Elena L [17]

════════ ∘◦❁◦∘ ════════

<h3>Answer = 2</h3>

════════════════════

<h3>Known</h3>

Mass = 32grams

Name of atom = Methane (CH4)

Molar mass C = 12

Molar mass H = 1

════════════════════

<h3>Question</h3>

molecules (mol?)

════════════════════

<h3>Way to do</h3>

mass = mol × molar mass

32g = mol × (CH4)

33g = mol × (12 + (4×1))

32g = mol × 16

mol = 32 : 16

mol = 2

════════════════════

#Ey tell me if its mol or total particles

What do scientists do to easily share measurements data they can understand
Stells [14]

These days, scientists all over the world use a standard system of measurements.  It's the SI or metric system.

What about scientists in the United States, Liberia, and Burma ?  These three countries are the only ones in the world that haven't adopted the metric system.  What do THEY do ?Easy.  When scientists in those countries are off work, they use the inches, yards, feet, quarts, miles and gallons that everybody around them is using.  But when they go to work, they use the same metric system that everyone else in the world is using.

Which is an example of a base?a(lemon juice b(baking soda c(an insolator d( water
bija089 [108]

Answer:

b) Baking soda

Explanation:

Baking soda is sodium hydrogen carbonate, NaHCO₃.

It reacts with water according to the equation

NaHCO₃ + H₂O ⇌ H₂CO₃ + NaOH

Thus, baking soda is a base because it increases the concentration of hydroxide ions in water.

<em>Water</em> is <em>neutral</em>.

<em>Lemon juice</em> is an <em>acid</em> because it contains citric acid.

An <em>insulator </em>is a substance that does not conduct electricity. Insulators are <em>neither acidic nor basic</em>.
