Explanation:

Keep in MIND that although acceleration is in the DIRECTION of the change in VELOCITY, it is not always in the direction of motion. When an object slows down, its acceleration is OPPOSITE to the direction of its motion. This is known as deceleration.

Explanation:

A FRIEDEL-Crafts reaction is an organic coupling reaction involving an electrophilic aromatic substitution that is used for the attachment of substituents to aromatic rings. The TWO PRIMARY types of Friedel-Crafts reactions are the alkylation and acylation reactions. These reactions were DEVELOPED in the year 1877 by the French CHEMIST Charles Friedel and the American chemist James Crafts.

Explanation:

I MERELY GUESSED it

Answer:n the year 1897 J.J. Thomson INVENTED the electron by PLAYING with a tube that was Crookes, or CATHODE RAY. He had shown that the cathode RAYS were charged negatively. Thomson realized that the accepted model of an atom did not account for the particles charged negatively or positively.

No option is correct. The SHORTEST wavelength of the light EMITTED is when the electron jumps from INFINITY to 3. For Li²⁺, λ = 9/R × 3² m. = 81/R m.

Definition: Crystallization or crystallisation is the (natural or artificial) process by which a SOLID forms, where the atoms or molecules are highly organized into a structure KNOWN as a crystal.

Explanation:

Answer:

STOICHIOMETRY is a section of CHEMISTRY that involves using relationships between reactants and/or products in a chemical reaction to determine desired quantitative data. In Greek, stoikhein means element and metron means measure, so stoichiometry literally translated means the measure of elements. In order to use stoichiometry to RUN calculations about chemical reactions, it is important to FIRST understand the relationships that exist between products and reactants and why they exist, which require understanding how to balance reactions.

HOPE my answer helped you

Answer:

When two ELECTRICAL charges, of OPPOSITE sign and EQUAL magnitude, are separated by a distance, an electric DIPOLE is established. The size of a dipole is measured by its dipole moment ( μ ). Dipole moment is measured in Debye units, which is equal to the distance between the charges multiplied by the charge (1 Debye EQUALS  3.34×10−30Cm ). The dipole moment of a molecule can be calculated by Equation

Answer:

Hydroxide is a diatomic anion with chemical FORMULA OH−. It consists of an oxygen and hydrogen atom held together by a covalent bond, and CARRIES a negative electric charge. It is an important but usually minor constituent of water.

exp. Sodium hydroxide, NAOH, also known as caustic soda or lye, is of GREAT industrial importance. Calcium, barium, and strontium—all alkaline EARTH metals—form soluble hydroxides that are strong bases but are less stable than the alkali hydroxides.

you will get decanoic acid, SINCE KMnO4 is a very powerful oxidising agent

Answer:

how was the PRESENCE of the proton detected?

Degen's team placed a thin SLICE of the material that CONTAINED hydrogen just above the diamond crystal's surface. When they turned on the magnetic field, they observed that the brightness of the red light changed DUE to a change in magnetic fields. That highlighted the presence of a single proton nearby.

what are their characteristics?

Protons are found in the nucleus of the atom. This is a tiny, dense REGION at the center of the atom. Protons have a positive electrical charge of one (+1) and a mass of 1 atomic mass unit (amu), which is about 1.67×10−27 kilograms.
