Which of the following pairs consists of a weak acid and a strong base? (1 point)
notka56 [123]

Answer:

acetic acid, sodium hydroxide

Explanation:

A strong acid is an acid that ionizes in water to give all its hydrogen ion. Weak acid only ionize to a certain degree. Acetic acid (CH3COOH) only ionize to give one hydrogen ion despite having other hydrogen atom. This account for its weak nature as an acid as shown below:

CH3COOH <=> H^+ + CH3COO^-

A strong base is a base that ionizes in water to give all it hydroxide ion. Sodium hydroxide(NaOH) ionizes to give all its hydroxide ions. This make it a strong base as shown below;

NaOH <=> Na^+ + OH^-

How many 2-tablespoon doses are in 4 bottles of medication containing 16 ounces each?
Dima020 [189]

1 tablespoon = 0.5 ounces

We are required to find for 2 table spoons.

2 table spoons = 2 x 0.5 = 1 ounce.

Each bottle has 16 ounce.

Number of bottles = 4

So total number = 4 x 16 = 64 ounces.

Number of 2 table spoons = \frac{64 ounce}{1 ounce}

= 64

Thus there are 64 2-tablespoon doses are in 4 bottles of medication containing 16 ounces each.

.266 mol CO plus .524 Mol H2 gives how many moles of CH3OH
Readme [11.4K]

Explanation:

Carbon monoxide and hydrogen gas reacts together to form methanol:

CO + 2H2 => CH3OH

Since 0.266mol * 2 = 0.532mol > 0.524mol, the limiting reactant here is hydrogen and therefore there will be 0.524mol / 2 = 0.262mol of methanol.

Explain why the law of conservation of energy can mean that we do not have unlimited sources of energy.
oee [108]
<span>The law of conservation of energy states that energy can neither be created nor destroyed - it can only be converted from one form to another. It basically means that energy can't just appear, but has to be converted from existing energy; for example, the chemical energy in petrol is turned into electrical energy to power a car.Remember the total energy of universe is constant,,and no more energy can be drawn from out if we collect all universe's energy at a single point(its the big bang energy splitted during </span>

Give reasons that might help explain the following observations:
marin [14]

The Benzenesulfonic acid does not undergo Friedel-Crafts alkylation because of the deactivation of the compound by the  carboxylic group.

<h3>What is the Grignard reagent?</h3>

The Grignard reagent is a compound that contains alkyl magnesium halide.

a) The student will be  unsuccessful to prepare a Grignard reagent from 4-bromocyclohexanol because of the -OH group that reacts with the Grignard reagent when formed.

b) The Benzenesulfonic acid does not undergo Friedel-Crafts alkylation because of the deactivation of the compound by the  carboxylic group.

c) The compound (2S, 3R)- 2,3-Dibromobutane has a specific rotation, [a]D, 0⁰ because it is a meso compound.

d) This is because, the tertiary alkyl halide is more prone to elimination reaction giving the alkene.

e) This is because, the reaction may be occurring by an SN1 mechanism and the rate determining step is the formation of the carbocation.
