Answer:

9000J

Explanation:

Given parameters:

Mass of the jet fighter  = 5kg

Velocity  = 60m/s

Unknown:

Kinetic energy of the jet fighter  = ?

Solution:

The kinetic energy of a body is the energy due to motion of the body.

It is mathematically expressed as;

    K.E  = \frac{1}{2} m v²

m is the mass

v is the velocity

 So;

     K.E  =  \frac{1}{2}  x 5 x 60²  = 9000J

1.00 x 10^6 atoms of gold is equivalent to how many grams?
S_A_V [24]

Answer:

3.27 x 10⁻¹⁶ grams

Explanation:

moles Au = 1.00 x 10⁻⁶ Atoms / 6.02 x 10²³Atoms / mole = 1.66 x 10⁻¹⁸ mole Au

grams Au = 1.66 x 10⁻¹⁸ mole Au x 196.97 grams Au/mole Au

= 3.27 x 10⁻¹⁶ grams Au

How can we increase the rate of collisions between the reactants in this reaction?
Juli2301 [7.4K]

Answer:

According to the collision theory, we can increase the rate of a reaction by increasing the concentration of reactants. We can also increase the rate of a reaction by increasing temperature to safe levels.

In the reaction mentioned in the question, Mg + 2HCl → MgCl2 + H2, if we increase the amount of magnesium or HCl, the reaction will proceed faster. Similarly, if we increase the temperature, then also the reaction rate will increase.
