What is the net charge?

1 answer:

6 0

To find the net charge you take the number of protons and subtract the number of electrons, and the answer will be your charge.

This atom has 11 electrons AND 11 protons
11 - 11 = 0 net charge

What would happen if a bird was a vulture riding on a zebra's back? How would it affect the relationship?

OLEGan [10]

The zebra could be "hen pecked" if the vulture was a hen bird. On the other hand, the two might get along ok. In UK, it they 'd make a useful combination helping each other to cross increasingly dangerous roads (joke).

A radioactive isotope has a half-life of 5,000 years. A rock originally contained 16 grams of radioactive isotope, and now conta

mixas84 [53]

Answer:

10,000 years

Explanation:

Given that,

Half life of the radioactive isotope, $t_{\frac{1}{2}}$ = 5000 years

Initial composition, $N_0$ = 16 grams

Final composition, $N$ = 4 grams

We know that,

$N=N_0\times (\dfrac{1}{2})^\frac{t}{t_\frac{1}{2}}}\\\\4=16(0.5)^\frac{t}{5000}}\\\\\dfrac{4}{16}=(0.5)^{\frac{t}{5000}}\\\\0.25=(0.5)^\frac{t}{5000}\\\\0.5^2=(0.5)^\frac{t}{5000}\\\\2=\dfrac{t}{5000}\\\\t=2\times 5000\\\\t=10000\ yrs$

Therefore, the age of the rock is 10,000 years.
