This type of energy would be called reaction energy.
Answer:
Carbon
Explanation:
The way to identify an element is by looking at the number of protons the atom has. Every element has its own atomic number. This atom has 6 protons. If you look at the periodic table, you can see that the atom with the atomic number of 6 is carbon.
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.

#SPJ1
Answer:
Explanation:
1.
Given parameters:
Number of moles of CaO = 0.22moles
Unknown:
Mass of CaO = ?
Solution:
Mass, number of moles and molar mass are related using the expression below;
Mass = number of moles x molar mass
Molar mass of CaO = 40 + 16 = 56g/mol
Insert the parameters and solve;
Mass = 0.22 x 56 = 12.32g
2
Given parameters:
Number of moles of NaCl = 0.83moles
Unknown:
mass of NaCl = ?
Solution:
Also,
Mass = number of moles x molar mass
Molar mass of NaCl = 23 + 35.5 = 58.5g/mol
Now insert the parameters and solve;
mass = 0.83 x 58.5
mass = 48.6g
3.
Given parameters:
Number of moles of H₂SO₄ = 0.5moles
Unknown:
mass of H₂SO₄ = ?
Solution:
Mass = number of moles x molar mass
Molar mass of H₂SO₄ = 2(1) + 32 + 4(16) = 98g/mol
Insert the parameters and solve;
Mass = 0.5 x 98 = 49g
Answer:
the sodium nitrate in this investigation is
a) the solute
b) undergoing chemical change
<h3>
Explanation:</h3>
generally, solute is the substance which is added in solvent.
The substance which is taken in relatively more volume is the solvent.
so, here sodium nitrate (NaNO₃) is the solute which is dissolved in water (H₂O) , which is solvent.
The reaction between them is :
NaNO₃ + H₂O ⇒ Na⁺ (aq) + NO₃⁻ (aq) ; (aq) denotes aqueous;
so, here sodium nitrate undergoes chemical change into aqueous sodium ions(Na⁺) and aqueous nitrate ions(NO₃⁻).
