There is this thing called isotopes
it means that atoms of the same element can have a different number of neutrons.
if there is a change in the no. of neutrons, there will definitely be a change in the mass number.
so the answer is A) mass number
Answer:
5.82% ^54Fe, 91.66% ^56Fe, 2.91% ^57Fe and 0.33% ^58Fe.
Explanation:
53.940 amu, 55.935 amu, 56.935 amu and 57.933 amu.
Answer:
Yes, the investigations will reach similar conclusions about the reactivity of H2 and Cl2
Explanation:
1. The law of multiple proportions says that when elements form compounds, the proportions of the elements in those chemical compounds can be expressed in small whole number ratios. This means that regardless of whether 1000 times more of the products are used, the reactivity of the products is established by the chemical reaction
2. The law of multiple proportions is an extension of the law of definite composition, which states that compounds will consist of defined ratios of elements.
3. A reaction with more reactants will need more care because more products are produced, which can be toxic
4. H2 and Cl2 reactivity does not depend on the quantities but the chemical properties of each compound
Answer:
The correct option is;
a. HIPAA
Explanation:
The federal law which safeguards Personal Health Information (PHI) is the health Insurance Portability and Accountability (HIPAA) Act of 1996 with rules regarding the security, privacy and transmission (electronically) of medical health data, was passed to improve the ease healthcare movement between healthcare providers has also added new limitations on PHI disclosure
The HIPAA restricts with whom, when, how and where PHI can be disclosed including physically (direct in person or writing) or electronically (online, over the phone)
Therefore, Jamal had violated HIPAA.
Answer:
(1) addition of HBr to 2-methyl-2-pentene
Explanation:
In this case, we will have the formation of a <u>carbocation</u> for each molecule. For molecule 1 we will have a <u>tertiary carbocation</u> and for molecule 2 we will have a <u>secondary carbocation</u>.
Therefore the <u>most stable carbocation</u> is the one produced by the 2-methyl-2-pentene. So, this molecule would react faster than 4-methyl-1-pentene. (See figure)
