Answer:

The larger an atom is, the more reactive it will be.

It helps to think about the size of an atom with the location of the electrons and nucleus in mind. You know that protons are positively charged and electrons are negatively charged, therefore there is a level of attraction between these two oppositely charged subatomic particles. This attraction helps stabilize the atom.

Now, in a larger atom, with more electrons are those electrons (specifically the valence electrons) going to be closer or further from the nucleus than in a smaller atom?

They will of course be further from the nucleus and therefore further from the positively charged nucleus. This makes it easier for the valence electrons to leave the atom and form an ionic bond or to interact with another atom to form a covalent bond.

If electrons can leave more easily, then the atom is more likely to react.

What is the speed of a truck that travels 120km in 1.5 hours? Give your answer in km/hr.

Sonja [21]

Explanation:

Hey, there!!

Given,

distance (s)= 120km

Time (t) = 1.5 hrs.

speed = ?

We have,

$speed = \frac{s}{t}$

$speed = \frac{120}{1.5}$

Therefore, the answer is 80km/hr.

Hope it helps...

The reaction between calcium carbonate (CaCO3) and HCl produces calcium chloride (CaCl2), carbon dioxide (CO2), and water (H2O).

Lisa [10]

When the hydrogen chloride concentration doubles, the number of collisions between the reactants becomes increased, which causes the rate of the forward reaction to be faster.

<h3>What is the rate of a reaction?</h3>

The rate of a reaction is how fast a chemical reaction occurs i.e. the conversion of reactants to products.

The rate of a chemical reaction can be influenced by certain factors including the concentration of reactants.

The more the concentration of a reactant, the more the collision between the reactants and hence, the faster the reaction will proceed.

Therefore, when the hydrogen chloride concentration doubles, the number of collisions between the reactants becomes increased, which causes the rate of the forward reaction to be faster

How is a hydroponic garden different from a normal garden?

guapka [62]

The hydroponic garden is different than a normal garden because the plants are required to find more components in the soil. One more difference among hydroponic gardening or ordinary gardening is that hydroponics could be complex. fertilizer for hydroponic growing are usually in more immaculate structure than are regular fertilizer.

How much water needs to be added to 100 mL of a 20%w solution of copper (II) sulfate to prepare a 0.01-M solution?

Alisiya [41]

Answer:

12430mL of water must be added

Explanation:

To solve this question we need to convert the 20%w of CuSO₄ to molarity. Then, using the diulution factor we can find the amount of water required:

20g CuSO₄ / 100mL * (1mol / 159.609g CuSO₄) = 0.1253 moles / 100mL = 0.1253mol / 0.1L =

1.25M is the concentration of CuSO₄. To dilute this concentration to 0.01M, the dilution factor must be of:

1.25M / 0.01M = 125 times must be diluted the solution.

As the volume of the concentrated solution is 100mL, the total volume of the solution to have a 0.01M solution must be of:

100mL * 125 times = 12530mL is the final volume of the solution. That means the amount of water added must be of:

12530mL - 100mL =

<h3>12430mL of water must be added</h3>
