A 150 mL sample of hydrochloric acid (HCl) completely reacted with 60. 0 mL of a 0. 100 M NaOH solution. The equation for the reaction is given below. HCl NaOH Right arrow. NaCl H2O What was the original concentration of the HCl solution? 0. 040 M 0. 25 M 1. 50 M 2. 50 M.
Answer:
The balanced chemical reaction is expressed as:
HCl + NaOH ---> NaCl + H2O
We are given the amount and the concentration of the sodium hydroxide reactant. This will be the starting point for the calculations.
0.100 mol NaOH/L solution (0.06 L solution) ( 1 mol HCl / 1 mol NaOH) = 0.006 mol HCl
Molarity = amount in moles / Volume of solution = 0.006 mol HCl/ 0.150 L
Molarity = 0.04 M

What are the components of a voltaic cell?
Answer:
• The anode is an electrode where oxidation occurs.
• The cathode is an electrode where reduction occurs.
• A salt bridge is a chamber of electrolytes necessary to complete the circuit in a voltaic cell.
• The oxidation and reduction reactions are separated into compartments called half-cells.
•The external circut is used to conduct the flow of electrons between the electrodes of the voltaic cell and usually includes a load.
• The load is the part of the circuit which utilizes the flow of electrons to perform some function.
Determine the empirical formulae of the compounds which contain:
9.39g P, 0.61 g H
The empirical formula of the compound containing 9.39 g of phosphorus and 0.61 g of Hydrogen is PH₂
Data obtained from the question Phosphorus (P) = 9.39 gHydrogen (H) = 0.61 gEmpirical formula =? How to determine the empirical formulaThe empirical formula of the compound can be obtained as follow:
Divide by their molar mass
P = 9.39 / 31 = 0.303
H = 0.61 / 1 = 0.61
Divide by the smallest
P = 0.303 / 0.303 = 1
H = 0.61 / 0.303 = 2
Thus, the empirical formula of the compound is PH₂

A mutation is a change in the DNA base sequence. What effect would this have on a protein?
Answer:
Consequently, once it encounters the mutation, the ribosome will read the mRNA sequence differently, which can result in the production of an entirely different sequence of amino acids in the growing polypeptide chain.
Explanation:
Answer:
A missense mutation is when the change of a single base pair causes the substitution of a different amino acid in the resulting protein. This amino acid substitution may have no effect, or it may render the protein nonfunctional.

What are two elements that will react similarly to Beryllium
(Be)? Explain how you know.
The two elements with properties most like beryllium are magnesium and aluminium.
Explanation;
Beryllium and magnesium are two adjacent alkaline earth metals. That means; both these chemical elements are in the same group (group 2), but in different periods, i.e., beryllium is in the 2nd period while magnesium is in the 3rd period.
A 52-kg woman has 7.2 x 10-mol of hemoglobin (molar mass =
64456 g/mol ) in
her blood. How many hemoglobin molecules is this?
There are 6.022 x 1023 molecules per mole (Avogadro's number). As there are 7.2 x 10-3 moles of hemoglobin, the number of hemoglobin molecules would be 6.022 x 1023 molecules/mole x 7.2 x 10-3 moles = 4.3 x 1021 molecules
A 52-kg woman has 7.2 x 10 mol of hemoglobin in her blood. The quantity of hemoglobin molecules is 4.3 x 10²¹ molecules.
What is hemoglobin?Red blood cells include the protein hemoglobin, which transports oxygen to your body's organs and tissues, and carbon dioxide from those tissues back to your lungs.
You have a low red blood cell count if a hemoglobin test finds that your hemoglobin level is lower than normal (anemia).
Molar mass of many compounds can be calculated by dividing the mass of the compound by the number of moles of the compound.
There are 6.022 x 1023 molecules per mole (Avogadro's number).
As there are 7.2 x 10⁻³ moles of hemoglobin, the number of hemoglobin molecules would be 6.022 x 10²³ molecules/mole x 7.2 x 10⁻³ moles = 4.3 x 1021 molecules.
Therefore, the number of hemoglobin molecules is 4.3 x 10²¹ molecules.

Took the Quick Check
Marcus and his brother always argue about who will walk the dog. Their father wants to find a random way of deciding who will do the job. He invented a game to help them decide. Each boy will have a bag with three colored blocks in it: one yellow, one green, and one white. Each night before dinner, each boy draws a block out of his bag. If the colors match, Marcus walks the dog. If the two colors do not match, his brother walks the dog. Marcus's father wants to be sure that the game is fair. a. Make a probability tree of all of the possible combinations of draws that Marcus and his brother could make. How many possibilities are there? b. What is the probability that the boys will draw matching blocks?
By studying the experiment, we will see that:
a) There are 9 possible outcomes (listed in the answer) all with the same probability.
b) The probability of drawing matching blocks is 1/3.
How to know if the game is fair?
The game is fair if and only if the two outcomes have the same probability.
Here the two outcomes that we care for are:
The colors match.The colors do not match.a) First, in each bag all the blocks have the same probability of being drawn, which is 1/3.
Then each combination will have the same probability, which is:
p = (1/3)*(1/3) = 1/9.
Now, the possible combinations of colors are given by the table:
Marcus Brother probability
yellow yellow 1/9
yellow green 1/9
yellow white 1/9
white yellow 1/9
white green 1/9
white white 1/9
green yellow 1/9
green green 1/9
green white 1/9
b) The probability that the boys draw matching blocks is given by the sum between the probabilities that they draw 2 yellow blocks, 2 green blocks, and 2 white blocks, this is:
P = 1/9 + 1/9 + 1/9 = 1/3.

Recent data indicates atmospheric carbon dioxide (CO2) levels are rising. What change in the carbon cycle has most likely caused this increase in atmospheric CO2?.
The atmospheric carbon dioxide has been increased due to the increased industrial gases and the greenhouse effects.
What is the carbon cycle?The carbon cycle has been given as the rotation of the carbon in the atmosphere in different forms. The carbon has been absorbed by plants and the degradation passed the carbon from the plants forms the transfer of carbon to the soil.
The increased activities such as industrial gases, greenhouse gases, and other effects resulted in the increased carbon in the atmosphere and thereby the interruption to the carbon cycle.

Which plate has the most countable
colonies? Use the CFU calculator to

can someone please help with this I hate it so much
The agar plate with the most countable colonies should be determined by using a colony forming unit (CFU) calculator.
What is a colony?
A colony can be defined as a group of visible mass of microorganisms such as bacteria, fungi, that originated (cultured) from a single-mother cell and are grown on a solid agar medium.
In order to determine the most countable colonies, we have to count the total number of colonies by using a hemacytometer and then use a colony forming unit (CFU) calculator to determine the cfu/mL.
Note: You should choose a dilution factor based on the total number of colonies contained in the agar plate.
Finally, input the correct dilution factor into the colony forming unit (CFU) calculator to determine which agar plate has the most countable colonies.
