Answer:
a. In a mineral the constituent atoms are bonded in a regular, repetitive, internal structure; a rock is a lithified or consolidated aggregate of different mineral grains.
Explanation:
In the internal structure of a mineral the atoms are arranged in an orderly manner, forming shapes that are repeated throughout the structure.
Rocks are a mixture of other materials consolidated in one, which include minerals.
So the minerals have a defined internal structure with atoms in a regular and repeated configuration, while a rock, being a consolidated aggregate, combination of other materials including minerals, does not have a structure that defined
The answer for that is 16, math right?
Answer:
volume of gas=101.94L
Explanation:
Suppose given gas follows the ideality nature of gas
PV=nRT
n=35.8/44mol=0.814 mol
P=0.197atm
T=27.5C=300.5K
R=0.0821atm/mol/K
after putting all value we get,
V=101.94L
volume of gas=101.94L
Nuclear reactions involve a change in an atom's nucleus, usually producing a different element. Chemical reactions, on the other hand, involve only a rearrangement of electrons and do not involve changes in the nuclei.
<h3>What affects the rate of nuclear reactions?</h3>
Reactant concentration, the physical state of the reactants, and surface area, temperature, and the presence of a catalyst are the four main factors that affect reaction rate.
<h3>What is the main difference between chemical reactions and nuclear reactions?</h3>
Chemical reaction normally occurs outside the nucleus. Nuclear reaction happens only inside the nucleus. When chemical reactions occur elements hold their identity and the nuclei of atoms also remains unchanged. During nuclear reactions, the nuclei of atoms changes completely and new elements are formed.
