consider a 1000-ml graduated cylinder with marks every 100 ml. a student records the volume of liquid in the cylinder as 750 ml.

kap26 [50]

Answer:

Yes, given statement is true.

Explanation:

Given that a cylinder of 1000 ml is marked at every 100 ml.

During the test, the student can easily check the volume of liquid so the student's guess is 750 ml true.

With this measurement, we can estimate that 1/10th of 100 ml can be measured.

So, given statement is correct.

C₂H₅0H+30₂→2CO₂+3H₂0,the change of enthalpy was ΔH= - 1235.7 KJ/mol

igor_vitrenko [27]

Answer:

The total enthalpy of the reaction has negative value which mean that the heat is lost during the chemical reaction into surroundings.

Explanation:

Exothermic reactions are defined as the reactions in which energy of reactants is more than the energy of the products. In these reactions, energy is released by the system.

The total enthalpy of the reaction $(\Delta H)$ comes out to be negative.

Endothermic reactions are defined as the reactions in which energy of products is more than the energy of the reactants. In these reactions, energy is absorbed by the system.

The total enthalpy of the reaction $(\Delta H)$ comes out to be positive.

$C_2H_5OH+3O_2\rightarrow 2CO_2+3H_2O$ ,ΔH= -1235.7 kJ/mol

The total enthalpy of the reaction has negative value which mean that the heat is lost during the chemical reaction into surroundings.

A sample of an iron ore is dissolved in acid, and the iron is converted to Fe2+. The sample is then titrated with 47.20 mL of 0.

Shalnov [3]

Answer:

33.21% is the right answer.

Explanation:

0.04720 L * 0.02240 mol / L = 1.0573*10-3

mol Fe+2 = 1.0573* 10-3 mol = 5.2864*10-3

mass of Fe= 5.2864 * 10-3 = 0.29522g

% of Fe in sample = 0.29522 g Fe / 0.8890 g of sample * 100 = 33.21%
