Answer:

No because the sugar that went to it dissolved and the fruits are very blended in. It depends what smoothie it is because you can evaporate a strawberry smoothie and have only the strawberry mix instead of the water or milk.

For each of the following balanced chemical equations, calculate how many moles and how many grams of each product would be prod

anastassius [24]

Answer : The number of moles of $NH_4Cl$ and mass of $NH_4Cl$ is 0.50 mole and 27 grams respectively.

Solution : Given,

We are assuming that the reactant indicated in boldface is $NH_3$ . So,

Moles of $NH_3$ = 0.50 mole

Molar mass of $NH_4Cl$ = 53.5 g/mole

First we have to calculate the moles of $NH_4Cl$

The balanced chemical reaction is,

$NH_3(g)+HCl(g)\rightarrow NH_4Cl(s)$

From the reaction, we conclude that

As, 1 mole of $NH_3$ react to give 1 mole of $NH_4Cl$

So, 0.50 moles of $NH_3$ react to give 0.50 moles of $NH_4Cl$

The number of moles of $NH_4Cl$ is, 0.50 moles.

Now we have to calculate the mass of $NH_4Cl$

$\text{ Mass of }NH_4Cl=\text{ Moles of }NH_4Cl\times \text{ Molar mass of }NH_4Cl$

$\text{ Mass of }NH_4Cl=(0.50moles)\times (53.5g/mole)=26.75g\approx 27g$

The mass of $NH_4Cl$ is, 27 grams.

Eugenol is a molecule that contains the phenolic functional group. Which option properly identifies the phenol in eugenol

givi [52]

Answer:

Explanation:

Hello,

Among the options given on the attached document, since phenolic functional group is characterized by a benzene ring bonded with a hydroxyl group (C₆H₅OH) we can see that the first option correctly points out such description. Thus, answer is on the second attached picture. Other options are related with other sections found in eugenol that are not phenolic.

Best regards.

Consider a sample of 10.0 g of the gaseous hydrocarbon C2H6 to answer the following question: How many moles are present in this

Masja [62]

<u>Answer:</u> The moles of given hydrocarbon is 0.3 moles

<u>Explanation:</u>

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

$\text{Number of moles}=\frac{\text{Given mass}}{\text{Molar mass}}$

We are given:

Given mass of ethane = 10.0 g

Molar mass of ethane = $[(2\times 12)+(6\times 1)]=30g/mol$

We need to divide the given value by the molar mass.

Putting values in above equation, we get:

$\text{Moles of ethane}=\frac{10.0g}{30g/mol}=0.3mol$

In case of multiplication and division, the number of significant digits is taken from the value which has least precise significant digits. Here, the least precise number of significant digits are 1.

Hence, the moles of given hydrocarbon is 0.3 moles

The impact of fossil fuel combustion on the global carbon cycle

olga_2 [115]

When humans burn fossil fuels, the stored carbon is released into the atmosphere as carbon dioxide. The carbon is then free to cycle through the Earth and can upset the natural balance of the carbon available, changing the way that processes occur on Earth.
