Mnenie [13.5K]

Answer:

The density of a potato is $\dfrac{M}{V'}$

Explanation:

Given that,

A potato that is too large to fit into a graduated cylinder.

Let us consider the mass of potato is M and volume of entire potato is V'.

The volume of water is V.

We know that,

Density :

The density is equal to the mass divided by volume.

In mathematically,

$\rho=\dfrac{m}{V}$

Where, m = mass

V = volume

We need to calculate the volume of potato

Using formula for volume

$V'=V''-V$

Where, V' = volume of potato

V''=Volume of combine water and potato

V = volume of water

We need to determine the density of a potato

Using formula of density

$Density\ of\ potato=\dfrac{Mass\ of\ potato}{volume\ of\ entire\ potato}$

Put the value into the formula

$\rho=\dfrac{M}{V'}$

Hence, The density of a potato is $\dfrac{M}{V'}$

The chemical reaction shown above takes place in a closed system. What is true about the system while the reaction occurs? A. Th

Ede4ka [16]

Answer: In a chemical reaction, the total mass of the particles in the system stays the same

Explanation:

Law of conservation of mass states that mass can neither be created nor be destroyed but it can only be transformed from one form to another form.

This also means that total mass on the reactant side must be equal to the total mass on the product side in a chemical reaction.

Every balanced chemical reaction follows law of conservation of mass.

For Example: Formation of water molecule

$2H_2+O_2\rightarrow 2H_2O$

Total mass on reactant side = $[2(2\times 1)+(2\times 16)]=36g/mol$

Total mass on product side = $[2((2\times 1)+16)]=36g/mol$

Hence, in a chemical reaction, the total mass of the particles in the system stays the same

Osmosis and diffusion are related processes that display similarities. Both osmosis and diffusion equalize the concentration of two solutions. Both diffusion and osmosis are passive transport processes, which means they do not require any input of extra energy to occur. In both diffusion and osmosis, particles move from an area of higher concentration to one of lower concentration. Osmosis and facilitated diffusion both account for movement of molecules from a region of high concentration to a region of low concentration.

Predict the reactivity of silicon in water relative to that of sodium, magnesium, and aluminium. Explain your answer. How does t

Inessa [10]

Answer:

See explanation

Explanation:

The reactivity of metals has a lot to do with their position in the electrochemical series. However, it is also known that metallic character decreases across the period. This implies that as we move from left to right along the periodic table. Sodium, magnesium, aluminum and silicon continues to decrease in metallic character. As a matter of fact, silicon is a metalloid and not a pure metal.

Sodium reacts with cold water to give a vigorous reaction,magnesium and aluminium reacts with steam at red heat.

Silicon does not react with water, even as steam, under normal conditions.
