<h3><u>Answer;</u></h3>

10 percent

<h3><u>Explanation;</u></h3>
  • Probability is a number that describes how likely it is that an event will occur.
  • In this case; If each of 10 events is equally likely to occur, the probability of each individual event occurring is 1/10.
  • Therefore; as a percentage;

1/10 × 100 = 10 percent

  • Hence; The probability of each individual event occurring is 10 percent

If a car can go from 0 to 60 mi/hr in 8.0 seconds, what would be its final speed after 5.0 seconds if its starting speed were 50
tangare [24]

Answer:

87.5 mi/hr

Explanation:

Because a = Δv / Δt (a = vf - vi/ Δt), we need to find the acceleration first to know the change in velocity so we can determine the final velocity.

vf = 60 mi/hr

vi = 0 mi/hr

Δt = 8 secs

a = vf - vi/ Δt

= 60 mi/hr - 0 mi/hr/ 8 secs

= 60 mi/hr / 8 secs

= 7.5 mi/hr^2

Now that we know the acceleration of the car is 7. 5 mi/hr^2, we can substitute it in the acceleration formula to find the final velocity when the initial velocity is 50 mi/hr after 5 secs.

vi = 50 mi/ hr

Δt = 5 secs

a = 7.5 mi/ hr^2

a = vf - vi/ Δt

7.5 = vf - 50 mi/hr / 5 secs

37.5 = vf - 50

87.5 mi/ hr = vf

In a reaction that produces carbon dioxide, the theoretical yield is 59 grams. During the experiment, the reaction actually prod
Roman55 [17]

Answer:

mole ratio, which is equivalent to a 1;1 mole ratio, to a gram ratio. This means that when the reaction consumes 84.03 g of carbon monoxide, it should theoretically produce 132.03 g of carbon dioxide. Use this gram ratio to calculate the theoretical yield for your reaction.

Initial Activity- What mass of solute will dissolve in 100g of water at the following temperatures?
pantera1 [17]

The mass of solute will dissolve in 100g of water at the following temperatures will be  153 gms, 40 gms, 70gms simultaneously.

<h3>How dissolution of solute is affected by temperature ?</h3>

On increasing temperature the amount of solute for dissolution decreases.

It is independent of the nature of solute.

Hence,

  • KNO₃ at 70degree = 153 gms
  • NaCl at 100 degree = 40 gms
  • NH₄Cl at 90 degree = 70gms
