Answer:

M = 0.47

Explanation:

1 - Turn grams to moles using molar mass:

16g NaOH × 1 mol NaOH / 40g NaOH = 0.4 mol NaOH

2- Turn milliliters to liters:

855mL × 1 L / 1000mL = 0.86 L

3- Use formula which is M = moles of solute / liters of solvent:

M = 0.4 mol NaOH / 0.86 L = 0.47

a sample of gas X occupies 10 m^3 at a pressure of 120 kPa.if the volume of the sample is compressed to 3m^3 ,what is the new pressure of the gas?​

Answers

Answer:

400 kPa

Explanation:

The new pressure can be found by using the formula for Boyle's law which is

[tex]P_1V_1 = P_2V_2[/tex]

Since we're finding the new pressure

[tex]P_2 = \frac{P_1V_1}{V_2} \\[/tex]

120 kPa = 120,000 Pa

We have

[tex]P_2 = \frac{120000 \times 10}{3} = \frac{1200000}{3} \\ = 400000[/tex]

We have the final answer as

400,000 Pa = 400 kPa

What’s the easiest way to add energy to matter

Answers

Answer:

The easiest way is to heat matter which raises its internal energy andso the mass as well. Another possibility is to accelerate matter as in case of protons or heavy ions in the LHC, Protons ,for example , are accelerated to the energies of 6500 GeV which means increase of the rest mass by a factor of almost 7000

convert 555 torr into kpa

Answers

Answer:

73.97 kPa

Explanation:

It's helpful to know the conversion factors and apply them.

First, convert from torr to atm:

555 torr ÷ 760 atm = 0.730 atm

Next, convert from atm to Pa:

0.730 atm × 101,325 Pa = 73967 Pa

Finally, convert to kPa (1000 Pa in 1 kPa):

73967 Pa ÷ 1000 kPa = 73.97 kPa

What is the mass of 8.23 x 10^23 atoms of Ag

Answers

Answer:

[tex]\boxed {\boxed {\sf Approximately \ 147 \ g\ Ag}}[/tex]

Explanation:

Convert Atoms to Moles

The first step is to convert atoms to moles. 1 mole of every substance has the same number of particles: 6.022 ×10²³ or Avogadro's Number. The type of particle can be different, in this case it is atoms of silver. Let's create a ratio using this information.

[tex]\frac{6.022*10^{23} \ atoms \ Ag}{1 \ mol \ Ag}[/tex]

We are trying to find the mass of 8.23 ×10²³ silver atoms, so we multiply by that number.

[tex]8.23 *10^{23} \ atoms \ Ag *\frac{6.022*10^{23} \ atoms \ Ag}{1 \ mol \ Ag}[/tex]

Flip the ratio so the atoms of silver cancel. The ratio is equivalent, but places the other value with units "atoms Ag" in the denominator.

[tex]8.23 *10^{23} \ atoms \ Ag *\frac{1 \ mol \ Ag}{6.022*10^{23} \ atoms \ Ag}[/tex]

[tex]8.23 *10^{23} *\frac{1 \ mol \ Ag}{6.022*10^{23} }[/tex]

Condense into one fraction.

[tex]\frac{8.23 *10^{23} }{6.022*10^{23} } \ mol \ Ag[/tex]

[tex]1.366655596 \ mol \ Ag[/tex]

Convert Moles to Grams

The next step is to convert the moles to grams. This uses the molar mass, which is equivalent to the atomic mass on the Periodic Table, but the units are grams per mole.

Ag: 107.868 g/mol

Let's make another ratio using this information.

[tex]\frac {107.868 \ g \ Ag}{1 \ mol \ ag}[/tex]

Multiply by the number of moles we calculated.

[tex]1.366655596 \ mol \ Ag*\frac {107.868 \ g \ Ag}{1 \ mol \ ag}[/tex]

The moles of silver cancel out.

[tex]1.366655596 *\frac {107.868 \ g \ Ag}{1 }[/tex]

[tex]1.366655596 * {107.868 \ g \ Ag}[/tex]

[tex]147.4184058 \ g\ Ag[/tex]

Round

The original measurement of atoms has 3 significant figures, so our answer must have the same. For the number we calculated, that is the ones place.

