Answer:
No, It will mean lot of rains but not every day
Explanation:
In wet tropical climates, the high clouds trap a lot of heat while balancing incoming and outgoing heat energy. When the number of heat trapping cloud remains very low, then the unstable cool air above the clouds cause lot of rain.
Hence, there will rain frequently but no everyday
Answer:
help me please help me
Explanation:
A tropical climate is a wet climate. Consider a city like Bogota, Colombia which has a tropical climate. Does a tropical climate being a wet climate mean that it will rain every day? Why or why not?
The acidic ingredient in vinegar is acetic acid. The pH of vinegar is around 2.4, and the molar concentration of acetic acid in vinegar is around 0.85 M. Based on this information, determine the value of the acid ionization constant, Ka, for acetic acid.
Answer: The value of acid ionization constant [tex]K_a[/tex] for acetic acid is [tex]1.87\times 10^{-5}[/tex]
Explanation:
[tex]CH_3COOH\rightarrow H^+CH_3COO^-[/tex]
cM 0 0
[tex]c-c\alpha[/tex] [tex]c\alpha[/tex] [tex]c\alpha[/tex]
So dissociation constant will be:
[tex]K_a=\frac{(c\alpha)^{2}}{c-c\alpha}[/tex]
Give c= 0.85 M and [tex]pH[/tex] = 2.4
[tex]pH=-log[H^+][/tex]
[tex][H^=}=c\times \alpha=10^{-2.4}=3.98\times 10^{-3}[/tex]
[tex]K_a=?[/tex]
Putting in the values we get:
[tex]K_a=\frac{(3.98\times 10^{-3})^2}{(0.85-3.98\times 10^{-3})}=1.87\times 10^{-5}[/tex]
Thus the value of acid ionization constant [tex]K_a[/tex] for acetic acid is [tex]1.87\times 10^{-5}[/tex]

Magnesium sulphate can be made from magnesium and dilute sulphuric acid.
This is the equation for the reaction.
Mg
+
H2SO4
MgSO4
+
H2
Calculate the mass of magnesium sulphate that would be obtained from 4g of
magnesium
(Show your working.)
Answer:
Reaction
Mg+H2SO4 ----》MgSO4+H2
so calculate the moles of magnesium first
moles of magnesium = given mass of mg/molar mass of magnesium
moles = 4/24.30
moles = 0.1646
One mole of magnesium produces one mole of magnesium sulphate
so 0.1646 moles of mg will produce 0.1646 moles of MgSO4
Mass of MgSO4 = 0.1646× 120.366
MgSO4 = 19.81 gm
conclusion the mass of magnesium sulphate that would be obtained from 4g of
magnesium is 19.81 gm!!

2. Energy that is stored in an object because of its temperature is called ___________________. *
Answer:
Thermal Energy
Explanation:
The thermal energy of an object increases as the temperature increases, causing atoms and molecules to move faster. When the temperature decreases, the thermal energy decreases, causing atoms and molecules to move slower. Another term for thermal energy is heat energy.
What types of matter consist of particles that are highly organized?
Answer: Solids
Explanation:
Solids have a definite volume and structure. These are comprised of atoms, ions, and molecules closely packed together giving a confined structure to the solids. The particles are bound with strong force of attraction. The particles in the solid are arranged in an repeated, orderly, and three dimensional pattern. Depending upon the substance of the solid the particles within the solid can be ions, atoms, and can be molecules.

