is H₂CO₂.

<h3>Brønsted-Lowry acid-base </h3>

The Brønsted-Lowry acid-base theory (or the Brønsted-Lowry theory) identifies acids and bases based on whether the species accepts or donates protons or H⁺.

According to this theory, acids are proton donors while bases are proton acceptors. That is, an acid is a species that donates an H⁺ proton while a base is a chemical species that accepts an H⁺ proton from the acid.

So, reactions between acids and bases are H⁺ proton transfer reactions.

<h3>Conjugate base and conjugate acid</h3>

Then, a conjugate base is an ion or molecule resulting from the acid that loses the proton, while a conjugate acid is an ion or molecule resulting from the base that gains the proton:

acid + base ⇄ conjugate base + conjugate acid

<h3>Conjugate acid of HCO₂⁻</h3>

Like a conjugate acid is an ion or molecule resulting from the base that gains the proton, the conjugate acid of HCO₂⁻ is H₂CO₂.

Convert 1.50μm2 to square meters

IrinaVladis [17]

1 micro meter = $10^{-6} meters$
1 μm ^2 = 1 μm*1μm = $10^{-6} *10^{-6} = 10^{-12}$ meters

1.5 μm^2 = 1.5 * $10^{-12}$ meters

μm^2 is a unit for surface. First you want to convert μm to meters which is unit for length and if you multiply units for length you get unit for surface.

What type of reaction does each of the following equations represent?

vekshin1

Answer:

Option C. Decomposition

Explanation:

To know which option is correct, it is important we know what is a single displacement reaction, double displacement reaction and decomposition reaction.

A Single displacement reaction can be defined as a reaction in which a single element is replaced by another element in a compound.

A double displacement reaction is a reaction involving the exchange of ions of two parts of ionic compounds to form two different compounds.

A decomposition reaction is a reaction in which a compound splits into two or more simpler compound or element.

Bearing the above definitions in mind and considering the question given above, we can conclude that the reaction given in the question above is a decomposition reaction since the compound (NH₄OH) splits into two different compound (NH₃ and H₂O)