147.4184058

The 4 in the tenths place tells us to leave the 7 in the ones place.

[tex]147 \ g\ Ag[/tex]

8.23 ×10²³ silver atoms are equal to approximately 147 grams.

PLEASE HELP QUICKLY!! How many moles of NH4OH are in 0.125L of a 1.4 M solution of NH4OH?

Answers

Answer:

0.175mol

Explanation:

Molarity of a solution can be calculated thus:

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

According to the information provided in this question, volume of NH4OH = 0.125L, molarity = 1.4M

Using; Molarity = n/V

1.4 = n/0.125

n = 0.175mol

What volume of solution is required to produce a 7.8M solution containing 23.6g of LiBr?

Answers

Answer:

34.9 mL

Explanation:

First we convert 23.6 g of LiBr into moles, using its molar mass (86.845 g/mol):

23.6 g ÷ 86.845 g/mol = 0.272 mol LiBr

Now we can calculate the required volume, using the definition of molarity:

Molarity = moles / litersliters = moles / Molarity0.272 mol / 7.8 M = 0.0349 L

We can convert L into mL:

0.0348 L * 1000 = 34.9 mL

A student is dissolving sugar in water to make candy. She notices that sugar lumps are forming at the bottom of the pan. What could she do to help more of the sugar dissolve?
1. Heat the solution
2. Cool the solution
3. Add more sugar to the pan
4. Take some water out the pan

Answers

1. She should heat the solution

The solutes in a solvent can be make more soluble by heating. Thus upon heating the sugar lumps forming at the bottom of the water can be easily dissolved.

What is solubility?

Solubility of substance is the fraction of its concentration which dissolves in a solvent. Solubility is affected by several factors such as temperature, pressure, molecular weight, bond type etc.

Water is known as universal solvent because, it can dissolve almost all the inorganic and organic compounds. The hydroxide ions in water forms hydrogen bonds with compounds and easily dissolve them.

By providing thermal energy the intermolecular attraction of the solute molecules can be weekend and they easily forms bonds with the solvent molecules results in dissolution. Thus option 1 is correct.

Using an analogy of a water balloon, describe the function of the bladder.

Answers

Answer:

A bladder is like a balloon, because it holds urine, just like a balloon holds air. The urethra's function is to excrete urine from the human body.

Explanation:

A bladder and a balloon are similar, because it is the bladder which clasp urine, whereas a balloon clench air. The role of urethra is to eliminate urine from our human body.

What is bladder?

The hollow organ which is in triangle shape and found in the lower abdomen just like a balloon is defined as the bladder. The urinary bladder is also known as a temporary reservoir of urine. Urine is reserved in the urinary bladder till it is removed out through the urethra.

As a result of the contraction of the wall of the urinary bladder, urine is eliminated from the body from time to time. The urine contains waste and extra fluid left over the body which has to be eliminated.

The bladder resembles the water balloon in that it holds urine in the similar way as the water balloon clench water. The water balloon pops when the amount of water exceeds than it can hold.

Thus the function of bladder and water balloon are found to be same.

Acceleration

Explanation:

Acceleration doesn't change one moment to the next, and therefore, doesn't count as a force.

The answer option which is not a force is: C. Acceleration.

What is a force?

A force can be defined as a push or pull of an object or physical body, which typically results in a change of motion (acceleration), especially due to the interaction of the object with another.

The examples of a force.

In Science, the three (3) most common examples of a force include the following:

Answers

Answer:

Explanation:

c. K⁺

d. Mg²⁺

Based on the Bohr's atomic model, the atom has electrons (Mass 0; Charge -1), protons (Mass 1; Charge +1) and neutrons (Mass 1; Charge 0).

The atomic number is equal to the number of protons. That means there are 10 protons. As the Neon is netural, the amount of electrons must be 10.

A neutral atom of Mg has 12 electrons, that means the Mg²⁺ has 10 electrons the same than Ne.

Right option is:

d. Mg²⁺
