A student drops a 95g object into a graduated cylindor that has 30ml of water in it. After the object is added to the cylinder the water level reads 63ml. What is the density of the object?
Answers
Answer:
The answer is 2.88 g/mLExplanation:
The density of a substance can be found by using the formula
[tex]density = \frac{mass}{volume} \\ [/tex]
From the question
mass = 95g
volume = final volume of water - initial volume of water
volume = 63 - 30 = 33 mL
We have
[tex]density = \frac{95}{33} \\ = 2.87878787...[/tex]
We have the final answer as
2.88 g/mLHope this helps you

what is the definition of chemical formula?
Answers
Answer:
A chemical formula is a way of presenting information about the chemical proportions of atoms that constitute a particular chemical compound or molecule, using chemical element symbols, numbers, and sometimes also other symbols, such as parentheses, dashes, brackets, commas and plus and minus signs. These are limited to a single typographic line of symbols, which may include subscripts and superscripts. A chemical formula is not a chemical name, and it contains no words. Although a chemical formula may imply certain simple chemical structures, it is not the same as a full chemical structural formula. Chemical formulae can fully specify the structure of only the simplest of molecules and chemical substances, and are generally more limited in power than are chemical names and structural formulae.

POSSIE Gallium (Ga) is a soft, silvery metal used primarily in electronic circuits, semiconductors, and light-emitting diodes (LEDs). It is also useful in high-temperature thermometers, barometers, pharmaceuticals, and nuclear medicine tests. Which electron configuration represents the electrons in an atom of gallium at ground state? O1s 2s22p63s23p64524d104p? O 182 2s22p63s23p64s24p1 o 1s 2s22p63s23p64823d104p? O 182 2s22p63s23p64s3
Answers
The ground state configuration : 1s²2s²2p⁶3s²3p⁶3d¹⁰4s²4p¹
Further explanationElectrons can move the shell up or down by releasing energy or absorbing energy
It can be concluded that there are 2 conditions:
Ground-state is the state of electrons filling the shell with the lowest energy levels.
Excited-state is the state of electrons which occupies a higher energy level
The state of excited electrons can be seen from the presence of electrons which do not fill the shell completely but fill the shell afterward
Gallium (Ga) is a metal located in group 13, p-block and period 4
Atomic number : 31
If we look at the options:
options 1,2 and 3 do not conform to Aufbau principle(Electrons occupy orbitals of the lowest energy level ), because 3d orbitals do not exist and the number of electrons is also not 31
So that the most appropriate electron configuration is:
1s²2s²2p⁶3s²3p⁶3d¹⁰4s²4p¹ = 31 electrons
or we can write : [Ar] 4s² 3d¹⁰ 4p¹

What do we call the molecule that forms when two atoms of the same element are covalently bonded to each other?
Answers
Answer:
Covalent Compounds and Diatomic Elements
Explanation: The two atoms that are held together by a covalent bond may be atoms of the same element or different elements. When atoms of different elements form covalent bonds, a new substance, called a covalent compound, results. Water is an example of a covalent compound.
Identify the reactants and products, and describe the change in energy that occurs as bonds are broken and formed.
Answers
Answer:
Chemical reactions almost always have a change in energy between products and reactants. The total energy of a system must remain the same and sometimes a chemical reaction will absorb or release energy as light, heat or both. The energy change in a chemical reaction is caused by the amount of stored energy between the products and the reactants.

B)Every ketone molecular formula is unique.
C) Aldehydes are similar to ketones, but their carbonyl group is located in the middle of the carbon chain.
D) In ketones, the carbon of their carbonyl group is bonded with one other carbon.
Answers
Answer:
A) In aldehydes, the carbon is always joined to at least one hydrogen atom.
Explanation:
Aldehydes and Ketones are organic compounds.
The main difference between them is that aldehydes have the carbon atom attached to at least one hydrogen atom.
In ketones, the carbon is attached to another carbon.
The IUPAC names of alkanals usually end with -eFor alkanones usually end with -oneTo reiterate, the striking difference between the two families is that in alkanals, a hydrogen atom is directly attached to the carbonyl group while in alkanones, no hydrogen atoms is attached to the carbonyl group but two bulky alkyl groups.

What is the wavelength of a radio wave with a frequency of 1.2 × 106 Hz? 3.6 × 1014 meters 3.6 × 102 meters 2.5 × 102 meters
Answers
Answer:
2.5 × 102 meters
Explanation:
Wavelength, which is denoted by λ, can be calculated using the formula:
λ = v/f
Where λ = wavelength (m)
v = speed of light (3×10^8m/s)
f = frequency (Hz)
According to the given information I n the question, f = 1.2 × 10^6 Hz, v = 3×10^8m/s
Hence;
λ = v/f
λ = 3 × 10^8 ÷ 1.2 × 106
λ = 3/1.2 × 10^ (8-6)
λ = 2.5 × 10^2
Therefore, the wavelength of the radio wave is 2.5 × 10^2 meters

A piece of metal of mass 27 g at 93° C is placed
in a calorimeter containing 59.2 g of water at
21°C. The final temperature of the mixture is 34.9 ° C. What is the specific heat capacity of the metal? Assume that there is no energy lost to the surroundings.
Answer in units of J/g. ° C
Answers
Answer:
1.586 J/g°C
Explanation:
So, we have the formula [tex]q = mc\Delta t[/tex].
Since heat released by the metal is = to the heat absorbed by the water (because they eventually become the same temperature in solution), we can say
[tex]m_{water}C_{water}(T_{water}-T_f) = - m_{metal}C_{metal}(T_{metal} - T_f)[/tex]
Plugging in, we get:
[tex]59.2*4.184*(21- 34.9) = - 27*C_{metal}*(93 - 34.9)[/tex]
Solving, we get [tex]C_{metal} = 1.586[/tex] J/g°C.