What is the pH of a 1.0 x 10-4 M solution of KOH?
Answer:
pH = 10
Explanation:
KOH is a strong base; thus it will completely dissociate:
KOH -> K⁺ + OH⁻
Since it completely dissociates, the concentration of both K⁺ and OH⁻ will be the concentration of KOH given (1.0 x 10^-4 M).
We can then find pOH by taking the negative log of the OH⁻, or hydroxide, concentration:
pOH = -log[OH⁻] = -log[1.0 x 10^-4 M] = 4
At 25 degrees Celsius, pH + pOH = 14. If we solve for pH and then plug in our pOH, we get:
pH = 14 - pOH = 14 - 4 = 10
The pH of a 1.0 x 10^-4 M solution of KOH is thus 10.
what is einsteins theory of relativity?
Answer:
The laws of the universe are for all observers, and it was shown that the velocity of light in spacetime will be the same regardless of the subject's speed.
Explanation:
The principle outlines how things behave in time and space, so it could be used to model anything from black hole life to light shifting due to the gravitational, as well as the action of the terrestrial Planets in its orbit. Einstein's most popular hypothesis has far-reaching ramifications.
Place the characteristics for each phase of matter into the table where it belongs
Answer:
Solid- Definite shape
Solid and Liquid- Definite volume, Not easy to compress, if at all
Gas- No Definite Volume
Liquid and Gas- No Definite shape
The characteristics for each phase of matter in the table where it belongs are as follows:
Solids: Definite shape, very little particle motion. Liquids: Fluid motion. Gases: No Definite Volume, easily compressed. Solids and liquids: Definite volume, Not easy to compress, if at all. Liquids and Gases: No Definite shape, constant, fast particle motion. What are the different States of matter?The states of matter may be defined as the three distinct physical forms which matter can take in most environments. They are as follows:
Solid.Liquid.Gas.Each of the states of matter significantly possesses specific chemical and physical properties. For example, solids generally have a definite volume, are relatively rigid, and atoms or molecules are attached to each other very compactly.
Liquids possess a definite volume and have the ability to alter their shape through flowing. The atoms are loosely bonded to one another.
Gas has no definite volume or shape. This state of matter is easily compressed as well.
Therefore, the characteristics for each phase of matter in the table where it belongs are well described.

If people had not extracted fossil fuels from Earth to use as energy, would this carbon be "cycling" within the global carbon cycle we have defined today?
Answer: The answer is YES. There would still be recycling of carbon even if it wasn't extracted as fossil fuels for energy use.
Explanation:
Carbon is an element in the periodic table with the atomic number of 12. It has 4 electrons on its outermost shell in the electronic configuration. These are valence electrons which are used to form bonds in a wide range of both organic and inorganic compounds, giving rise to simply molecules like carbondioxide.
CARBON CYCLE is a natural process through which carbon and it's compounds are kept fairly constant through recycling. They are found in fossils fuels such as oil, coal, and natural gas. When these fossil fuels are burnt and used as energy, carbon is released in form of carbondioxide. This is just one of the ways carbon is returned to the atmosphere. Other ways include:
--> respiration of plants and animals
--> decomposition of organic substances
--> action of dilute acids and heat on trioxocarbonates (V) and hydrogen trioxocarbonates (IV).
Carbon is then removed from the atmosphere through:
--> plants in photosynthesis
--> rain water as weak trioxocarbonate (IV) acid.
Therefore, there would still be recycling of carbon even if it wasn't extracted as fossil fuels for energy use because the burning of fossil fuels is not the only way carbon is returned to the atmosphere during carbon cycle.

How many molecules of As4010 are in 6.2 mol of As4010?
How many moles are in 5.8 x 1024 atoms of C?
Answer:
No of moles of carbon = 9.63 mol
Explanation:
No of atoms of carbon = 5.8 × 10²⁴
Avogadro's no. = 6.022 × 10²³
No. of moles = No. of atoms / Avogadro's no.
N = 5.8 × 10²⁴ / 6.022 × 10²³
N = 9.63 mol
∴ No of moles of carbon = 9.63 mol

PLEASE HELP ME PLEASE
Answer:
Temperature and precipitation
Explanation:
They determine how quickly weathering will be, and what kind of organic material may be available on the inside of the soils.
Temperature and precipitation is the major determining factor in soil formation. They define the type of organic material that can be present inside the soils as well as how rapidly weathering will occur.
What is soil?The bioactive, porous media that has grown in the top layer of the Earth's crust is known as soil. Being a source of water as well as nutrients, a filter for harmful wastes, a site for their breakdown, and a participant inside the cycle of elements such as carbon through the planet's ecosystem, soil constitutes one of the main substrates of life on Earth.
It has changed as a result of weathering processes influenced by geographical, geologic, biological, and climatic factors. A practical understanding of soils including their management has also developed out of need since the development of agriculture with forestry in the eighth millennium BCE. Temperature and precipitation is the major determining factor in soil formation. They define the type of organic material that can be present inside the soils as well as how rapidly weathering will occur.
Therefore, temperature and precipitation is the major determining factor in soil formation.
