A chemist prepares a solution of iron(II) bromide (FeBr2) by measuring out 46. g of iron(II) bromide into a 400. mL volumetric flask
and filling the flask to the mark with water.
Calculate the concentration in mol/L of the chemist's iron(II) bromide solution. Round your answer to 2 significant digits.
Answers
Solution
Given mass of FeBr2 = 85.5 g
Molar mass of FeBr2 = 215.65
No. of Moles of FeBr2 = Given Mass / Molar mass = 85.5 / 215.65
No. of Moles = 0.3964
Given Volume is 450 mL i.e. 0.450 L
Now Concentration = 0.3964/0.450
Hence Concentration = 0.881 mol/L

If a water fountain has an average flow rate of 0.64 gallons per minute, how many
seconds does it take to dispense 842.75 mL. (Hint: 3.78541 L = 1 gal, 60 s = 1 min)
Answers
The time taken for the water fountain to dispense 842.75 mL of water is 20.625 seconds
What is time?Time can be defined as the measure of past, present or future events.
To calculate the time taken to dispense 842.75 mL of water, we use the formula below.
Formula:
F = V/t................ Equation 1Where:
F = Average flow rate of the fountainV = Volume of the watert = time.Make t the subject of the equation.
t = V/F................ Equation 2From the question,
Given:
F = 0.64 gallons per minutesV = 842.75 mL = (842.75/1000)/(3.78541) gal = 0.22 gal.Substitute these values into equation 2
t = 0.22/0.64t = 0.34375 minutes.t = (0.34375×60) = 20.625 seconds.Hence, The time taken for the water fountain to dispense 842.75 mL of water, is 20.625 seconds.

Aspirin, C9H8O4, slowly decomposes at room temperature by reacting with water in the atmosphere to produce acetic acid, HC2H3O2, and 2-hydroxybenzoic acid, C7H6O3 (this is why old bottles of aspirin often smell like vinegar):
Answers
Based on the chemical reactivity, the decomposition of aspirin in the presence of water produces acetic acid and 2-hydroxybenzoic acid.
What is a decomposition reaction?A decomposition reaction is a reaction in which a large substance is broken down into smaller substances.
Example of a decomposition reaction is the decomposition of aspirin to produce acetic acid.
Aspirin (C9H8O4) slowly decomposes at room temperature by reacting with water in the atmosphere to produce acetic acid, HC2H3O2, and 2-hydroxybenzoic acid, C7H6O3.
The equation of the reaction is given below:
C9H8O4 + H2O -----> HC2H3O2 + C7H6O3Therefore, the decomposition of aspirin produces acetic acid and 2-hydroxybenzoic acid.

What is the mass of an object that has a volume of 12cm3 and a density of 1.5g/cm3
Answers
Answer:
18g
Explanation:
D=m/v
D= Density (g/mL) OR (g/cm^3)
m= mass (g)
v= volume (mL)
Use the Desity formula to find the mass by rearranging the formula so that m = D*v
Simply multiply the density by the volume
1.5*12 =18g
because it is the mass you’re looking for.
Which statement correctly describes a reaction in dynamic equilibrium?
o At dynamic equilibrium, the reactions stop and the amounts of reactants and products do not change.
o At dynamic equilibrium, the reactions continue but the amounts of reactants and products do not change.
o At dynamic equilibrium, the reactions stop but the amounts of reactants and products are changing.
o At dynamic equilibrium, the reactions continue and the amounts of reactants and products are changing.
Answers
Answer:
"At dynamic equilibrium the reactions continue but the amounts of reactants and products do not change." would be the correct description
Explanation:
Dynamic equilibrium occurs when the rates of change and concentration are the same, so the reaction still takes place, but the amounts of reactants and products stay the same without any change.
According to chemical equilibrium, the statement which correctly describes dynamic equilibrium is that at dynamic equilibrium, the reactions continue but the amounts of reactants and products do not change.
What is chemical equilibrium?Chemical equilibrium is defined as the condition which arises during the course of a reversible chemical reaction with no net change in amount of reactants and products.A reversible chemical reaction is the one wherein the products as soon as they are formed react together to produce back the reactants.
At equilibrium, the two opposing reactions which take place take place at equal rates and there is no net change in amount of the substances which are involved in the chemical reaction.At equilibrium, the reaction is considered to be complete . Conditions which are required for equilibrium are given by quantitative formulation.
Factors which affect chemical equilibrium are change in concentration , change in pressure and temperature and presence of catalyst.

why are atoms so picky on who they bond with
Answers
Explanation:
Atoms are not really picky. They actually bond with other atoms to form an octect state. Let's take an example of an atom with, say, 2 valence electrons. This atom will have to bond with an atom which has 6 valence electrons to reach its octect state (6 + 2 = 8 =》 octect state is from L shell and above).

2. Barium compounds are chemically very similar to strontium compounds. Water-soluble
compounds of both are toxic, but to different degrees. An antidote for barium chloride
poisoning is to orally administer 30 grams of sodium sulfate in 250 mL of water. Explain the
chemical basis for this antidote.
Answers
The ability of sodium sulfate to act as an antidote to barium chloride poisoning is because displaces barium in barium chloride to form sodium chloride and insoluble harmless barium sulfate.
Why is a solution of sodium sulfate used as an antidote?The ability of sodium sulfate to act as an antidote to barium chloride poisoning is because of the reactivity of sodium.
Sodium is a more reactive metal than barium, so it displaces barium in barium chloride to form sodium chloride and insoluble harmless barium sulfate.
The equation of the reaction is given below:
BaCl2 + Na2SO4 ----> BaSO4 + NaClTherefore, the ability of sodium sulfate to act as an antidote to barium chloride poisoning is because displaces barium in barium chloride to form sodium chloride and insoluble harmless barium sulfate.

Are oceans like giant swimming pools are they connected
Answers
Answer and Explanation:
Oceans are like giant swimming pools for marine life. Not really for people though. One difference that most swimming pools tend to have chlorine in them. If not, then they have salt water similar to an ocean. The chemical substance chlorine is not good for marine life at all, and isn't really good for people either.
But instead of chlorine, oceans have types of bacteria that aren't good for people either, especially if ingested in high amounts. So, if you've ever accidentally swallowed sea water and felt a little sick to your stomach, this could be why. They are similar though because they both have water and a form of bacteria.
They are not connected in a way of cycling water with each-other, but they do have similarities and differences as I had mentioned before.

is NO2 an ionic or covalent bond? Will give brainliest for the correct answer
Answers

Covalent
Explanation:
hi, How are you?
NO2 is already polar, due to the fact that nitrogen shares a maximum of 3 electrons. Thus N makes two covalent bonds with one oxygen, one covalent and one dative with the other. And there's still a free electron left that causes the molecule to bend, forming an angle, and so the NO2 molecule is polar with an angle other than 180.
