Imagine that you have 100g of water.

You start dissolving KNO3 in the water and you find that after you've dissolved about 55 g of KNO3, you can't dissolve any more; it just sinks to the bottom.

Approximately what is the temperature of the water?

Round your answer to the nearest whole number and submit the number only; no units.

Answer:

1) theory

2) law

3) hypothesis

Explanation:

edge 2021

A scientific hypothesis is a proposition that can be determined by experiments. If the gas container is heated, then the pressure inside will increase as shown by the hypothesis.

A scientific theory is a statement that has been tested by a thorough experiment and by following the experimental procedure to evaluate the results. The increase in temperature increases pressure because particle moves rapidly shown in theory.

A scientific law is a statement that is proven true by repeated experiments. As the temperature of the gas increases the pressure also increases showing the law of the ideal gas equation.

Therefore, scientific theory, law, and hypothesis are different.

Answer: 1) 1.6 moles of HCl

2) 7.0 moles of HCl

3) 2.4 moles of hydrogen

4) 0.96 moles of HCl

Explanation:

The balanced chemical equation is:

[tex]Zn+2HCl\rightarrow ZnCl_2+H_2[/tex]  

According to stoichiometry :

1 mole of [tex]Zn[/tex] require = 2 moles of [tex]HCl[/tex]

0.8 moles of [tex]Zn[/tex] will require=[tex]\frac{2}{1}\times 0.8=1.6moles[/tex]  of [tex]HCl[/tex]

3.5 moles of [tex]Zn[/tex] will require=[tex]\frac{2}{1}\times 3.5=7.0moles[/tex]  of [tex]HCl[/tex]

According to stoichiometry :

2 moles of [tex]HCl[/tex] produce = 1 mole of [tex]H_2[/tex]

4.8 moles of [tex]HCl[/tex] will require=[tex]\frac{1}{2}\times 4.8=2.4moles[/tex]  of [tex]H_2[/tex]

According to stoichiometry :

1 mole of [tex]ZnCl_2[/tex] are produced by = 2 moles of [tex]HCl[/tex]

0.48 moles of [tex]ZnCl_2[/tex] are produced by =[tex]\frac{2}{1}\times 0.48=0.96moles[/tex]  of [tex]HCl[/tex]

Explanation:

Answer:

The original volume of the gas is 0.001 mL

Explanation:

This easy excersise can be solved by the law for gases, about pressure and volume; the volume of a gas is inversely proportional to the pressure it exerts.

We can propose the rule by this formula:

P₁  / V₁ = P₂ / V₂

We replace data given: 1.50 atm / V₁ = 0.50 atm / 750 mL

As the rule says, that volume is inversely proportional, and the pressure was decreased, volume must be lower than 750 mL.

1.5atm / (0.5 atm / 750mL) = V₁

V₁ = 0.001 mL

Answer: The distribution of natural resources depends upon many physical factors like land, climate and altitude. The distribution of resources is unequal because these factors differ from place to place on this earth.

Many physical factors, such as land, climate, and altitude, influence the distribution of natural resources. Because these factors differ from place to place on this planet, the distribution of resources is unequal.

The Earth's surface is defined as the part of the water or land that comes into contact with the air above it. The surface is the part of the Earth with which we interact. The crust is the rock layer that surrounds the Earth's mantle. The crust encircles the entire planet, including the ocean floor.

The crust is the planet's surface, where we live; it's actually a very thin layer, only 70 kilometers thick at its thickest point.

Petroleum is formed by the same geological process that creates sedimentary rock. The geological processes that create rocks and natural resources such as granite and copper do not occur everywhere on Earth and take a long time to form. This explains why granite and copper aren't found everywhere on the planet.

Thus, Because these factors differ from place to place on this planet, the distribution of resources is unequal.

The number of grams that are needed to produce 1 mole on ammonia is to be considered as the 1.52 g Hz.

Here we begins the moles of ammonia for production after this it convert the number of moles of h2 for getting one mole of ammonia and then finally convert into grams

So it be like

[tex]= 1\ mol NH_3 \frac{3H_2}{2NH_3}\frac{1.01g }{1\ mol H_2}[/tex]
