What is the main cause of global convection currents?​

Answers

Answer:

The main cause of global convection currents is the uneven heating of the earth by the sun. Hope this helped! :)

The main cause of global convection current is differential heating, that is the temperature difference in different levels of  atmosphere.

What is convection current?

Convection current  is the heat transfer by fluid movement in the earth crust between different temperature regions. The density of fluids differs due to the temperature gradients and thus heated fluids raises and cooled fluid sinks.

The heated fluid movement causes the movement of plates of earth. The molten rock deep inside the earth crust circulates by the convection current.

Hence, the main cause of global convection current is the differential heating of the atmosphere.

Mass = 35g Volume = 7cm³ What is the Density?​

Answers

Answer:

The answer is

5.0 g/cm³

Explanation:

The density of a substance can be found by using the formula

[tex]density = \frac{mass}{volume} \\ [/tex]

From the question

mass = 35 g

volume = 7 cm³

The density is

[tex]density = \frac{35}{7} \\ [/tex]

We have the final answer as

A six row combin harvests 266 pounds of corn per min. How many bushels of corn does it harvest per hour? (Note: 1 Bu = 56 Lbs) Round to the nearest Whole Number.

Answers

Answer:

The six-row combin harvests 285 bushels of corn per hour.

Explanation:

The rule of three or is a way of solving problems of proportionality between three known values and an unknown value, establishing a relationship of proportionality between all of them. That is, what is intended with it is to find the fourth term of a proportion knowing the other three.

If the relationship between the magnitudes is direct, you can apply the following formula:

a ⇒ b

c ⇒ x

So: [tex]x=\frac{a*b}{c}[/tex]

In this case you can apply it in the following way: if 56 pounds is equal to 1 bushel, 266 pounds to how many bushels is it?

[tex]x=\frac{266 pounds*1 bushel}{56 pounds}[/tex]

x=4.75

This is, a six row combin harvests 4.75 bushels of corn per min.

So, being 1 hour equal to 60 minutes, you can apply the following rule of three: if in 1 minute a six-row harvester harvests , in 60 minutes how many bushels of corn it harvests?

[tex]bushels of corn=\frac{60 minutes*4.75 bushels of corn}{1minute}[/tex]

bushels of corn=  285

The six-row combin harvests 285 bushels of corn per hour.

This element has three fewer protons than oganesson 

Answers

Answer:

ununpentium

Explanation: this is element 115, Oganesson has 118

The atomic number of oganesson is 118. The element which  is having three fewer protons than oganesson is moscovium (Mc) (115).

What is oganesson?

Oganesson is a newly found element synthesized in 2002 and is placed as 118'th element in the periodic table.  In modern periodic table, the elements are arranged based on their atomic number.

Atomic number is the number of protons in the atom as well it is the number of electrons in the neutral atom. For a neutral atom the number of electrons are protons are equal.

Thus in a neutral atom the positive charges are neutralized by equal number of negative charges.

Thus, for 118'th element, there are 118 protons, three fewer from this means, there are 115 protons, the 115'th element in the modern periodic table is moscovium.

The hail can be defined as the conversion of the water to the ice. Thus, hail is an example of freezing.

What is phase change?

The phase can be defined as the state of the matter. With the change in the temperature and the pressure values, the state of the matter, or the phase changes.

The hail has been the solid precipitation of the rain water. With the lowering of the temperature to the critical pressure, the water converts to ice.

The conversion of water to ice has been termed as freezing, Thus, hail is an example of freezing. Hence, option D is correct.

If 5.0 g of copper cools from 35.0oC to 22.6 oC and loses 23.6 J of heat, what is the specific heat of copper? a. 0.038 J/(g. oC) b. 0.62 J/(g. oC) c. 0.076 J/(g. oC) d. 0.38 J/(g. oC)

Answers

Answer:

c = 0.38 J/(g-°C)

Explanation:

Given that,

Mass of copper, m = 5 g

Initial temperature, [tex]T_i=35^{\circ} C[/tex]

Final temperature, [tex]T_f=22.6^{\circ} C[/tex]

When copper cools, it looses 23.6 J of heat. We need to find the specific heat of copper. The heat lost is given by :

[tex]Q=mc\Delta T[/tex]

c is specific heat

[tex]c=\dfrac{Q}{m\Delta T}\\\\c=\dfrac{23.6}{5\times (22.6-35)}\\\\c=0.38\ J/g-^{\circ} C[/tex]

Hence, the correct option is d.

4. What is the proper way to prepare an acid solution?

Answers

Answer:

Always add acid to a large volume of water. The solution may then be diluted with additional water to make one liter. You'll get an incorrect concentration if you add 1 liter of water to the acid.

An acid is concentrated solution hence, it should be added to considerable quantity of water. The required volume can then be adjusted by adding more water.

What are the properties of an acid?

Acids form aqueous solution and have the property of electric conductivity. Acids reacts with other molecules by forming a covalent bond.

Acids are corrosive in nature, sticky to touch, tastes sour and have strong smell.

Acids can be qualitatively detected through litmus test. They turn blue litmus paper red. Their pH is < 7 on pH scale.

Acids can be classified as:

Strong acids - are the acids that dissociate in water completely.Weak acids - are the acids that partially dissociate in water.

Chemically, acids can react with other metals, carbonates and bases. Common examples of acids are vinegar (acetic acid), hydrochloric acid (HCl), sulfuric acid (H2SO4) etc.

Acids are found in food items such as citrus fruits. Acetic acid is widely used in certain food preparations and as food preservative. Acids are commercially used in dyes, paints and in soft drinks.

Thus, acids are important in many chemical reactions.
