Because it can occur very rapidly and without conscious control.

Answer:

a coiled spring

Explanation:

Molarity as Stoikiometri

Equatuions od Molarity :

M = m/Mr × 1000/V

Mr Lithium Dichromate (Li2CrO4)

= Ar Li (2) + Ar Cr + Ar O (4)

= 7 (2) + 52 + 16 (4)

= 14 + 52 + 64

= 130 g/mol

Molarity

= m/Mr × 1000/V

= 19.5 g/130 g/mol × 1000/95 mL

= 0.15 mol × 10.53 /L

= 1.5795 mol/L

So, the molarity of the solution is 1.5795 mol/L

Think of it like theory and physics.

A theory is an idea that needs to be tested.

Scientific law is something that cant be proven wrong.

Answer:

The Sun looks bigger than other stars because its more closer to the earth than the stars.the farther anything is distant from us the tinier it will look

Explanation:

plz mark brainliest if thats ok|?

Answer:

1) Convert percent (m/V) to molarity

percent (m/V)=1.15 grams/100ml=1.15 g/0.1L=11.5g/L

molarity of KBr=mol/L=g/L *(1mol/molecular weight of KBr)=(11.5g/L) * (1mol/119.0g/mol)=0.0966 mol/L=0.0966M

2) calculation of osmol from mol

In solution, KBr dissociates into two ions K+ and Br- so there are 2 osmol of KBr per mol

3) calculation of osmolarity=molarity*2=0.0966*2=0.193 Osm or Osmolar

Answer:

1. A map is two dimensional, while a globe is three dimensional

2. A globe is a scaled down representation of the entire Planet Earth. A map can represent an area of any size.

Explanation:

1. A map is usually a sheet of rectangular paper that is a flattened image of an area as seen from the top. A globe on the other hand is a sphere which is a 3D shape.

2. Earth is in the shape of a sphere, so Globes are a smaller representation of the planet. A map can be for a city, state, country, or the world.

Answer:

That would be 2.51293615

Explanation:

1 liter is equal to 0.264172 gallons.

What you would need to do is, multiply the total number of liters, which in this case is 9.5125, by 0.264172.

9.5125 x 0.264172 gets you 2.51293665.

Answer:

4.37*10^24 atoms of K

Explanation:

1 mol=6.022*10^23 atoms (Avogadro's number)

To convert from mols to atoms multiply the mols of K by Avogadro's number.

7.25 mol K * 6.022*10^23 atoms = 4.36595*10^24 atoms

The elements should be label as follows yellow = OH, blue = Fe, green = Ba, red = Cl

The mix between aqueous barium hydroxide and aqueous iron chloride leads to barium chloride and iron hydroxide. This reaction is shown below:

Moreover, in these products, the iron hydroxide will form a solid substance that precipitates in the bottom of the container, while the barium chloride is more likely to maintain its liquid state.

According to this, the substance in the bottom is the iron hydroxide or Fe (OH)2, and in this, the yellow dots represent the Hydroxide or OH, while the blue dots are the Iron considering there in iron hydroxide there are two molecules of OH for each molecule of iron.

On the other hand, at the top, there is the barium chloride or BaCl2. This means the green dots are the Barium and the red ones are the Chlorine as there should be more Chlorine particles than Barium ones

Answer: Surface tension has a more complicated effect on capillary pressure: on the one hand, capillary pressure is directly proportional to surface tension. High surface tension liquids, on the other hand, typically have higher contact angles, which lowers capillary pressure.

Answer:

57.6g

Explanation:

So, if in one mole of water, 16 g of oxygen atom is present. Then, in 3.6 moles of water, the mass of oxygen present will be 3.6×16=57.6g. Therefore, the amount of oxygen present in 3.6 g water is option (B)- 57.6 g.

a gas does not have a fixed shape because there is nothing to hold its shape

Answer: I would say the last one only

Explanation:

Cuz Gases have the following characteristics:

Answer:

Yes, water can stay liquid below zero degrees Celsius. There are a few ways in which this can happen. The freezing point of water drops below zero degrees Celsius as you apply pressure. When we apply pressure to a liquid, we force the molecules to get closer together.
