Answer:
the dividend yield is 4%
Explanation:
The computation of the dividend yield is as follows:
Dividend yield = Dividend per share ÷ current share price per share
= ($0.20 × 4 quarters) ÷ $20
= $0.80 ÷ $0.20
= 4%
hence, the dividend yield is 4%
The same is determined by applying the above formula
I'm assuming this refers to nuclear fission, which is in fact used to create heat, causing steam to spin turbines.
In which case, Uranium atoms are split by absorbing neutrons inside the reactor of a nuclear power station.
2 H₂O (l) → 2 H₂ (g) + O₂ (g)
Molar mass water = 1.01 x 2 + 16.00 = 18.02 g/mol
Number of mol water decomposed = 28.7 g H₂O x [1 mol / 18.02g] = 1.59 mol H₂O
<span>From the balanced equation 2 mol H₂O decomposes to 2 mol H₂ and 1 mol O₂ </span>
so the mole ratio water : oxygen = 2 : 1
and number of mol O₂ produced = ½ x 1.59 = 0.796 mol O₂
The ideal gas law is PV = nRT
so V = nRT/P
P = 0.986 atm
V = ?
n = 0.796
R = 0.0821 L atm K⁻¹ mol⁻¹
T = 294K
V = 0.796 x 0.0821 x 294 / 0.986
V = 19.5 L
<span>So 19.5 L O₂ gas are produced

Answer:
The concentration of the acid is 117.92 ± 0.03 mM.
Explanation:
In this problem, the concentration of NaOH and the volume used is given. The volume pipetted from the acid is also given. The concentration of the acid is given by:
CNaOH * VNaOH = Cacid * Vacid
158.32 * (18.76-0.14) = C acid * 25
C acid = 117.92 mM
The propagation of error for this problem, which is a multiplication is the concentration of the acid multiplied by the error divided by its respective value as shown in the equation below
error = 117.92 * 
The answer is 0.03 mM of uncertainty.
