Avocados can be a healthy source of nutrients
I believe a food handler must use a test kit to determine the concentration of sanitizing solution. Sanitizing reduces pathogens on a surface to safe levels. The sanitizer are the agents that are used for sanitizing ; their effectiveness is determined by the factors such as concentration, contact time, pH, temperature, and also water hardness.
Fusion is joining two or more things together in resulting of the form of one thing
Melting is to make something liquefied by the use of heat
Answer:
81.26% is the percent yield
Explanation:
Based on the reaction:
CaCl₂ + Na₂CO₃ → 2NaCl + CaCO₃
<em>Where 1 mole of CaCl₂ in excess of sodium carbonate produces 1 mole of calcium carbonate.</em>
<em />
To solve this question we must find the moles of CaCl2 added = Moles CaCO₃ produced (Theoretical yield). The percent yield is:
Actual yield (0.366g) / Theoretical yield * 100
<em>Moles CaCl₂ = Moles CaCO₃:</em>
0.0500L * (0.0900moles / L) = 0.00450 moles of CaCO₃
<em>Theoretical mass -Molar mass CaCO₃ = 100.09g/mol-:</em>
0.00450 moles of CaCO₃ * (100.09g / mol) = 0.450g of CaCO₃
Percent yield = 0.366g / 0.450g * 100
81.26% is the percent yield
