Answer:

Its changes over time.

Explanation:

I think because each ocean current has a different temperature.

Answer:

Thermohaline circulation. This is a process driven by density differences in water due to temperature (thermo) and salinity variations in different parts of the ocean. Currents driven by thermohaline circulation occur at both deep and shallow ocean levels and move much slower than tidal or surface currents.

Answer:

There are four categories of byproduct material: Radioactive material that results from the fissioning, or splitting apart, of enriched uranium or plutonium in nuclear reactors. Examples include cobalt-60, cesium-137 and iridium-192. Tailings or waste produced by processing uranium or thorium from ore.

Answer:

Yes Calcium is more reactive than Lead.

Explanation:

Answer:

Yeah.

Calcium is in group II and lead is in group IV.

Since reactivity decreases from left to right of the periodic table, calcium reacts severely than lead

Effective watershed management requires the cooperation of everyone located near the watershed because if one person doesn't cooperate, it would fail.

Effective watershed management requires the cooperation of everyone located near the watershed since if one person doesn't cooperate, it should be fail.

It refers to the management that decreased the energy which is required for water treation, the water should be moved, and there should be the wastage of the water around. Also, it decreased the size and the infrastructure system should be decreased

Therefore, Effective watershed management requires the cooperation of everyone located near the watershed since if one person doesn't cooperate, it should be fail.

Answer:

25N

Explanation:

The force calculated to be 25kgm/s² has a value of 25N.

To solve this problem, we need to consider the unit of force. The unit of force is expressed in N, newtons.

  To find force;

           Force  = mass x acceleration

            Unit of mass  = kg

                      acceleration  = m/s²

 So;

        1N  = 1kgm/s²

Therefore 25kgm/s² is the same as 25N

Answer:

Milk

Explanation:

Main compounds of milk are lactose and casein. And it is also called a colloidal mixture (i.e. in which one substance of microscopically dispersed insoluble or soluble particles is suspended throughout another substance). Therefore milk is regarded as a mixture not as a pure substance. So this is the required answer.

Answer:

b- 232%

Explanation:

Renewable energy consumption by energy source in 2006 = 6.659 quadrillion Btu

Renewable energy consumption by energy source in 2010 = 8.049 quadrillion Btu.

In 2006, wind energy = 4%

∴ wind energy = 4% x 6.659 = 0.26636

In 2010, wind energy = 11%

∴ wind energy = 11% x 8.049 = 0.88539

∴ Percent increase = (final number - initial number) ÷ (initial number) x 100

% increase = [(0.88539 - 0.26636) ÷ 0.26636} x 100 = 232.4035% ≈ 232%.

Answer = 232%.

Answer:

The solubility curve helps us to predict which substance will crystallize out first from a solution containing two or more solutes.

The solubility curve helps us to compare the solubilities of different substances at the same temperature.

Solubility curve can be used to determine the amount of substance deposited when the solution is cooled.

It brings the change in the solute composition substance.

Answer:

1, we can know the solubility curve of substances.

2, we can compare the solubility curve of two or more substances in same temperature.

3, we can know the amount of solute and solvent which is used that solubility.

4, we can know that solubility of substances changes with temperature.

Answer: The number of formula units present in 2 moles of [tex]C_6H_{12}O_6[/tex] are [tex]1.2044\times 10^{24}[/tex]

Explanation:

Formula units are defined as the number of molecules or atoms present in 1 mole of a compound or element respectively.

According to mole concept:

1 mole of a compound contains [tex]6.022\times 10^{23}[/tex] number of formula units

Here, 2 represents the number of moles of [tex]C_6H_{12}O_6[/tex]

We are given:

Moles of [tex]C_6H_{12}O_6[/tex] (glucose) = 2 moles

Number of formula units of [tex]C_6H_{12}O_6=(2\times 6.022\times 10^{23})=1.2044\times 10^{24}[/tex]

Hence, the number of formula units present in 2 moles of [tex]C_6H_{12}O_6[/tex] are [tex]1.2044\times 10^{24}[/tex]

Answer:

