A lab director asks two students, Lydia and Damien, to each select a bottle of a concentrated weak base. When they reach the cab
algol13

Lydia and Damien should select the bottle of weak base with high molarity(M)

<h3>Further explanation</h3>

According to Arrhenius, Base is a compound which in water releases OH- ions

Electrolytes (acids or bases) with a small degree of ionization are classified as weak electrolytes

If two students, Lydia and Damien, select each bottle of a concentrated weak base, then a guide can be chosen to choose some of the solutions available in the lab :

  • Base compounds are usually known from their names ending in hydroxide suffixes such as NaOH, sodium hydroxide
  • The weak base will be partially ionized in water because the ionization degree is close to 0 or less than 1
  • If there is a Kb value (base ionization constant), then this shows the strength of the base. The greater the value of Kb, the greater the base strength
  • If there are some weak bases, then Lydia and Damien choose the highest concentration, usually indicated by the value of Molarity (M)

Because no choice solution is included, the weak base example is:

Ammonia (NH₃)

Aluminum hydroxide (Al (OH)₃)

Copper (II) hydroxide Cu (OH)₂

Mercury (II) hydroxide Hg (OH)₂

At what temperature (in K) will 3.5 moles of gas occupy 2.7 L at 1.5 atm? HELP PLEASE!
Vesnalui [34]

3.5 moles of a gas will occupy 2.7 L at 1.5 atm at a temperature of 14.1K

IDEAL GAS LAW:

  • The temperature of a gas can be calculated using the ideal gas law equation:

PV = nRT

Where;

  1. P = pressure (atm)
  2. V = volume (L)
  3. n = number of moles (mol)
  4. R = gas law constant (0.0821 Latm/molK)
  5. T = temperature (K)

  • According to this question, P = 1.5atm, V = 2.7L, n = 3.5moles, T = ?

  • 1.5 × 2.7 = 3.5 × 0.0821 × T

  • 4.05 = 0.28735T

  • T = 4.05 ÷ 0.28735

  • T = 14.1K

  • Therefore, 3.5 moles of a gas will occupy 2.7 L at 1.5 atm at a temperature of 14.1K

In which way does a balanced chemical equation demonstrate the conservation of matter?
777dan777 [17]

Answer:

A. It shows the same number of atoms of each element on both sides of the equation.

Explanation:

A balanced chemical equation demonstrates the conservation of matter by showing the number of atoms of each element on both sides of the equation or expression.

According to the law of conservation of matter, matter is neither created nor destroyed in the course of a chemical reaction but atoms are rearranged.

  • Based on this premise, the number of atoms or moles on both sides of the expression must be equal.
  • If there are 3 atoms of carbon on one side, the product must also reflect 3 atoms of carbon.

Why would you get electrocuted if you went swimming in a pool during an electrical storm?
fredd [130]

Answer:

In a swimming pool chlorine ion are mix with water, a polar molecule. In this case the pool is a perfect environment for the conductive solution. The reason why, people can be electrocuted is that the hypochlorite is an ion and in the water, it form an ionic compound.
