Why does a raindrop accelerate as it falls to the earth?
allochka39001 [22]
Acceleration is the rate at which an object changes its speed. When a raindrop is falling down from the clouds due to gravity, the veloicty is pretty much fast, however air resistance comes in action and slows the droplet down... it gives it a constant speed until it hits the ground

Is a planar carbon "backbone" possible for propane? Explain.
tankabanditka [31]

Answer:

Cyclopropane has a planar carbon back bone while propane does not

Explanation:

We have to recognize that in straight chain saturated organic compounds, carbon atoms have a tetrahedral geometry. Each carbon atom is bonded to four other atoms.

However, carbon atoms in cyclic compounds are also sp3 hybridized with each carbon bonded to only four other atoms but the ring system is highly strained.

Cyclopropane is a necessarily planar molecule with a bond angle that is far less than the expected tetrahedral bond angle due to strain in the molecule. Hence, the carbon atoms may have have a "planar backbone".

Phosphine, an extremely poisonous and highly reactive gas, will react with oxygen to form tetraphosphorus decoxide and water, as
erica [24]

<u>Answer:</u> The amount of P_4O_{10} formed is 469.8 grams.

<u>Explanation:</u>

To calculate the number of moles, we use the equation:

\text{Number of moles}=\frac{\text{Given mass}}{\text{Molar mass}}     ......(1)

Given mass of phosphine = 225 g

Molar mass of phosphine = 34 g/mol

Putting values in equation 1, we get:

\text{Moles of phosphine}=\frac{225g}{34g/mol}=6.62mol

The given chemical reaction follows:

4PH_3(g)+8O_2(g)\rightarrow P_4O_{10}(s)+6H_2O(g)

Assuming that oxygen gas is present in excess, it is considered as an excess reagent.

Phosphine is considered as a limiting reagent because it limits the formation of product.

By Stoichiometry of the reaction:

4 moles of phosphine produces 1 mole of P_4O_{10}

So, 6.62 moles of phosphine will produce = \frac{1}{4}\times 6.62=1.655mol of P_4O_{10}

Now, calculating the mass of P_4O_{10} by using equation 1:

Molar mass of P_4O_{10} = 283.9 g/mol

Moles of P_4O_{10} = 1.655 moles

Putting values in equation 1, we get:

1.655mol=\frac{\text{Mass of }P_4O_{10}}{283.9g/mol}\\\\\text{Mass of }P_4O_{10}=(1.655mol\times 283.9g/mol)=469.8g

Hence, the amount of P_4O_{10} formed is 469.8 grams.
