Answer:
100 celsuis
Explanation:
because it melts faster at a 100 degrees Celsius.
1) protons have a positive charge
2) electrons have a negative charge
3) neutrons have a neutral charge
Answer: The new pressure of the gas in Pa is 388462
Explanation:
Combined gas law is the combination of Boyle's law, Charles's law and Gay-Lussac's law.
The combined gas equation is,
where,
= initial pressure of gas at STP =
= final pressure of gas = ?
= initial volume of gas = 700.0 ml
= final volume of gas = 200.0 ml
= initial temperature of gas = 273 K
= final temperature of gas =
Now put all the given values in the above equation, we get:
The new pressure of the gas in Pa is 388462
Light is both a wave and a particle. Good luck!
Answer:
24.5 moles of mercury are produced
Explanation:
The descomposition of mercury(II) oxide, occurs as follows:
2HgO → 2Hg + O₂
<em>Where 2 moles of HgO produce 2 moles of Hg</em>
<em />
In other words, the ratio of descomposition of HgO/Hg is 2/2 = 1:1
That means, if 24.5 moles of mercury(II) oxide descompose:
<h3>24.5 moles of mercury are produced</h3>
