Answer:
E
C eg In graphites and diamonds
Answer:
the brain
Explanation:
drugs mainly affect the brain to keep the addiction going
Rubber is not very good at conducting electricity. This is because rubber makes it difficult for electrons to flow between atoms, due to rubber having tightly packed electrons. Materials like rubber are known as insulators.
Conductors are the opposite, they conduct electricity very well. Examples of conductors are metal, which is why metal is used in wires.
Since rubber is not a conductor, answer choice B can be eliminated. This can also eliminate answer choice D, since insulators like rubber don't allow electricity to easily flow.
While rubber gloves keep our hands dry, there are no liquids involved in this experiment and this is not the main reason for using rubber gloves. This eliminates answer choice C.
The answer is A. rubber gloves are insulators.
The teacher instructs the students to wear rubber gloves to prevent them from getting an electric shock.
Answer:
A. rubber gloves are insulators
Hope this helps!
1 mol = 6.022 x 10²³ atoms
In order to find how many atoms, dimly multiply the amount of moles you have by 6.022 x 10²³ or Avogadro's number.
So you have 1.75 mol CHC1₃ x (6.022x10²³) = 1.05385 x 10²⁴ atoms of CHCl₃
But now you have to round because of the rules of significant figures so you get 1.05 x 10²⁴ atoms of CHCl₃
Explanation:
The law of conservation of mass states that mass is conserved which also means that it cannot be created or destroyed within the isolated system.
We can add the mass of the reactant and can be equal to the mass of the product. But in some cases, it will not work like:
If reactants are not in the mole ratio, there will be a limiting reagent.
If a gas is one of reactants or products.
Radioactive decay and nuclear reactions(fission or fusion).
