Shown in the table below are solubility data for different salts in water at 60oC.
Which salt is most soluble at 60o C?
A, B, C, or D.
(Chart Below:)
Answer:
D is the most soluble in water at 60 degrees Celsius
According to the data given in the table, the salt is most soluble at 60o C - salt D.
In the given table it is given that all the salts are soluble in different concentrations in different concentrations of the water at the same temperature of 60 degrees celsius.
Salt A - 10/ 50 grams H₂OSalt B - 20/60 grams H₂OSalt C - 30/120 grams H₂OSalt D - 40/120 grams H₂OConverting them in the same amount of H₂O that is 100 grams in the same ratio:
Salt A - 10/ 50 = x/100 gram = 20 gram/ 100 gram H₂OSalt B - 20/60 = x/100 grams = 33.3 gram/ 100 gram H₂OSalt C - 30/120 = x/100 grams = 25 gram/ 100 gram H₂OSalt D - 40/120 = x/100 grams = 50 gram/ 100 gram H₂OThus, the salt D is the most soluble that is 50 grams per 100 gram H₂O.

1. What is the density of a 75 g block of wood measuring 12 cm x 8 cm x 9 cm?
Answer:
0.087 g/cm^3
Explanation:
Density is Mass : Volume.
Volume = 12 x 8 x 9 = 864 cm^3
Mass = 75 g
Density = 75g/864 cm^3 = 0.087 g/cm^3
The density of a 75 g block of wood measuring 12 cm x 8 cm x 9 cm is 8.6 x 10⁻⁵ Kg/cm³.
What is density?
Density is defined as the mass per unit volume of the body. Mathematically-
ρ = M/V
Given is a 75 g block of wood measuring 12 cm x 8 cm x 9 cm.
We can write -
Mass = [m] = 75 g = 75/1000 = 0.075 Kg
Volume = [V] = L x B x H = 12 x 8 x 9 = 864 cm³
Therefore, the density of the object will be -
ρ = M/V
ρ = 0.075/864
ρ = 8.6 x 10⁻⁵ Kg/cm³
Therefore, the density of a 75 g block of wood measuring 12 cm x 8 cm x 9 cm is 8.6 x 10⁻⁵ Kg/cm³.

which formation is a result of a hotspot
Answer:
Hotspots occur when one of the Earth's plates moves over an unusually hot part of the Earth's mantle. These hot areas are usually relatively stationary and result in large amounts of magma rising up, piercing a hole in the plate to form a volcano. As the plates move, a series of volcanoes can form.

A sample of sodium hydroxide of volume 13.9 mL was titrated to the stoichiometric point with 20.6 mL of 0.209 M HCl(aq). What is the initial molarity of NaOH in the solution? Answer in units of M
Answer:
Explanation:
NaOH + HCl = NaCl + H₂O
1 mole 1 mole
moles of hydrogen chloride reacted = .0206 x .209
= 4.3054 x 10⁻³ moles .
moles of sodium hydroxide reacted will be same = 4.3054 x 10⁻³ moles
Let x be the molarity of NaOH
13.9 mL of x molarity will contain
.0139 x moles
.0139 x = 4.3054 x 10⁻³
13.9 x 10⁻³ x = 4.3054 x 10⁻³
x = .3097 M .
= .31 M .

The frequency of the musical note F3 is 1.85 102 hertz. What is its period?
A 5.40 x 10-3seconds
B. 1.05 x 10-3 seconds
C. 3.09 x 10-3 seconds
D. 5.31 x 10-1 seconds
Answer: 0.0054 s
Explanation: There is an inverse relation between the frequency and the period of a wave (a sound wave in this case):
T=1/F
Where f = 1.85 (10)² H z
Hence : T = 1/1.85 (10)² H z T =0.0054s
A single electron configuration can represent multiple atoms. The one below represents the following atoms with different charges. Determine what charge they need to match the electron configuration. 1s²2s²2p⁶3s²3p⁶4s²3d⁷
Answer:
To have the electronic configuration equal to 1s²2s²2p⁶3s²3p⁶4s²3d⁷, the chemical element must have an electrical charge equal to 27, that is, it must have 27 electrons, such as Cobalt (Co), for example.
Explanation:
The electronic configuration shown in the question above is known as the Linus Pauling distribution and represents the energy sub-levels that an electrically charged atom can have in relation to the amount of electrons it has.
The layers sub-levels are presented in the following order 1s² 2s² 2p⁶ 3s² 3p⁶ 4s² 3d¹º 4p⁶ 5s² 4d¹º 5p⁶ 6s² 4f14 5d¹º 6p⁶ 7s² 5f14 6d¹º 7p⁶. Where the small numbers represent the number of electrons in each sub-level and the large numbers represent the layers of electronic distribution.
Accordingly, we can see that an atom that has the configuration 1s²2s²2p⁶3s²3p⁶4s²3d⁷ has 27 electrons, like Cobalt.
