Answer: D. Wind Forces

Explanation: Think about it. We're talking about movement of the surface of a body of water. Temperature, Salinity, and density doesn't cause water to move, or rather, the surface of water to move. Wind is the only logical answer.

Calculate the moles and grams of solute in 2.0 L of 0.30M Na SO..
Ostrovityanka [42]

Answer:

Number of moles of solute = 0.6 mole

Mass =13.8 g

Explanation:

Given data:

Number of moles of sodium = ?

Volume = 2.0 L

Molarity = 0.30 M

Mass in gram of sodium= ?

Solution:

<em>Number of moles:</em>

Molarity = number of moles of solute / volume in litter

Number of moles of solute = Molarity × volume in litter

Number of moles of solute = 0.30 M × 2.0 L

Number of moles of solute = 0.6 mole

<em>Mass in gram:</em>

Mass = Number of moles × molar mass

Mass = 0.6 mole× 23 g/mol

Mass =13.8 g

How many grams of H2 will react with 350 g of N2?
miss Akunina [59]

Answer:

10.80

Explanation:

As per the equation, let us calculate the mole ratio. N2+3H2→2NH3. As per the equation one mole of nitrogen  reacts with 1 mol of hydrogen.

In terms of mass. 28.01 g of nitrogen needs 3 mol of hydrogen or 6.048 g of hydrogen.

We can set up the ratio;

1. carbon cycle
marin [14]

Explanation:

1. carbon cycle

all of the physical processes and chemical reactions that result in the movement of carbon between the biosphere (living forms) and the geosphere (water, earth, and atmosphere)

  Carbon cycle is the cyclic movement of carbon in various form on earth. This process entails both physical and chemical processes that ensures that carbon moves in different spheres of the earth. Carbon is one of the most important element in life. It is the building block of most organic processes on earth.

2. carbon footprint

a calculation that considers an individual's contribution to the process of global warming based on activities leading to greenhouse gas production

Carbon footprint is important in mapping the quota of carbon emitted into the atmosphere

It is the amount of greenhouse gases contributed into the atmosphere by individuals.

3. global warming

an overall increase in world temperatures that may be caused by additional heat being trapped by greenhouse gases

   It is the overall increase in global temperature. It has severe consequences.

  Global warming results when greenhouse gases in the atmosphere traps outgoing radiation in an anomalous way.

4. greenhouse gas

components of the air mixture that trap infrared (heat) energy

 Greenhouse gases are gases that prevents long wave radiation from leaving the earth surface. They absorb the gases in turn, warming occurs on earth.

When an ionic compound dissolves in water:_________.
Katarina [22]

Answer:

a. the negative ends of water molecules surround the positive ions.

Explanation:

Ionization reaction is defined as the reaction in which an ionic compound dissociates into its ions when dissolved in aqueous solution.

Thus,

NaCl_{(s)}\rightarrow Na^+_{(aq)}+Cl^-_{(aq)}

When the ionic compound dissociates, the cation which is positively charged gets attracted to the oxygen (Negative ends) which is present in the water. The anion which is negatively charged gets attracted to the hydrogen (Positive ends) of the water.

Hence, the correct option is:- a. the negative ends of water molecules surround the positive ions.
