In chemistry, a solution is a homogeneous mixture composed of two or more substances. In such a mixture, a solute is a substance dissolved in another substance, known as a solvent.
Each atom will be attracted to both nuclei if the two atoms get close then the nuclei will repel each other
Answer:
a mutation is a change in a DNA sequence
Explanation:
mutations can result from DNA copying mistakes made during cell division
Answer:
Described down below.
Explanation:
Hello,
- Boyle's law: correlation between pressure and volume (assuming temperature and amount of gas remain constant). One common use of Boyle’s law is to predict the new volume of a gas when the pressure is changed (at constant temperature), or vice versa
- Charles' law: correlation between temperature and volume (assuming pressure and amount of gas remain constant). It is used to prove that the absolute 0 unattainable (T=0K).
- Avogadro's law: correlation between amount of gas and volume (assuming temperature and pressure p remain constant). As an example, since we can blow up a basketball, we are adding more gas molecules into it. The more gaseous molecules, the greater the volume.
- Dalton's law: correlation that states that for a mixture of gases in a container, the total pressure exerted is the addition among each pressure that each gas would exert if it were alone. It is useful to analyze the effects of which partial pressure might have on scuba divers. While the total gas pressure increases as a diver increases their descent, the partial pressure of each gas involved increases as well which might cause harm to the diver’s body if proper actions are not carried out.
- Gay-Lussac's law: it states that when the temperature of a sample of gas in a rigid container is increased, the pressure of the gas increases as well. An interesting example is shown when gun pin strikes, because it ignites the gun powder and this increases the temperature which in turn increases the pressure and bullet is fired from the gun.
Best regards.
