Answer:

Le Chatelier's principle predicts that equilibrium will shift to decrease the concentration of reactants. Increasing the rate of the forward reaction will mean a decrease in reactants. ... When the concentration of reactants is increased, the equilibrium shifts to the right and there will be more product than before.

What volume in milliliters of concentrated HCl (12 M) is needed to make 1500 mL of a 3.5 M solution?

Leviafan [203]

This process involves the dilution of the 12 molar HCl. To reduce the concentration, we need to set up an equality so that we know how much of the 12M we need to make the 3.5M.

12 moles HCl 3.5 moles HCl
——————— = ———————
1 Liter of Soln ‘x’ Liters of Soln

Notice that the 12 moles over the 1 liter is equal to 12 molar; in doing this, we’re maintaining the concentration of the initial HCl. By setting it equal to the 3.5 over ‘x’, we’re still maintaining the concentration.

After solving, we find that ‘x’ equals 0.292. This value means that in 0.292 liters of our 12 M HCl solution, there are 3.5 moles of HCl. But, we’re not done yet.

0.292 liters of 12 M HCl can make 1 liter of 3.5 M HCl, but the question asks for 1.5 liters. To get this, multiply 0.292 liters by 1.5, and the new result, 0.4375, represents the amount of 12 M HCl required to prepare a 1500 mL 3.5 M HCl solution.

Sodium combines with water to produce sodium hydroxide and hydrogen gas. Which word equation represents this violent reaction?

Natalka [10]

Answer: sodium + water → sodium hydroxide + hydrogen

Explanation:

1) The first part of the statment "sodium combines with water" means that these two pure substances are the reactants.

Sodium is an alkali metal (group 1: Li, Na, K, Rb, Cs, Fr).

A typical chemical property of the alkali metal elments is that they react violently with water fo form the corresponding hydroxide and hydrogen gas.

2) The next two words, "to produce ". indicates, precisely, that what follow is the product of the reaction. In the chemical reaction it is indicated by the arrow →

3) Finally, you are told the products of the reaction: sodium hydroxide and hydrogen gas.

4) The word equation then follows the order reactants → products, which in this case is the sodium + water → sodium hydroxide + hydrogen

5) Using chemical symbols and conventions, that is:

Na(s) + H₂O (l) → NaOH(aq) + H₂(g).

Provide your answer in the following format: [element name], [chemical family]

erastova [34]

Answer: Bismuth (Bi) , Nitrogen family

Explanation:

As the element has 5 valence electrons in the sixth energy level, which mens it belongs to 6th period as the valence electron has entered the 6th energy level.

Now as the electrons are filled according to afbau's rule , the electronic configuration of the element will be :

$[Xe]4f^{14}5d^{10}6s^26p^3$

Now as the atomic number of element is equal to the number of electrons in a neutral atom , the atomic number is 83 and the element is Bismuth (Bi). As the last electron enters p -subshell , it is a p block element. It lies in group 15 which is nitrogen family.
