Samples of simulated lake water are exposed to SO2(g). Two graduated cylinders containing samples of simulated lake water had CaCO3(s) added, and dissolves to form Ca2+ ions and CO32- ions. The chemical reaction of water exposed to SO2(g) is:H2O(l) + S02(g) --> H2S04(aq) (sulphuric acid) , producing Hydronium ions in solution. Hydronium ions react with the CO32- ions which then produces,options:HCO3-(aq) (weak acid)H2CO3(aq) (weak acid)HCO3-(aq) (strong acid)H2CO3(aq) (strong acid) |

The co ordinates of the points of a line segment in the ratio 2:1 |
|
Answer» Using the section formula, if a point (X,y) divides the line joining the points (X1,y1) and (X2,Y2) internally in the ratio m:n, then (x,y)=(m+nmx2+nx1,m+nmy2+ny1) Substituting (x1,y1)=(−2,1) and (x2,y2)=(1,4) and m=2,n=1 in the section formula, we get the point (2+12(1)+1(−2),2+12(4)+1(1))=(0,3) |

7. In Rohan's birthday party, 90% of his friends came and three friends did not come. Findthe total number of friends Rohan has. |
|
Answer» Answer: Step-by-step explanation: Given: Friends came = 90% of total friends Friends who didn't come = 3 To find : Total NUMBER of friends Rohan has Solution : LET the total number be y. As 90% came, ⇒ 100 - 90 ⇒ 10% 10% didn't come It is also given that 3 friends didn't come. ⇒ 10% of y = 3 ⇒ 10/100 × y = 3 ⇒ 10y = 3 × 100 ⇒ 10y = 300 ⇒ y = 300/10 ⇒ y = 30 Total Friends = 30 Friends who attended the party - ⇒ 90% of 30 ⇒ 90/100 × 30 ⇒ 9/10 × 30 ⇒ 9 × 3 ⇒ 27 27 friends attended the party. Therefore, Rohan has 30 friends. |
