s344n2d4d5 [400]

Answer:A

Explanation:

mass of object=3 kg

distance moved=50 cm

time t=1 s

s=ut+\frac{at^2}{2}

0.5=0+\frac{a\cdot 1^2}{2}

a=1 m/s^2

Let T is the tension in rope

T-mg=ma

Let M be the other mass

Mg-T=Ma

T=M(g-a)

M=m\frac{g+a}{g-a}

M=3\times \frac{9.8+1}{9.8-1}

M=3\times 1.227

M=3.67 kg

AlBr3 + K2SO4 → KBr + Al2(SO4)3
STALIN [3.7K]

On the left, you have

  • 1 Al
  • 3 Br
  • 2 K
  • 1 S
  • 4 O

while on the right, you have

  • 1 K
  • 1 Br
  • 2 Al
  • 3 S
  • 12 O

To get a balanced equation, you'll need 6 KBr on the right, which would require 2 AlBr3 and 3 K2SO4 on the left, so you end up with

2\,\mathrm{AlBr}_3+3\,\mathrm K_2\mathrm{SO}_4\to6\,\mathrm{KBr}+\mathrm{Al}_2(\mathrm{SO}_4)_3
