The reaction represents the law of conservation of mass (a balanced chemical equation :
2NaN₃ → 2Na + 3N₂
<h3>Further explanation
</h3>
Conservation of mass applies to a closed system, where the masses before and after the reaction are the same, so balanced chemical equations show that mass is conserved in chemical reactions.
So we just have to look at the amount of each type of element present in the reactants and products must be the same
1. Hg + O₂ → HgO
not balanced, because element O not equal(2 in left, 1 in right)
2. 2NaN₃ → 2Na + 3N₂
balanced, because element in reactant and product are the same
Na, left = 2, right=2
N, left =2x3=6, right=3x2=6
3. C+O → CO₂
not balanced, because element O not equal(1 in left, 2 in right)
4. CH₄ + O₂ → CO₂ +H₂O
not balanced, because element O and H not equal
The answer would be using proportions 151/x=166/0.532, then you solve for x. The answer would be <span>0.483927711, but then you have to round it and get approximately 0.484 L. Hope this helps! Happy Studying!</span>
Answer:
G. The velocity is not changing because the speed is constant.
Explanation:
The temperature would slowly decrease until the bowl's internal temperature matches the refrigerator's internal temperature.
I hope this is the answer you needed.
Answer:
SF2(aq) → S²⁺(aq) + 2F-(aq)
Explanation:
The sulfur difluoride, SF2, dissolves in water because the differences in electronegativities are considerable (3.98 for Fluorine and 2.58 for S) doing the F-S bond polar. As water is a polar solvent will dissolve the SF2 as follows:
<h3>SF2(aq) → S²⁺(aq) + 2F-(aq)</h3>
<em>As Fluorine has a > electronegativity than S, the Fluorine will be negative and S will be positive. Also, all halogen ions has a charge of -1.</em>
