Answer:
42
Explanation:
Divide the distance by the time.
Answer:
30 °C
Explanation:
When you pour water from one glass to the other, the heat energy will flow from the hot water to the cold.
You have equal masses of water in each glass. The hot water should cool down as much as the cold water warms up.
The final temperature should be halfway between the starting temperatures in each glass.
(10 °C + 50°C)/2 = 60 °C/2 = 30°C
The temperature of the full glass of water should be 30 °C.
Your answer is
Ca(OH)₂ + 2HNO₃ → Ca(NO₃)₂ + 2H₂O I hope it is at least :P
Answer:
the correct choice would be: 4. Reaction rates are not related to spontaneity.
Explanation:
The speed of reaction is independent of spontaneity, since it depends on other factors such as the amount of reagent.
The amount of reagent is one of the variables that most influences the speed of reaction, the greater the amount of reagent, the faster the reaction will be and thus the speed will be increased.
The surface metabolism model evokes mineral
catalysts. Surface metabolism model dissolved gases in contact with
minerals lining the walls of the deep-sea hydrothermal vents and formed more
complex, organic molecules while Prebiotic soup model is molecules in
atmosphere or from meteorites condensed in the ocean which led to the formation
of more complex molecules.
