Answer:
0.336 J/g/C
Explanation:
Recall the equation for specific heat:
q = mcΔT
1250 = 25 x c x 149
c = 0.336
Define ionization energy and explain why the second aisle and ionization energy of the element is higher than its ionization energy
The energy needed to remove one or more electrons from a neutral atom to form a positively charged ion is a physical property that influences the chemical behavior of the atom. By definition, the first ionization energy of an element is the energy needed to remove the outermost, or highest energy, electron from a neutral atom in the gas phase.
The process by which the first ionization energy of hydrogen is measured would be represented by the following equation.
H(g) -----> H+(g) + e- deltaHo = -1312.0 kJ/mol
oxygen -17 and oxygen-18 are isotopes of oxygen
<em><u>Explanation</u></em>
Isotope is two or more forms of the same element that has equal amount of proton but different number of neutrons in the nuclei.
oxygen -17 and oxygen-18 are isotope of oxygen since they have the equal amount of protons but different number of neutrons in their nuclei.
that is oxygen 17 has 8 protons and 9 neutrons while oxygen 18 has 8 protons and 10 neutrons.
Answer:
LDL is
low density lipid
HDL is
high density lipid
Explanation:
HDL helps rid your body is excess cholesterol so so it won't end up in your arteries
LDL is also called "bad cholesterol" because it takes cholesterol to your arteries
In a place with no gravity
Explanation:
Weight is a force exerted by a body in the presence of gravity.
Weight = mass x gravity
Without gravity, there is no force of weight. The more the gravity, the more the weight of a body.
A body will experience weightlessness in a place without no gravity.
Therefore, one will experience the least weight in a place without the pull of gravity.
