8 gm of caustic soda (molar mass 40) is dissolved in water and solution is made to 800cm³. calculate the molarity of the solution |
|
Answer» In the given question
Number of moles of solute = Mass of solute ÷ Molar mass ⇒ Number of moles of solute = 8 ÷ 40 ⇒ Number of moles of solute = 0.2 moles We KNOW that 1 cm³ = 1 ML So, VOLUME of solution = 800 cm³ = 800 mL = 0.8 litres Molarity = Number of moles of solute ÷ Volume of solution ⇒ Molarity = 0.2 ÷ 0.8 ⇒ Molarity = 0.25 M ∴ Molarity of solution = 0.25 M REMEMBER:

How water is helpful in controlling fire |
|
Answer» Water can actually do three things with fire: FEED it, not affect it, or quench it, depending on the FUEL. For burning solids, such as paper, WOOD, or coal, water will EXTINGUISH the fire by TWO methods: cooling and, if enough is present, depriving the fire of oxygen. . . hope it will be helpful Mark me as a brainliest also like my answer (◕ᴥ◕) |

Which two elements will form covalent bond |
|
Answer» Covalent BONDS USUALLY occur between nonmetals. For example, in water (H2O) each hydrogen (H) and oxygen (O) share a pair of electrons to make a molecule of two hydrogen atoms single bonded to a single oxygen atom. In general, ionic bonds occur between ELEMENTS that are far apart on the PERIODIC table. |

What are structural Isomers? Name the products formed when an acid reacts with base. |
|
Answer» Answer: Structural isomer is another compound whose molecule has the same number of atoms of each element with DISTINCT bonds between them. Anytime an acid REACTS with a BASE SALT and water is produced. for example HCl + NaOH > NaCl + H2O HCL= is the acid here ( remember it is in the aqueous state) NaOH = is the base here but specifically an ALKALI H20 = as you already know is water. Note that an alkali is a soluble base, and that all alkali are bases but not all bases are alkali |

What is the formula between alkali metals(Na and K ) and halogen(F,Br,Cl,I) write the eight formulas and name. |
|
Answer» Answer: Four elements, hydrogen, carbon, oxygen and NITROGEN, are the MAJOR components of most organic compounds. Consequently, our understanding of organic chemistry must have, as a foundation, an appreciation of the electronic structure and properties of these elements. The truncated PERIODIC table shown above provides the orbital electronic structure for the first eighteen elements (hydrogen through ARGON). According to the Aufbau principle, the electrons of an atom occupy quantum levels or orbitals starting from the lowest energy level, and PROCEEDING to the highest, with each orbital holding a maximum of two paired electrons (opposite spins). |

What is Schottky defect ? |
|
Answer» Answer: Schottky defect is basically a vacancy defect shown by ionic SOLIDS. In this defect, an EQUAL number of cations and anions are missing to maintain ELECTRICAL neutrality. It decreases the density of a substance. Significant number of Schottky defects is present in ionic solids. For example, in NaCl, there are approximately 106 Schottky pairs per cm3 at room temperature. Ionic substances containing similar-sized cations and anions show this type of defect. For example: NaCl, KCl, CsCl, AGBR, etc. Explanation: |

Convection takes place in solid and liquids .false ,give reson |
|
Answer» Mark me as brilliantist Explanation: In the process of convection, MOLECULES MOVE from a hotter place to a colder region. Therefore, convection is impossible in SOLIDS because the molecules are rigid and vibrate when HEATED. In liquids and gases, molecules are comparatively less rigid and can move easily, thereby making convection possible in them. |
