They are in free fall. In a vacuum, gravity causes all objects to fall at the same rate, and since they all are falling together. The astronauts and other objects appear to float when compared with the spacecraft.
this should be it hope it helps Cu2(OH)2CO3
Answer: 1. The solvent in a mixture of gases is generally considered to be the substance in greater amount. 2. The solid dissolved in a solution is known as the solute. 3. Solid solutions are called alloys.
Explanation:
A binary solution is made up of two components ,called as solute and another as solvent.
A solute is defined as the component which is present in smaller proportion. It can be in solid, liquid or gaseous phase. A solvent is defined as the component which is present in larger proportion in a solution. It can be in solid, liquid or gaseous phase.
Usually in liquid solutions , solid acts as solute and liquid acts as solvent. For example: In salt solution, salt is the solute and water is the solvent.
Solid solutions contains solid as solute and solid as solvent. These are called as alloys. For example : In brass, zinc is the solute and copper is the solvent.
Answer:
It reacts with metals to form metal hydroxide and hydrogen gas. it s an chemical property and it decomposes to H2 and O2 is also another chemical property property. because in these reaction H2O has changed to something else hence are called chemical property.
