Write the acid and base used to make Na2CO3 salt |
|
Answer» HEY mate here is your answer》》 When sodium carbonate dissolves in water it DISSOCIATES into two sodium (Na+) ions and a carbonate (CO3–2) ion;- Na2CO3 (s) —-> 2 Na+(aq) + CO3–2(aq) The carbonate ion is able to remove protons (H+) from water to form bicarbonate ions and hydroxide ions. HENCE it is the conjugate base of the bicarbonate ion; CO3–2(aq) + H2O(l) ←-> HCO3-(aq) + OH-(aq) The overall increase in OH- ions due to these reactions results in an increase in the pH of the solution, and cause it to BECOME alkaline. Hope this answer will help you..《《 |

What is the difference between unified mass and atomic mass unoy? |
|
Answer» Answer: Atomic mass of an element expressed in grams is CALLED gram atomic mass. Atomic mass unit (a.m.u) is the quantity of mass equal to 1/12th of the mass of an atom of carbon (C-12). ... Hence, the REFERENCE was changed to C-12 and a new symbol 'u' (UNIFIED mass) REPLACED the old symbol 'a.m.u'. |

Heyy,Need ur help guys....Plzz explain me what is co-ordination no. of an element ?How to find co-ordination no. of any elements ???Need a good ans... & in easy language...Thankyou❤ |
|
Answer» COORDINATION number. Coordination number, also called Ligancy, the number of atoms, ions, or MOLECULES that a central atom or ion holds as its nearest NEIGHBOURS in a complex or coordination compound or in a crystal. 2)To do this, find the molecule or ion directly beside the metal symbol in the chemical formula of the coordination compound. If the central atom is in the middle of the formula, there will be neighboring atoms/molecules/ions on both SIDES. Add the number of atoms of the nearest atom/molecule/ions |

Random movement of the particles of matter decreases when it is heated is it true or false |
|
Answer» False Explanation: When gases, liquids and SOLIDS are heated, they EXPAND. As they cool, they contract or get smaller. The expansion of the gases and liquids is because the particles are moving around very fast when they are heated and are able to MOVE further apart so they take up more ROOM |

|
Answer» Answer: Combustible substance: Substances that burn easily or catch fire easily are called combustible substances. Paper, clothes, wood, LPG are all combustible substances. Without these substances, a fire cannot be started. 1. Camphor is a waxy, flammable, white or transparent solid with a strong aromatic odour and combustible material. 2. Glass consists mostly of oxides such as silica. Because the elements are in their highest OXIDATION states, they will not react with oxygen. Thus, glass is not combustible. 3. Alcohol is a hydrocarbon, especially the ones with LOW MOLECULAR mass, are very combustible. They combine with oxygen readily and make carbon DIOXIDE and water. If there is not ENOUGH oxygen, they can also make some carbon monoxide. |

List four varieties of coal and mention its uses |
|
Answer» Answer: Anthracite: The highest rank of coal. It is a hard, brittle, and black lustrous coal, often referred to as hard coal, containing a high percentage of fixed CARBON and a low percentage of volatile matter. Bituminous: Bituminous coal is a middle rank coal between subbituminous and anthracite. Bituminous usually has a high heating (Btu) value and is the most common type of coal used in electricity generation in the United States. Bituminous coal appears shiny and smooth when you first see it, but look CLOSER and you may see it has layers. Subbituminous: Subbituminous coal is black in color and dull (not shiny), and has a higher heating value than lignite. Lignite: Lignite coal, aka brown coal, is the lowest GRADE coal with the LEAST concentration of carbon. Explanation: |

Define a Radical with two examples in an easy manner. |

Answer» Explanation: Science (from the Latin word scientia, meaning "knowledge")[1] is a systematic enterprise that builds and organizes knowledge in the form of testable explanations and predictions about the universe.[2][3][4] The Universe represented as multiple disk-shaped slices across time, which passes from left to right The earliest roots of science can be traced to Ancient EGYPT and Mesopotamia in around 3500 to 3000 BCE.[5][6] Their contributions to mathematics, astronomy, and medicine entered and shaped Greek natural philosophy of classical antiquity, whereby formal attempts were made to provide explanations of events in the physical world based on natural causes.[5][6] After the fall of the Western ROMAN Empire, knowledge of Greek conceptions of the world deteriorated in Western Europe during the early centuries (400 to 1000 CE) of the Middle Ages[7] but was preserved in the Muslim world during the Islamic Golden Age.[8] The recovery and assimilation of Greek works and Islamic inquiries into Western Europe from the 10th to 13th century revived "natural philosophy",[7][9] which was later transformed by the Scientific Revolution that began in the 16th century[10] as new ideas and discoveries departed from previous Greek conceptions and traditions.[11][12][13][14] The scientific method soon played a greater role in knowledge creation and it was not until the 19th century that many of the institutional and professional features of science began to take shape;[15][16][17] along with the CHANGING of "natural philosophy" to "natural science."[18] Modern science is typically divided into three major branches that consist of the natural sciences (e.g., biology, chemistry, and physics), which study nature in the broadest sense; the social sciences (e.g., economics, psychology, and sociology), which study individuals and societies; and the formal sciences (e.g., logic, mathematics, and theoretical computer science), which study abstract concepts. There is disagreement,[19][20][21] however, on whether the formal sciences actually constitute a science as they do not rely on empirical evidence.[22][20] Disciplines that use existing scientific knowledge for practical purposes, such as engineering and medicine, are described as applied sciences.[23][24][25][26] Science is based on research, which is commonly conducted in academic and research institutions as well as in government agencies and companies. The practical impact of scientific research has led to the emergence of science policies that seek to influence the scientific enterprise by prioritizing the development of commercial products, armaments, health care, and environmental protection. |
