Explanation:
Claim, Evidence, Reasoning (CER) model, an explanation consists of: A claim that answers the question. Evidence from students' data. Reasoning that involves a rule or scientific principle that describes why the evidence supports the claim.
Molarity is moles per liter. Therefore you must covert grams->moles by dividing 9.82 by the molar mass of lead IV nitrate. Then convert mL->L. Once you have those two numbers you can plug them into the formula Molarity = mol/L.
The answer is accuracy.
That is when a test instrument is calibrated, its accuracy is improved. That is the result comes more close to what it is.
The other factor will not be improved that is its reliability and precision remains the same.
So the answer is accuracy is improved when a test instrument is calibrated.
The sum of all coefficients = 7
<h3>Further explanation</h3>
Given
The word equation
Required
The sum of all coefficients
Solution
The chemical equation can be expressed in terms of:
- word equation
- skeleton equation
- balanced equation
Convert the word equation into a chemical equation(skeleton) :
Ga + Cl₂ → GaCl₃
Balanced equation
2Ga + 3Cl₂ → 2GaCl₃
The sum of all coefficients :
= 2+3+2
= 7
