D.
Q= m·ΔT·C(specific heat)= n·M·ΔT·C=10,5mol·27 g/mol· 194,5(225-30,5)·0,9=49600J=49,6kJ.
Answer:
C because both are way too big to pass through the filter
Explanation:
Based on the given scenario above, the correct answer would be option B. Potential energy is a stored energy which is affected by its position, therefore, t<span>he ball at the top of the 5 foot hill has the least potential energy. Hope this answers your question. Have a great day!</span>
Answer:
B. Food can be produced in larger amounts for more people to eat.
Explanation:
Commercial farming mechanizes operations controls diseases and pests, enabling farms to produce more
Answer:
Increasing the temperature increases reaction rates because of the disproportionately large increase in the number of high energy collisions. It is only these collisions (possessing at least the activation energy for the reaction) which result in a reaction
Explanation:
When we increase the temperature of one of the reactants in a chemical reaction, this increases the particles kinetic energy, making them move much faster than they were before. This also increases the chance of a more successful collision and the rate of reaction.
