Which sediments are carried by suspension?
Answer:
Sand and silt can be carried in suspension.
Explanation:
For example, sand and silt can be carried in suspension in river water and on reaching the sea bed deposited by sedimentation; if buried, they may eventually become sandstone and siltstone (sedimentary rocks) through lithification.

Venus and Mars?
Explanation:
PLEASE Answer asap! Compare two periodic families below. You must include at least two facts about each family. You may use any description of properties or periodic trends to help you.
Answer:
The alkali metals/group 1 are recognized as a group and family of elements. These elements are metals. Sodium and potassium are examples of elements in this family. Hydrogen is not considered an alkali metal because the gas does not exhibit the typical properties of the group. The largest family of elements consists of transition metals/group 3-12/group 3a. The center of the periodic table contains the transition metals, plus the two rows below the body of the table (lanthanides and actinides) are special transition metals. Even though both are metals, transition metals have higher melting points; they have higher density; they are less reactive with water; they react and form ions with different charges, but Group 1 metals only form 1+ ions.

Answer:
Element atom molar mass Total % composition
Na 1 23 40 57.5 %
O 1 16 40 40%
H 1 1 40 2.5 %
The given compound is NaOH.
Na : number of atom= 1
Molar mass= 23 g/mol
Total mass of NaOH = 40 g/mol
% composition by mass = [tex]\frac{\text {mass of atom}}{\text {Total mass}}\times 100=\frac{23}{40}\times 100=57.5\%[/tex]
O : number of atom= 1
Molar mass= 16 g/mol
Total mass of NaOH = 40 g/mol
% composition by mass = [tex]\frac{\text {mass of atom}}{\text {Total mass}}\times 100=\frac{16}{40}\times 100=40\%[/tex]
H : number of atom= 1
Molar mass= 1 g/mol
Total mass of NaOH = 40 g/mol
% composition by mass = [tex]\frac{\text {mass of atom}}{\text {Total mass}}\times 100=\frac{1}{40}\times 100=2.5\%[/tex]

b
Explanation:
b because it's a physical change
Your friend says, “chemical changes are caused by an input in energy. In physical changes, there is no transfer of energy” is your friend correct? Why or why not?
Answer: Your friend is incorrect.
Explanation: If we have an object or something that isn’t moving, (let’s say a notebook on a desk). If there is change, and the notebook moves, there is acceleration. Force = Mass times acceleration, f = m*a. There has to be a force, first of all. If you touched the notebook and moved it, some of your energy is transferred and now the notebook has kinetic energy. If our system is you and the notebook, the total energy doesn’t change. the energy is transferred, but doesn’t change. Your friend is not correct. Please give brainliest hope this helped!

Which statement describes sunspots? A.Sunspots have a bright white appearance. B.Sunspots occur in the radiative zone of the sun. C.Sunspots occur in areas of extremely low magnetic fields. D.Sunspots have lower temperatures than their surroundings.
Answer:
The statements that describe sunspots is;
D. Sunspots have lower temperatures than their surroundings
Explanation:
Sunspots is a phenomenon that involves temporary appearance of dark areas on the Sun's surface, which are regions of concentrated magnetic field flux which inhibit heat transfer by convection and are therefore cooler than other parts of the Sun. Due to the presence of magnetic field magnetic
Sunspots are temporary phenomena on the Sun's photosphere that appear as spots darker than the surrounding areas. They are regions of reduced surface temperature caused by concentrations of magnetic field flux that inhibit convection. Opposite magnetic polarity sunspots usually appear as a pair.
Therefore, the statement that best describe sunspots is that a sunspot is a region of reduced temperature compared to surrounding areas on the Sun's surface.

Answer:
0.67moles
Explanation:
The balanced equation of the chemical reaction given in this question is:
N2 + 3H2 → 2NH3
According to this equation, 3 moles of hydrogen gas (H2) produces 2 moles of ammonia gas (NH3)
Therefore, 1 mole of hydrogen gas (H2) will produce;
= 1 × 2/3
= 2/3
= 0.6666
= 0.67moles of ammonia (NH3)

Where are the places these minerals are found: Gold, Limestone and kaiolin.
Explanation:
Gold: The Kolar Gold Fields in Kolar used to be one of the major producers of gold in India, before it shut down. Presently the gold mines of Hutti and Raichur produce almost 84 per cent of the country’s gold. The other major centers of gold mining are Dharwad and Chitradurga. The gold mines produce about 3,000 kg’s of gold per annum. The district of Raichur is also famous for its silver deposits.
Limestone: It is another important mineral with an estimated 51,000 million tons. Karnataka has the largest limestone reserve in India. The districts of Gulbarga, Bagalkot, Belgaum, Shimoga and other Uttara Kannada districts are endowed with extensive high grade limestone. The present and consistent production of approximately 14 million tonnes provides for the cement plants in these districts.
China clay (kaolin) consisting dominantly of kaolinite is one of the most sophisticated industrial minerals with a host of applications, viz., in ceramics, refractories, paper coating, filler for rubber, insecticides, cement, paint, textiles, fertilizers and others including abrasives, asbestos products, fibreglass, chemicals, cosmetics, pharmaceuticals, electrical ware, foundry and glass.
The Department of Mining and Geology through their past investigation campaigns in parts of Kerala,identified two major china clay zones viz., the southern china clay zone between Thiruvananthapuram and Kundara (Thiruvananthapuram and Kollam districts) and the northern china clay zone between Kannapuram Madayi -Cheruthazham in Kannur district to Nileswarm - Manjeshwaram in Kasargod district. An estimated reserve of 172 million tonnes (probable reserve of 80 million tonnes and possible reserve of 92 million tonnes) of china clay of sedimentary and residual origin has been arrived at.
Kerala china clay is one of the finest quality clay and is world class. In fact, Kaolin marketed by English Indian Clays Ltd. (EICL), Thiruvananthapuram claims to have similar or even better properties compared to imported clays.

When performing a neutralization reaction, how should students test the solution to be sure which is the acid and which is the base?
Explanation:
La reacción entre un ácido y una base se llama neutralización. Cuando en la reacción participan un ácido fuerte y una base fuerte se obtiene una sal y agua. Si una de las especies es de naturaleza débil y la neutralización se produce en disolución acuosa también se obtiene su respectiva especie conjugada y agua.

Bloc ate 1 craft craft had 3 crafts. How much crafts are there?
what are the respective coefficients needed to balance the equation below _N2(g) + _H2(g) --> _NH3(g)
In the balanced equation, the mass of reactant is exactly equal to the mass of product. The respective coefficients needed to balance the equation is N₂(g) + 3H₂(g) ⇒ NH₃(g) .
What is balanced equation ?A chemical equation that is balanced has equal amounts of each element's atoms on both sides of the equation and conserves mass.
Because mass cannot be generated or destroyed, according to the rule of conservation of mass, a chemical equation must always be in balance.
The Law of Conservation of Mass is followed by a balanced equation. This is a crucial scientific guiding principle. Finally, a balanced equation enables us to forecast the quantity of reactants and products that will be produced. Sort of crucial if you're attempting to determine how much fuel to supply a spacecraft traveling to Mars
Thus, the balanced equation is N₂(g) + 3H₂(g) ⇒ NH₃(g) .
