<span>The three main types of erosion caused by glaciers are plucking, abrasion, and freeze thawing. Plucking forces rocks off of the back wall when glacier water melts and re-freezes around cracked and broken rocks. Abrasion occurs when rocks frozen to the base of the glacier scrape the bed rock. Freeze thawing occurs when melted water gets into the bed rock. An outwash plain is an area formed by sediments at the terminus of a glacier. Outwash plains may contain suficial braided stream complexes, and kettle lakes. The outwash plains originate from melting ice deposits.</span>

Which pair of elements would most likely combine to form a salt? I and F Cs and I Na and C N and F
Savatey [412]

Answer:

Cs and I

Explanation:

Salts are formed when an ionic bond is formed between two elements in the compound. Let us recall that the kind of bond formed between any two elements depends on the magnitude of electronegativity difference between the two elements.

Among the options listed, the highest degree of electronegativity difference occurs for the bond between Cs and I. This implies that this bond is ionic and the combination of the two elements will lead to salt formation.

Predict the bond angles for each of the following labeled bonds.
boyakko [2]

The bond angles a and b are 120° respectively. The bond angle c is 111.4° .while the bond angle d is 120°. The bond angles e and f are 120° respectively.

In the carbonate ion, all the bond angles and bond lengths are equal hence three equivalent resonance structures can be drawn for the ion. All the bond angles, ( a and b) in carbonate ion all have bond angle of 120°.

The bond angle marked c in OCCl2 has a bond angle 111.4°, the bond angle marked d in the compound has the bond angle, 120°.

There are three bond angles present in the nitrate (NO3-) ion. Three resonance structures contribute to this bond. Based on these structures, the bond angles e and f in the molecule is 120°.

If a 250.0 mL sealed plastic bag starts out at a temperature of 19.0 °C and after sitting in the sun reaches a temperature of 60
Marizza181 [45]

Answer:

D

Explanation:

If the pressure remains constant then the temperature and Volume are all that you have to consider.

Givens

T1 = 19oC = 19 + 273 = 292o K

T2 = 60oC = 60 + 273 = 333oK

V1 = 250 mL

V2 = x

Formula

V1/T1 = V2/T2

250/292 = x/333                

Solution.

The solves rather neatly.  Multiplly both sides by 333

250*333 / 292 = 333 *x / 333

Do the multiplication

250 * 333 / 292 = x

83250 / 292 = x

Divide by 292

x = 285.1 mL

The answer is D

Calculate the density for a rectangular block using the following measurements: Length = 10 cm, Width = 1.1 cm, Height = 15 cm,
Ksivusya [100]

Answer:

0.40 g/cm3

Explanation:

density = mass / volume.

mass = 65.2 grams

volume = 10*1.1*15=165 cm3

so density = 65.2/165=0.40 g/cm3
