Injecting salt crystals over the ocean to grow cloud droplets has been proposed in efforts to make the clouds brighter thereby affecting the radiation budget. The light of the sun shines on Earth, some of that light is reflected by the clouds back to space and some of the light reaches the earth and warms our planet. The earth and the hot oceans emit infrared radiation (IR), which we feel as heat. That IR "light"; returns to space through the atmosphere. Most are trapped by greenhouse gases, which keep the earth warm. Soon after, the IR radiation returns to space. Scientists call this "energy budget of the Earth" this cycle of incoming and outgoing energy.
Answer is:
It is likely soluble in water.
It will likely light up a bulb in a conductivity apparatus (CaO(l)).
It will likely have a high melting point.
1) Calcium oxide (CaO) has ionic bonds between calcium cations (Ca²⁺) and oxygen anions (O²⁻). It reacts with water and form calcium hydroxide:
CaO(s) + H₂O(l) → Ca(OH)₂(aq).
2) Ionic solid calcium oxide dissolved in water conduct electricty due to the dissociation Ca(OH)₂(aq) → Ca²⁺(aq) + 2OH⁻(aq).
3) Because it has strong ionic bonds, it has high melting point (around 2600°C).
Answer:
The temperature at which a substance changes from the liq- uid state to the solid state is called the freezing point. The freez- ing point of the liquid state of a substance is the same temperature as the melting point of the solid state. For example, solid water melts at 0°C and liquid water freezes at 0°C.
Explanation:
Answer:
68.3 kilo Pascal is the pressure in the container.
Explanation:
To calculate the new pressure , we use the equation given by Boyle's law. This law states that pressure is inversely proportional to the volume of the gas at constant temperature.
The equation given by this law is:
where,
are initial pressure and volume.
are final pressure and volume.
We are given:
Putting values in above equation, we get:
68.3 kilo Pascal is the pressure in the container.
