Answer:
Explanation:
Polar molecules interact with other molecules of similar polarity to form solutions. Non-polar molecules do not interact the same way.
Nuclear power plant because that is a fission reaction and fusion would melt the power plant
Answer:
28.1
Explanation:
Divide the percentage abundances by 100:
92.2% ÷ 100 = 0.922
4.7% ÷ 100 = 0.047
3.1% ÷ 100 = 0.031
multiply them by their corresponding mass number:
0.922×28 = 25.816
0.047×29 = 1.363
0.031×30 = 0.93
add them all together to get your final answer:
25.816 + 1.363 + 0.93 = 28.109
to one decimal place:
28.1

Answer:
2.99 atm
2279.43 torr
44.07 psi
Explanation:
Torr, atms and psi all units are units of pressure.
Conversion from KPa to atm:
1 KPa is equal to 0.00987 atm. To convert from KPa to atm we will multiply the given value with 0.00987 atm.
303.9 KPa × 0.00987 atm / 1 KPa
2.99 atm
Conversion from KPa to torr:
1 KPa is equal to the 7.5006 torr. To convert from KPa to torr we will multiply the KPa value by 7.5006.
303.9 KPa × 7.5006 torr/ 1 KPa
2279.43 torr
Conversion from KPa to psi:
psi is pound per square inch. 1 KPa is equal to the 0.1450 psi. To convert from KPa to psi we will multiply the KPa value by 0.1450 psi.
303.9 KPa × 0.1450 psi / 1 KPa
44.07 psi
Answer:
Why are redox reactions used in batteries? The attraction between charged ions releases energy. The movement of electrons creates an electric current. The reactions are extremely exothermic, producing an electric current.
Explanation:
Why are redox reactions used in batteries?
The attraction between charged ions releases energy.
The movement of electrons creates an electric current.
The reactions are extremely exothermic, producing an electric current.
The reactions are extremely endothermic, inducing the movement of electrons.
