A gram of gasoline produces 45.0kj of energy when burned. gasoline has a density of 0.77/gml . how would you calculate the amoun
babymother [125]
Given that there is 48 liters of gasoline to be burned and that 45 kJ of energy is released per gram of gasoline burned, the amount of energy that the gasoline fuel produces can then be calculated, First, we convert 48 liters of gasoline to units of mass (grams) in order to use the given conversion of 45 kJ per gram of gasoline. To do this, we use the density of gasoline which is 0.77 g/mL. The following expression is then used:

48 L gasoline x 1000 mL/L x 0.77 g/mL x 45 kJ/g gasoline = 1663200 kJ

<span>The amount of energy produced by burning 48 L of gasoline was then determined to be 1663200 kJ. </span>

Complete the equation for the dissociation of Fe(ClO4)3(aq). Omit water from the equations because it is understood to be presen
victus00 [196]

Answer:

The equation that tends to answer this question, (omitting the presence of water) is:

Fe (ClO4) 3 -----------> Fe (+3) + ClO4 (-1)

Explanation:

The numbers that we see in parentheses would be the oxidation numbers of each compound, in the case of iron, iron acts with an oxidation number of +3, and in the case of perchlorate it would be -1.

The stoichiometric name according to IUPAC (most widely used chemical nomenclature) is iron perchlorate.

Explain the trend in reactivity of the halogens 6 marks
mojhsa [17]

Answer:

The reactivity of Group 7 elements decreases down the group. ... The electrons in the outer shell move further away from the nucleus as we go down the group and the attraction force between the electrons and the nucleus become weaker and weaker. This weaker attraction in the larger atoms makes it harder to gain electron.
