Geiger counter, hope this helps food luck
The electron cloud model describes electrons as the most likely found around the nucleus of an atom. It is also found that electrons could seemingly be everywhere at one time. Albert Einstein, Max Planck and Niels Bohr had done a research and have concluded that electrons transmit energy and that its properties are also linked to light and energy.
Answer:
800 g
Explanation:
We can express the decay of I-37 using the formula:
- Final Mass = Initial Mass *
We <u>input the data</u>:
- 25 g = Initial Mass *
And <u>solve for Initial Mass</u>:
- 25 g = Initial Mass *
- 25 g = Initial Mass * 0.03125
Meaning that out 800 grams of I-37, only 25 will remain after 40.35 days.
Answer:
127.15 g of ZnCl₂
Solution:
The balance chemical equation is as follow,
<span> Zn + 2 HCl </span>→ ZnCl₂ + H₂
According to equation,
65.38 g (1 mole) of Zn produced = 136.28 g (1 mole) of ZnCl₂
So,
61.0 g of Zn will produce = X g of ZnCl₂
Solving for X,
X = (61.0 g × 136.28 g) ÷ 65.38 g
X = 127.15 g of ZnCl₂
Answer:
Explanation:
Hello!
In this case, for the undergoing chemical reaction at equilibrium:
Which means that pressure-based equilibrium constant is computed via the following equilibrium expression:
Thus, by plugging in the given pressures at equilibrium, the required Kp turns out:
Best regards!
