Answer:
the answer is tetahedal and the next one is trigonal pyramidal
Explanation:
Answer:
The correct option is D
Explanation:
The major raw material used in making cement clinker is limestone. This limestone is usually mixed and heated with clay and can sometimes be mixed, in addition to the clay, with fly ash, black ash, bauxite, iron ore and gypsum. <u>However, the product cement clinker contains different calcium silicates and/or aluminates such as Ca₃SiO₅, Ca₃Al₂O₆, Ca₂(Al,Fe)₂O₅ and Ca₂SiO₄</u>. Thus, the correct option is D.
C. It increases and the pH stays constant.
What is diffusion?
The diffusion of substances within a solution tends to move those substances <u>down</u> their <u>concentration</u> gradient.
Aim of diffusion:
The movement of molecules along a concentration gradient is known as diffusion. It is a significant process that all living things go through. Diffusion facilitates the flow of materials into and out of cells. Until the concentration is the same everywhere, the molecules travel from a location of higher concentration to a region of lower concentration.
Diffusion occurs in gases and liquids because random molecular movement is possible.
Types of diffusion:
Simple diffusion and facilitated diffusion are the two primary categories of diffusion.
- Simple diffusion: An action where the substance passes across a semipermeable barrier or solution without the aid of transport proteins. For instance, bacteria use simple diffusion to transport minute nutrients, water, and oxygen into the cytoplasm.
- Facilitated diffusion: It is the passive transfer of molecules from the area of higher concentration to the area of lower concentration across the cell membrane using a carrier molecule.
The main aim of diffusion is to arrive at an equilibrium state. When the amount of the particles is uniformly distributed or constant throughout a solution, it is said to be in equilibrium.

Answer:
A. Hydrogen cans oxygen are reactants
Explanation:
Oxygen has a charge of -2. Hydrogen has a charge of +1. So it takes two hydrogens to balange the one oxygen hence the H20. So the reaction is balanced, and H20 is indeed made up of 1 oxygen and 2 hydrogen atoms. The equation 2 hydrogen + 1 oxygen (<---reactants) = Water (<--product) So hence Hydrogen cans oxygen is not a true statement. If cans is a misspelling then C would be your answer.
Hope that helped
