Answer: from the lies this is synthesis reaction

Explanation:

It's also oxidation-reduction reaction. Li is oxidised and

H is reduced

The given reaction of lithium metal with water is an example of replacement reaction where, the OH group from water is replaced into LiOH.

A replacement reaction is a type of  reaction in which the an atom or group of one reactant is replaced into other reactant. Other type of reactions are combination reaction, decomposition etc.

In a combination reaction, two reactants combine together to form a product without any regrouping. In decomposition reaction a reactant is decomposing to form two or more constituent groups or molecules.

Combustion is the reaction of compound with oxygen to form water and carbon dioxide and synthesis is the making of new product using some reagents going through certain stages.

Hence, the reaction of lithium with water forming lithium hydroxide is a replacement reaction.

Answer:

D.phototropism

Explanation:

Phototropism is a type of tropism in which a plant or plant part responds to light. According to this question, a student wanted to investigate the effect of light on the growth of cress seedlings. The student used three different pots for the experiment.

Pot 1 was placed with light from above. Pot 2 was placed in a cupboard with no light. Pot 3 was placed in a window with light from one direction only. However, the image attached to this question shows that the plants in the different pots face different directions in response to light, which depicts phototropism

[tex]\boxed {\boxed {\sf 5.00 \ mol \ Ar }}[/tex]

Explanation:

To convert from mole to atoms, we must use Avogadro's Number: 6.022*10²³. This number tells us the particles (atoms, ions, molecules, etc.) in 1 mole of a substance. In this case, the particles are atoms of argon.

Let's create a ratio.

[tex]\frac {6.022*10^{23} \ atoms \ Ar}{1 \ mol \ Ar}[/tex]

Multiply by the given number of atoms.

[tex]3.01*10^{24} \ atoms \ Ar *\frac {6.022*10^{23} \ atoms \ Ar}{1 \ mol \ Ar}[/tex]

Flip the fraction so the atoms of argon will cancel.

[tex]3.01*10^{24} \ atoms \ Ar *\frac {1 \ mol \ Ar}{6.022*10^{23} \ atoms \ Ar}[/tex]

[tex]3.01*10^{24} *\frac {1 \ mol \ Ar}{6.022*10^{23}}[/tex]

[tex]\frac {3.01*10^{24} \ mol \ Ar}{6.022*10^{23}}[/tex]

[tex]4.998339422 \ mol \ Ar[/tex]

The original measurement of atoms has 3 significant figures, so our answer must have the same. For the number we calculated, that is the hundredth place. The 8 in the thousandth place tells us to round the 9 to a 0, which also rounds the 9 in the tenths place to a 0, then the 4 to a 5.

Answer: Yes, magnesium will replace hydrogen because magnesium is higher on the activity  series list.

Explanation:

A single replacement reaction is one in which a more reactive element displaces a less reactive element from its salt solution.  

A general single displacement reaction can be represented as :

[tex]X+YZ\rightarrow XZ+Y[/tex]

[tex]Mg+2HCl\rightarrow MgCl_2+H_2[/tex]

When magnesium is added to hydrochloric acid, magnesium being more reactive than hydrogen displaces hydrogen atom its salt solution and lead to formation of magnesium chloride and hydrogen gas.

Examples of herbivores are buffalo, elk, some bird species, mice, squirrels, rabbits, and many more.

To solve this, we must know each and every concept behind herbivores and  carnivores. Therefore, herbivores include cows, goats, giraffes, sheep, and zebras etc.

Herbivores, often known as herbivorous animals, are creatures that eat plants, leaves, fruits, and other plant-based foods for nourishment. They are classified as primary eaters and are found at levels 2 or above in the food supply chain.

Herbivores include cows, goats, giraffes, sheep, and zebras. Interestingly, there really are herbivores who specialize in eating on specific parts of the plant; for example, frugivores are herbivores that graze on fruits, whereas folivores are herbivore that eat on leaves.

Therefore, herbivores include cows, goats, giraffes, sheep, and zebras etc.

Answer:

0.47094837228 moles

Explanation:

silver nitrate=169.87g per mol

80/169.87 = 0.47094837228

Mole measure the number of elementary entities of a given substance that are present in a given sample. Therefore, 0.47moles of silver nitrate are there in 80.00 grams of silver nitrate.

The SI unit of amount of substance in chemistry is mole. The mole is used to measure the quantity or amount of substance. We know one mole of any element contains 6.022×10²³ atoms which is also called Avogadro number.

Mathematically,

number of moles of substance =given mass of substance ÷ molar mass of substance

Molar mass of 1 mole of silver nitrate=169.87g/mol

mass of silver nitrate= 80g

Substituting all the given values in the above equation, we get

number of moles of silver nitrate=80 ÷169.87

                                                        =0.47moles

Therefore, 0.47moles  of silver nitrate are there in 80.00 grams of silver nitrate.

Answer:

Manganese (II) Phosphate

Explanation:

Mn3(PO4)2 is the compound given in this question. Manganese is the metal and hence it will come first in the name. Along with the name of metal it is essential to determine the valency of the metals based on the compound structure.

Here 2 PO4 attaches with 3 Mn

Valence of PO4 is -3

So the total electrons contributed by PO4 is 3*2 = 6

Now Mn has 3 atoms in the compound. Thus, per atom the valency must be 2 in order to satisfy -6 charge of PO4

Thus, valency of Mn is 2

So, the name will be

Manganese (II) Phosphate.

According to the concept of Avogadro's number, there are 0.527×10²³molecules in  3.5 g of NaOH​.

Avogadro's number is defined as a proportionality factor which relates number of constituent particles with the amount of substance which is present in the sample.

It has a SI unit of reciprocal mole whose numeric value is expressed in reciprocal mole which is a dimensionless number and is called as Avogadro's constant.It relates the volume of a substance with it's average volume occupied by one of it's particles .

According to the definitions, Avogadro's number depend on determined value of mass of one atom of those elements.It bridges the gap between macroscopic and microscopic world by relating amount of substance with number of particles.

Number of atoms can be calculated using Avogadro's number as follows: mass/molar mass×Avogadro's number.Number of molecules= 3.5/40×6.023×10²³=0.527×10²³molecules .
