What is the definition of law of chemical combination??

### Answers

Answer:

In simple terms, this law states that matter can neither be created nor destroyed. In other words, the total mass, that is, the sum of mass of reacting mixture and the products formed remains constant.

HOPE IT'S HELPFUL!

The sun of mass of reacting mixture and products formed; a mass that remains constantly

the distance from earth to the moon is approximately 3.84x10^5 km. how long would it take a radio wave with the frequency 7.25x10^5 Hz to travel from Earth to the moon

### Answers

The time that would  take   a radio wave with the frequency of 7.25 x 10^5 Hz  to travel from  earth to the moon is    1.28  sec

Calculation

Time =  distance / speed

distance =  3.84 x 10 ^5 km

convert  Km to m

1 Km= 1000 m

3.84 x10^5km= ? m

by cross multiplication

= (3.84 x 10^5 km x 1000 m) / 1 km = 3.84 x 10 ^8 m

Speed  of light=  3.0  x 10^8 m/s

therefore time =  3.84  x10^8 m / 3.0  x10^8 m/s =  1.28  sec

2. A volume is measured experimentally as 4.26 mL. What is the percentage error, given that the correct value is 4.15 mL?
Measurements and Calculation

### Answers

Answer:

0.73% error

Explanation:

Take the absolute value of the measured value minus the actual value and divive it by the actual value. Then multiply it by 100%.

I 4.26-4.15 I = 0.11/4.15 = 0.007333 x100% = 0.73%

Which atomic model proposed that electrons move in specific orbits around the nucleus of an atom? Dalton’s atomic model
Thomson’s atomic model
Rutherford’s atomic model
Bohr’s atomic model
quantum atomic model

### Answers

The atomic model that proposed that electrons move in specific orbits around the nucleus of an atom was Bohr's atomic model.

Explanation:

Bohr's greatest contribution to trendy physics was the atomic model. Nuclear physicist was the primary to get that electrons travel in separate orbits round the nucleus which the quantity of electrons within the outer orbit determines the properties of a part.

The atomic model that proposed that electrons move in specific orbits around the nucleus of an atom was Bohr's atomic model. The correct answer is the 4th choice given.

Why do the vinegar and oil in a salad dressing separate into layers if left standing for too long?

### Answers

Because they  have different densities which cause them to separate .
In the case of oil and vinegar, the vinegar is polar and more dense than the oil, so it settles on the bottom of the container. The oil is nonpolar and less dense, so it doesn't dissolve in the vinegar, and it floats on top.

Be sure to answer all parts. Calculate the number of g of O, that will react with 9.98 mol of CzHg. Enter your answer in scientific notation. The balanced equation is: C3H2(g) + 502(g) → 3C02(g) + 4H2O(g). * 10 (select) A go,

### Answers

Answer: The mass of oxygen reacted is

Explanation:

We are given:

Moles of propane = 9.98 mol

For the given chemical equation:

By Stoichiometry of the reaction:

1 mole of propane reacts with 5 moles of oxygen.

So, 9.98 moles of propane will react with = of oxygen.

To calculate the mass of carbon dioxide, we use the equation:

Moles of oxygen = 49.9 moles

Molar mass of oxygen gas = 32 g/mol

Putting values in above equation:

Hence, the mass of oxygen reacted is
