A motor cyclist starts from rest and reaches a speed of 6m/s after travelling with uniform acceleration for 3s. What is his acce
choli [55]

Answer:

2m/s²

Explanation:

When an object starts or at its state of rest it has an Initial speed U = 0

Final speed = 6m/s

total time taken for the acceleration = 3s

Acceleration =?

Acceleration is the change in velocity (speed) with time

OR

Time rate of change of velocity

Acceleration = <u>Change in Speed(velocity)</u>

Time taken

Hence,

Acceleration = <u> </u><u> </u><u>V - </u><u>U</u><u> </u><u> </u>

t

a = <u>6</u><u> </u><u>-</u><u> </u><u>0</u>

3

a = <u>6</u><u> </u><u> </u>

3

a = 2m/s²

What exacerbates the heat waves?
KIM [24]

Answer:

A heatwave occurs when a system of high atmospheric pressure moves into an area and lasts two or more days.

Explanation:

In such a high-pressure system, air from upper levels of our atmosphere is pulled toward the ground, where it becomes compressed and increases in temperature.

Balance this redox reaction occurring in acidic media:
Lelu [443]
Add 7 water atom to the right hand side to adjust the quantity of oxygen. Increase Cr(+3) by two to adjust the quantity of Cr. Duplicate Cl-by two to adjust the quantity of chlorine molecules. 
Cr2O7[2-](aq) +2 Cl[-](aq) < - >2 Cr[3+] (aq) + Cl2(g)+7H2O 
Presently adjust that charges. 
you have - 4 charges on the left hand side, while +18 charges on the right hand side, there for include 14H+ the left hand side to adjust the charges 
Cr2O7[2-](aq) +2 Cl[-](aq)+14H+ < - >2 Cr[3+] (aq) + Cl2(g)+7H2O 
take note of that the oxidation number of hydrogen in water is +1

Given that Δ H ∘ f [ Br ( g ) ] = 111.9 kJ ⋅ mol − 1 Δ H ∘ f [ C ( g ) ] = 716.7 kJ ⋅ mol − 1 Δ H ∘ f [ CBr 4 ( g ) ] = 29.4 kJ
JulsSmile [24]

Answer:

283.725 kJ ⋅ mol − 1

Explanation:

C(s) + 2Br2(g) ⇒ CBr4(g) , Δ H ∘ = 29.4 kJ ⋅ mol − 1

\frac{1}{2}Br2(g) ⇒ Br(g) ,  Δ H ∘ = 111.9 kJ ⋅ mol − 1

C(s) ⇒ C(g) ,  Δ H ∘ = 716.7 kJ ⋅ mol − 1

4*eqn(2) + eqn(3) ⇒ 2Br2(g) + C(s) ⇒ 4 Br(g) + C(g) , Δ H ∘ = 1164.3 kJ ⋅ mol − 1

eqn(1) - eqn(4) ⇒ 4 Br(g) + C(g) ⇒ CBr4(g) , Δ H ∘ = -1134.9 kJ ⋅ mol − 1

so,

   average bond enthalpy is \frac{1134.9}{4} = 283.725 kJ ⋅ mol − 1
