Answer:
moon, planet, planet
Explanation:
moons revolve around planets
Jupiter is considered a planet because it revolves the sun
and a planet is a body that revolves a star a dwarf planet doesn't revolve around a star
Answer:
- <em>Chemical equations are balanced </em><u>to comply with the law of conservation of mass.</u>
Explanation:
Law of conservation of mass states that matter cannot be either created or destroyed.
A skeleton chemical equation shows the reactants and products of a chemical reaction without taking into account the real proportion in which the reactants combine and the products are obtained.
An example of a skeleton reaction is the combustion of methane:
Such as that equation is shown, there are four atoms of hydrogen in the reactants but only 2 atoms of hydrogen in the products. Also, there are 2 atoms of oxygen in the reactants but three atoms of oxygen in the products. This seems to show that some atoms of hydrogen have been destroyed and some atoms of oxygen have been created. This is impossible as it is against the law of conservation of matter.
Then, to show a real situation, the chemical equation of combustion must be balanced, adjusting the coefficients. This is the balanced chemical equation:
Now you see that the number of atoms of each matter is conserved: the number of carbon atoms in each side is 1, the number of atoms of hydrogen in each side is 4, and the number of atoms of oxygen in each side is 4. Thus, by balancing the chemical equation, the law of conservation of mass is not violated.
Answer:
3 half-lives
Explanation:
The half-life is the time that it takes to a radioactive element to decay to half of its initial amount.
Let's suppose we start with 64 g of the radioactive element.
- After 1 half-life, the mass of the element will be 32 g.
- After 2 half-lives, the mass of the element will be 16 g.
- After 3 half-lives, the mass of the element will be 8 g.
B) The carbon atoms in graphite are arranged in widely spaced layers
Explanation:
Graphite is different from other allotropes of carbon because the carbon atoms in graphite are arranged in widely spaced layers. Graphite and diamond are the two main allotropes of carbon that are closely related.
- Both allotropes forms under extreme temperature and pressure. In geology, they are categorized as derivatives of changed rocks.
- Graphite is different from carbon because its atoms are arranged in widely spaced layers.
- Diamond has a packed and cross-linked structure that makes it rigid and very hard.
