Potassium Hydroxide (KOH) when added to the solution would give the highest pH

Explanation:

Bases or Alkali are associated with high pH while Acidic substances are represented by lower pH value.

In the given option

HCl- is a strong acid hence would have pH less than 7

H2SO4- also an acid with a pH less than 7

KOH- base with a pH higher than 7

H20-neutral compound with pH as 7

KOH is a very strong base and dissociates in aqueous solution to give it's corresponding metallic ion and hydroxyl ions (OH-) which are characteristic property of any base.

In the following reaction, which substance is the precipitate? (NH4)2SO4(aq) + Ba(NO3)2(aq) BaSO4(s) + 2NH4NO3(aq
mariarad [96]
Assuming that the reactants are:

(NH4)2SO4 (aq) + Ba(NO3)2 (aq)

and the products are:

BaSO4 (s) + 2NH4NO3 (aq),

then you will have to determine which product is insoluble. You should have access to solubility rules to help you determine this.

According to the solubility rules, the following elements are considered insoluble when paired with SO4:

Sr^2+, Ba^2+, Pb^2+, Ag^2+, and Ca^2+

Therefore, the precipitate will be BaSO4 (s).

A 65.0-gram sample of some unknown metal at 100.0° C is added to 100.8 grams of water at 22.0° C. The temperature of the water r
vampirchik [111]
We do a heat balance to solve this:
(m cp ΔT)water = -(m cp ΔT)metal
100.8 (4.18) (27 - 22) = -65 (cp)(27-100)
cp = 100.8 (4.18) (27 - 22) / (-65 (27-100))
cp = 0.44 J/ (°C × g)

The specific heat of the metal is 0.44 J/ (°C × g)

We can use two equations for this problem.<span>

t1/2 = ln 2 / λ = 0.693 / λ
Where t1/2 is the half-life of the element and λ is decay constant.

20 days = 0.693 / λ 
λ   = 0.693 / 20 days        (1) 

Nt = Nο eΛ(-λt)                (2)

Where Nt is atoms at t time, No is the initial amount of substance, λ is decay constant and t is the time taken.
t = 40 days</span>

<span>No = 200 g

From (1) and (2),
Nt =  200 g eΛ(-(0.693 / 20 days) 40 days)
<span>Nt = 50.01 g</span></span><span>

</span>Hence, 50.01 grams of isotope will remain after 40 days.

Answer:

D. C₄H₁₀ and C₂H₅

<h2>What is a empirical formula?</h2>

A chemical formula indicating the elements of a compound and their relative proportions, as (CH₂O)n.

Since an empirical formula indicates the ratio (proportions) of the elements in the compound, it can be used, along with the molar weight of the compound, to determine the molecular formula.

The empirical formula provides the smallest whole-number ratio among elements or compounds within a molecular compound. A compound is a chemical formed from atoms of different chemical elements.

Hence, Option D is correct.
