Answer:
17.04%
Explanation:
Actual Value = 173.1
Measured Value = 143.6
Percent error is obtained using the equation;
Percent error = (Measured - Actual) / Actual ]* 100
Percent error = [ (143.6 - 173.1) / 173.1 ] * 100
The absolute value of (Measured - Actual) is taken,
Percent Error = [29.5 / 173.1 ] * 100
Percent Error = 0.1704 * 100 = 17.04%
Answer is:
18 electrons.
<span>The principal quantum number (n) is one
of four quantum numbers which are assigned to each electron in an atom to
describe that electron's state.
The azimuthal quantum number (l) is a quantum number for
an atomic orbital that determines its orbital angular
momentum and describes the shape of the orbital, l = 0....n-1.</span>
<span>For n = 3, l = 0, 1, 2.</span>
<span>l = 0, s orbital with 2 electron.</span>
<span>l = 1, p orbitals with 6 electrons.</span>
<span>l = 2, d orbitals with 10 electrons.</span>
<span>2 + 6 + 10 = 18 electrons.</span>
Answer:
the layer of a liquid or gaseous heat-transfer agent between the free stream and a heat-exchange surface. In this layer the temperature of the heat-transfer agent changes from that of the wall to that of the free stream
Explanation:
The chemical reaction is balanced.
Explanation:
We have the following chemical reaction:
NaOH + HCl → NaCl + H₂O
It is a neutralization reaction between a base and an acid which produce a salt and water.
To balance the chemical reaction the number and type of atoms entering the reaction have to be equal to the number and type of atoms leaving the reaction. We do that to conserve the mass.
We do not need to add other stoechiometric coefficients because the reaction is already balanced.
1 Na atom is entering the reaction and 1 Na atom is leaving the reaction
1 Cl atom is entering the reaction and 1 Cl is leaving the reaction
1 O atom is entering the reaction and 1 O atom is leaving the reaction
2 H atoms are entering the reaction and 2 H atoms are leaving the reaction
