Prior to Thomson's discovery, the atom was thought to be indivisible. Explain the significance of Thomson's concept of the electron.

Answers

Answer 1

In 1897, J.J. Thomson's discovery of the electron was revolutionary.

What is thomson's concept?

Thomson's concept of the electron showed that the atom was not indivisible, but instead was composed of smaller particles. This discovery provided the first piece of evidence to support the atomic theory, which states that all matter is made up of atoms.

Thomson's concept of the electron also allowed scientists to understand the behaviour of electricity better. Electrons are negatively charged particles, and Thomson's discovery showed that electricity is a flow of electrons. This knowledge allowed scientists to create new technologies based on the understanding of electrons, such as computers and cell phones.

The significance of Thomson's concept of the electron can be summed up in three words: evidence, electricity, and technology. Thomson's discovery provided the first piece of evidence for the atomic theory, allowed for a better understanding of electricity, and paved the way for the creation of many new technologies.

Now assume that all of the potential energy went into kinetic right as it is about to hit the bottom. What would be the value for the kinetic energy? a. less
b. same
c. more
d. not information

Answers

The potential energy will go into kinetic right as it is about to hit the bottom. Then, the value will be the b) same for the kinetic energy.

When an object falls, its potential energy decreases, and its kinetic energy increases. A decrease in the potential energy is exactly the same as an increase in the kinetic energy. According to the law of conservation of energy, just before the lamp stops, the potential energy at the top of the lamp and the kinetic energy at the bottom must be equal. At the foot of the hill, the potential energy is zero and the final energy is all kinetic energy. We can equate these two values ​​according to the law of conservation of energy.

The substitution allows each carbon atom to accept more than four valence electrons.

Answers

Answer:

E. The substitution allows each carbon atom to accept more than four valence electrons.

Explanation:

Halogens (except for fluorine) have seven valence electrons, which gives them the flexibility to participate in more than four covalent bonds. Hydrogen only has one valence electron, so it tends to form only four covalent bonds. In a substitution reaction, each halogen provides the carbon atom with additional electrons, allowing it to accept more than the usual four.

Given that 1 kWh = 3. 6 MJ and that 1 Btu = 1055 J, show that 1 kWh = 3412 Btu.

Answers

Given that 1 kWh = 3. 6 MJ and that 1 Btu = 1055 J, It is shown that 1 kWh = 3412 Btu.

1 kilowatt (kWh) = 3.6 mega Joules (MJ)

1 British thermal unit (Btu) = 1055 Joules (J)

As we know that:

1 MJ = 1000000 J

Since

1 kWh = 3.6 x 1000000 J

Calculate for 1 J

1 J = 1 ÷ 1055 Btu

1 kWh = 3.6 x 1000000 x (1 ÷ 1055) Btu

What is Diatomic elements?

Diatomic elements are chemical elements that exist in the form of two atoms held together by covalent bonds. The most common elements that exist as diatomic molecules are hydrogen, oxygen, nitrogen, fluorine, chlorine, bromine, and iodine. These elements are found in nature and play important roles in the formation of compounds used in everyday life.

This bond is usually covalent in nature, and the two atoms form a stable molecule. This type of molecule is very stable and present in the form of gas, at room temperature and pressure. Examples of diatomic elements are hydrogen, oxygen, nitrogen, fluorine, chlorine, and bromine. Due to the fact that these elements are already in a stable, two-atom form, they exhibit different chemical and physical properties than other elements. For example, diatomic oxygen is highly reactive and can easily combine with other elements, while diatomic nitrogen is relatively inert. This difference in reactivity is due to the fact that the two atoms in the diatomic form share electrons more easily than atoms in other elemental forms.

Answers

If we need 18.9 grams of HCl for a reaction, and we have a 1.5 M solution of HCl, the mL of this solution should we use is 345.3 mL.

Given that :

mass of the HCl =  18.9 grams.

molar mass of the HCl = 36.45 g/mol

moles of the HCl = mass / molar mass

                             = 18.9 / 36.45

the molarity of the HCl = 1.5 M

The molarity is given as:

molarity = moles / volumes

volume in L = moles / molarity

                    = 0.518 / 1.5

To find the molarity of sucrose in the Coke, we first need to find the number of moles of sucrose present in the can. We can use the mass of sucrose (39.24 g) and the molar mass of sucrose (342.3 g/mol) to find the number of moles of sucrose:

= (39.24 g) / (342.3 g/mol)

= 0.114 mol

Next, we need to find the volume of the can in liters. We can convert the volume in fluid oz. to liters using the conversion factor 1 fluid oz.

= 0.0295735 L:

= (12.0 fluid oz.) x (0.0295735 L/fluid oz.)
