Theories are not as well proven as scientific laws.
O Scientific laws explain natural phenomena while theories are just guesses.

Answers

Answer:

pretty sure its Scientific laws are statements about observed experimental facts, while theories are explanations of natural phenomena.

The statement that correctly explains the difference between a theory and a scientific law is as follows:

Scientific laws are statements about observed experimental facts, while theories are explanations of natural phenomena.

Thus, the correct option is B.

What is Scientific theory?

A Scientific theory may be defined as a well-explained fact that is significantly associated with the natural world that has been constructed through the utilization of the scientific method, and which brings together many facts and hypotheses.

A Scientific theory is based on observation. It is proven but still testable in nature in order to derive evidence. It generally does not possess mathematical statements and deductions. Theories are explained on nature as well as natural phenomena.

Scientific law is based on unalterable facts or those facts that remain constant. It is proven as well as contains evidence to support the claim. It definitely possesses mathematical statements and deductions.

Therefore, the correct option for this question is B.

Some chemical reactants are listed in the table below. Complete the table by filling in the oxidation state of the highlighted atom.

Answers

Answer:

1. Cu = +2

2. O = – 2

3. C = +2

4. N = 0

Explanation:

Note:

A. The oxidation state of oxygen is always – 2 except in peroxides where it is – 1.

B. The oxidation state of Hydrogen is always +1 except in metallic hydrides where it is – 1.

Now let us solve the question given above.

1. CuO = 0 (ground state)

Cu + O = 0

O = – 2

Cu + (– 2) = 0

Cu – 2 = 0

Collect like terms

Cu = 0 + 2

Cu = +2

2. H2O = 0 (ground state)

2H + O = 0

H = +1

2(1) + O = 0

2 + O = 0

Collect like terms

O = 0 – 2

O = – 2

3. CO = 0 (ground state)

C + O = 0

O = – 2

C + (– 2) = 0

C – 2 = 0

Collect like terms

C = 0 + 2

C = +2

4. N2 = 0 (ground state)

2N = 0

Divide both side by 2

N = 0/2

N = 0

Identify the substance oxidized and the substance reduced in the following chemical equation:zn(s)+AgNO3(aq)=Zn(No3)2+2Ag(a)​

Answers

Answer:

Explanation:

zn is oxidized because its oxidation number is increased from zero in zn to +2 in zn(No3)2

Ag is reduced because its oxidation number is reduced from +1 in AgNo3 to zero in Ag

oxidation number of zn(s) is zero while the oxidation number of zn in zn(No3)2  is

zn(No3)2=x+(5*2)+(-2*6)=x+10-12=x-2

x-2+2=2

x=2

the oxidation of Ag in AgNo3

AgNo3=x+5+(3*-2)=x+5-6=x-1

x-1+1=1

x=1 while the oxidation number of Ag is zero

so zinc is oxidized and silver (Ag) is reduced

Describe how molecular motion and distance between molecules change as ice is heated to become a liquid and then a gas

Answers

Answer:

Described in the explanation section

Explanation:

Ice is the solid phase of water and this phase, the water molecules usually have very little energy and therefore can't detach from each other. This is because the water molecules are closely packed together in a regular arrangement normally called lattice.

Now, when the ice is heated to become a liquid, the energy of the water molecules increases and thus some of them will have enough energy to overcome the intermolecular forces that had been keeping them closely packed in the ice phase. This will then make the water molecules to move further apart thereby forming liquid water.

Now, when the molecules are heated further, the liquid water will now turn into water vapor, which is the gas phase of water. The molecules in this gas phase will have more energy than in the liquid phase because the average distances between each of them will be much larger than the size of the molecules themselves.

density of the ring.
I

Answers

Answer:

The answer is

19.3 g/mL

Explanation:

The density of a substance can be found by using the formula

[tex]Density = \frac{mass}{volume} [/tex]

From the question

mass = 67 g

Volume of ring = new volume of water - original volume of water

Volume = 13.47 - 10 = 3.47 mL

Substitute the values into the above formula and solve

That's

[tex]Density = \frac{67}{3.47} \\ = 19.308357[/tex]

We have the final answer as

19.3 g/mL

The head of a pin is 1.5 × 10-3 m in diameter. If 1.136 × 107 atoms of oxygen can fit across the head of a pin, what is the atomic radius of oxygen?

Answers

About five million million hydrogen atoms could fit. Some factors would affect that number like the area of the head and the size of atoms (as well as attractions between atoms). Some atoms are larger than others.

If 1.136 × 10⁷ atoms of oxygen can fit across the head of a pin whose diameter is 1.5 × 10⁻³ m, the atomic radius of oxygen would be 6.60 × 10⁻¹¹ m.

The head of a pin is 1.5 × 10⁻³ m in diameter. If 1.136 × 10⁷ atoms of oxygen can fit across the head of a pin, the diameter of each oxygen atom would be:

[tex]\frac{1.5 \times 10^{-3}m }{1.136 \times 10^{7}atom} = 1.32 \times 10^{-10}m/atom[/tex]

The atomic radius of oxygen would be half of its diameter.

[tex]\frac{1.32 \times 10^{-10} m}{2} = 6.60 \times 10^{-11} m[/tex]

If 1.136 × 10⁷ atoms of oxygen can fit across the head of a pin whose diameter is 1.5 × 10⁻³ m, the atomic radius of oxygen would be 6.60 × 10⁻¹¹ m.

What is the percentage by mass of a solution with 30.0g salt dissolved in water to make 650.0g 0f solution?
Please help​

Answers

Answer:

The percentage by mass of a solution with 30.0g salt dissolved in water to make 650.0g 0f solution is 4.61 %

Explanation:

The mass percentage of a solution is a measure of concentration that indicates the number of grams of solute that there are per 100 grams of solution.

The percent by mass is calculated as the mass of a component divided by the total mass of the mixture, multiplied by 100 to give a percentage.

[tex]percentage by mass=\frac{solute mass}{solution mass} *100[/tex]

In this case:

solute mass: 30 gsolution mass: 650 g

Replacing in the definition of percent by mass:

[tex]percentage by mass=\frac{30 g}{650 g} *100[/tex]

Solving:

percent by mass= 4.61 %

The percentage by mass of a solution with 30.0g salt dissolved in water to make 650.0g 0f solution is 4.61 %
