Answer:

2.35 M

Explanation:

Molarity is mol/L of solution. We have to convert the g to mol and the mL to L. G to mol uses the molar mass of the compound. The molar mass of NaNO₃ is 85.00g/mol.

[tex]50.0gNaNO3*\frac{1molNaNO3}{85.00gNaNO3} = 0.588molNaNO3[/tex]

Then you have to convert mL to L.

[tex]250mL*\frac{1L}{1000mL} = 0.250L[/tex]

Now divide the mol by the L.

[tex]\frac{0.588mol NaNO3}{0.250L} = 2.352 M[/tex]

Round to the smallest number of significant figures = 2.35M

Answer:

Melted ionic compounds have freely moving ions while solid ionic compounds do not.

Explanation:

A melted ionic compound has freely moving ions where electrons can be   transfered because the elements of the ionic compounds have broken there bonds and have dissociated into their ions. Compared to a solid ionic compound where it's still in the crystal lattice and the elements will stick in place and the ions will not move because it's in a solid state and they haven't dissocated into their ions.

Answer:

The atmosphere and hydrosphere interact in water-related weather, this includes snowstorms, hurricanes, rainfall, and monsoons.

The question is incomplete, the complete question is;

The atmosphere and hydrosphere interact in which type of severe weather?

A. Hurricanes

B. Drought

C. Sinkholes

D. Wildfires

The atmosphere and hydrosphere interact in the severe weather called hurricanes.

A hurricane is defined as a cyclonic storm which forms over warm tropical waters and moves at about 74 miles per hour.

When hurricanes mostly move over dry water and causes large scale destruction of property. As hurricanes move, they create tornadoes.

Hurricanes are formed when moist air rises over water. A convection current is set up as the moist air is replaced by cooler air.

Answer:

Yes, Democritus's atomic theory was correct.

Explanation:

He thought the first part of his theory states that all matter is made of atoms, which are indivisible. The second part of the theory says all atoms of a given element are identical in mass and properties. The other scientists added onto his theory to show that he was correct, except Aristotle, he thought the world was made of the 4 elements: earth, wind, fire, water.

Answer:

All of these are properties of an alkali metal

Explanation:

Alkali metals are metals of group 1. These metals are known to react with water to form the corresponding alkali and liberate hydrogen gas.

They are all silvery in appearance hence they are shiny. They are so soft that they can easily be cut into pieces.

Answer:

Explanation:

The law of conservation of mass or principle of mass conservation states that for any system closed to all transfers of matter and energy, the mass of the system must remain constant over time, as the system's mass cannot change, so the quantity can neither be added nor be removed.

Answer:

The tectonic plates do not slowly drift over time because they are floating on a layer of liquid rock. They drift because they are sitting on a layer of solid rock (the upper mantle or "asthenosphere") that is weak and ductile enough that it can flow very slowly under heat convection, somewhat like a liquid.

Answer:

The answer is B

Explanation:

The wavelength of light is found to be 6.98  × 10^-8 m.

We know that light is an electromagnetic wave, the speed of an electromagnetic wave is commonly referred to as the speed of light which has a numerical value of 3 × 10^8 m/s.

Now;

c = λf

c = speed of light

λ = wavelength of light

f = frequency of light

But;

λ = c/f

λ =  3 × 10^8 m/s/ 4.3 X 10^15 Hz

λ = 6.98  × 10^-8 m

Answer:

the answer is D. The liquid is a mixture because it has a gas dissolved in a liquid.

Explanation:

i got it right 2020

The liquid is considered as a mixture because this liquid has a gas dissolved which comes out from it in the form of bubbles.

This liquid is considered as a mixture because the gas which is dissolved in it with a high pressure is now removed due to removal of pressure. We know that in mixture elements are mix together not bonded to each other so we can conclude that the liquid is a mixture because it has a gas dissolved in a liquid.
