What informalion do you get som thefollowing chemical equation 2 Na + H2O -> 2 NaoH+H2 |
|
Answer» Answer: Law of conservation of mass governs the balancing of a chemical equation. According to this law, mass can neither be CREATED nor be destroyed in a chemical reaction and obeying this law total mass of the elements or molecules present on the reactant side should be equal to the total mass of elements or molecules present on the product side. If the chemical equation is not balanced law of conservation is not applicable. Balancing the given equation Na + H2O –> NaOH + H2 Following are the easy steps to balance the equation: Step 1: Write the UNBALANCED Chemical Equation LET us consider an unbalanced equation Na + H2O –> NaOH + H2 Step 2: Write Down Number of Atoms Write down the number of atoms of each element present on both reactant as well as product side Atom Reactant side Product side Na 1 1 H 2 3 O 1 1 Step 3: Add Coefficients To Balance the Mass in a Chemical Equation Note that the coefficients that are to be added must be a whole number and one coefficient added applies to all the atoms present in that one PARTICULAR molecule. 2Na+2H2O—> 2NaOH+H2 After balancing the equation we GET the number of reactants and products as given in the table Atom Reactant side Product side Na 2 2 H 4 4 O 2 2 Since the number of atoms is equal on both the side of the equations, the given chemical equation is balanced. Hence the balanced chemical equation is 2Na+2H2O—> 2NaOH+H2 Explanation: hope this helps you please marks as BRAINLIEST |

two young man going in double ride over a bike along a straight road. one man sitting back fall down over a bike then the velocity of the bike increases or decreases. why? |
Answer» Given:Two YOUNG man going in double ride over a BIKE along a straight road. One man sitting back fall down from the bike. To find:Velocity of bike increases or decreases? Calculation:FIRST of all, when the man fell down from the bike, no external force was used and hence the total linear momentum of the system will remain conserved. Applying CONSERVATION OF LINEAR MOMENTUM:
So, final velocity of bike increases. |

Force of 294N is required to start moving an object of 100kg in a horizontal plane. Calculate the coefficient of friction. |
|
Answer» Given: Force of 294N is required to START moving an OBJECT of 100kg in a horizontal plane. To Find: coefficient of friction. Solution: Coefficient of friction, μ = F / N Where F is the frictional force and N is the normal reaction N = mg ⇒ N = 100 x 9.8 = 980 N Now, it is given that F = 294 N Putting these VALUES in the formula, μ = (294 / 980) = 0.3 Hence, the coefficient of friction is 0.3 |

Relation between alpha and gamma in thermal expansion |
|
Answer» Answer: As the temperature increases, the volume of the material ALSO increases. This is known as thermal expansion. It can also be explained as the fractional CHANGE in the length or volume per unit change in the temperature. The relation between alpha, BETA, and gamma is given in the form of a ratio and the ratio is 1:2:3 and can be expressed as: α=β2=γ3 Following is the relation between the three: L = L (1 + α.ΔT) Where, α is the coefficient of linear expansion A = A (1 + β.ΔT) Where, β is the coefficient of aerial expansion V = V (1 + γ.ΔT) Where, γ is the coefficient of cubical expansion V = V + γV.ΔT V = V (1 + γ.ΔT) L3 = L3 (1 + α.ΔT)3 L3 = L3 (1 + 3α.ΔT + 3α2.ΔT2 + α3.ΔT3) L3 = L3 (1 + 3α.ΔT) Since 3α2.ΔT2 and α3.ΔT3 are smaller than 1, we are not considering them. L3 = L3 (1 + 3α.ΔT) V = L3 (1 + 3α.ΔT) V (1 + γ.ΔT) = V (1 + 3α.ΔT) 1 + γ.ΔT = 1 + 3α.ΔT γ.ΔT = 3α.ΔT γ = 3α β = 2α A = A (1 + β.ΔT) L2 = L2 (1 + α.ΔT)2 A = L2 (1 + 2α.ΔT + α2.ΔT2) A = A (1 + 2α.ΔT) A (1 + β.ΔT) = A (1+ 2α.ΔT) Since α2.ΔT2 has a smaller volume, it is not considered β = 2α α : β : γ = 1 : 2 : 3 pls pls pls vote me and mark as Brainliest |

during the thunderstorm, the sound of thunder is heard much later than the flash of lightning is sun give reasons.... |
|
Answer» Lightning is seen earlier and THUNDER is HEARD LATER because the speed of sound is 330 m/s and the speed of light is 300,000,000 m/s. Light travels faster than a sound. Thus, light from the lightning REACHES first to you. The sound from the lightning takes longer to reach and hence heard later. |
