A. Creep
Explanation:
Creep is usually defined as a mass movement process where the rock and other particles are forced to move slowly downward along a slope that is mostly covered with softer sediments and broken rock fragments. It results in the tilting of trees, poles, and gravestones.
The above ionic compound is called gallium sulphate
A reaction vessel that is completely sealed and the Earth would be my answers. This is because the matter inside of these systems is not exchanged anywhere but inside itself. (the glass flask could count, but the not insulated thing might be why it doesn’t count)
Answer:
Explanation:
Here, we want to write the chemical reaction
step 1:
we start by writing the reaction between iron and oxygen
We have this as:

step 2:
Now, we want to predict the product as follows:

step 3:
We proceed to balance the chemical reaction as follows by ensuring that the number of elements moles on the reactant side is equal to the number of moles of the elements on the products side as follows:
Answer:
Al2O3
Explanation:
Al2O3 has an ionic bond because the bonds between them are very strong
