Name the following cycloalkane:

CH2CH2CH2CH3
A. butylcyclohexane
B. butylcyclopentane
C. propylcyclohexane

Answer:

0.0125mol

Explanation:

Molarity (M) = number of moles (n) ÷ volume (V)

n = Molarity × Volume

According to this question, a 0.05M solution contains 250 mL of NaOH. The volume in litres is as follows:

1000mL = 1L

250mL = 250/1000

= 0.250L

n = 0.05 × 0.250

n = 0.0125

The number of moles of NaOH is 0.0125mol.

Answer:

its B) Thermohaline currents  Sorry if its wrong but im sure this could be it

Explanation:These deep-ocean currents are driven by differences in the water's density, which is controlled by temperature (thermo) and salinity (haline). This process is known as thermohaline circulation. In the Earth's polar regions ocean water gets very cold, forming sea ice.

Thermohaline currents deep-sea currents that occur because of differences between the salinity and temperature characteristics of water masses

Thermohaline currents is also known as 'the ocean conveyor belt' or 'the global conveyor belt'. It is a part of the large scale ocean circulations.

As the name thermohaline suggested that, 'thermo' means heat and 'haline' refers to the salt content. So, when there is a great difference in the temperature and the salt content deep sea currents occur.

Hence option (2) is correct i.e. thermohaline currents occur due to temperature and salinity difference.

Nitrogen=21.1999%

Hydrogen=6.1023%

Sulfur=24.2660%

The percent composition of nitrogen, hydrogen, sulfur , oxygen in ammonium sulfate is 21.18%, 6.05%,24.21%,48.43% respectively.

The percent composition  is defined as a convenient way to record concentration of solution.It is a expression which relates solute to solvent as,mass of solute/mass of solution ×100.It helps in elemental analysis of a given compound by giving proportions in which they are present.

Percent composition of N= 28/132.14×100=21.18%

Percent composition of H=8/132.14×100=6.05%

Percent composition of S=32/132.14×100=24.21%

Percent composition of O=64/132.14×100=48.43%.

Thus, the percent composition of nitrogen, hydrogen, sulfur , oxygen in ammonium sulfate is 21.18%, 6.05%,24.21%,48.43% respectively.

Oh sheesh girl.. this is tricky.. but I can try:)

Between the chemical reaction of the chemicals and the label on the bottle the ions from in the radioactive product contained in the bottle separates the label from the surface. Im guessing that due to the "radioactive waste" in the bottle that there are components of thermal heat, that may also have an effect on the "label".  So when talking about the reaction we have a chemical and thermal reaction happening.

Answer:

Answer:

B

Explanation:

Answer:

2 M

Explanation:

NaOH + HCl --> NaCl + H2O,

5.54 mL = .00545 L,

If we consider 2.18 M, M [molarity] = mol/L, so we have 2.18 mol/L. From this we can get the moles of NaOH.

.00545 L *  2.18 mol/L ≈ .0121 mol

The concentration of HCl can be found from the following:

.0121 mol = .00619(x) [where x = concentration of HCl]

x = 1.955 M ≈ 2 M

We equate the two as we require the same amount in order to neutralize the base.

Answer: 59.41

Explanation:

The final temperature of the system has been 130[tex]\rm ^\circ C[/tex].

Specific heat can be defined as the amount of heat required to raise the temperature of 1 g of substance by 1-degree celsius.

The amount of heat lost and the heat gained have been equal.

Heat = mass × specific heat × change in temperature

Thus,

mc[tex]\Delta[/tex]T = mc[tex]\Delta[/tex]T

50 g × (10 - x) = 120 × (x - 80)

500 - 50x = 120x - 9600

70x = 9100

x = 130

Thus, the final temperature of the system has been 130[tex]\rm ^\circ C[/tex].

Answer:A) H20 gas

Explanation:

Based on the property of gases, 1-gram sample of hydrogen gas, H₂ in a sealed 1-liter container will occupy the container completely and uniformly.

Gases are one of the states of matter.

Gas molecules have negligible forces of attraction between them, therefore, they are always in motion.

Gases do not have a specific shape or volume, rather they fill up every available space in their container.

Of the given option, only H₂ is a gas.

Therefore,  1-gram sample of hydrogen gas, H₂ in a sealed 1-liter container will occupy the container completely and uniformly.
