A dissociation reaction occurs.lets say pcl5=pcl3+cl2
Answer:
12500
Explanation:
In the given question, we are told that when entering large numbers in the answer box, we should not use commas. For example, we should enter 1276400 for the number 1,276,400 instead of writing 1,276,400. Therefore, we should answer the following question by typing the numeric answer into the answer box. What is the sum of 9260 and 3240?
9260 + 3240 = 12500
To express the answer numerically to at least three significant figures, we need to make sure there is minimum of three significant figures (such as 1 2 3 etc) in the answer.
Thus, the answer is 12500 to at least three significant figures
The Ph of a solution with (H3O+) = 5.9 x10 ^-3M is calculated as below
Ph= - Log (H3O+) concentration
that is Ph= -Log ( 5.9 x10^-3) = 2.2
the solution is acidic since the Ph is less than 7
She should add either the 3rd or fourth statement
Answer:
Weathering and erosion
Explanation:
Weathering can be explained as the breaking down of rocks/minerals on the surface of the Earth as a result of contact with biological organism, water, air and other factors
. There are 3 common types of weathering which are;
1) physical weathering
2) biological weathering
3) chemical weathering
Erosion can be regarded as a geological process, whereby earthen material are been transported away by natural forces, these forces could be wind as well as water.
Therefore, as you were climbing a a mountain, you noticed that rocks were crumbling below your feet and moving down the mountain. What is observed are weathering and erosion processes.
After the weakening and broken up of the rock by weathering then erosion transport the bit of the rock down the mountain as you are climbing, which means the "weathering process" breakdown and the "erosion process" involves the transport or movement of the bit of the rocks
