Answer:
About 0.652
Explanation:
Because the reaction is balanced, we can go straight to the next step. The molar mass of potassium is about 39.098, while the molar mass of hydrogen gas is 2 and the molar mass of water is 18. Therefore, 25.5g of potassium would be about 0.652 moles, and 220 grams of water would be about 12.222 moles, making potassium the limiting reactant. Since there is a single unit of each compound on both sides of the equation, there would be an equal amount of moles of potassium and hydrogen, and therefore about 0.652 moles of hydrogen gas would be produced. Hope this helps!
Answer:
Your question seems to me that it is somewhat poorly written, but it could help you by telling you that by increasing the collision of the individuals, the friction between them increases, therefore increasing the release of energy in the form of heat and thus increasing the temperature.
Therefore, the hypothesis raised would be correct.
Explanation:
If the shock is perfectly inelastic (plastic), the kinetic energy is not conserved and, as a consequence, the colliding bodies can undergo deformations and increase in temperature.
Well, with asexual reproduction you are actually making a genetic copy or the original organism, almost like a clone -- their is no genetic difference between the org organism and its "offspring."
With sexual reproduction the goal is to is to create 4 sex cell either sperm or egg cells. When cells split in sexual reproduction it enables for the off spring to have a great range of genetic diversity. The offspring will be a completly unique not like the mother or father but sharing traits for both. The main benefit of sexual reproduction is genetic diversity.
Because pure silicon is a perfect semiconductor.
For room temperature, it rarely conducts, you can search for the threshold temperature, the characteristic equation is fairly complicated.
The number that will be multiplied by 588 to get one's weight in Newtons is 2.5 considering that the mass of the individual is 60kg.
<h3>How to calculate weight?</h3>
Weight is the force on an object due to the gravitational attraction between it and the Earth (or whatever astronomical object it is primarily influenced by).
The weight of an object can be calculated by multiplying the mass of the object by acceleration due to gravity of the location.
According to this question, we would consider an individual with a mass of 60kg. The acceleration due to gravity on Jupiter is 24.5 m/s².
Weight = 60kg × 24.5 m/s² = 1470N
This means that the number to be multiplied by 588 to get weight of 1470N is 2.5.
