An atom that accepts an electron to achieve a more stable configuration is assigned an oxidation number of -1. The donation of an electron is then +1. When a transition metal loses electrons, it tends to lose it's s orbital electrons before any of its d orbital electrons.

Given:1 inch = 2.54 cm (exact)1 pound = 454 g1 Liter = 1.0b quarts1 foot = 12 inches1 galion = 4 quarts1 pound = 16 ouncesCalcul
svet-max [94.6K]

We have to convert 0.18 km into feet

First, we need to know the conversions:

1 inch = 2.54 cm (exact)

1 pound = 454 g

1 Liter = 1.0b quarts

1 feet = 12 inches

1 galion = 4 quarts

1 pound = 16 ounces

0.18 km x (1 feet/12 inches) x (1 inch/2.54cm) x (1000 m/1 km) x (100 cm/1 m) = 590 ft

Answer: 590 ft (2 significant figures)

How much heat is released when 47.50 g of CH4 (g) is burned in excess oxygen gas to produce carbon dioxide and water?
Elina [12.6K]

Answer:

= 2113.44 kJ

Explanation:

When 1 mole of CH4 (g) burns in excess oxygen -714.0 kJ of heat is released.

For 47.50 g;

molar mass of CH4 = 16.042 g/mol

Number of moles of CH4

   = 47.5 g /16.042 g/mol

   = 2.96 moles

Therefore;

1 mole = -714.0 kJ

Heat change for 2.96 moles

 = 2.96 moles × -714.0 kJ

 = 2113.44 kJ

Chlorine has two isotopes. Chlorine-35 has an actual mass of 34.9689 u and chlorine-37 has a mass of 36.9659 u. In any sample of
pav-90 [236]

Answer: 1. The average atomic mass of chlorine is 35.453u

2. The average atomic mass of copper is 63.5 u

Explanation:

Average atomic mass is defined as the sum of masses of each isotope each multiplied by their natural fractional abundance.

Formula used to calculate average atomic mass follows:

\text{Average atomic mass }=\sum_{i=1}^n\text{(Atomic mass of an isotopes)}_i\times \text{(Fractional abundance})_i

1. For chlorine:

\text{Average atomic mass of chlorine }=(34.9689\times \frac{75.771}{100})+(36.9659\times \frac{24.229}{100})=35.453u

2.  For copper:

\text{Average atomic mass of chlorine }=(62.93\times \frac{69.1}{100})+(64.93\times \frac{30.9}{100})=63.5u
