<span>The cell would swell and burst, because the 20% salt solution is hypotonic with respect to the cell, causing a net movement of water into the cell. Example, water moves from the blood filtrate that will form urine. The same will do while pure water moved to seawater.</span>
They move through the membrane
Answer:
A combination reaction
Explanation:
The chemical reaction between ammonia and hydrochloric acid as shown below:
NH₃ + HCl → NH₄Cl
is a combination reaction.
In a combination reaction, two compounds combines together to give one compound.
A combination reaction is also known as a synthesis reaction.
A single product forms from tow or more reactants.
The driving force for such reaction is the large and negative heat of formation of the product.
Answer:
The cubic centimeter of boron is 2.
Explanation:
Density:
Density is equal to the mass of substance divided by its volume.
Units:
SI unit of density is Kg/m3.
Other units are given below,
g/cm3, g/mL , kg/L
Formula:
D=m/v
D= density
m=mass
V=volume
Symbol:
The symbol used for density is called rho. It is represented by ρ. However letter D can also be used to represent the density.
Given data:
mass of boron = 4.68 g
density of boron = 2.34 g/cm³
volume = ? (cm³)
Solution:
d = m/ v
v = m/d
v = 4.68 g/ 2.34 g /cm³
v = 2 cm³
