1.2 mm

a) Calculate the <em>volume</em> of the block

<em>V </em>= 50 g x (1 cm^3/8.64 g) = 5.79 cm^3

b) Calculate the <em>height</em> of the block

The formula for the volume (V) of a block is

<em>V = lwh </em>

where

<em>l</em> = the length of the block

<em>w</em> = the width of the block

<em>h</em> = the height of the block

We can solve this formula for the height.

<em>h = V</em>/(<em>lw</em>)

∴ <em>h</em> = 5.79 cm^3/(10 cm x 5 cm) = 0.12 cm = 1.2 mm

Please help balance <br> _Ch7H16+_O2=_CO2+_H2O
iren2701 [21]

Answer:

C7H16 + 11 O2 → 7 CO2 + 8 H2O

This is an oxidation-reduction (redox) reaction:

7 C-16/7 - 44 e- → 7 CIV (oxidation)

22 O0 + 44 e- → 22 O-II (reduction)

C7H16 is a reducing agent, O2 is an oxidizing agent.

Reactants:

C7H16

-. Is Electricity naturally produced in our environment.
andre [41]
Electricity is not a naturally occurring energy phenomenon like oil from the ground, but it must be created and refined at electrical power plants using other energy sources. The natural resources that create electric energy are usually non-renewable, with some exceptions.
