Answer: i think its protons and electrons but it also might just be atoms because protons and electrons make atoms when there are also neutrons
Explanation:
Answer: A bike
A bike is composed of various simple machines. It has a wheel and axle as one component, and it also has screws to hold the various parts together, along with levers and pulleys that are connected to the pedals. So all of these simple machine concepts work together to help transport the rider from point A to point B.
The other answer choices of screw, inclined plane, and lever, are fairly simple machines that don't have many things going on at once compared to a bike.
Pressure has little effect on the solubility of liquids and solids because they are almost incompressible True.
Liquids and solids show little change in solubility with changes in pressure. As expected, gases increase in solubility with increasing pressure. Henry's Law states that the solubility of a gas in a liquid is directly proportional to the pressure of that gas above the surface of the solution.
External pressure has little effect on liquid and solid solubility. In contrast, the solubility of a gas increases as the partial pressure of the gas above the solution increases.
Solubility is a measure of the concentration of dissolved gas particles in a liquid and is a function of gas pressure. Increasing the gas pressure increases the number of collisions and increases the solubility, and decreasing the pressure decreases the solubility.

Answer:
The relative conjugate acids and bases are listed below:
CH3NH2 → CH3NH3+
H2SO3→ HSO3-
NH3→ NH4+
Explanation:
In a Brønsted-Lowry acid-base reaction, a conjugate acid is the species resulting from a base accepting a proton; likewise, a conjugate base is the species formed after an acid has donated a hydrogen atom (proton).
To this end:
- HSO3- is the conjugate acid of H2SO3 i.e sulfuric acid has lost a proton (H+)
- NH4+ is the conjugate acid of NH3 i.e the base ammonia has gained a proton (H+)
- OH- is the conjugate base of H20
- CH3NH3+ is the conjugate base of the base CH3NH2 methylamine
