Answer: 0.147 grams
Explanation:
To calculate the moles :
According to stoichiometry :
2 moles of 
require = 2 moles of ![NaOH/tex]Thus 0.049 moles of [tex]Al](https://tex.z-dn.net/?f=NaOH%2Ftex%5D%3C%2Fp%3E%3Cp%3EThus%200.049%20moles%20of%20%5Btex%5DAl)
will require=
of 
Thus is the limiting reagent as it limits the formation of product and is the excess reagent.
As 2 moles of give = 3 moles of 
Thus 0.049 moles of give =
of
Mass of 
Thus 0.147 g of will be produced from the given masses of both reactants.
A hydrogen bond is the electrostatic<span> attraction between two polar groups that occurs when a hydrogen (H) atom covalently bound to a highly </span>electronegative<span> atom such as </span>nitrogen. So In Terms nitrogen<span> (N), </span>oxygen<span> (O), or </span>fluorine<span> (F) help form The bonds</span>
Answer:
4.57 × 10⁶ nanometers
Explanation:
In this problem we are asked to convert between two units i.e. a meter into nanometer. In sciences, the different units are used for a same quantity (achieved by multiplying conversion factors) to get rid of very small values and get a readable and intelligible values.
For Example:
In given statement the value of small distance is 4.5 × 10⁻³ meter the real number form of this number is 0.00457. Hence, this number can be converted to a very large number by multiplying it with 10⁹ or 1000000000. Hence,
4.5 × 10⁻³ × 1.0 × 10⁹ = 4.57 × 10⁶
Or,
4.5 × 10⁻³ meters = 4.57 × 10⁶ nanometers
Although the quantity is the same for same units but the number has changed.
Answer:
1. An apple is something that has matter.
2. Light does not have matter. It neither has mass or takes up and space.
3. Physical changes only change the appearance of a substance, not its chemical composition. Chemical changes cause a substance to change into an entirely substance with a new chemical formula. Chemical changes are also known as chemical reactions.
4. A chemical reaction is usually accompanied by easily observed physical effects, such as the emission of heat and light, the formation of a precipitate, the evolution of gas, or a color change. Absolute confirmation of a chemical change can only be validated by chemical analysis of the products!
5. A precipitate is a solid that forms out of solution.
6. In simple terms, the endothermic reactions absorb energy from the surrounding that is in the form of heat. On the other hand, an exothermic reaction releases energy into the surrounding of the system.
Explanation:
Matter is anything that has mass and takes up volume.
The claim that the strongest intermolecular interactions between propanol molecules arises from hydrogen bonding is True.
Intermolecular forces are weaker attraction forces that are utilized to define physical characteristics of molecules such as:
- boiling point
- temperature
- density
- melting points
Hydrogen bonding is an type of intermolecular forces.
It is a type of dipole-dipole interaction that only happens when a hydrogen atom is connected to the atomic element of oxygen, nitrogen, or fluorine.
From the question given, in the propanol (CH3CH2CH2OH) molecule, the hydrogen usually has a partially positive charge which attracts the partially negative charge of the oxygen.
Therefore, we can conclude that the claim is True.
