Answer:
C. minerals within geodes are always framework silicates
Explanation:
This is true going by the facts that, it is only the silicates that can be able to form crystals as obtainable in diamonds etc. Since the minerals in geodes are in the framework of silicates families, they can be able to form euhedral crystals.
Genetic alterations made to an organisms DNA would cause the synthesis of certain proteins that would lead to improvement in that organism’s ability to survive in and through specific components of its environment.
In the context of agriculture, potential benefits of genetic engineering include allowing agricultural organisms to thrive in any environment they were to be grown in, and to fight and persist against biological threats, such as a harmful bacteria.
Overall, potential benefits of genetic engineering in agriculture can be summarized improving the agricultural industry: higher productivity, quality, and efficiency of the crops.
Answer:
The molecular formula of the metal oxide is CuO
Explanation:
Molar mass 79.545 g/m belongs to CuO
This is the reaction:
2Cu(s) + O₂(g) → 2CuO (s)
2 mol of Cu produce 2 mol of CuO
Molar mass Cu = 63.5 g/m
Mass / Molar mass = 1.56 g / 63.5 g/m →0.0245 m
0.0245 mol of Cu produce 0.0245 mole of CuO
Molar mass CuO = 79.545 g/m
Mol . Molar mass = mass
0.0245 m . 79.545 g/m = 1.95 g
Answer:
Ba
Explanation:
The trend for atomic radius is that it increases as you go down and decreases as you go right.
