Answer:
Corresponds to a covalent compound.
Explanation:
Both Boron and Fluorine are nonmetals, forming a covalent bond, the result of which is the boron trifluoride compound (BF3). This is a highly toxic gas.
It is synthesized by the reaction between hydrogen fluoride and boron oxide:
B2O3 + 6 HF → 2 BF3 + 3 H2O
When sodium phosphate reacts with sulfuric acid, forming sodium sulfate and phosphoric acid, the stoichiometric coefficient for sulfuric acid in the balanced chemical equation is 3.
In every balanced chemical equation, the total number of individual atoms on the reactant side must be equal to the total number of individual atoms on the product side. The stoichiometric coefficient is the number written in front of each reactants and products that tells how many moles of each are needed in the reaction.
The chemical equation for the given reaction is:
+ 
= 
+ 
Put the necessary stoichiometric coefficient to balance each element.
Balancing Na:
+ = 
+
Balancing P:
+ = + 
Balancing S:
+ 
= +
Notice that H and O are already balanced.
Hence, the balanced chemical equation for the reaction is:
+ = +
where 3 is the stoichiometric coefficient of sulfuric acid, .

Answer:
The compound with the correct formula is;
A. MNO₃
Explanation:
The number of oxidation states in the metal, M = One oxidation state
The formula of the compound formed by the metal, M = MHCO₃
We note that the ion HCO₃⁻, known as hydrogen carbonate has an oxidation number of -1
Similarly nitrate, NO₃⁻ has an oxidation number of -1, therefore, the metal M can form similar compound formed with HCO₃⁻ with nitrate, and we have;
The possible compounds formed by the metal 'M' includes MHCO₃ and MNO₃.
Answer:
question two is most likely you can describe the shape as a twisted ladder, thats what I learned in school.
Explanation:
YW
Answer:
he rise in the temperature from the sunlight results in the expansion of the water inside the syringe given the external temperature is higher than that of the fluid temperature. ... This is the reason for the little puddle of water to appear under the syringe tip after ten minutes in the sun.
