Not enough food to eat is A: Abiotic
Answer:
Tetrahedral
Trigonal pyramidal
less than 109.5°
Explanation:
If a molecule has a hybridization of sp3 it must have four electron domains which corresponds to a tetrahedral geometry.
Now we were told that the molecule also has one lone pair. It means that one out of the four electron domains is composed of a lone pair. Thus the molecular geometry will be trigonal pyramidal (e.g NH3).
Recall that lone pairs usually decrease the bond angle to a value less than the expected value for that particular electron domain geometry.
The expected bond angle for a tetrahedral geometry is 109.5° but that of the trigonal planar geometry is less than this.
Tollen's test is a test for aldehyde giving a silver mirror in its presence, hence also called silver mirror test. Among the choice, c. pentanal is the aldehyde. Answer is C.
Explanation: cell in the body is enclosed by a cell (Plasma) membrane. The cell membrane separates the material outside the cell, extracellular, from the material inside the cell, intracellular. ... All materials within a cell must have access to the cell membrane (the cell's boundary) for the needed exchange
**Answer**: The answer would be Yes I believe
Answer:
From mud and clay to diamonds and coal, Earth's crust is composed of igneous, metamorphic, and sedimentary rocks. The most abundant rocks in the crust are igneous, which are formed by the cooling of magma. Earth's crust is rich in igneous rocks such as granite and basalt.