1. Mass of CaCl2 salt in grams

2. Volume of water in calorimeter

3. Mass of water in calorimeter

4. Mass of salt and water solution

5. Initial temperature of water

6. Final temperature of water

7. Temperature difference or change

Explanation:

The amount of heat absorbed or released during a chemical reaction is measured by the process of calorimetry. A calorimeter is a device used for the heat measurements in calorimetry. It consists of an insulated vessel that prevents heat exchange with the environment. The quantity of heat absorbed or released by a chemical reaction is calculated using the following formula: Q = mc∆t

The molar heat of solution, ∆Hsoln, of a substance is the heat absorbed or released when one mole of the substance is dissolved in water. In determining the molar heat of solution of a salt, e.g. calcium chloride, the following measurements are required:

1. Mass of CaCl2 salt in grams

2. Volume of water in calorimeter

3. Mass of water in calorimeter

4. Mass of salt and water solution

5. Initial temperature of water

6. Final temperature of water

7. Temperature difference or change

Answer:

Second order

Explanation:

We could obtain the order of reaction by looking at the table very closely.

Now notice that in experiment 1 and 2, the concentration of [OH^-] was held constant while the concentration of [S8] was varied.  So we have;

a situation in which the rate of reaction was tripled;

0.3/0.1 = 2.10/0.699

3^1 = 3^1

Therefore the order of reaction with respect to  [S8] is 1.

For [OH^-], we have to look at experiment 2 and 3 where the concentration of [S8] was held constant;

x/0.01 = 4.19/2.10

x/0.01 = 2

x = 2 * 0.01

x = 0.02

So we have;

0.02/0.01 = 2^1

2^1 = 2^1

The order of reaction with respect to  [OH^-] = 1

So we have the overall rate law as;

Rate = k[S8]^1  [OH^-] ^1

Overall order of reaction = 1 + 1 = 2

Therefore the reaction is second order.

Answer: Hydrologic Cycle!

The new temperature (T₂) in the lab = 25.09 °C

Given

V₁=2.15 ml

T₁ = 17 + 273 = 290 K

P = 740.2 mmHg

V₂ = 2.21 ml

Required

The new temperature (T₂)

Solution

Charles's Law

When the gas pressure is kept constant, the gas volume is proportional to the temperature

[tex]\tt \dfrac{V_1}{T_1}=\dfrac{V_2}{T_2}[/tex]

Input the value :

T₂=(T₁.V₂)/V₁

T₂=(290 K x 2.21 ml)/2.15 ml

T₂=298.09 K = 25.09 °C

Answer:

Pressure is inversely proportional to the volume of a gas at constant temperature and number of moles

Temperature is directly proportional to volume at constant pressure and number of moles

Volume is directly proportional to the number of moles of a gas at constant temperature and pressure

Explanation:

The ideal gas law is derived from a combination of the Boyle's, Charles' and Avogadro's law of gases.

Boyle's law states that at constant temperature, the volume of a given mass of gas (number of moles of gas is constant) is inversely proportional to the pressure exerted by the gas.

V ∝ 1/P (at constant n, T)

Charles'law states that at constant pressure, the volume of a given mass of gas (constant amount, n) is directly proportional to the temperature of the gas; V ∝ T (at constant n, P)

Avogadro’s law states that at constant temperature and pressure, the volume of a given mass of gas is directly proportional to the number of moles of gas present; V ∝ n(at constant T, P)

Combining the three equations gives the following relationship: V ∝ nT/P

By inserting a proportionality constant called the molar gas constant, R, in the relationship above, the ideal gas equation is derived as follows:

V = nRT/P or PV = nRT

Answer:

T₂  = 956.0 K

Explanation:

Given data:

Initial temperature = 273.15 K

Initial pressure = 1 atm

Final pressure = 3.5 atm

Final temperature = ?

Solution:

According to Gay-Lussac Law,

The pressure of given amount of a gas is directly proportional to its temperature at constant volume and number of moles.

Mathematical relationship:

P₁/T₁ = P₂/T₂

Now we will put the values in formula:

1 atm / 273.15 K = 3.5 atm / T₂

T₂  = 3.5 atm ×273.15 K / 1 atm

T₂  = 956.0 atm. K /  1 atm

T₂  = 956.0 K
