List elements and compounds available in punjab? |
|
Answer» Explanation:Elements are complete chemical substances which relate to a single entry in the modern PERIODIC table. Elements consist of one kind of ATOMS only. They cannot be broken down into simpler fragments and can EXIST as atoms or as molecules.A compound is a material formed by chemically bonding two or more chemical elements. The type of bond keeping elements in a compound TOGETHER may vary: covalent bonds and ionic bonds are two COMMON types. The elements are always present in fixed ratios in any compound. |

Newton’s third law of motion explains the two forces namely ‘action’ and ‘reaction’ coming into action when the two bodies are in contact with each other. These two forces: (a) Always act on the same body (b) Always act on the different bodies in opposite directions (c) Have same magnitude and direction (d) Acts on either body at normal to each other |
|
Answer» answer AExplanation:The statement means that in every interaction, there is a pair of forces acting on the two interacting objects. ... The DIRECTION of the FORCE on the first object is opposite to the direction of the force on the SECOND object. Forces ALWAYS COME in pairs - equal and opposite action-reaction force pairs. |

If fx=x4-2x^3+3x^2-ax+b is divided by x-1 and x+1,it leaves remainder 5 and 19 respectively.Find the value of a and b. |
|
Answer» tion:Given that the equationf(x) = x4 – 2x3 + 3x2 – ax +BWHEN F(x) is divided by (x+1) and (x-1) , the remainders are 19 and 5 respectively .∴ f(-1) = 19 and f(1) = 5(-1)4 – 2 (-1)3 + 3(-1)2 – a (-1) + b = 19⇒ 1 +2 + 3 + a + b = 19∴ a + b = 13 ——- (1)According to given CONDITION f(1) = 5f(x) = x4 – 2x3 + 3x2 – ax⇒ 14 – 2 3 + 3 2 – a (1) b = 5⇒ 1 – 2 + 3 – a + b = 5∴ b – a = 3 —— (2)solving equations (1) and (2)a = 5 and b = 8Now substituting the values of a and b in f(x) , we get∴ f(x) = x4 – 2x3 + 3x2 – 5X + 8Also f(x) is divided by (x-3) so remainder will be f(3)∴ f(x)= x4 – 2x3 + 3x2 – 5x + 8⇒ f(3) = 34 – 2 × 33 + 3 × 32 – 5 × 3 + 8= 81 – 54 + 27 – 15 + 8= 47Therefore, f(x) = x4 – 2x3 + 3x2 – ax +b when a=3 and b= 8 is 47 |

Elements and compounds occouring in punjab? |
|
Answer» tion:Elements are the simplest complete chemical substances. Each element corresponds to a single entry on the PERIODIC table. An element is a material that consists of a single TYPE of atom. Each atom type contains the same number of protons.Chemical bonds link elements together to form more complex molecules called compounds. A compound consists of TWO or more types of elements held together by covalent or ionic bonds.Elements cannot be divided into smaller units without large amounts of energy. Compounds, on the other hand, can have their bonds broken with practical amounts of energy, such as the heat from a fire.Matter can be broken down into two CATEGORIES: pure substances and MIXTURES. Pure substances are further broken down into elements and compounds. Mixtures are physically combined structures that can be separated back into their original components. |

Write a conclusion on properties and uses of covalent compounds |
|
Answer» What is a Covalent Compound? Covalent compounds are the ones having strong intra-molecular bonds. This is because the atoms WITHIN the covalent molecules are very tightly held together. Each MOLECULE is indeed quite separate and the force of attraction between the individual molecules in a covalent compound tends to be weak. We require very little energy in separating the molecules. This is because of the attractive forces between the molecules with the absence of overall electric charge. Covalent compounds are usually gaseous molecules at room temperature and pressure. They MIGHT also be liquids with low relatively low boiling points. These characteristics could be attributed to their weak intermolecular forces which hold these atoms together. However, we also have a lot of solid covalent compounds. They have low melting points. However, it is interesting to note that a small number of these have a completely different structure. They form HUGE structures where a huge number of atoms are held together. This is possible due to the presence of shared electrons. These giant molecular structures are basically lattices made up of molecules which are held together by covalent bonds structure. These covalent bonds are very strong. They also tend to be very hard with high melting points which are different from most of the covalent compounds. The example of this kind of covalent compounds includes diamond and GRAPHITE of carbon atom network. They also include silica of silicon and oxygen atoms network.Explanation: |
