Answer:

17.5% es la transmitancia de la solución problema

Explanation:

Basados en la ley de Beer que dice que:

La transmitancia de una solución es inversamente proporcional a su concentración.

Podemos hallar la transmitancia de una concentración problema sabiendo la concentración de una solución y su transmitancia:

Si una solución 0.0150M tiene una transmitancia de 35%

Y ahora la solución duplica su concentración, su transmitancia se disminuirá en la mitad, esto es:

35% / 2 =

Answer:

Answer:

2 moles NaClO3

Explanation:

2NaClO3 --> 2NaCl + 3O2

moles NaClO3 = 3 moles O2 x (2 moles NaClO3/3 moles O2) = 2 moles

conversion factor: 2 moles NaClO3 = 3 moles O2

In order to produce 3 moles of [tex]O_{2}[/tex], the chemical reaction needs to be balanced. the required number of moles of [tex]NaClO_{3}[/tex] are 2.

When the reactants undergo a chemical reaction, the number of moles on both the reactant and the product side must be balanced.

The chemical reaction of [tex]NaClO_{3}[/tex] is

2 [tex]NaClO_{3}[/tex]⇄2NaCl  + 3 [tex]O_{2}[/tex]

On the left side, 2 moles of [tex]NaClO_{3}[/tex] breaks into 2 moles of NaCL and 3 moles of [tex]O_{2}[/tex]. on the right side. Therefore, both side have an equal number of moles of each element.

Hence, two moles of [tex]NaClO_{3}[/tex] is required to produce 3 moles of [tex]O_{2}[/tex].

Answer:

The sun's gravity pulls on the earth, and the earth pulls back on the sun at the same time. This is why the center of the solar system is not the center of the sun. As one gravitational body gets bigger than the other, it circles closer to the center of the system (shown in red).

Explanation:

hope this helps...

The earth is known to be falling towards the sun as a result of intense gravity. The earth is known to have plenty of sideways momentum and due to this sideways momentum, the earth is often falling towards the sun and missing it.

The reason we are pulled to the center of the Earth and not into the much larger sun by gravity is that all objects with mass, like our Earth, do bend and curve the fabric of the universe referred to as spacetime.

At most, the gravity from the sun result in our planet moving in a curved, elliptical path. but, the planets are moving fast enough so that they are not pulled into the sun.

The sun has a more weaker gravity and as it loses mass, it causes the Earth to slowly move away from it.

Answer:

165.0 grams

Explanation:

The law of conservation of mass tells us that the mass of the reactants will be equal to the mass of the products. Therefore, if we begin with 165.0 grams of mass, that is how much there will be at the end in the products, even if it's in different forms.

Answer:

Solids, liquids and gases all expand when heat is added

Explanation:

When heat is added to a substance, the molecules and atoms vibrate faster. As atoms vibrate faster, the space between atoms increases. The motion and spacing of the particles determines the state of matter of the substance. ...

Answer:

True

Explanation:

Answer:

Cl2 + 2NaBr --> 2NaCl + Br2

Explanation:

This is a single displacement reaction where one side of the ionic compound switches with the other.

So, Cl2 + NaBr ---> NaCl + Br2

This isolates the Bromine and puts the Chlorine in it's place.

Then, balance out the equation like so and you should get

Cl2 + 2NaBr --> 2NaCl + Br2
