Answer:
33.95 grams of NaN3
Explanation:
Number of moles of NaN3 = mass (m)/MW = m/65 mole
I mole of NaN3 requires 22.4L air bag
m/65 mole of NaN3 required 11.7L
22.4m/65 = 11.7
22.4m = 65×11.7
22.4m = 760.5
m = 760.5/22.4 = 33.95grams of NaN3
Answer:
Its B I just took the test and got a 100%
Explanation:
Answer:
El volumen final del sistema es 1.2L
Explanation:
La ley de Charles establece que el incremento de la temperatura de un gas produce un incremento en el volumen directamente proporcional cuando la presión permanece constante. La ecuación es:
V₁/T₁ = V₂/T₂
<em>Donde V es volumen y T temperatura absoluta de un gas en 1, el estado inicial y 2, su estado final.</em>
<em />
Reemplazando:
V₁ = 1.3L
T₁ = 50°C + 273.15K = 323.15K
V₂ = Incógnita
T₂ = 300K
1.3L/323.15K = V₂/300K
1.2L = V₂
<h3>El volumen final del sistema es 1.2L</h3>
A substance is an element if it consists of a single type of atom. A substance is a compound if it is made up of more than one element.
<h3>Elements and compounds</h3>
In chemistry, an element is defined as all pure substances consisting of the same atom. For example, magnesium and potassium metal are all elements because they consist of magnesium and potassium atoms only.
On the other hand, compounds are defined as substances consisting of 2 or more atoms of different elements. For example, sodium chloride consists of atoms of sodium and chlorine. Hence, it is considered to be a compound.

It's something to do with the weathering process.
Eg. At night it's really cold, and in the day it's really hot.
Because the temperature keeps changing dramatically day in and day out,
the sand dunes start to be sort of hacked or re-shaped, or even formed.
