You've just solved a problem and the answer is the mass of an electron, me=9.11×10−31kilograms. How would you enter this number

mihalych1998 [28]

The mass of an electron can be expressed in the box as $\boxed{{m_e} = 9.1 \times {{10}^{ - 31}}{\text{ kg}}}$ .

Further explanation:

Atom is the smallest particle that can be present in any element. It is also known as the building unit of matter. Each atom has a central part that is known as the atomic nucleus. There are three subatomic particles that constitute the atom. These particles are protons, neutrons, and electrons. The atomic nucleus consists of protons and neutrons, both are collectively called nucleons. Electrons revolve around the nucleus of an atom in definite orbits.

Protons are positively charged subatomic particles, electrons are negatively charged and neutrons have no charge. Since electrons carry a unit negative charge, these create an electric field around them. These also participate in nuclear reactions. The mass of an electron $\left( {{m_e}} \right)$ is $9.1 \times {10^{ - 31}}{\text{ kg}}$ , that of protons is $1.6726219 \times {10^{ - 27}}{\text{ kg}}$ and that of neutrons is $1.674927471 \times {10^{ - 27}}{\text{ kg}}$ . The electrons are responsible for chemical properties of elements. The distribution and arrangement of electrons is used to predict whether the element will be inert or reactive.

Therefore the required answer is $\boxed{{m_e} = 9.1 \times {{10}^{ - 31}}{\text{ kg}}}$ .

Select the fastest way to differentiate between the organic and aqueous layers of an extraction.a. Hold a white piece of paper b

valentinak56 [21]

Answer:

b. Add a few drops of one of the layers to a test tube containing 1 mL of water. Shake the test tube to determine the solubility of the layer in water

Explanation:

Option a is not true, it depends on the compound being extracted.

Option c is not true, although most of the solvents used in extractions have lower boiling point than water there are exceptions, for example toluene.

Option d is not true. Again most of the solvents used in extractions are less dense than water, there are many exceptions, for example chloroform, so for equal volumes the chloroform layer will weigh more.

Option b. is the correct one.

One will test the miscibility of the layer in water. If it inmiscible then one would know is the organic layer. If it is the aqueous layer then it will completely be miscible.

Compare and contrast the general properties of alloys and pure metals

murzikaleks [220]

Alloys are used much more than pure metals because they are generally stronger and less likely to react with air or water.
