Explanation:

It <em><u>provides an objective, standardized approach to conducting experiments</u></em> and, in doing so, improves their results. By using a standardized approach in their investigations, scientists can feel confident that they will stick to the facts and limit the influence of personal, preconceived notions.

I hope this helps you out!

What is the specific heat of iron, if it requires 1120 J of heat energy to raise the
IRISSAK [1]

Answer:

Specific heat is defined as the amount of heat needed to raise the temperature by one degree celsius. Therefore, in 1 kg there are 100 grams so, 10 grams equal 0.01 Kg. Thus, calculate the specific heat value as follows. Thus, we can conclude that specific heat of the given metal is 0.5 .

Some students performed a titration between 20.0 mL of 0.5 M hydrochloric acid and 1.0 M potassium hydroxide solution. The stude
RideAnS [48]

Answer:

OPTION C) All hydrogen ions and all hydroxide ions have reacted to produce water, and so neither ion remains free in solution.

Explanation:

The PH reading on the left axis of the graph shows a value of 7.

A value of 7 on the PH scale implies that equal number of hydrogen ions completely reacted with hydroxyl ions to produce water i.e there is no excess of hydrogen and hydroxyl ion remaining in solution.

For values greater than 7, a basic solution is formed and it signifies the presence of excess hydroxyl ion. If the value is less than 7, there is more hydrogen ions in the solution formed and it is said to be acidic.

At point 7, the hydrogen and hydroxyl ions are equal and completely neutralize out one another.

Note: The acid solution would require a base volume of 20mL to be completely neutralized according to the plot. If it is less, the PH shifts to the left and the solution becomes acidic. If it more, the solution becomes basic and the PH shifts rightwards.

How many grams of Al would be needed to displace all of the copper ions in 71.8 mL of 0.610 M CuSO4?
Galina-37 [17]

The amount of Al that would be needed will be 0.79 grams

<h3>Stoichiometric calculations</h3>

From the equation of the reaction below:

2 Al + 3 CuSO_4 --- > Al_2(SO_4)_3 + 3 Cu

The mole ratio of Al to CuSO_4 is 2:3.

Mole of 71.8 mL. 0.610 M  CuSO_4 = 0.610 x 71.8/1000 = 0.0438 moles

Equivalent mole of Al = 2/3 x 0.0438 = 0.029 moles

Mass of o.o29 moles Al = 0.029 x 26.98 = 0.79 grams
