Answer : The mass percentage of hydrogen in hexanal is, 12 %

Explanation: Given,

Molar mass of C = 12 g/mole

Molar mass of H = 1 g/mole

Molar mass of O = 16 g/mole

First we have to calculate the molar mass of hexanal.

Molar mass of hexanal (C_{6}H_{12}O) = 6(12)+12(1)+(16)=100g/mole

Now we have to calculate the mass of carbon.

As we now that there are 6 number of carbon atoms, 12 number of hydrogen atoms and 1 number of oxygen atoms.

The mass of hydrogen = 12\times 1=12g

Now we have to calculate the mass percentage of hydrogen in hexanal.

Formula used :

\%\text{ Mass percentage of hydrogen}=\frac{\text{Mass of hydrogen}}{\text{Mass of hexanal}}\times 100

Now put all the given values in this formula, we get:

\%\text{ Mass percentage of hydrogen}=\frac{12}{100}\times 100=12\%

Therefore, the mass percentage of hydrogen in hexanal is, 12 %

g A spontaneous process is one in which: A. releases a large amount of heat B. may happen (is possible) C. will rapidly approach
katrin2010 [14]

Answer:

A. releases a large amount of heat

Explanation:

A reaction is said to be spontaneous if it can proceed on its own without the addition of external energy. A spontaneous reaction is not determined by the length of time, because some spontaneous reactions are completed after a long period of time. They are exothermic in nature. An example is the conversion of graphite to carbon which takes a long period of time to complete. Spontaneous reactions are known to increase entropy in a system. Entropy is the rate of disorder in a system.

In the combustion of fire, energy is released to the surroundings as there is a decrease in energy. This is an example of a spontaneous reaction because it is an exothermic reaction, which causes an increase in entropy and a decrease in energy.

Utilizing dimensional analysis find the number of inches in a kilometer given that 1 inch equals 2.54 cm
hodyreva [135]
To solve this problem, separate it into chunks that you know. You know that there are 2.54 centimeters in 1 inch. You know that there are 100 centimeters in 1 meter. You know that there are 1000 meters in a kilometer. Therefore, we'll convert in this order: 1) from kilometers to meters, 2) from meters to centimeters, and 3) from centimeters to inches.
1) 1km × 1000m/1km
= 1000m
2) 1000m × 100cm/1m
= 100000cm
3) 100000cm × 1in/2.54cm
≈ 39370in
So, there are approximately 39370 inches in a kilometer.

A helium filled ballon had a volume of 8.50 L on the ground at 20.0 C and a pressure of 750.0 Torr. After the ballon was release
Marrrta [24]

Answer:

V_2=12.1L

Explanation:

Hello!

In this case, according to the given data of volume, pressure and temperature, it is possible to infer this problem can be solved via the combined gas law:

\frac{P_1V_1}{T_1} =\frac{P_2V_2}{T_2}

Thus, regarding the question, we evidence we need V2, but first we make sure the temperatures are in Kelvins:

T_1=20+273=293K\\\\T_2=-40+273=233K

Then, we obtain:

V_2=\frac{P_1V_1T_2}{T_1P_2}\\\\V_2=\frac{0.987atm*8.50L*233K}{293K*0.550atm}\\\\V_2=12.1L

Best regards!
