Determine the final temperature of a mixture of 50 grams of water at 10 C added to 120 grams of water at 80 C. Show all work. Use the simulator to check your answer. (Hint: This is a weighted average.)
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].

Calculate the number of moles of NaOH contained in 250. mL of a 0.05M solution.
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.

5. Now you want to know the distance in AU to each place where
you will be traveling. That way, you can relate each distance to our
solar system. What conversion factor will you need to multiply by to
convert kilometers to AU? (Hint: 1 AU = 149,598,000 km)
Answer:
Multiply the length value by 6.68456e-9
Explanation:
The question involves converting from one unit (kilometers) to another unit (Au)
From the question;
149,598,000 km = 1 AU
1 km = x
Cross multiplying;
1 * 1 = x * 149,598,000
1 = 149,598,000x
x = 1 / 149,598,000
x = 6.68456e-9
To convert kilometer to Au; Multiply the length value by 6.68456e-9

_________deep-sea currents that occur because of differences between the salinity and temperature characteristics of water masses
Lesson 2.12
Question 3 options:
Density
Thermohaline currents
Salinity
Polar ice caps
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
What is thermohaline currents?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.

What is the % of each element in (NH4)2(SO4)?
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.
What is percent composition?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%.

It takes 5.54 mL of a 2.18 M NaOH solution to neutralize 6.19 mL of an HCl solution. What is the concentration of the HCl solution? Do not include units in your
answer. Round to the tenths place or further.
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.

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.

Explanation:
Potassium will just be K
Chlorine gas is part of BrIClHOF, which are diatomic gasses. So Cl₂
Looking at the periodic table potassium K has an ion charge of +1 and chlorine Cl has an ion charge of -1, so in a balanced compound they will be written as KCl

While studying meiosis and mitosis for her genetics test, Marisa made notes of the kinds of cells produced from these processes with examples from the body. Which pairing of the cell produced during meiosis and example is correct?
A) diploid cell: liver cell
B) diploid cell: sperm cell
C) haploid cell: egg cell
D) haploid cell: hair cell
Answer:
C
Explanation:
The pairing of the cell produced during meiosis and correct example is haploid cell: egg cell (Option C).
A haploid (n) cell contains only a set of homologous chromosomes, whereas a diploid (2n) cell contains two sets of homologous chromosomes. Meiosis is a type of reductional cell division by which a parental diploid (2n) cell generates four haploid germinal (egg) daughter cells having half of the genetic material.Conversely, mitosis is a type of cell division that produces two genetically identical daughter cells.Meiosis produces germinal (sex) cells, whereas mitosis produces somatic (body) cells.In conclusion, the pairing of the cell produced during meiosis and correct example is haploid cell: egg cell (Option C).
