Answer:

AlCl₃

Explanation:

Impurities depressing the freezing point of a solvent  is called colligative property . It depends upon no of particles or ions of impurities. When the given compounds are dissolved in water , they break into ions and depress the freezing point . No of ions formed by one molecule of compound AlCl₃  on ionization is  highest ( 4 ) . So this compound will have highest strength to lower the  freezing point of solvent.

AlCl₃  = Al⁺⁺⁺  +   3Cl⁻

Total no of ions after ionization

= 1 + 3 = 4 .

The open-circuit voltage of a car battery is measured to be 12 V. During engine startup, the battery delivers 10 A to the starte
dmitriy555 [2]

Answer:

- the Thevenin equivalent circuit for the battery is uploaded below

- the battery delivered 117 watts of power to the starter motor

Explanation:

Given the data in the equation

diagram of the Thevenin equivalent circuit for the battery is uploaded below.

Current I = 10 A

Voltage 1 = 12 V

voltage 2 = 11.7 v

R = (V1 - V2) / I

R = (12-11.7)/10

R = 0.3 / 10

R = 0.03Ω

Thevenin equivalent circuit

R_{L} = V2 / I = 11.7 / 10

R_{L} = 1.17Ω

so, power delivered to the starter motor will be;

p = (V2)² / R_{L}

P = ( 11.7 V )² / 1.17Ω

p =  136.89 / 1.17

p =  117 watts

Therefore, the battery delivered 117 watts of power to the starter motor

SOVA2 [1]

Explanation:

u=0 m/s

v=9.6 m/s

s= 40.5 m

a=?

V^2=u^2 +2as

9.6^2=0+2×a×40.5

92.16=81a

a=92.16/81

a=1.14m/s^2

How do I find the approximate velocity of "the object", on the graph at 5 seconds?
MakcuM [25]

First, foremost, and most critically, you must look at the graph, and critically
examine its behavior from just before until just after the 5-seconds point.

Without that ability ... since the graph is nowhere to be found ... I am hardly
in a position to assist you in the process.
