Answer: 0.96\times 10^{23} molecules

Explanation:

According to avogadro's law, 1 mole of every substance weighs equal to the molecular mass and contains avogadro's number 6.023\times 10^{23} of particles.

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

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

given mass of methyl alcohol = 5.0 g

Molar mass of methyl alcohol = 32.04 g/mol

Putting in the values we get:

\text{Number of moles}=\frac{5.0g}{32.04g/mol}=0.16moles

1 mole of methyl alcohol (CH_3OH) contains=6.022\times 10^{23}[/tex] molecules

Thus 0.16 moles of methyl alcohol (CH_3OH) contain=\frac{6.022\times 10^{23}}{1}\times 0.16=0.96\times 10^{23}

molecules

Thus there are 0.96\times 10^{23} molecules in 5.0 g of methyl alcohol.

What is the name of the thermodynamic barrier that must be overcome before products are formed in a spontaneous reaction?
Black_prince [1.1K]
Activation energy is a thermodynamic barrier that must be overcome before products are formed in a reaction. It is the minimum amount of energy needed for a reaction to occur. The energy can be in the form of kinetic or potential energy. This concept was introduced by Svante Arrhenius, which brought about the Arrhenius equation which is a formula used to determine rate of reactions.

A ball was massed in a dish. The total mass was 15.6 grams. Treball was placed in a
iVinArrow [24]

Answer:

14.57g

Explanation:

Given parameters:

Mass of dish + ball  = 15.6g

Initial volume of water in the cylinder  = 26.7mL  

Final volume of water in the cylinder  = 38.9mL

Mass of dish = ?

Unknown

Mass of the ball = ?

Solution;

 Since the mass of ball and dish is 15.6g,

 Mass of the ball  =Mass of ball + dish  - mass of the dish

 Insert the parameters and solve;

 Mass of the ball  = 15.6g  - 1.03g  = 14.57g

<u><em>I believe the answer you are looking for is position 4 </em></u>, because the northern face of the hemisphere is facing away from the sun not getting

to much heat nor daylight therefore its cold making it winter fully in option 4.

Just a tip option 3 looks like its facing back but half of it is still shown to the sun.
