If you wanted to find a sample of fermium,which has an atomic mass of 100 I would look deep under the earth
The word that is in an incorrect place in the chart is HAIL.
The state of matter of hail is not plasma; hail is a solid at room temperature. Plasma refers to the state of matter in which an ionized gas have approximately equal number of positively and negatively charged ions. Thus, plasma is an ionized gas. Plasma is considered to be the fourth state of matter. <span />
Answer:
A. Has a faster-moving molecules than the same cup of iced tea.
Explanation:
The keyword hear is <em>hot</em>. Immediately, we can conclude that it has more energy than a cup of iced tea. Heat is a form of energy. This type of energy is given to the molecules in the hot cup of tea which makes them really excited. When they're excited, they have many more collisions and thus move much faster. Although the molecules in a cup of iced tea are still moving, their energy is greatly reduced than that of a cup of hot tea (which has energy being added to it through the form of heat).
Answer:
The amount of molecules → 6.02×10²³
Explanation:
Avogadro Number (NA) is the amount of particles that are contained in 1 mol of anything.
It does not matter the mass of compounds, or molecules, 1 mol has 6.02×10²³ particles, the same number for every compound.
1 mol of H₂O that weighs 18 grams has 6.02×10²³ molecules
1 mol of sucrose, that weighs 342 g has 6.02×10²³ molecules
Generally, the NA is the number of atoms in 12 grams of the carbon-12 isotope.
Among these Options the Option B contains a Balance chemical equation. Equation is as follow,
<span>2Na </span>₍s₎<span> + MgF</span>₂<span> → 2NaF </span>₍s₎ <span> + Mg </span>₍s₎
There are two Na atoms (or moles) at right hand side and two at left hand side.
There are two F atoms (or moles) at right hand side and two at left hand side.
There is one Mg atom (or mole) at right hand side and one at left hand side.
