Answer : The incorrect option is, 53.6 hectometers (hm)

Explanation :

(1) The conversion used from kilometers to hectometers is:

1 km = 10 hm

Converting the given value, we get:

\Rightarrow 0.536km\times (\frac{10hm}{1km})=5.36hm

The value in hectometers is 5.36 hm

(2) The conversion used from kilometers to meters is:

1 km = 1000 m

Converting the given value, we get:

\Rightarrow 0.536km\times (\frac{1000m}{1km})=536m

The value in meters is 536 m

(3) The conversion used from kilometers to millimeters is:

1 km = 1000000 mm

Converting the given value, we get:

\Rightarrow 0.536km\times (\frac{1000000mm}{1km})=536000mm

The value in millimeters is 536000 mm

(4) The conversion used from kilometers to centimeters is:

1 km = 100000 cm

Converting the given value, we get:

\Rightarrow 0.536km\times (\frac{100000cm}{1km})=53600cm

The value in centimeters is 53600 cm

Hence, the incorrect answer is, 53.6 hectometers (hm)

A reaction in which a substance reacts with oxygen, emitting heat and forming oxygen-containing compounds is an example of a(n):
yaroslaw [1]

Answer: B) combustion reaction.

Explanation:

A) acid-base reaction: When an acid reacts with a base, to form metal salt and water, this type of reaction is Acid Base reaction.

Example: HCl+NaOH\rightarrow NaCl+H_2O

B) combustion reaction: When a hydrocarbon reacts with oxygen to produce carbon dioxide and water, this type of reaction is combustion reaction.

CH_4+2O_2\rightarrow CO_2+2H_2O

C) precipitation reaction: a reaction in which aqueous solution of two compounds on mixing react to form an insoluble compound which separate out as a solid are called precipitation reactions.

Na_2SO_4(aq)+BaCl_2(aq)\rightarrow BaSO_4(s)+NaCl(aq)

D) gas evolution reaction: a reaction in which one of the product is formed as a gas.

CaCO_3(s)\rightarrow CaO(s)+CO_2(g)

Use the formula: PV=nRT<br><br> If P=12, V=22.4, R=.0821 and T=100, then what would n=?
Lina20 [59]
PV=nRT \\ (12)(22.4)=n(.0821)(100) \\ 268.8=8.21n \\ 268.8/8.21=8.21n/8.21 \\ n=32.74
n ≈ 32.74

Describe the difference between a ball-and-stick model and a space-filling model of a compound.
Lisa [10]
A space-filling model shows the relative amount of space each atom takes up. In other words, a space-filling model can show relative sizes of atoms. However, unlike ball-and-stick or structural models, space-filling models do not show bond lengths clearly. Bonds are not really like sticks in a ball-and-stick model.
