A low pressure system has lower pressure at its center than the areas around it. Winds blow towards the low pressure, and the air rises in the atmosphere where they meet. As the air rises, the water vapor within it condenses, forming clouds and often precipitation.
<u>Explanation</u>:
- Wind flow towards the low pressure and the air rises in the atmosphere. As the air increases, the water vapor within it solidifies, forming clouds and undergo precipitation. Low pressure formed in the center areas.
- The atmospheric circulations of air up and down in a low-pressure area remove a small amount of atmosphere. This usually happens between warm and cold air masses by flowing air which tries to reduce the contrast of temperature.
Mass of Pd = 95.78 g which is close the the variant E) 95.89
Explanation:
To calculate the number of moles of palladium (Pd) we use the following formula:
number of moles = mass / atomic weight
mass = number of moles × atomic weight
mass of Pd = 0.90 × 106.42
mass of Pd = 95.78 g

Answer:
More than 50% of the 100 billion stars in the Milky Way galaxy have at least one planet orbiting.
Explanation:
This is False so this would be your Answer
We can use the reactivity series of metals to solve this.
The reactivity series of metals are (in descending order) :
Potassium, sodium, Lithium, calcium, Magnesium, aluminum, zinc, iron, tin, lead, copper, mercury, silver, platinum, gold.
Since Potassium is the most reactive, the reaction with water should produce extremely violent gas.
Sodium is the next most reactive, so it should produce violent gas.
And Lithium is the least reactive out of the 3 metals, so it should be strong gas formation.
In addition, the gas produced should be hydrogen, since the reaction of metals should water should produce "metal name" hydroxide + hydrogen.
