A____H means that energy is ____ from a reaction.

ExtremeBDS [4]

Answer:

A negative ∆H means that energy is given off from a reaction

Explanation:

$2NO_2 (g)N_2 O_4 (g)\\\\\Delta H=-58 KJ per mol$

If the reaction has negative ∆H value then the reaction is exothermic

$N_2 O_4 (g)2NO_2 (g)\\\\\Delta H=+58 KJ per mol$

If the reaction has positive ∆H value then the reaction is endothermic

When Heat energy is given in the equation itself

If it is present on the left side it means that heat is absorbed and the reaction is Endothermic

If it is present on the right side it means heat is given off and the reaction is exothermic

a particular mp3 encoder can convert 93.0 kilobytes of music per second from a typical music CD.How many minutes will it take to

klemol [59]

To answer this question, you need to convert the 16.1 megabyte into second first. If the rate is 93kb/second, then the calculation would be:
16.1 mb x (1000kb/mb) / (93kb/second)= 173.12 second.
Then 16.1 mb music will last for 173.12 second. After that you can convert it into minutes: 173.12/ (60second/min)= 2.885 minutes.

Two samples of carbon tetrachloride were decomposed into their constituent elements. One sample produced 32.4 g of carbon and 37

Gnoma [55]

Answer:

The answer to your question is:

Explanation:

Law of constant composition states that a given compound always contains its component elements in a fixed ratio.

Data

Sample 1 32.4 g of C and 373 g of Cl

Sample 2 12.3 g of C and 112 g of Cl

Convert the grams to moles and compare the ratios

Sample 1 Sample 2

12 g of C --------------- 1 mol 12 g of C -------------- 1 mol

32.4 g ---------------- x 12.3 ------------- x

x = (32.4 x 1) / 12 x = (12.3 x 1) / 12

x = 2.7 moles of C x = 1.025 moles of C

35.5 g of Cl ---------- 1 mol 35.5 g of Cl ---------- 1 mol

373 g ------------------ x 112 g of Cl ----------- x

x = (373 x 1) / 35.5 x = (112 x 1) / 35.5

x = 10.5 moles of Cl x = 3.15 moles of Cl

Ratio

10.5 / 2.7 = 3.9 3.15/1.025 = 3.1

The ratio must be equal in both samples to say that the law is constant. So the answer is NO.

What is the number of molecules in CaCo3

Damm [24]

Answer:

Solution — Molar mass (Molecular mass in gram) of CaCO3 = 40+12+3×16 = 100 g No. of moles of CaCO3 = No. of molecules/Avogadro constant = 6.022 × 1023/ 6.022 × 1023 = 1 mole Mass of CaCO3 = No. of moles × molar mass = 1 × 100 g = 100 g.
