Answer:
The correct answers are : A neutron has no charge; Neutrons travel around the nucleus of an atom.
Explanation:
The neutrons correspond to subatomic particles present in the nucleus of the atoms, together with the protons. Neutrons do not have an electric charge and have similar mass to protons. The difference in neutrons between atoms of the same element is called an isotope (they differ in mass numbers from one another, for example Hydrogen and Deuterium).
What's happening is the Mento is causing the carbonation in the bottle to release nearly all at once, causing the pressure in the bottle to increase drastically. This pressure causes the Coke to shoot out of the top, or if there's no hole the pressure makes the top shoot off or something to that effect.
Personally I like to drill holes in the top and use a little bit of wire to drop the Mento in. Then it looks really spectacular :D
Answer:
1250000
Explanation:
Specific heat is mass times specific heat capacity times change in temperature to get chance in temperature minus the old temperature from the new temperature then complete equation hence 25g×1000j×(60-10)
25g×1000j×50
=1250000g/j/degree Celsius
The final volume of the nitrogen sample would be 790 mL
<h3>Charle's Law</h3>
According to Charles, at constant pressure, the volume of a gas is directly proportional to its temperature.
Mathematically: v1/t1 = v2/t2, where v1 and v2 = initial and final volume, and t1 and t2 = initial and final temperature.
In this case, t1 = 37 °C or 310 K, t2 = 77 °C or 350 K, v1 = 700 mL
Thus: v2 = v1 x t2/t1 = 700 x 350/310 = 790 mL

Chemical equilibrium is a condition where the rate of product made is same as the rate of reactant made. Since the reaction to the left is same as the reaction to the right, so the amount of reactant and product will not be changed (doesn't mean that the amount is same, it just won't increase or decrease).
It's called equilibrium since there will be no change in their amount.
