Answer: opaque means not able to see through. An example is that a window is not opaque because you can see through it, but a rock is opaque.
Answer: Ionic bonding is a type of chemical bonding that involves the electrostatic attraction between oppositely charged ions, or between two atoms with sharply different electronegativities, and is the primary interaction occurring in ionic compounds.
Explanation:
Answer:
The benedict test
Explanation:
when u add benedict solution to a monosaccharide (glucose) containing food it shows a variety of colours as follow and finally turns into a brick red precipitate
blue-green-greenyellow-orange-brick red precipitate.
hope it helped,please let me know!!!
Answer:
A. Atoms randomly crashing into each other
E. The force of one object pushing against the force of another object.
Explanation:
Forces can be classified into two categories based upon the the mode of transfer or application:
1. Contact forces
2. Non-contact forces
Contact forces are the ones which require the physical contact of the matter to get transferred and tend to create the affect. Whereas non-contact forces have the field property which transfers the affect of force from one point to another without any physical contact of the matter or the medium.
- Atoms crashing onto each other have some mass and velocity which upon collision impacts the other atoms exerts a contact force.
- The interaction between the charged particles due to their charges is always due to the electric field be it electron or proton, be it within an atom or out of an atom.
- The force between any two objects pushing or pulling each other is also possible only due to contact.
The theoretical yield of a reaction is 28% if 25.0 grams of product were actually produced from a reaction that has a 88% yield .
The theoretical yield of a reaction is calculated in following steps .
Identify the limiting reagent, which is the reagent with the fewest moles.
Divide the fewest number of reagent moles by the stoichiometry of the product.
Multiply the result of Step 3 by the molecular weight of the desired product.
theoretical yield : the maximum amount of product that can be produced from a given amount of reactant. this quantity of product is rarely produced during a chemical reaction. limiting reactant.
