Si la masa de una muestra de un compuesto Y es de 196 gramos y contiene 2 mol, la masa molar de Y es

Answers

Answer 1

Answer:

98 g/mol

Explanation:

La masa molar de un compuesto es la cantidad de materia (medida como masa) que hay en 1 mol de dicho compuesto. Por lo tanto, puede calcularse como sigue:

masa molar = masa/número moles

Tenemos los siguientes datos del compuesto Y:

masa Y = 196 g

número de moles de Y = 2 mol

Entonces, podemos calcular la masa molar de Y de la siguiente manera:

masa molar Y = (masa Y)/(número de moles de Y) = 196 g/2 mol = 98 g/mol

Cuando se trata Ca3P2 con agua, los productos son Ca(OH)2 y PH3. Calcular el peso máximo obtenido al reaccionar 2 g de Ca3P2 con 1 g de H2O.

Answers

Answer:

0.629 gramos de PH3 es la máxima de cantidad que puede ser producida.

Explanation:

¡Hola!

En este caso, dado que tenemos la siguiente reacción química, la cual se puede balancear directamente:

[tex]Ca_3P_2+6H_2O\rightarrow 3Ca(OH)_2+2PH_3[/tex]

Podemos calcular la masa máxima de cualquier producto, digamos PH3, al comparar la masa de este, que 2 g the Ca3P2 y 1 g de H2O producen por separado y de acuerdo a la estequiometría:

[tex]2gCa_3P_2 *\frac{1molCa_3P_2 }{182.18gCa_3P_2 }*\frac{2molPH_3}{1molCa_3P_2 } *\frac{34gPH_3}{1molPH_3 } =0.747gPH_3\\\\1gH_2O *\frac{1molH_2O }{18.02gH_2O}*\frac{2molPH_3}{6molH_2O} *\frac{34gPH_3}{1molPH_3 } =0.629gPH_3[/tex]

De este modo, infermos que solamente 0.629 gramos the PH3 pueden ser obtenidos al ser el agua el reactivo límite.

A greater force is required to move an object with a larger mass than one with a smaller
mass.

Answers

Answer:

Explanation:

what do u need to know

The greater the force that is applied to an object of a given mass, the more the object will accelerate. The greater the mass of an object, the less it will accelerate when a given force is applied. For example, doubling the mass of an object results in only half as much acceleration for the same amount of force. Hope this helps!

If 4.04g of h2 gas react with oxygen gas to create 36.36g of water, how many grams of oxygen reacted?

Answers

Answer:

gO₂ = 32.32 g

Explanation:

In this case, let's write the general equation:

2H₂ + O₂ -------> 2H₂O

In this case, we can use the 1° law, which is mass conservation. If the product has 36.36 g of water, then in the reactants we should have the same 36.36 g.

According to this, we already have 4.04 of hydrogen, then the remaining to reach the 36.36 g would be:

gO₂ = 36.36 - 4.04

gO₂ = 32.32 g

Hope this helps

Sample A has a mass of 40g and a volume of 10cm^3. Sample B has a volume of 15cm^3 and a mass of 45g. Which sample has a greater density? Show your work.​

Answers

The Answer Is Sample A

Density -

[tex]density = \frac{mass}{volume} [/tex]

Input The Formula For Both Equations To Find Density.

Sample A -

[tex]d = \frac{40}{10} [/tex]

[tex]d = 4[/tex]

Sample B -

[tex]d = \frac{45}{15} [/tex]

[tex]d = 3[/tex]

Easy points: Is this a good paragraph for my biology class??The question was why is it important for soil to contain nitrogen, phosphorus, magnesium, and potassium.Soil is one of the main sources of nutrients needed by plants in order to grow. Nitrogen is used by plants for leaf growth and green color. Without nitrogen in the soil, the plant wouldnt grow tall and produce enough food.Phosphorus is used by plants to help form new roots, make seeds, fruit and flowers.This is crucial because crops take up phosphorus only from the soil solution.Potassium helps plants form strong stems and fast growth. It also increases disease resistance.It triggers activation of enzymes and is essential for production of ATP. Magnesium is the central core of the chlorophyll molecule in the plants tissue. If Mg is deficient, the shortage of chlorophyll results in poor and stunted growth. Approximate, in square meters, the area of a circle with radius = 58.2 m.
