The charge of Fe can either be +2 or +3 and the charge of S is -2 so it would depend one which charge Fe. If the charge is +2 than yes it’s balanced, if +3 then no
Answer:
1 fempto = 10⁻¹⁵
Explanation:
Data Given:
9.2 fempto second = 9.2 ×10 ⁻¹⁵ seconds
exponential equivalent of fempto = ?
Solution:
To find exponential equivalent of fempto
As we know
we look at the given data
That is fempto seconds = 9.2
when we write only seconds then we write 10⁻¹⁵ instead of fempto
that is
9.2 ×10 ⁻¹⁵ seconds
So the exponential equivalent of fempto = 10 ⁻¹⁵
That is -15 exponent to 10
So,
10 ⁻¹⁵ = 0.00000000000001
1 fempto = 10 ⁻¹⁵
The sun transfers its heat energy through radiation which is the transfer of energy by electromagnetic wave motion.
Answer:
1. Oxygen Fluoride (O with F): covalent
2. Calcium Chloride (Ca with Cl): ionic
3. Sodium with Sodium (Na with Na): neither
Explanation:
1. Oxygen Fluoride (OF2)
Oxygen with Fluorine is covalent because both of these elements are <em>nonmetals</em>. Bonds that contain only nonmetals are covalent.
2. Calcium Chloride (CaCl2)
Calcium with Chlorine is ionic because there is one <em>metal </em>and one <em>nonmetal. </em>Bonds that contain one metal and one nonmetal are ionic.
3. Sodium with Sodium
Since this is not Sodium bonding with another element, it is neither ionic or covalent.
A common dry-cell battery is the zinc-carbon battery, which uses a cell that is sometimes called the Leclanché cell. The cell is made up of an outer zinc container, which acts as the anode.
