<u>Answer: </u>The amount of heat released is 84 calories.
<u>Explanation:
</u>
The equation used to calculate the amount of heat released or absorbed, we use the equation:
where,
Q = heat gained or released = ? Cal
m = mass of the substance = 10g
c = specific heat of aluminium = 0.21 Cal/g ° C
Putting values in above equation, we get:
Q = -84 Calories
Hence, the amount of heat released is 84 calories.
Answer:
True
Explanation:
Protons and neutrons are found in the atom's nucleus and electrons are in regions outside the nucleus. Protons have a positive charge, electrons have a negative charge, and neutrons have no charge.
Answer:
10 moles of S₈
320 moles O₂
Explanation:
The balanced equation is:
Now we can convert moles of SO₈ (the product) into moles of each reactant, using the <em>stoichiometric coefficients of the balanced reaction</em>:
- 80 mol SO₈ *
= 10 mol S₈
- 80 mol SO₈ *
= 320 mol O₂
In order for 80 moles of SO₈ to be produced, 10 moles of S₈ need to react with 320 moles of O₂.
Answer:
The only one I know is NaC2HO4.
There is Sodium, Carbon, Hydrogen and Oxygen.
1 atom in sodium, 2 atoms in carbon, 1 atom in hydrogen and 4 atoms in oxygen completeting the total of 8 atoms in this element.
I can’t tell what the question is but it would boil faster at Big Bear faster because the boiling point of water is lower at higher altitudes.
