Answer:
Because X-rays have wavelengths similar to the size of atoms
Answer:
As an example I can say sodium (Na) and chlorine (Cl).
Explanation:
An ionic bond occurs when a metal element reacts with a nonmetal element. Therefore in the answer given above the Na is metal and Cl is nonmetal and they form a molecule through ionic bonding.
Answer:
The number of years it would take you to earn what Mike Trout will earn on his contract is 4,265
Explanation:
Mike Trout of the Los Angeles Angels has a contract worth $426,500,000
On the other side, you earn $100,000 per year.
To calculate the number of years it would take for you to earn what Mike Trout will earn from his contract, you must divide the amount Mike earned by the amount you earned during a year:
$426,500,000 ÷ $100,000 per year= 4,265
The number of years it would take you to earn what Mike Trout will earn on his contract is 4,265
<span>Correct answer is : 72.0 g/mole
If we assume Ideal Gas Law, PV = nRT. n = PV/RT = ((0.988 atm)*(0.258 L))/((0.0821 L*atm/mole*K)*(100 + 273.15)) = 0.00832 moles
Molar mass = 0.599 g/0.00832 moles = 72.0 g/mole; your answer is E.</span>
