The answer is 10%
The percent error is used to determine the precision of calculations. It can be expressed as:
where:
e - the percent error,
v - experimental value (measured value),
v₁ - theoretical value,
It is given:
e = ?
v = 88 calories
v₁ = 80 calories
Thus, the percent error is:
Tree sap is a viscoelastic polymer, which means it's not really a solid but a very viscous (sticky) fluid. It's fluidity ensures that it can properly <span>seal the spaces between the planks on wooden boats. Not only that, the pitch sap is hydrophobic - it is water resistant as well. </span>
When, it donates electons.
as for example take
NaCl ( sodium chloride)
it's an ionic compund,
that means it is formed by donating or gaining electrons
Na is writen first than, it must be electropositive i.e it has donated electons which made it positive and the clorine gains electron so it's electronegative.
Na is positive because
as we know it's atomic number is 11 that means it has 11 protons and 11 electrons
now, when it donate electon it has, greater number of protons whose change is +ve so the atom becomes overall positively charged ion or cation.
and something same happens in clorine and because it gains one electron and the number of electrons increase in it by 1 whise charge is -ve so, the atom becomes negatively charged ion or anion which has a -1 charge.
Sodium mn2 and po4 makes sodium
Answer:
The wavelength of the given electromagnetic radiation is 3.25 m.
Explanation:
We know that,
Frequency (f) = c / λ;
where,
c - speed of light = 
λ - wavelength of the radiation.
Given,
f = 
,
From the above formula,
λ =
λ = 
λ = 3.25m;
Therefore,
Wavelength of the given radiation = 3.25 m
