Answer:

6.75 sym.

Explanation:

Boyle's Law:  The pressure of a gas in an enclosed container with a flexible volume is inversely proportional to the volume occupied by the gas.

Empirically => P ∝ 1/V => P = k(1/V) => k = P·V

For any conditions of Pressure & Volume, Pressure x Volume is a constant.

Therefore, k₁ = k₂ => P₁V₁ = P₂V₂ => V₂ =  P₁V₁ / V₂

=> V₂ = (3atm)(0.450L)/(0.200L) = 6.75 atm.

Alkali Metals:a. What is the group number? ______b. Are these metals reactive? ______c. Do these metals occur freely in nature?
slega [8]
<h2>Answer:</h2>

a) Group 1

b) Yes, they are very reactive

c) They do not occur freely in nature

e) Soft

f) Francium and Caesium

g) They react explosively to produce hydrogen gas

<h2>Explanation:</h2>

Alkali metals are metals that belongs to Group 1. They are known to be very reactive due to its tendency to donate their lone electron to other element to attain their octet configuration.

Due to their reactive nature, they do not occur freely in nature unless when combined with other elements.

These group1 metals are known to be soft metals due to their low ionization energy. The two most reactive element in the group are Francium and caesium since reactivity of elements increases from top to bottom of the periodic table.

When these metals are exposed to water, they react explosively to produce hydrogen gas.

What is the relationship
Zielflug [23.3K]

Answer:

The stomach, gallbladder, and pancreas work together as a team to perform the majority of the digestion of food. Food entering the stomach from the esophagus has been minimally processed — it has been physically digested by chewing and moistened by saliva, but is chemically almost identical to unchewed food

Richard and Brooke's teacher tells them to place 30 marbles in an 8-inch
Fynjy0 [20]

Answer:

The correct answer is - They gently shake the pan causing the marbles to move back and forth.

Explanation:

When water is heated the molecules present in its liquid state start to move and vibrate faster and allows the water to expand and increase in volume. If the heat is continuously applied to the water its molecules move even faster and escape in the form of molecules of vapor to the atmosphere.

To exhibit this phenomenon by the marble and pan, Richard and Brooke should gently shake the pan causing the marbles to move back and forth which shows faster vibration and movement of molecules.

Why is 1/t used as a measure of rate of reaction?​
Tpy6a [65]

Answer:

1/t means that the order of reaction is a first order. Meaning that the rate of reaction is directly proportional to reactant concentration. Scientists work with the standard units, therefore 1/t is 1 divide by 1 second.
