Explanation:
the molecules in liquids and gases aren't that closely bonded like solids, that's why they can take the shape of the container and move freely.
First, it combines with carbon dioxide in the soil to form a weak acid called carbonic acid. ... Carbonic acid slowly dissolves away minerals in rock, especially the carbonate minerals that make up limestone and marble. The weak acid decomposes the insoluble rock into watersoluble products that move into the groundwater.
Answer:
See explanation
Explanation:
If we look at the structure of X, we will discover that X is an organic compound. The compound will certainly have a much lower melting point than sand.
This is because, sand is composed of high melting point inorganic materials.
Hence, even though the researcher accidentally spilled some sand into the the beaker containing the crystalline substance X, he does not need to be perturbed since the melting point of X is much lower than that of sand
Answer:
55 protons, 78 neutrons, 55 electrons
Explanation:
In a neutral Cesium atom we have 55 protons, 78 neutrons and 55 electrons. This can be found on the periodic table of elements.
Protons are the positively charged particles within an atom
Neutrons do not carry any charges.
Electrons are the negatively charged particles.
The amount of these subatomic particles can be obtained from the periodic table of element.
For a neutral atom, the number of protons and electrons are the same.
Since the atomic number is 55, it is also the number of protons in the atom.
