How does heat cause ocean currents

Answers

Answer 1
Convection occurs because the oceanic waters heat up becoming less dense. .This water moves above the cooler water, and give off its heat to the surrounding environment. As it cools, it begins to sink, and the process begins again.

How many molecules are equal to 10.35 g of pyridine?

Answers

Answer:

0.78× 10 ²³ molecules

Explanation:

Given data:

Mass of pyridine = 10.35 g

Number of molecules = ?

Solution:

Number of moles of pyridine:

Number of moles = mass/molar mass

Number of moles = 10.35 g/ 79.1 g/mol

Number of moles = 0.13 mol

Number of molecules;

1 mole contain 6.022× 10 ²³ molecules

0.13 mol × 6.022× 10 ²³ molecules / 1mol

The pressure in a bicycle tire is 105 psi at 25˚C in Fresno. You take the bicycle up to Huntington, where the temperature is – 5˚C. What is the pressure in the tire?

Answers

Answer:

94.4 Psi

Explanation:

Given that;

P1 = 105 psi

T1 = 25˚C + 273 =  298 K

P2 = ?

T2 = – 5˚C + 273 = 268 K

P1/T1 = P2/T2

P1 T2 = P2T1

P2 = P1T2/T1

P2 = 105 * 268/298

P2= 94.4 Psi

If a sample of gas of valume 605 mL and temperature of 39 OC, has 0,00803 moles. What is it’s pressure?

Answers

Answer:

The pressure of the gas is 0.35 atm.

Explanation:

We can find the pressure of the gas by using the Ideal Gas Law:

[tex] P = \frac{nRT}{V} [/tex]

Where:

V: is the volume = 605 mL = 0.605 L

n: is the number of moles = 0.00803 moles

T: is the temperature = 39 °C = 312 K

R: is the gas constant = 0.082 L*atm/(K*mol)

Hence, the pressure is:

[tex] P = \frac{0.0083 moles*0.082 L*atm/(K*mol)*312 K}{0.605 L} = 0.35 atm [/tex]

Therefore, the pressure of the gas is 0.35 atm.

Zinc is gotten after Zinc oxide is heated in the presence of carbon.

This process is smelting.

Concentrated tetraoxosulphate acid is a strong dehydrating agent. It has the ability to char wood, paper, or sugar, leaving a carbonaceous residue. The charring effect is as a result of the carbon that is found in the wood.

The acid sucks in the oxygen and hydrogen, leaving behind the carbon; this results in the charring effect.

If the [OH-] of a solution is 2.7 x 10-4 mol/L the pOH of the solution is

Answers

Answer:

14/2.1 thats just what i do

Explanation:

If the [OH⁻] of a solution is  2.7 × 10⁻⁴ mol/L the pOH of the solution is 3.569.

What is pH ?

pH is used to measure whether the substance is acidic, basic or neutral and the range is 0-14.

How to find the pOH of the solution ?

To calculate the pOH it is expressed as:

pOH = - log[OH⁻]

        = - log[2.7 × 10⁻⁴]

        = - [log 2.7 + log  10⁻⁴]                        [log a × b = log + log b]

        = - [log 2.7 - 4 log 10]                          [log aˣ = x log a]

        = - [log 2.7 - 4 × 1]                                [log 10 = 1]

        = - [log 2.7 - 4]

        = - [0.431 - 4]

        = - [-3.569]

        = 3.569

Thus, from above conclusion we can say that If the [OH⁻] of a solution is  2.7 × 10⁻⁴ mol/L the pOH of the solution is 3.569.

48g of magnesium and 32g of oxygen react to form 80g of magnesium oxide. 2Mg + O2 --> 2MgO What mass of oxygen is needed to make 20g of MgO?

Answers

Answer:

8g

Explanation:

1mole of oxygen -->2moles MgO

32g --> 80g

?g --> 20g

(20x32)÷80

= 8g oxygen

Answer:

Mass of oxygen needed  = 8 g

Explanation:

Given data:

Mass of oxygen needed = ?

Mass of MgO formed  = 20 g

Solution:

Chemical equation:

2Mg + O₂     →    2MgO

Number of moles of MgO:

Number of moles = mass/molar mass

Number of moles = 20 g/ 40 g/mol

Number of moles = 0.5 mol

Now we will compare the moles of MgO and O₂:

                        MgO         :            O₂

                           2            :            1

                          0.5          :        1/2×0.5 = 0.25 mol

Mass of oxygen needed:

Mass = number of moles × molar mass

Mass = 0.25 mol × 32 g/mol

Mass = 8 g

Answers

Answer:

A derived unit is defined as the unit that is created from a  product of SI base units. Volume is an example of derived unit because it is not possible to measure volume directly using any measuring device For eg., Volume of water in bucket is can not be measured using rule, or scale, or any other measuring device.

Hence, volume is a derived unit.

how it causes change:  Volcanoes can be extremely dangerous to earth because it can impact climate change. During major explosive eruptions huge amounts of volcanic gas, aerosol droplets, and ash are injected into the stratosphere.

what is the effect of the change: Major eruptions alter the Earth's radiative balance because volcanic aerosol clouds absorb terrestrial radiation, and scatter a significant amount of the incoming solar radiation, an effect known as "radiative forcing" that can last from two to three years following a volcanic eruption.

for an electron to move from an energy level that was close to the nucleus to an energy level that is far from the nucleus would it need to gain or lose energy ?

Answers

Answer:

it would need to lose energy

Explanation:

I don't really have an explanation

As the electrons gets closer to the nucleus, by the electrostatic force of attraction electrons are tightly bound to the nucleus. To move the inner electron to outer shell, high energy have to applied to weaken the nuclear force.

What is nuclear force?

Nuclear force is the force by which the nucleon are bind in the nucleus and electrons are attracted towards the nucleus. The positively charged protons inside the nucleus electrostatically attracts the negatively charged electrons.

The minimum amount of energy required to remove an electron from the valence shell by overcoming the nuclear force is called ionization energy.

To bring an electron which is closer to the nucleus to the outer shell needs much energy to reduce the nuclear attractive pull. The energy need to gain.

Answers

Answer:

Explanation:

Sabemos que podemos obtener la masa de una sustancia a partir del número de moles presentes de la siguiente manera;

número de moles = masa / masa molar

masa molar de 2-feniletanol (C5H5-CH2-CH2-OH) = 122,16 g / mol

masa = 0.03 moles * 122.16 g / mol = 3.66 g de 2-feniletanol (C5H5-CH2-CH2-OH)
