Can someone help me determine the name of the formula

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

Answer:

B. 11.18 mols of Cu

Explanation:

Given parameters:

Number of particles in Cu  = 6.73 x 10²⁴ particles

Unknown:

Number of moles  = ?

Solution:

A mole of a substance is known to contain the Avogadro's number of particles. To solve this problem;

          6.02 x 10²³ particles is contained in 1 mole of a substance

         6.73 x 10²⁴ particles  will be contained in [tex]\frac{6.73 x 10^{24} }{6.02 x 10^{23} }[/tex]   = 11.18moles of Cu

1. Stoichiometrically calculate the mass (in grams) of ascorbic acid in the powdered sample. 

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.

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.

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.

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.

Therefore the mass of oxygen is 3.2 g.

Explanation:

Given parameters:

Distance traveled  = 500m

Time taken  = 60s

Unknown:

Speed of the sound  = ?

Solution:

The speed the sound can be derived using the expression below:

 Speed  = [tex]\frac{distance}{time}[/tex]  

So;

    Speed  = [tex]\frac{500}{60}[/tex]    = 8.33m/s

Temperature change  = ?

Solution:

To solve this problem, we simply use the expression below:

  The quantity of energy is given as:

          Q  = m C Δt

Q is the quantity of energy

m is the mass

C is the specific heat capacity of aluminum  = 0.9J/g°C

B) Poor conductors

Explanation:

According to the characteristics of non-metals , non-metals are poor conductors of electricity and are mostly gases at room temperature and are also brittle.

An element is the simplest form of matter.Elements are further classified as metal,non -metals and metalloids. Non-metals  do not possess luster and are dull . They are not malleable and ductile and are soft due to the covalent bonding present in them . Non-metals  owing to their soft nature have low melting points.

As they have large intermolecular spaces they are mostly gases at room temperature and are also brittle due to the presence of weak bonding present in them.They  are poor conductors as they do not have mobile electrons.They have low tensile strength due to presence of covalent bonding.

Answer:

Number of protons

Explanation:

There are three sub atomic particles. These are;

- Protons

- Electrons

- Neutrons

Among these three particles, only one determines the identity of the element. This is the Protons. The number of protons which is also called the atomic number determines the identity of an element. For instance, atom with one proton is Hydrogen and n other element can have atomic number of one.

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
