Answer:
Contemporary light microscopes are able to magnify objects up to about a thousand times. Since most cells are between 1 and 100 μm in diameter, they can be observed by light microscopy, as can some of the larger subcellular organelles, such as nuclei, chloroplasts, and mitochondria.
Answer:
Chemistry, the science that deals with the properties, composition, and structure of substances (defined as elements and compounds), the transformations they undergo, and the energy that is released or absorbed during these processes
First you want to convert the Celsius to Kelvin, so 10C will be 283.15K, and 100C will be 373.15K.
Then, we have to look at the PVnT relationships to determine what to do. Since T increases, that must mean V increases. And since pressure increases, V will increase from that too. I believe it can be assumed # of particles then stay constant.
1) The first ratio is your given value
20mL
———
1
2) you multiply the above by the ratio which favors the relationships: so if the given value is supposed to rise, then the bigger number should be on top, and vice versa. Since no info on # particles is included, that’ll be excluded.
.... 373.15K x 10atm
———— ————
283.15K 1 atm
So 1) multiplied by 2) gives 263.57 mL, which means the answer is none of the choices.
Answer: About 43 billion tons
Explanation:
This is gonna be quite hard to explain.
Answer:- The daughter nuclide is Gallium with atomic number 31 and mass number 68.
Explanations:- Positron emission is also known as beta plus decay. In this type of radioactive decay in which a proton changes into neutron and a positron and electron neutrino are released.
As the proton changes into neutron, mass number remains same but the atomic number decreases by one unit.
The given element is Ge with atomic number 32 and mass number 68. Mass number decreases by one unit means the atomic number of the daughter nuclide would be 31 and it is Gallium.
The equation could be written as:
