Answer:
The air pressure is 9.8 *10^4 pa
The water will rise to a height of 10.0 meter
Explanation:
Step 1: Data given
As a storm from moves in, you notice that a column of mercury in a barometer rises to 736 mm.
Step 2: Calculate the air pressure
The Pressure against the mercury column = h*d*g = 0.736 * 13593 * 9.81 = 9.8 * 10^4 Pa
Step 3: Calculate the height of the water
Let the Pressure the water column for same pressure is h meter : -
9.8 * 10^4 = h*d*g
=>9.8*10^4 = h*1000*9.81
=>h = 10.0 meter
The water will rise to a height of 10.0 meter
Explanation:
A physical change is change that alters the physical properties of matter especially its form and state.
In many cases, the change is easily reversible.
Examples are change of state such as boiling, melting, freezing, condensation, sublimation e.t.c
A chemical change is one in which a new kind of matter is formed. It is always accompanied by energy changes.
Examples are combustion, rusting , precipitation, milk souring.
- Chemical changes are irreversible
- Physical changes do not lead to the formation of new kinds of matter.
- Most physical changes requires little energy.

Answer:
Argon is an element on the periodic table. It is a member of the noble gasses, meaning that it is a monoatomic pure gas. In other words, argon gas particles are simply pure single atoms of argon. ... Finally, water is a polyatomic molecule H2O composed of two atoms of hydrogen and one atom of oxygen.
Explanation:
Answer:
D. They react readily with oxygen in the air
