Answer:
AlF3
Explanation:
Aluminum fluoride is an inorganic compound of chemical formula AlF3. Such a compound originates from the treatment of aluminum hydroxide particles with hydrogen fluoride, which react and give rise to aluminum fluoride. This is a very important solid and crystalline element during the production of other compounds that use aluminum oxides because it has the ability to lower the melting point.
The answer here is D - bases tend to feel slippery. This is because they tend to dissolve oils on your skin, reducing the friction between your fingers or hands when you rub them together.
Answer:- A) glucose has covalent bonds.
Explanations:- Glucose is a molecule that has carbons, oxygen and hydrogen. All these are non metals and do sharing of electrons to gain their nearest noble gas configurations and so glucose has covalent bonds.
Table salt is NaCl. Na is a metal and Cl is a non metal so the bond formed between them is ionic.
Steel alloy has Iron and carbon and so it would have ionic and metallic bonding.
Iron oxide also has a Iron(metal) and oxygen(non metal) and so it has ionic bond.
So, the only and only correct choice is A) Glucose.
Answer:
The answer to your question is: number 1
Explanation:
Third law of Newton: says that for every action ,there is an equal and opposite reaction.
So, if the child is pushing an object to the right, it will recipe the same amount of force that he is exerting to the object but in opposite direction.
Number 2 and 3 are incorrect because, because the third law of Newton says "an equal and opposite reaction", not slightly more or less.
Number 4 is wrong, it is not in agreement with Newton's third law of motion.
Well I need to know the empirical formula, molecular formula.
Then I can multiply the grams of each individual element by their molar mass, and divide the smallest element by itself, and the other elements by the smallest element. Then I get the empirical formula
