Answer:
Explanation:
Earthquakes are normally caused by underground rock breaking along a fault line. The seismic waves that cause the earth to shake are caused by this sudden release of energy. The plates or blocks of rock begin to move during and after the earthquake, and they continue to move until they become trapped again. As fluid near the center heats up, convection currents develop within the Earth's mantle. Particles pass more quickly as the core heats the bottom layer of mantle material, lowering its density and allowing it to rise. The convection current is started by the growing material.

<em>A student is doing experiments with CO2(g). Originally, a sample of gas is in a rigid container at 299K and 0.70 atm. The student increases the temperature of the CO2(g) in the container to 425K.</em>
<em>Calculate the pressure of the CO₂ (g) in the container at 425 K.</em>
<em />
<em />
Gay Lussac's Law
When the volume is not changed, the gas pressure is proportional to its absolute temperature
P₁=0.7 atm
T₁=299 K
T₂=425 K

Answer:
Molarity.
Explanation:
- The molarity (M) of a solution is defined as the no. of moles of solute that dissolved in 1.0 liter of the solution.
M = (mass / molar mass) of the solute (1000 / volume of the solution).
<em>So, the best measurement of concentration for describing the concentration of a solid solute dissolved in one liter of a liquid solution is Molarity.</em>
Answer: Come Onshore
Explanation:
Sea waves are harmless when present at Sea. However, it becomes DESTRUCTIVE as it travels to the land surface.
Its effects include the sweeping off (erosion) of features, BENEFICIAL soil organisms and the transport of sand and sediment along coastal areas which might include farms, residential houses etc.
Thus, the effects of Sea waves ONSHORE affects the following: agricultural activities
Domestic activities
Environmental balance etc.
Answer:
MgCl2 > C4H9OH > CH4 > C3H8.
Explanation:
Alkanes do not form hydrogen bonds and are insoluble in polar solvents e.g water. The hydrogen bonds between water molecules are move away from an alkane molecule and this worsens as their Carbon chain / molecular weight increases.
MgCl2 is soluble in water. Water essentially breaks down the ionic crystal lattice and the resulting solution is slightly basic.
Alcohols are generally soluble in water and this is because of the -OH group and its ability to form hydrogen bonds with water molecules. As applied to alkanes, as the carbon chain in the alkyl group increases, the solubility decreases.
From the most soluble to the least soluble,
MgCl2 > C4H9OH > CH4 > C3H8.
