Mechanical waves need to travel through a medium like solid, liquid, and gas.
TRUE or False

Answers

Answer 1

Answer:

Mechanical waves are waves that must go through a medium in order to propagate. Mechanical waves can also be transmitted through solids, so the medium doesn't have to be a gas or a liquid.

Explanation:

Hope this helps! Brainliest would be appreciated. :)

Unfortunately, this is a poorly asked question and none of the answers are truly right. The closest one to correct is C, although this can’t be deduced from this experiment alone.

A is not correct - other elements can produce spectral lines (and even if they couldn’t, this experiment wouldn’t be able to determine that).

B is not correct - elements produce different spectral lines based on the number of protons that are in the nucleus, amongst a number of other things (again, this wouldn’t be able to be determined from this experiment alone).

D is also not correct, hydrogen is a gas at room temperature and the production of the spectral lines comes from ionizing the gas itself.

a student is given a mixture of sand and salt. describe a method the student could use to separate the mixture.

Answers

Salt and sand can be separated by dissolving the salt in water, filtering the mixture, and then evaporating the water to recover the salt.

There is a golden role of solubility, polar solute dissolve in polar solvent and non polar solute dissolve in non polar solvent. Therefore, Salt and sand can be separated by dissolving the salt in water, filtering the mixture, and then evaporating the water to recover the salt.

What is solution?

Solutions are a homogeneous mixture of two or more substances. A solution is a homogeneous mixture of solvent and solute molecules. Solvent is a substance that is in large amount in solution.

Solute is the substance which is in small amount in a solution. Salt and sand can be separated by dissolving the salt in water, filtering the mixture, and then evaporating the water to recover the salt.

Aqueous hydrobromic acid HBr will react with solid sodium hydroxide NaOH to produce aqueous sodium bromide NaBr and liquid water H2O. Suppose 3.24 g of hydrobromic acid is mixed with 2.3 g of sodium hydroxide. Calculate the maximum mass of water that could be produced by the chemical reaction. Be sure your answer has the correct number of significant digits.

Answers

Answer:

7.20 X 10^-2 gm

Explanation:

Aqueous hydrobromic acid HBr will react with solid sodium hydroxide NaOH to produce aqueous sodium bromide NaBr and liquid water H2O. Suppose 3.24 g of hydrobromic acid is mixed with 2.3 g of sodium hydroxide. Calculate the maximum mass of water that could be produced by the chemical reaction. Be sure your answer has the correct number of significant digits.

HBr(aq) + NaOH (S)-----------> NaBr (aq) + H20

mol wt  of HBr = 1 + 79.9  = 80.9

3,24 gm of HBr = 3.24/80.9 = 0.00400moles = 4.00 X 10^-3 moles

mol wt of NaOH =  23.0 + 16.0 +1.01 = 40.0 gm

2.3 gm = 2.3/40.0 = 0.058 moles =5.8 X 10^-2

the reaction of HBr and NaOH is 1:1.  

there are not enough moles of HBr to neutralize all of the NaOH. so

only 4.00X10 ^-3  moles of H2O can be produced

mol weight of H2O is (2 X 1.01) + 16.0 = 18.0

The maximum mass of H2O that can be produced is

18.0 X 4.00X10^-3 = 72.0/1000 =7.20 X 10^-2 gm

Perform the following operations giving the proper number as a benefit get figures in the answer.

Help

Answers

Answer:

Use calculator but first group them one by one and open the bracket by solving them accordingly

The number we get by this operation is 0.016. This number can be taken based on the rules for significant figures.

What is significant figures?

The number of significant figures is the number of digits that are known with certainty plus the last one having some uncertainty. All non zero values are significant and zero preceding first non zero digit is not significant .

For example in 65000, there are only two significant figures.  Similarly in 0.08 only one significant digit is present. Now when we multiply two decimal numbers, the result can only have as many decimal places as there are in the value with fewest decimal places.

First, multiply the numbers inside the bracket.  As per the above rule, the result should contain only two decimal places.

(0.08 ×200×0.004) = 0.06

Multiply by 65000 - 0.06×65000 = 3900

Now divide it by the multiplication product (800× 300), 240000 we get as follows:

3900÷240000 = 0.016

Hence the result of this operation is 0.016.

11) When sodium metal is subjected to violet light, it causes the photoelectric effect. However, red light does not affect
the sodium. Explain this phenomena.

Answers

The phenomena in which violet light causes photoelectric effect and red light does not is because red light does not achieve the minimum frequency for the phenomenon to occur but violet light does.

The phenomenon in which a substance emits electrons when light is incident upon it is called the photoelectric effect.

This electron would not be emitted if the frequency of the light does not exceed a minimum frequency called the threshold frequency.

Since in the case of the sodium metal, violet light causes the photoelectric effect while red light does not.

This implies that red light does not exceed the minimum frequency for the photoelectric effect to occur, but violet light does thereby causing the photoelectric effect to occur.

So, the phenomena in which violet light causes photoelectric effect and red light does not is because red light does not achieve the minimum frequency for the phenomenon to occur but violet light does.

When table salt forms, which action occurs between the reacting elements? (1 point)
O Chlorine donates an electron to sodium.
Sodium shares an electron with chlorine. O Sodium donates an electron to chlorine.
O Chlorine exchanges an electron with sodium.​

Answers

Answer: C: Sodium donates an electron to chlorine.

Explanation:

Sodium wants to lose an electron and chlorine wants to gain an electron to become stable. This is because of their place in the periodic table, sodium being on the very left edge and chlorine on the very right (noble gasses dont count as they are stable to begin with)

Therefore sodium will donate to chlorine so they both become stable with an ionic bond. (another way to tell its ionic is the very large difference in electronegativity)

When table salt forms, sodium donates an electron to chlorine resulting in the formation of bond which is formed when the electronic configurations become stable.

What  is electronic configuration?

Electronic configuration is defined as the distribution of electrons which are present in an atom or molecule in atomic or molecular orbitals.It describes how each electron moves independently in an orbital.

Knowledge of electronic configuration is necessary for understanding the structure of periodic table.It helps in understanding the chemical properties of elements.

Elements undergo chemical reactions in order to achieve stability. Main group elements obey the octet rule in their electronic configuration while the transition elements follow the 18 electron rule. Noble elements have valence shell complete in ground state and hence are said to be stable.
