The students in Mrs. Smith's class used pH paper to measure the acidity levels between different samples of breakfast drinks. The pH
measurements ranged from 3.27 to 3.88 on the pH scale. Based on this range, we can determine that the most acidic solution had a pH of:
Answer:
The most acidic solution had a pH of 3.27.
Explanation:
In order to solve this problem we need to keep in mind that the lower the pH of a solution is, the more acidic the solution is.
If among the pH readings across the measured breakfast drinks, the lowest one was 3.27 (as the problem tells us with the range), then that drink was the most acidic one.
Conversely, the least acidic one had a pH of 3.88.
what would cause the different liquids to have different density
Answer:
The same amount of two different liquids you used in the container will have different densities because they have different masses. The liquids that weigh more (a higher density) will sink below the liquids that weigh less (a lower density).

In the number 48.93, which digit is estimated?
In the number 48.93, the digit that is estimated is the digit "9."
In the number 48.93, the digit "9" is estimated because it falls after the decimal point. When a decimal number, the digits to the right of the decimal point represent fractional or decimal values.
These digits can be estimated or rounded to a certain degree of accuracy, depending on the context or the desired level of precision.
The digit "9" is the last digit after the decimal point, it is likely an estimated value. It means that the actual value could be slightly higher or lower than 9, depending on the level of precision required.

across the period the size of an atom decreases and effective nuclear charge
Answer:
Atomic radius decreases across a period and increases down a group. Across a period, effective nuclear charge increases as electron shielding remains constant. Down a group, the number of energy levels (n) increases, so there is a greater distance between the nucleus and the outermost orbital.

A gas occupies 40.0 mL at 150 K. What volume does it occupy at 300 K,
assuming pressure is constant? *
Answer:
.08 L or 80 ml
Explanation:
Use the equation V/t = V/t.
.04L / 150K = V / 300K
.04 / 150 * 300 = V

What is the pH of a .00034 M of HCl solution?
3.5
5.3
3.0
5.0
Answer:
pH = 3.5
Explanation:
HCl is a strong acid, so we can use this little formula to find the pH of the solution:
pH = -log[H3O+]
(where H3O+ is the strong acid, HCl)
So we just plug in the molarity for the concentration of the acid...
pH = -log(0.00034)
Solve.
pH = 3.468521083
And apply sig. figs....
pH = 3.5

Which of the following is common to both nuclear fusion and nuclear fission? PLZ I NEED ANSWER quickly
1.The fuel must be in the plasma state
2.A chain reaction is needed to start the reaction
3.Matter is converted into energy
4.Temperatures over one million degrees Celsius are needed for the reaction to occur
Answer:
I think number4.Nuclear fusion reaction is not possible in earth
Nuclear fusion and nuclear fission both have common to temperatures over one million degrees Celsius are needed for the reaction to occur. Therefore, option 4 is correct.
What is nuclear fusion ?A reaction known as nuclear fusion occurs when two or more atomic nuclei fuse to create new atomic and subatomic particles. Energy is released or absorbed depending on how much mass there is between the reactants and products.
Nuclear reactions that involve fusion and fission both yield enormous quantities of energy that can be used to generate power.
The two heavy isotopes of hydrogen, deuterium and tritium, are the primary fuels used in nuclear fusion. Only 0.0153% of natural hydrogen is deuterium, which may be easily and cheaply produced from seawater. Lithium, which is also widely distributed in nature, can be used to create tritium.
Thus, option 4 is correct.

16. What do you mean by 60 watt written on electric
bulb. Write electronic configuration of calcium by
sub-shell method.
Answer:
Explanation:
If it is said that an electric bulb contains 60 watts, that implies that the electric bulb will have to consume a required amount of energy of about 60 joules in a second.
Mathematically:
Power rating = Energy consumed ÷ time
The electronic configuration typically implies the arrangement of electrons in atomic orbitals. The electronic configuration of Calcium (Ca) in it subshell method is:
[tex]\mathbf{Ca (20) = 1s^2 2s^2 2p^6 3s^2 3p^6 4s^2 }[/tex]
If the temperature of 15 grams of water changes from 21C to 24C, how many joules of heat were involved? Show work
Answer:
189 Joules
Explanation:
Applying,
Q = cm(t₂-t₁)............. equation 1
Where Q = Heat, c = specific heat capacity of water, m = mass of water, t₁ = Initial Temperature, t₂ = Final temperature.
From the question,
Given: m = 15 grams = 0.015 kg, t₁ = 21 °C, t₂ = 24 °C
Constant: c = 4200J/kg.°C
Substitute these values into equation 1
Q = 0.015×4200×(24-21)
Q = 0.015×4200×3
Q = 189 Joules

K + Br2 → KBr
Identify a covalently bonded molecule in the reaction above that is a
REACTANT.
Answer: A covalently bonded molecule in the reaction
[tex]K + Br_{2} \rightarrow KBr[/tex] is [tex]Br_{2}[/tex].
Explanation:
A bond formed by sharing of electrons between two or atoms is called a covalent bond.
For example, bromine is a group 17 element and it has 7 valence electrons. It needs one more electron to complete its octet.
So, when one bromine atom chemically combines with another bromine atom then sharing of electrons takes place which leads to the formation of [tex]Br_{2}[/tex] molecule.
Hence, in the equation [tex]K + Br_{2} \rightarrow KBr[/tex]; [tex]Br_{2}[/tex] reactant is a covalently bonded molecule. A covlent bond is formed by two or more non-metal atoms that chemically combine together.
In a chemical equation, reactants are written on the left side and products are written on right side.
Thus, we can conclude that a covalently bonded molecule in the reaction
[tex]K + Br_{2} \rightarrow KBr[/tex] is [tex]Br_{2}[/tex].
