Answer: Option (a) is the correct answer.

Explanation:

Pressure is defined as the force applied on per unit area.

Mathematically,          Pressure = \frac{Force}{Area}

When we squeeze a balloon then it means we are applying pressure on it. Also, we are decreasing the area of balloon by applying more amount of force on it.

As area is inversely proportional to pressure. So, a decrease in area will lead to an increase in pressure.

Hence, we are increasing the pressure on the balloon by squeezing it.

Thus, we can conclude that if a balloon is squeezed, then pressure of the gas inside the balloon increases.

Ethanol (C2H5OH) is produced from the fermentation of sucrose in the presence of enzymes.
Klio2033 [76]

Explanation:

to calculate theoratical yield...first we must calculate how much Sucrose moles we have..in order to to do so...we must calculate molar mass of sucrose.

molar mass of sucrose is 342.3 g/mol.

now we can calculate how many sucrose moles we have by dividing the mass with molar mass of sucrose

735g/(342.3g/mol)=2.147mol

theoratically...according to stoichiometry..every 1 mole of sucrose yields 4 moles of ethanol...so...

2.147mole yield 2.147*4mol=8.588mol

now we must calculate weight of that much ethanol..molar mass of ethanol is 46.07 g/mol...

so we can multiple moles by molar mass to obtain the weight 8.588mol*46.07g/mol=395.649g

but we only obtained 310.5g...so percentage we have is

\frac{310.5}{395.649}  \times 100

78.47%

if there is trouble with molar mases I used....use what you calculated...

If my explanation is good enough...please mark it as brainliest.thanks

USPshnik [31]

Answer:

The answer to your question is: Includes sulfur and gain two electrons

Explanation:

Includes Chlorine  This option is wrong, Chlorine belongs to group VII.

Includes Sulfur  This option is true, Group VI includes Oxygen, Sulfur, Selenium, Tellurium.

Gain 2 electrons . This option is true, Elements in group VI have six valence electrons so they gain to electrons to become estable.

Tend to form +2 ions  This option is wrong, this elements form -2 ions

Have 5 valence electrons This option is wrong, this elements have 6 valence electrons.

Maple has a sample of graphite, which is made up of carbon atoms. She has 1.810 x 1024 atoms of carbon. What is the mass of this
Lera25 [3.4K]

Answer:

  about 36.10 g

Explanation:

The proportion of interest is ...

  mass/atoms = x/(1.810·10^24) = (12.0107 g)/(6.02214076·10^23)

Multiplying by 1.810·10^24, we find the mass of the sample to be ...

  x = 36.0991 g

The mass of the sample is about 36.10 grams (to 4 s.f.).
