Answer:

Explanation:

Reaction rate, in chemistry, the speed at which a chemical reaction proceeds. It is often expressed in terms of either the concentration (amount per unit volume) of a product that is formed in a unit of time or the concentration of a reactant that is consumed in a unit of time. Alternatively, it may be defined in terms of the amounts of the reactants consumed or products formed in a unit of time. For example, suppose that the balanced chemical equation for a reaction is of the form

A + 3B → 2Z.

How did the atomic theory develop
olasank [31]
It was the English chemist, John Dalton, who put the pieces of the puzzle together and developed an atomic theory in 1803. Dalton 's atomic theory<span> contains five basic assumptions:

- All matter consists of tiny particles called </span>atoms<span>.
</span>- Atoms are indestructible and unchangeable.- Elements are characterized by the weight of their atoms.
- In chemical reactions, atoms combine in small, whole-number ratios. 
- When elements react, their atoms may combine in more than one whole-number ratio.

Hope this helped!

How many grams of NaCl should be added to 250 grams of waterto<br> make a 0.40 m solutions?
d1i1m1o1n [39]

Answer : The mass of NaCl added should be, 5.85 grams.

Explanation : Given,

Mass of H_2O = 250 g

Molality of solution = 0.40 mol/kg

Molar mass of NaCl = 58.5 g/mole

Molality : It is defined as the number of moles of solute present in one kilogram of solvent.

Formula used :

\text{Molality}=\frac{\text{Mass of NaCl}\times 1000}{\text{Molar mass of NaCl}\times \text{Mass of water (in g)}}

Now put all the given values in this formula, we get:

0.40mol/kg=\frac{\text{Mass of NaCl}\times 1000}{58.5g/mole\times 250g}

\text{Mass of NaCl}=5.85g

Therefore, the mass of NaCl added should be, 5.85 grams.
