The answer is 1) mixing of two gases by diffusion.
Once 2 gases are mixed by diffusion, they cannot be obtained from the mixture of gases. Hence, it is considered to be an irreversible process.
Answer:
This is what they usually do.
Explanation:
Scientists are often people who want to see change occur. ... Today, the role of a scientist is the same. We have the obligation to explore and discover. Scientists use their resources to bring about change, whether it is change in medicine, improvements in the environment, or creating more efficient fuels
<h3>Answer : 2C + 3H2 -> C2H6</h3>
<h3>Step and explanation</h3>
Condition : graphite + hydrogen gas
Chemical formula : C + H2
Reaction formula :
C + H2 -> C2H6
#First, you see the number of atom
•Product
C = 1
H = 2
•Reactant
C = 2
H = 6
<em>#</em><em>N</em><em>o</em><em>t</em><em>e</em><em> </em><em>that</em><em>,</em><em> </em><em>in</em><em> </em><em>a</em><em> </em><em>chemical</em><em> </em><em>reaction</em><em> </em><em>both</em><em> </em><em>number</em><em> </em><em>of</em><em> </em><em>each</em><em> </em><em>atom</em><em> </em><em>in</em><em> </em><em>product</em><em> </em><em>must</em><em> </em><em>be</em><em> </em><em>equal</em><em> </em><em>in</em><em> </em><em>reactant</em><em> </em><em>so</em><em>,</em><em> </em><em>you</em><em> </em><em>think</em><em> </em><em>what</em><em> </em><em>number</em><em> </em><em>you</em><em> </em><em>need</em><em> </em><em>to</em><em> </em><em>put</em><em> </em><em>Infront</em><em> </em><em>of</em><em> </em><em>the</em><em> </em><em>chemical</em><em> </em><em>formula</em><em> </em><em>so</em><em> </em><em>that</em><em> </em><em>the</em><em> </em><em>number</em><em> </em><em>of</em><em> </em><em>atom</em><em> </em><em>equal</em>
2C + 3H2 -> C2H6
#Now check again
•Product
C = 2
H = 6
•Reactant
C = 2
H6
#Now, its equal. The bold one is the balance chemical reaction
<h3>Note (just incase u dont know)</h3>
Reactant -> product (the thing you get after reaction)
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>
