Answer:
Explanation:
Hello,
In this case, since the work done at constant pressure as in isobaric process is computed by:
Thus, given the pressure, initial volume and work, the final volume is:
Whereas the pressure must be expressed in Pa as the work is given in J (Pa*m³):
And the volumes in m³:
Thus, the final volume turns out:
Best regards.
A. all magnets have two poles
The formula you need is: heat= specific heat x mass x ΔT
specific heat= 0.46 j/g-C
mass= 100.0 grams
ΔT= 40.2 - 15.0= 25.2C
heat= (0.46) x (100.0) x (25.2)= 1159.2 joules or 1200 joules (rounded off)
Answer:
solution concentration
Explanation:
Among the options given in the above question, solution concentration will affect the rate of a chemical reaction. This is because an increase in reagent concentration speeds up the reaction because there will be a greater number of reagent particles per unit volume, increasing the likelihood of effective collisions between them.
In addition to concentration, the factors that can influence the rate of a chemical reaction are temperature, catalyst, pressure and contact surface.
Answer:
6.48
Explanation:
GeH4 + 3 GeF4 > 4 GeF3H
3 moles of GeF4 react to form 4 moles of GeF4
Therefore, (8 x 3/4)/0.926
= 6.48 moles
