A) The number of butterflies will drop.
B) The number of larvae will not change.

Answer: Option A

Explanation: The number of butterflies will drop, as the larvae of swallowtail butterfly eat this plant. The plant will decrease in huge amount.

One because of habitat loss as the the wetlands in Georgia have been cleared due to agriculture and construction.

Secondly, the endangered plant is being eaten by the larvae so there will be a decrease in the population of the plant.

The number of butterflies will drop because the plant population will decrease.

What force opposes gravity and keeps objects from falling to the center of<br> the earth?
stiv31 [10]

La fuerza de la gravedad depende de la masa (el peso) de cada objeto. La fuerza con que se atraen dos objetos es proporcional a su masa y disminuye rápidamente en el momento en que los separamos. De hecho, nosotros también atraemos objetos con ‘nuestra’ fuerza gravitatoria, pero pesamos tan poco que no podemos percibirlo. En cambio, el Sol es tan grande que es capaz de mantenernos girando a su alrededor a pesar de estar muy lejos. La Luna también ejerce su propia fuerza gravitatoria, pero, como es más pequeña y ligera que la Tierra, si nos pesásemos sobre su superficie veríamos que pesamos unas seis veces menos que en la Tierra.

Podríamos preguntarnos por qué la Luna no cae sobre la Tierra al igual que una manzana cae del árbol. La razón es que nuestro satélite nunca está quieto. Se mueve constantemente a nuestro alrededor. Sin la fuerza de atracción terrestre, se alejaría flotando en el espacio. Gracias a esta combinación de velocidad y distancia de nuestro planeta, la Luna siempre está en equilibrio, ni cae ni se aleja. Si se moviera más rápido, se alejaría, si se moviera con más lentitud, ¡caería!

Hemos dicho que la fuerza de la gravedad también depende de la distancia. Si nos alejásemos lo suficiente de la Tierra, escaparíamos a su fuerza de atracción. Y eso es lo que tratamos de hacer con las naves espaciales. Necesitamos superar la llamada ‘velocidad de escape’, que es aproximadamente 11,2 km/s (a esa velocidad, podríamos viajar de Londres a Nueva York ¡en tan solo 10 minutos!). Cuando un cohete alcanza esa velocidad, ya es libre para viajar por el sistema solar.

Dentro de una nave en órbita, no sentimos la fuerza de la gravedad terrestre. Los objetos no caen, sino que flotan, así que si saltas, no regresas al suelo. Es lo que les ocurre a los astronautas cuando están a bordo de una estación espacial que orbita alrededor de la Tierra.

Answer: Moles of hydrogen required are 4.57 moles to make 146.6 grams of methane, CH_{4}.

Explanation:

Given: Mass of methane = 146.6 g

As moles is the mass of a substance divided by its molar mass. So, moles of methane (molar mass = 16.04 g/mol) are calculated as follows.

Moles = \frac{mass}{molar mass}\\= \frac{146.6 g}{16.04 g/mol}\\= 9.14 mol

The given reaction equation is as follows.

C + 2H_{2} \rightarrow CH_{4}

This shows that 2 moles of hydrogen gives 1 mole of methane. Hence, moles of hydrogen required to form 9.14 moles of methane is as follows.

Moles of H_{2} = \frac{9.14}{2}\\= 4.57 mol

Thus, we can conclude that moles of hydrogen required are 4.57 moles to make 146.6 grams of methane, CH_{4}.
