In this case, when converting scientific notation to standard notation, we simply have to multiply the given number by 10^{x}x.
The answer will be 7.510^{2} = 7.5100 = 750
A standard notation is a form of writing a given number, an equation, or an expression in a form that follows certain rules. For example, 4.5 billion years is written as 4,500,000,000 years.

The number of neutrons is the difference between the mass number and the number of protons.
You get the element by looking at the atomic number which is the number of protons. In this case, it is 9 and yes, it is F.
<span>However it is not an atom because it has 10 electrons so you have a fluoride ion F-. </span>
<span>The number of neutrons = 19 - 9 = 10
Therefore, the answer is D.

Answer:hemoglobin that has a high affinity for oxygen
Explanation:
Haemoglobin is the oxygen carrying pigment in blood. It performs this function because of the presence of iron at the center of the haemoglobin which coordinates reversibly with oxygen thereby aiding delivery of oxygen to cells. At high altitudes where air is thinner and the partial pressure of oxygen is lower than sea level, haemoglobin must develop a greater affinity for oxygen in order to carry the scarce oxygen to cells.
