What is the relishing hip between the chemical energy provided by the battery and the electrical energy produced according to the law of conservation of energy

Answers

Answer:

Equal

Explanation:

Energy is always conserved in the nature and it is an universal law. According to the law conservation of energy, it is said that energy can never be created out of something and we can never destroy and vanish any energy in any form. Energy in any form can only be transformed to some other forms of energy. This is known as conversion of energy.

In the context, the chemical energy that is produced by the battery and the electrical energy produced should be equal.

How do changes in wind currents affect the short-term climate in a region?

Prevailing winds can cause a milder climate with heavy rain.
Global winds can cause a longer summer.
Prevailing winds can cause heavy rains or a dry climate.
Global winds can cause a longer winter.

Answers

Answer:

a

Explanation:

Prevailing winds can cause a milder climate with heavy rain is the change that affects the short-term climate in a region, hence option A is correct.

What is wind currents?

Concentrated areas of winds are known as air currents. They primarily result from variations in the temperature or atmospheric pressure.

The horizontal and vertical currents are present at the mesoscale, whereas horizontal currents predominate at the synoptic scale.

A region's short-term climate can be dramatically impacted by changes in wind currents. As they move moisture from one place to another, prevailing winds can result in a milder climate with heavy rain.

As a result, the impacted area may see higher precipitation and a more temperate environment.

Therefore, prevailing winds can cause a milder climate with heavy rain can impact the short-term climate in a region.

What is element?

Element generally consist of atoms or we can atoms combine to form element. Atoms of an element is always same, means all the properties of all atoms of one type of element is same. Two or more than two atoms with different physical or chemical properties can not combine together to form an element.

For neutral atoms, ionization energy is positive, indicating that ionization is indeed an endothermic process. The higher the ionization energy of an atom, roughly speaking, the nearer the outer electrons are to nucleus. The element arranged in order of increasing ionization energy are Gallium, Phosphorus, Chlorine, Fluorine.

Therefore, the element arranged in order of increasing ionization energy are Gallium, Phosphorus, Chlorine, Fluorine.

Compounds are combinations of elements. The combination of those elements is specific to the compound. Some compounds have the exact same elements but in different amounts. Look at C6H12O6, which you hopefully recognize as glucose (think cellular respiration and photosynthesis. But ribose is a 5 carbon sugar and its formula is C5H10O5, which you hopefully recognize (think RNA). They both have the same elements, but have different numbers of each element (sugars all have the 1:2:1 ratio). When you're looking at a formula, it's wise to look for the capital letters. That indicates when a different element is present. For glucose, there's a capital C - carbon, a capital H - hydrogen, and a capital O - oxygen. Behind elements, the subscripts help indicate the number of each element that's present. In glucose, there are 6 carbons, 12 hydrogens, and 6 oxygens. How many carbons, hydrogens, and oxygens does ribose have in its formula?

Sucrose is an organic compound made by plants for quick energy. What type of organic compound is sucrose?


1-protein
2-carbohydrate
3-lipid
4-nucleic acid

Answers

Answer:

2-carbohydrate

Explanation:

Sucrose belongs to the carbohydrate family. It is a disaccharide which is derived from the condensation of glucose and fructose.

In the body, they are sources of energy for living processes. Upon hydrolysis such disaccharide produces tow monosaccharide units. Food substances that are energy rich will contain some of these organic molecules.

Sucrose is a specific type of organic compound classified as a carbohydrate and the correct option is option 2.

Carbohydrates are essential biomolecules made up of carbon, hydrogen, and oxygen atoms. Sucrose, also known as table sugar, is a disaccharide formed by the chemical bonding of one glucose molecule and one fructose molecule.

Plants produce sucrose through photosynthesis and use it as a readily available source of energy. When consumed by animals, including humans, sucrose is broken down into its constituent monosaccharides to provide fuel for various cellular processes.

Thus, the ideal selection is option 2.

1 Moles of Calcium.

1 Moles of Carbon.

3 Moles of Oxygen.

_____________________________________Question:

In the Question, It is asked that how many moles are present in the 1 mole of Calcium Carbonate, So as per information we have, there are 3 moles of oxygen present in Calcium Carbonate.

__________________________________________________________

Much simpler way to understand why there are 3 mole is look at the subscript along the element. There is no number in the subscript of Calcium and Carbon thus 1 Mole, There is 3 present in the subscript thus 3 moles of calcium. Remember that subscript suggests the number of moles of an element in only 1 MOLE OF COMPOUND

What is the mass of HF produced by three reaction of 3.0 10 to the 23 molecules of H2 with excess F2

Answers

Answer:

It is 20. g HF

Explanation:

H2 + F2 ==> 2HF  ...  balanced equation

Since the question is asking us to find the mass of product formed, we will want to first convert the molecules of H2 into moles of H2 (we could do this at the end of the calculations, but it's just as easy to do it now).

moles of H2 present (using Avogadro's number):  

3.0x1023 molecules H2 x 1 mole H2/6.02x1023 molecules = 0.498 moles H2

From the balanced equation, we see that 1 mole H2 produces 2 moles HF.  Therefore, we can now find the theoretical mass of HF produced from 0.498 moles H2:

0.498 moles H2 x 2 moles HF/1 mol H2 = 0.996 moles HF formed.

The molar mass of HF = 20.01 g/mole, thus...

0.996 moles HF x 20.01 g/mole = 19.93 g HF = 20. g HF formed (to 2 significant figures)

What is an element?

Element is defined as a substance which cannot be broken down further into any other substance. Each element is made up of its own type of atom. Due to this reason all elements are different from one another.

Elements can be classified as metals and non-metals. Metals are shiny and conduct electricity and are all solids at room temperature except mercury. Non-metals do not conduct electricity and are mostly gases at room temperature except carbon and sulfur.

The number of protons in the nucleus is the defining property of an element and is related to the atomic number.All atoms with same atomic number are atoms of same element.Each element has its own characteristic property.

In the periodic table hydrogen is placed in Group 1A (group 1) and helium is placed in Group 8A (group 18). The most likely reason for this is:

Answers

Answer:

This question appears incomplete

Explanation:

This question appears incomplete because of the absence of options. However, hydrogen is placed in group 1 because it has just one electron in it's outermost shell (which happens to be the only shell it has) just like every other group 1A/group 1 element. While helium is placed in group 8A/group 18 because it has a completely filled outermost shell (which is also the only shell it has) just like every other element in group 8A/group 18.

In the periodic table hydrogen is placed in Group 1A (group 1) and helium is placed in Group 8A (group 18). The most likely reason for this is configuration, energy level and properties.

Hydrogen is located in group 1 of the periodic table, although its electronic configuration is 1s¹ and its properties do not correspond to those of the alkali metals of that group. But in its electronic configuration you can see that it has only one electron in its outermost shell (which turns out to be the only shell it has), just like any other element of group 1A /group 1, so it is located in that group.

On the other hand, although the electronic configuration of helium is 1s², this element does not appear in group 2 of the periodic table of elements, but is placed in group 18. This is because it has the energy level complete, so it has the properties of a noble gas, that is, it is inert (it does not react), and it is a colorless and odorless monatomic gas.

In summary, in the periodic table hydrogen is placed in Group 1A (group 1) and helium is placed in Group 8A (group 18). The most likely reason for this is configuration, energy level and properties.
