How are regional climate patterns caused by atmospheric and ocean flows

Answers

Answer:

Ocean currents act as conveyer belts of warm and cold water, sending heat toward the polar regions and helping tropical areas cool off, thus influencing both weather and climate. .

Liquids and solids are left out of the equilibrium constant expression because their concentrations remain constant during reactions. What is the molarity concentration of liquid water at 25.0 LaTeX: ^\circ ∘C given that its density is 0.997 g/mL at that temperature? a.23.5 M
b.0.997 M
c.0.180 M
d.0.156 M
e.55.3 M

Answers

Answer:

55.3 M

Explanation:

Given temperature = 25°C

Density = 0.997 g/mL

Based on density the mass of water per L = 997 grams

The molar mass of water = 18

The moles of water = (mass)/(molarmass)=(997)/(18)=55.3

The molarity is defined as the moles of water per litre.

The moles = 55.3

Volume = 1 L

So molarity = 55.3 /1 = 55.3 M

Which of the following statements is not true regarding acids?Most fruits contain weak acids.

Acids react with bases in neutralization reactions to produce water.

Acids can be both highly and mildly corrosive.

Active metals will react with acids in double replacement reactions.

Answers

The correct answer is the last option. Active metals will not react with acids in double replacement reactions. Instead, it reacts with metals via sing replacement reactions. It will displace hydrogen from the acid.

2. Based on what you know about waves and light, do you think that light can bemodeled as a wave? Explain why or why not.

Answers

Answer:

Light as a wave: Light can be described (modeled) as an electromagnetic wave. In this model, a changing electric field creates a changing magnetic field. This changing magnetic field then creates a changing electric field and BOOM - you have light. ... So, Maxwell's equations do say that light is a wave.
