Answer:

The Bohr atomic model did not make correct predictions of large- sized atoms and provided sufficient information only for smaller atoms.

Scientists define work as the spending of energy.<br><br> True<br> False
Hoochie [10]
True; scientist define work as the spending of energy. This is because energy is required to move an object. For work to be done an object has to be moved from one point to another. Work is measured in joules similar to energy which is also measured in joules. Mathematically, work done is given by the product of force and distance moved by an object or a body.

A certain element exists as two different isotopes. 76.00% of its atoms have a mass of 35.00 amu and 24.00% of its atoms have a
ivanzaharov [21]

Answer:

35.48 uma

Explanation:

An isotope is when an element has equal numbers of protons but different mass value because it has different amount of neutrons.

To calculate the average atomic mass with the given data:

First change de percentages to fractional numbers, divide by 100.

Remember the sum of a percentage is equal to 100, but when you are adding the fractions the sum is equal to 1.

76/100 = 0.76

24/100 = 0.24

  %       fraction

76.00 0.76

24.00 0.24

total100.00 1.00

Now, multiply the mass with their corresponding fraction:

35(0.76) = 26.60

37(0.24) =  8.88

%      fraction amu amu

76.00 0.76 35         26.60

24.00 0.24 37         8.88

total100.00 1.00    average 35.48

Now you add the calculated mass to obtain the average atomic mass of the element.

And the value you will get is 35.48 amu.

I included an excel table so you can review it, I like to organize all the given data and the calculation in tables, also I think is easier to understand.

What volume in kiloliters will a sample of Bay water occupy if it has a volume of 125 ml?
Mamont248 [21]
This question is basically asking us to convert the volume from mL to kL.

We can do this by setting up a multiplication problem and cancelling out units:

\frac{125mL}{1}* \frac{1L}{1000mL} * \frac{1kL}{1000L}  =1.25* 10^{-4}kL

So now we know that the Bay water will occupy 1.25x10^-4 kL.

yeah

Explanation:

well, probably. they kicked me out of math class because I put a live chicken in the classroom and it pooped everywhere, so I had to clean it up and bring it back where I found it (which is the side of the road.)

A sample of nitrogen gas, (N2), occupies 45.0 mL at 27.00∘C and 80.0 kPa. What will be the pressure if the gas is cooled to −73.
maxonik [38]

Answer:

The new pressure is 53.3 kPa

Explanation:

This problem can be solved by this law. when the volume remains constant, pressure changes directly proportional as the Aboslute T° is modified.

T° increase → Pressure increase

T° decrease → Pressure decrease

In this case, temperature was really decreased. So the pressure must be lower.

P₁ / T₁ = P₂ / T₂

80 kPa / 300K =  P₂/200K

(80 kPa / 300K) . 200 K = P₂ →  53.3 kPa
