The answer would be SrBr2
DIA [1.3K]4 years ago
3 0

Explanation:

Strontium is a metal whereas bromine is a non-metal. Therefore, strontium will donate its excess electrons to bromine atom in order to become stable. Hence, both Sr and Br will combine together to form an ionic bond.

The reaction between strontium and bromine is as follows.

           Sr^{2+} + Br^{-} \rightarrow SrBr_{2}

Calculate the empirical formula for each of the following natural flavors based on their elemental mass percent composition.
tamaranim1 [39]

Answer:

Nitroglycerin- CNH2O3

Vanilin- C3H3O

Explanation:

The empirical formula is the simplest formula of a compound. It depicts the ratio of atoms of each element in the compound. It can be obtained by dividing the percentage by mass of each element by its relative atomic mass. The lowest ratio obtained is now used to divide all the previously obtained ratios and whole number values are recorded. This shows the ratio of atoms of each element present, hence the empirical formula.

Anna35 [415]

Answer;

= 64561.95 g/mole

Explanation;

mass of Fe in 100g = .346g

= .346 / 55.8452 moles

= 0.0061957 moles  

These represent 4 moles of Fe in the molecule so moles of hemaglobin

=  0.0061957/4  

= 0.0015489 moles  

these are in 100 g so mass of 1 mole = 100 / 0.0015489

= 64561.95 g / mole

molar mass of hemoglobin = 64561.95 g/mole

When the absolute value of the difference in electronegativity of two adjacent atom in a compound is 1, they are most likely bon
Morgarella [4.7K]

Answer:polar covalent bond

Explanation:

Compounds are formed ether by donating, receiving or sharing of electrons making the bonds between them to  be ionic, or covalent .

Now  according to the rule  of type of bond assignment due to electronegativity difference of atoms

---When the  electronegativity difference is less than 0.5,  the bond formed is nonpolar covalent.

---When   the  electronegativity difference is between 0.5 and 1.6, the bond is considered polar covalent

---When  the  electronegativity difference greater than 2.0, then the bond is ionic.

Therefore, When the absolute value of the difference in electronegativity of two adjacent atom in a compound is 1, they are most likely bonded by  polar covalent bond eg HCl bond , CCL4 bond
