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

Which of the following displays the correct change in enthalpy and best describes the reaction below? 2CsCl(aq) + Na2SO4(aq) 2Na
Bond [772]
We subtract the enthalpies of the reactants from that of the products:
2\Delta&#10; H(NaCl)+\Delta H(Cs_2 SO_4)-2\Delta H(CsCl)-\Delta H(Na_2 SO_4) \\ &#10;=2(-411)+(-1400) -2(-415)-(-1380) \\ = -12 kJ
Since this is < 0, this is an exothermic reaction.

madam [21]

When sulfur reacts with zinc metal is forms a compound known as zinc sulfide.

<h3>Name of the elements</h3>

The names of the elements that make up the compound will be determined from the atomic mass of the elements.

<h3>Which element has atomic number 30</h3>

The element that atomic number of 30 is zinc and it has oxidation number of +2.

<h3>Which element has atomic number 16</h3>

The element that atomic number of 16 is sulfur and it has oxidation number of -2.

<h3>Chemical reaction between sulfur and zinc metal</h3>

Zn²⁺ + S²⁻  --------> ZnS

Thus, when sulfur reacts with zinc metal is forms a compound known as zinc sulfide.
