A substance is known to contain 2.00 g of carbon for every 5.33 g of oxygen. How many grams of carbon will be present in 55.0 g

nexus9112 [7]

First, set up a proportion:
You have 2.00 g Carbon and 7.33 g of the total substance (find it by adding 2.00g C + 5.33 g O)
You have an unknown g carbon with 55.0 g o total substance.

So:
$\frac{2.00}{7.33} = \frac{x}{55.0}$

Multiply 2.00 by 55.0 and divide the answer by 7.33
You'll get 20.63...

Dimas [21]

Answer:

Carbon dioxide: extinguishes CO2. By doing so, it removes oxygen from the fire, effectively suffocating it of oxygen. Class B fires

Foam: spray a type of foam that expands when it hits the air and blankets the fire. This prevents the vapors from rising off the liquid to feed the fire, thus starving it of fuel. Class A and B

Water: releases microscopic water molecules that fight the fire on a variety of levels. the level of oxygen in the air is decreased, which helps to suffocate the fire. Class: most all

also, your fire classes:

Class A: freely burning, combustible solid materials such as wood or paper

Class B: flammable liquid or gas

Class C: energized electrical fire (energized electrical source serves as the ignitor of a class A or B fire – if electrical source is removed, it is no longer a class C fire)

Class D: metallic fire (titanium, zirconium, magnesium, sodium)

Class K: cooking fires – animal or vegetable oils or fats
