In a synthesis reaction, two atoms of sodium (Na) combine with one molecule of chlorine gas (Cl2) to produce sodium chloride (NaCl). How many molecules of sodium chloride are produced?(1 point)
four
two
one
three
Answer: 2
Explanation: I DID DA TEST
A synthesis reaction is a chemical reaction in which two different atoms interact together to produce a different molecule or compound.
Sodium is an alkali metal with the atomic number 11. It has a +1 valence electron in its outermost shell.
Chlorine is a halogen family element with the atomic element 17. It requires an electron to complete its octet structure.
That is why the bonding reaction between them is called Electrovalent or Ionic bonding.
When 2 moles of Sodium (Na) combines with 1 mole of Chlorine (Cl), we have:
[tex]\mathbf{2 Na_{(s)} + Cl_2_{(g)} \ \to \ 2NaCl_{(s)} }[/tex]
Therefore, from the above reaction, we can conclude that there are two molecules of sodium produced when two atoms of sodium (Na) combine with one molecule of chlorine gas (Cl2).

What conditions might cause a
scientist to modify
or revise a
hypothesis
Answer:
Upon analysis of the results, a hypothesis can be rejected or modified, but it can never be proven to be correct 100 percent of the time. For example, relativity has been tested many times, so it is generally accepted as true, but there could be an instance, which has not been encountered, where it is not true.

When a metal such as copper is heated,it expands. Can anyone tell me what happens to the metal particles as the solid metal expands?
Answer:
The metal molecules inside start to vibrate faster, causing the solid to change to liquid if exposed to the intense temperature over a long period of time.
Explanation:
As my answer states, but for an explanation, lets say you are boiling an ice cube, it will start to turn into liquid water, that is because it has been exposed to that heat for a long period of time. The same will happen for the metal, if its exposed for long enough, it will turn into a liquid, then can be turned into a gas because the molecules are vibrating so quickly that they start to easily move apart.
Hope this helps, let me know if any more clarification is needed.

Give an example of derived unit.
Answer:
A derived unit is a unit that results from a mathematical combination of SI base units. We have already discussed volume and energy as two examples of derived units.
En la tienda compre una botella con agua la cual no venía etiquetada, ¿Que unidades de medición debe contener la etiqueta para saber la masa de la botella, su volumen y a qué temperatura debe mantenerse?
La unidad de medición para saber la masa de la botella es el gramo.
La unidad de medición para saber el volumen de la botella es el centímetro cúbico o el mililitro o el litro.
La unidad de medición para saber la temperatura de la botella es el grado Celsius.
Inicialmente, vamos a asumir que la botella de agua ha sido comprada en una zona donde las unidades del Sistema Internacional de Medidas es el Sistema Estándar de Pesas y Medidas. En este problema, se requiere conocer tres unidades para la Masa, el Volumen y la Temperatura, cuyas Unidades Fundamentales son las siguientes:
Masa - Kilogramo ([tex]kg[/tex])Volumen - Metro cúbico ([tex]m^{3}[/tex])Temperatura - Grado Celsius ([tex]^{\circ}\,C[/tex])Puesto que la adquisición de botellas de agua en almacenes se realiza en forma Minorista, tanto el Volumen como la Masa, Propiedades Extensivas de la Materia, deben basarse en Unidades Derivadas, es decir, Unidades relacionadas con Unidades Fundamentales mediante relación constante, mientras la Temperatura debe ser una Unidad Fundamental por ser una Propiedad Intensiva de la Materia. Las Unidades más usuales para la botella de agua son:
Masa - Gramo ([tex]g[/tex])Volumen - Centímetros Cúbicos ([tex]cm^{3}[/tex]) o Mililitros ([tex]mL[/tex]) o Litros (L)Temperatura - Grado Celsius ([tex]^{\circ}\,C[/tex])La unidad de medición para saber la masa de la botella es el gramo.
La unidad de medición para saber el volumen de la botella es el centímetro cúbico o el mililitro o el litro.
La unidad de medición para saber la temperatura de la botella es el grado Celsius.

The volume (V) of an enclosed mass of gas is 350kPa. The pressure of the endlosed gas is now decreased to 125kPa, at constant temperature. What will the new volume of the gas be, in terms of V (2)
Answer: V1/V2 = 0.357,
V2 = (V1/0.357) or 28.0*V2
Explanation: Use the combined gas law: P1V1/T1 = P2V2/T2 We want to find V1/2 (or V2/V1). Rearrange:
V1/V2 = (P2/P1)(T1/T2)
The units all cancel. Temerature is constant, so (T1/T2) = 1.
V1/V2 = (125/350)*(1)
V1/V2 = 0.357
