Answer: The coefficient is 3.645
The exponent is 1
There are 4 significant digits
The rightmost significant figure is 5
Explanation:
Scientific notation is defined as the representation of expressing the numbers that are too big or too small and are represented in the decimal form with one digit before the decimal point times 10 raise to the power.
For example : 5000 is written as 
According to avogadro's law, 1 mole of every gas contains avogadro's number
of particles, occupy 22.4 L at STP and weighs equal to its molecular mass.
131.29 g of Xe occupy = 22.4 L at STP.
Thus 213.62 g of
occupy =
at STP.
Scientific notation = 
The coefficient is 3.645
The exponent is 1
There are 4 significant digits
The rightmost significant figure is 5
Answer : The concentration of
is, 0.12 M
Explanation :
Using Henry's law :

where,
= concentration of
= ?
= partial pressure of
= 4.5 atm
= Henry's law constant = 
Now put all the given values in the above formula, we get:


Thus, the concentration of
is, 0.12 M
Answer:
The answer is Conduction
Explanation:
Conduction is the process of heat being transferred between objects through direct contact, and it's the most common type of heat transfer.
1 milliliters in one milligram.
Answer:
The correct answers are:
• Softer, porous, or more permeable rocks weather faster than harder rocks.
• Rocks in warmer climates weather faster than rocks in colder climates.
• The more water present, the faster the rate of weathering.
Explanation:
Weathering is the process through which the surface minerals of rock are broken down and loosened. This occurs through the action of extreme temperatures, rainwater and biological activity.
