Write the balanced equation for the. following reaction in each case. (i) Potassium bromide + Barium iodide—-> Potassium iodide + Barium bromide. |
|
Answer» Explanation: (a) Potassium bromide(aq) + Barium IODIDE(aq) → Potassium iodide(aq) + Barium bromide(s) 2KBr (aq)
+BaI 2
(aq)
→2KI (aq)
+BaBr 2
(s)
In this reaction, both the reactants exchanges ions to for two new products, HENCE, it is a double displacement reaction (b) zinc carbonate(s) → Zinc oxide(s) + Carbon dioxide(g) ZnCO 3
(s)
→ZnO (s)
+CO 2
(g)
In this reaction, a single substance yields two different product. hence, it is a decomposition reaction (c) HYDROGEN(g) + Chlorine(g) → Hydrogen chloride(g) H 2
(g)
+Cl 2
(g)
→2HCl (g)
In this reaction, two different reactants REACT with each other to form a single product. Hence, it is called a combination reaction (d) MAGNESIUM(s) + Hydrochloric acid(aq) → Magnesium chloride(aq) + Hydrogen(g) Mg (s)
+2HCl (aq)
→MgCl 2
(aq)
+H 2
(g)
In this reaction, more reactive Mg is replacing less reactive H. Hence, it is displacement reaction |

2 A train starts starts from rest. It moves through 1 km. in 100 second with unifrom acceleration. what will be speed at the end of 100 second? |
|
Answer» Explanation: initial VELOCITY ( v) 0m/s s= 1 km convert it into m s= 1000M t= 100 sec we have to find acceleration? final velocity ( vf) we can use the formula s= vit +1/2 ×at² 100 = (0) (100) +1/2 × a(100)² 1000= 0+1/2 ×a (1000)² 1000 = 0+ 1/2 ×a (1000) 1000 = a × 5000 a = 5000 / 1000 a = 0.2 ms ‐¹ now vf = vi + at vf = 0+(0.2)×100 vf = 20 m/ s ‐¹ HOPE IT HELPS U ..

A particle is projected with velocity of 10 m/s in a resistive medium which offers retardation given by a = 5v. If velocity (in m/s) of particle as function of time t is given as v= 10e-kt then find k.help |
|
Answer» Given : v o
=10 m/s θ o
=60 o
ANGLE of inclination α=30 o
TIME of flight T= g cosα 2v o
sinθ o
⟹ T= 10×cos30 o
2×10×sin60 o
=2 s |

Pls solve thisThe figure represents F/x graph Find work done to move a body from A to B under action of variable forcePls ans this |
|
Answer» The figure represents Force - DISPLACEMENT graph . Find work done to move a body from A to B under action of VARIABLE force . Work Done = - 4π J The body moves from A to B . Radius of semicircle = 4 cm Radius of quadrant = 4 cm Work done to move body from A to B under action of variable force . We KNOW that area under force - displacement graph gives work done . Therefore , From figure , We see that body is moving from right to LEFT . Therefore , Work done from A to O becomes negative . The work done from O to B is also negative but the quadrant is also negative . Therefore , negative signs cancel each other . Work done = ( - 8π + 4π ) J Work done = - 4π J Hence , Work done to move body from A to B under action of variable force is -4π Joule .
Force is the push or pull on an OBJECT with mass that causes it to change its velocity.
Displacement is the shortest distance between initial and final position of the object .
Work is said to be done by a force on an object only when the object moves in any direction except in the direction perpendicular to the force .
One joule is defined as the work done by one newton force in moving an object through a distance of one metre along the direction of applied force . |

It is easier to move the box that is already in motion than to move it from vllt. |
|
Answer» Answer: It is easier to move a box which is already in motion then to move it from REST because when the box is in motion its NET SPEED WORKING on it is more, so it is easier to move a box which is already in motion . Static friction is little more than sliding friction for any given pair of surfaces. |
