Chemical Weathering is the process of decomposition, erosion and spoilage of Solid materials like Building Material, Rocks e.t.c.
This decomposition takes place due to chemical reaction. The chemical present in Air along with water undergo chemical decomposition of Solid materials.
So, first requirement for this process is water, which is present in air called precipitation. Secondly, temperature also play important role.
Result:
<span>The amount of chemical weathering will increase if Temperature and Precipitation Increases.</span>
It's 9.865 * 10^3 . The first number has to be between 1 and 10, and then multiply the number by ten, so it's 9.865 times 10 to the power of 3.
Answer:
Mass = 47.04 g
Volume = 23.94 L
Solution:
The equation for given reaction is as follow,
BaCO₃ + 2 HNO₃ → Ba(NO₃)₂ + CO₂ + H₂O
According to this equation,
197.34 g (1 mole) BaCO₃ produces = 44 g (1 mole) of CO₂
So,
211 g of BaCO₃ will produce = X g of CO₂
Solving for X,
X = (211 g × 44 g) ÷ 197.34 g
X = 47.04 g of CO₂
As we know,
44 g (1 mole) CO₂ at STP occupies = 22.4 L volume
So,
47.04 g of CO₂ will occupy = X L of Volume
Solving for X,
X = (47.04 g × 22.4 L) ÷ 44 g
X = 23.94 L Volume
Answer: A
Explanation:
One element replaces another in a compound.
What's the problem ? Hardness is not the definition of a metal.
You need to expand your thinking. EVERY element is solid, liquid, and gas, over different ranges of temperature ... including all of the metals. There are only TWO elements that are liquid AT ROOM TEMPERATURE, and mercury is one of them. But on a mild day at the south pole, mercury is solid too.
