Na₂S₂O₃(aq) + 2HCl(aq) → 2NaCl(aq) + H₂O(l) + SO₂(g) + S(s). A light yellow precipitate develops as the process continues.
<h3>What does the chemistry term "equation" mean?</h3>
Reaction equation are symbolic depictions of chemical reactions where the reactants and products are stated in relation to the following chemical formulae.
<h3>Equation and response are what?</h3>
What is an equations and a chemical reaction? In a chemical change, bonds between molecules of the reagent are destroyed and new bonds between molecules of the product are established to create a new substance. A chemical formula is nothing more than a statement of fact that represents how reactants generate products.

Answer:
Element Helium have<u> 2 energy levels. </u>
Explanation:
<u>HELIUM -</u> With the symbol He and the atomic number 2, helium is a chemical element. It is a colorless , odorless, tasteless, non-toxic, inert, monatomic gas that is the first in the periodic table in the noble gas group. Of all the elements, its boiling point is the lowest.
At about 24 % of the total elemental mass, which is more than 12 times the mass of all the heavier elements combined, it is present. In both the Sun and Jupiter, its abundance is identical to this. This is due to helium-4's very high nuclear binding energy (per nucleon) with respect to the next three elements following helium.
<u>Hence , the answer is 2 energy levels in Helium atom.</u>
Answer:
Explanation:
Hello there!
In this case, according to the given information, it will be possible for us to use the Dalton's law, in order to solve this problem. However, we first need to calculate the mole fraction of oxygen by firstly calculating the moles of each gas:
Next, we calculate such mole fraction as follows:
Then, given the following equation:
So we solve for the total pressure as follows:
Regards!
Use the equation P=VI.
P=power (in this case 10 kilowatts or 10000 watts)
V=voltage (in this case unknown)
I=current (in this case 15.8 amps)
rewrite the equation to be V=P/I
V=(10000 watts)/(15.8 amps)
V=632.9 volts
(I think the equation requires the units for power to be watts so you need to convert kilowatts into watts)
Answer:
Boiling/melting point
Explanation:
Some elements can’t handle the heat nor the cold, so they separate like oil & water.
