Many of the men may believe that they are fair and unbiased against women.

Many of the women may already believe that they face biases.

<h3>What is confirmation bias ?</h3>

The propensity to seek for, understand, favor, and remember information that supports or confirms one's preexisting opinions or values is known as confirmation bias. People exhibit this bias when they choose facts that support their opinions while rejecting those that contradict them or when they interpret ambiguous facts as supporting their preexisting beliefs. Although confirmation bias cannot be completely avoided, it can be controlled, for instance, by critical thinking education and training.

Confirmation bias has been linked to poor decisions in the scientific, organizational, financial, and political spheres. These biases can preserve or reinforce views in the face of contradictory data and contribute to overconfidence in personal opinions.

What is the [oh−] of a solution with ph 5.75
Gekata [30.6K]
[ H₃O⁺] = 10 ^- pH

[ H₃O⁺] = 10 ^ (- 5.75 )

[H₃O⁺] = 1.778x10⁻⁶ M

Kw = [ H₃O⁺] x [ OH⁻]

1x10⁻¹⁴ = 1.778x10⁻⁶ x [OH⁻]

[OH⁻] = 1x10⁻¹⁴ / 1.778x10⁻⁶

[OH⁻] = 5.62x10⁻⁹ M

hope this helps!

Suppose that you add 26.7 g of an unknown molecular compound to 0.250 kg of benzene, which has a K f of 5.12 oC/m. With the adde
nadya68 [22]

Answer: The molar mass of the unknown compound is 200 g/mol

Explanation:

Depression in freezing point is given by:

\Delta T_f=i\times K_f\times m

\Delta T_f=2.74^0C = Depression in freezing point

i= vant hoff factor = 1 (for molecular compound)

K_f = freezing point constant = 5.12^0C/m

m= molality

\Delta T_f=i\times K_f\times \frac{\text{mass of solute}}{\text{molar mass of solute}\times \text{weight of solvent in kg}}

Weight of solvent (benzene)= 0.250 kg  

Molar mass of solute = M g/mol

Mass of solute  = 26.7 g

2.74^0C=1\times 5.12\times \frac{26.7g}{Mg/mol\times 0.250kg}

M=200g/mol

Thus the molar mass of the unknown compound is 200 g/mol

If a gas occupies 733 mL at 10.0 °C, at what temperature will it occupy 950 mL, assuming the pressure of the gas remains constan
raketka [301]
This is an example of Charles’ Law problems, the basic equation is: V1/T1 = V2/T2. One vital thing to recall for all gas law problems is that the temperature must be in Kelvin (not Celsius). 
So our given is 10.0 C = 283 K. So 
V1/T1 = V2/T2 
733/283 = 950/T2 

T2 = 367 K

Using stoichiometry, determine the mass of powdered drink mix needed to make a 1.0 M solution of 100 mL from C12H22O11
ser-zykov [4K]

Answer:

\boxed{\text{3.4 g}}

Explanation:

Step 1. Calculate the moles of C₁₂H₂₂O₁₁

\text{n = 0.100 L} \times \dfrac{\text{1.0 mol}}{\text{1 L}}=\text{0.100 mol}

Step 2. Calculate the mass of C₁₂H₂₂O₁₁

\text{m = 0.100 mol} \times \dfrac{\text{342.30 g}}{\text{1 mol}} = \text{3.4 g}\\\\\text{The mass of sucrose needed is }\boxed{\textbf{3.4 g}}
