Calculate the kinetic energy of a 150 g baseball moving at a speed of 40. m/s (89 mph).

LUCKY_DIMON [66]

Kinetic Energy= 0.5 times velocity squared times mass
So KE= 0.5times 150 times 40 squared

(Use a calculator)
And don't forget units

In the reaction, 3Cu + 2Al3+ → 3Cu2+ + 2Al, which substance is being oxidized?

Wittaler [7]

In this reaction, Copper is the element being oxidized because it is losing electrons. It starts with a neutral charge (0) and ends up with a 6+ charge. Because its charge is increasing, it is being oxidized (losing electrons).

Write the molecular formula for a compound with the possible elements C, H, N and O that exhibits a molecular ion at M

liberstina [14]

Answer:

$= \mathbf{C_3H_6O}$

Explanation:

From the given information, since the molecular mass of the ion M+ is not given;

Let's assume M+ = 58.0423

So, by applying the 13th rule;

we will need to divide the mass by 13, after dividing it;

The quotient n = no. of carbon; &

The addition of the quotient (n) with the remainder r = no. of hydrogen.

So;

$\dfrac{58}{13}= 4 \ remainder \ 6$

So;

$C_nH_{n+r} = C_4H_{4+6}$

$= C_4H_{10}$

From the given information; we have oxygen present, so since the mass of oxygen = 16, we put oxygen in the molecular formula by removing $CH_4$ . Also, since the mass is an even number then Nitrogen is 0.

So, we have:

$= \mathbf{C_3H_6O}$
