110) Lake Michigan holds 1.3 x 10's gallons of water. If just Chicago removed water from the lake and it

1 answer:

5 0

You omitted what it was raised to the power in 1.3 x 10's gallons of water, so i will put it up as 1.3 x 10^15 gallons of water and solve with it

Answer:1,083,333 days

Explanation:

Total amount of water held by lake Michigan= 1.3 x 10^15 gallons of water

Amount of water Chicago uses per day =Chicago uses 1.2 x 10^9 gallons of water /day

Therefore,

Number of days water would last if it doesnt rain = Total gallons provided by lake Michigan/ Total gallons consumed per day

=1.3 x 10^15 gallons of water/ 1.2 x 10^9 gallons of water /day

= 1,083,333 days

The destructive force of waves is not felt while they are out at sea, in the open ocean, but it is felt when they do what?

PIT_PIT [208]

Answer: Come Onshore

Explanation:

Sea waves are harmless when present at Sea. However, it becomes DESTRUCTIVE as it travels to the land surface.

Its effects include the sweeping off (erosion) of features, BENEFICIAL soil organisms and the transport of sand and sediment along coastal areas which might include farms, residential houses etc.

Thus, the effects of Sea waves ONSHORE affects the following: agricultural activities

Domestic activities

Environmental balance etc.

n an experiment, 39.26 mL of 0.1062 M NaOH solution was required to titrate 37.54 mL of \ v unknown acetic acid solution to a ph

olasank [31]

Answer:

Molarity: 0.111M

% (w/w): 0.666

Explanation:

The reaction of NaOH with acetic acid (CH₃COOH) is:

NaOH + CH₃COOH → CH₃COO⁻Na⁺ + H₂O

where 1 mole of NaOH reacts per mole of acetic acid producing 1 mole of water and 1 mole of sodium acetate.

As 39.26mL ≡ 0.03926L of 0.1062M are required to titrate the solution of acetic acid. Moles are:

0.03926L × (0.1062mol / L) = 4.169x10⁻³ moles of NaOH. As 1 mole of NaOH reacts per mole of acetic acid:

4.169x10⁻³ moles of CH₃COOH.

Molarity is defined as ratio between moles of substance and volume of solution in liters. Thus, molarity of acetic acid solution is:

4.169x10⁻³ moles of CH₃COOH / 0.03754L = 0.111M

As molar mass of acetic acid is 60g/mol, 4.169x10⁻³ moles weights:

4.169x10⁻³ moles × (60g / mol) = 0.2501 g of acetic acid

Now, assuming density of solution as 1.00g/mL, 37.54mL weights 37.54g.

Thus, percent by weight is:

0.2501g CH₃COOH / 37.54g × 100 = 0.666% (w/w)

Nitrogen and oxygen form an extensive series of oxides with the general formula NxOy. One of them is a blue solid that comes apa

Marizza181 [45]

Work out the number of moles in

100.00 grams of the oxide.

For nitrogen: The atomic mass of N is 14.0067, and we have 36.84 g N:

36.84 g N14.0067 g N/mol N=2.630 mol N

For oxygen: The atomic mass of O is

15.9994, and we have

100.00−36.84=63.16 g O:

63.16 g N 15.9994 g N/mol N=3.948 mol N

Now the ratio 3.958 2.630 is very close to

1.5=32

. So we conclude that the gas has three moles

O to two moles N making the empirical formula

N2O3.

What happens to the particles in matter when hear energy is added to them

Ipatiy [6.2K]

There are two possible situations.
1) If a phase change is not occurring, then the heat added contributes to increased translational energy of the particles. What that means is the particles move/vibrate faster.
2) If a phase change is occurring, then the heat added contributes to the breaking of bonds or intermolecular forces (depending on the chemical nature of the matter you're dealing with).
