Answer:
K
Explanation:
The picture that demonstrates a state of matter without a fixed shape or fixed volume is picture K.
Gases are one of the three states of matter without a fixed shape and volume. They simply take up the shape of their containers and are free to move all about.
- Liquids and solids are known to have fixed shape and volume.
- Liquids are know for their ability to flow. Figure L
- Solids are rigid bodies. It is the figure J
0.1m moles of solute particles are present in 1 L of each of the following aqueous solutions.
The number of moles of solute = mass of solute ÷ molar mass of solute, where mass is measured in grams and molar mass (defined as the mass of one mole of a substance in grams) is measured in g/mol
<h3>What is meant by moles of solute?</h3>
Molality is defined as moles of solute per kilogram of solvent. Molality = mass of solvent (in kg) moles of solute = molecular weight of solute × mass of solvent (in kg) mass of solute.

Answer:
The correct answer is
option 1. a relatively high number of collisions between reacting particles are effective.
Explanation:
Activation energy refers to the amount of energy which is required by the reacting substances to take part in chemical reaction. If the activation energy is higher, the molecules moves very fast and reaction does not occur. Chemical reaction occurs when the reactant possess low amount of energy.
Ionic. because MgcI2 is a compound of a metal and a non metal, which seems to form a ionic bonds together
Answer:
Answer D
Explanation:
The Earth's system can be placed into four sub- groupings- : atmosphere, biosphere, lithosphere, and hydrosphere.
