The boiling point of ethanol is 78.3 degrees Celsius. The boiling point of

ethanol on the Kelvin scale is approximately... *

Answers

Answer 1

Answer:

K = 351.3

Explanation:

The relationship between the Celsius scale and kelvin scale is;

K = 273 + C

Since the Celsius temperature = 78.3

The kelvin temperature is given as;

K = 273  + 78.3

K = 351.3

Answers

Answer:

It's False

Explanation:

In a chemical reaction, reactants that are not used up when the reaction is finished are called excess reagents. The reagent that is completely used up or reacted is called the limiting reagent, because its quantity limits the amount of products formed.

3. A sample of neon gas has a volume of 1.2 L at 28.5°C. What will the volume be at 125°C it the
pressure remains constant?

Answers

Answer:

1.58L

Explanation:

Given parameters:

Initial volume  = 1.2L

Initial temperature  = 28.5°C  = 28.5 + 273  = 301.5K

Final temperature  = 125°C  = 125 + 273  = 398K

Unknown:

New volume  = ?

Solution:

Volume and temperature relationship is resolved using the Charles's law.

The law states that "the volume of a fixed mass of a gas varies directly as its absolute temperature if the the pressure is constant".

So;

       [tex]\frac{V1}{T1}[/tex]    = [tex]\frac{V2}{T2}[/tex]  

V1 is the initial volume

T1 is the initial temperature

V2 is the new volume

T2 is the new temperature

             [tex]\frac{1.2}{301.5}[/tex]    = [tex]\frac{V2}{398}[/tex]    

              301.5V2  = 477.6

                       V2  = 1.58L

Answer:Through "gene escape" they can pass on to other members of the same species and perhaps other species. Genes introduced in GMOs are no exception, and interactions might occur at gene, cell, plant and ecosystem level. Problems could result if, for example, herbicide-resistance genes got into weeds. So far, research on this is inconclusive, with scientists divided - often bitterly. But there is scientific consensus that once widely released, recalling transgenes or foreign DNA sequences, whose safety is still subject to scientific debate, will not be feasible.

What is the volume of 4.78g of O2 gas at STP?

Answers

Answer:

Explanation:

The trick here is to realize that if you know the volume of a gas at STP, you can use the fact that

1

mole of any ideal gas occupies

22.7 L

under STP conditions to calculate how many moles of gas you have in your sample.

Under STP conditions:

1 mole of an ideal gas = 22.7 L

−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−

In your case, you know that your sample of gas occupies

2.28 L

under STP conditions, which are currently defined as a pressure of

100 kPa

and a temperature of

0

C

.

This means that your sample will contain

2.28

L

molar volume of a gas at STP

=

0.10044 moles gas

Now, the molar mass of the gas is the mass of exactly

1

mole of the gas. In your case, you know that you get

3.78 g

for every

0.10044

moles, which means that you have

1

3.78 g

0.10044

=

37.6 g

Since this is the mass of

1

mole of gas, you can say that the molar mass of the gas is

Answers

Answer:

1.2 mol N2 = 26.88 L

3 mol H2 =  67.2 L

0.5 mol CO2 = 11.2 L

10.3 L NO2 = 0.46 moles

67.2 L SO2 = 67.2 / 22.4 = 3 moles

89.6 L NO = 89.6 /22.4 = 4 moles

44.8 L NO2  = 92 grams

201.6 L H2 = 18 g

65 grams CO = 51.9 L

152 grams F2  = 89.6 L

Explanation:

1 mole of a gas occupies a volume of 22.4 L

(N = 14, O = 16, C = 12, H = 1, F = 19)

1.2 mol N2= 1.2 * 22.4 L = 26.88 L

3 mol H2 = 3 * 22.4 L = 67.2 L

0.5 mol CO2 = 0.5 * 22.4  L = 11.2 L

10.3 L NO2 =  10.3 / 22.4 L = 0.46 moles

67.2 L SO2 = 67.2 / 22.4 = 3 moles

89.6 L NO = 89.6 /22.4 = 4 moles

1 mole or 22.4 L of NO₂ has a mass of 46 g

44.8 L NO2 = (44.8 /22.4) * 46 grams = 92 grams

1 mole or 22.4 L of H₂ has a mass of 2 g

201.6 L H2 = (201.6 / 22.4) * 2 grams = 18 g

1 mole or 22.4 L of CO has a mass of 28 g

65 grams CO = 65/28 * 22.4 L = 51.9 L

1 mole of F₂ has a mass of 38 grams

152 grams F2 = 152/38 * 22.4 L = 89.6 L

Answers

Explanation:

Scientists often look at how much of isotopes of : Carbon-14  have decayed

To determine the age of fossils archeologist make use of the carbon-14 dating ( i.e. making use of naturally occurring radioisotope ¹⁴C ) which is used to determine the age of fossils or material that were once in living on earth.

Carbon has about three (3) isotopes ( Carbon-12, Carbon-13 and Carbon-14 ) .but Carbon-14 isotope is most useful in determining the age of fossils and once-living things

Hence we can conclude that scientists often look at how much of isotopes of Carbon-14 have decayed to help estimate the age of fossils.

Answers

Based on The Law of Conservation of Mass Lavoisier, the mass of oxygen required is 3,2 g

The two main postulates that was given by Antoine Lavoisier are, oxygen play an important role in combustion and the other is mass of the reactant and product is conserved. Therefore the mass of oxygen is 3.2 g.

What is law of conservation of mass?

According to Law of conservation of mass, mass can neither be created nor be destroyed. Mass can only be transformed from one form to another. The law of conservation of mass was given by Antoine Lavoisier.

Every reaction in nature follow the law given by Antoine Lavoisier that is mass is always conserved. Another postulated that was given by Antoine Lavoisier is the role of oxygen in combustion reaction. Combustion can not happen without presence of oxygen. According to Law of Conservation of Mass Lavoisier, the mass of oxygen required is 3.2 g.
