Explanation:

Answer:

i. The height of its jump is approximately 0.115 m

ii. The time of flight of its jump is approximately 0.306 seconds

iii. The range of its jump is approximately 0.795 m

Explanation:

The angle at which the grasshopper jumps, θ = 30°

The speed with which the grasshopper takes off, u = 3 m/s

i. The height of its jump 'h', is given by the following relation;

[tex]h = \dfrac{u^2 \times sin^2 \theta}{2 \times g}[/tex]

Where;

g = The acceleration due to gravity ≈ 9.81 m/s²

Therefore;

[tex]h \approx \dfrac{3^2 \times sin^2 (30^{\circ})}{2 \times 9.81} = \dfrac{25}{218} \approx 0.115[/tex]

The height of its jump, h ≈ 0.115 m

ii. The time of flight of its jump, 't', is given as follows;

[tex]The \ time \ of \ flight, \, t = \dfrac{2 \times u \times sin \theta}{ g}[/tex]

Therefore;

[tex]t \approx \dfrac{2 \times 3 \times sin (30 ^ {\circ})}{ 9.81} = \dfrac{100}{327} \approx 0.306[/tex]

The time of flight of its jump, t ≈ 0.306 seconds

iii. The range of the jump is given by the following projectile motion equation for the range as follows;

[tex]R = \dfrac{u^2 \times sin (2 \times \theta)}{ g}[/tex]

Therefore;

[tex]R \approx \dfrac{3^2 \times sin (2 \times 30^ {\circ})}{ 9.81} = \dfrac{41659} {52433} \approx 0.795[/tex]

The range of the jump, R ≈ 0.795 m.

Answer:

Examples of physical change include changes in the size or shape of matter. Changes of state—for example, from solid to liquid or from liquid to gas—are also physical changes. Some of the processes that cause physical changes include cutting, bending, dissolving, freezing, boiling, and melting.

Answer:

the answer is 1.1grams is the currect ans

According to the law of conservation of mass, 1.1 grams of calcium carbonate are formed  if 2.2 grams of CaO are used for this reaction.

According to law of conservation of mass, it is evident that mass is neither created nor destroyed rather it is restored at the end of a chemical reaction .

Law of conservation of mass and energy are related as mass and energy are directly proportional which is indicated by the equation E=mc².Concept of conservation of mass is widely used in field of chemistry, fluid dynamics.

Law needs to be modified in accordance with laws of quantum mechanics under the principle of mass and energy equivalence.This law was proposed by Antoine Lavoisier in the year 1789.If 56 g CaO gives 46.2 g calcium carbonate then  2.2 g CaO will give 2.2×46.2/56=1.1 g.

Answer: The molality of naphthalene solution is 0.499 m

Explanation:

Density is defined as the ratio of mass and volume of a substance.

[tex]\text{Density}=\frac{\text{Mass}}{\text{Volume}} [/tex] ......(1)

Given values:

Volume of carbon tetrachloride = 500 mL

Density of carbon tetrachloride = 1.60 g/mL

Putting values in equation 1, we get:

[tex]\text{Mass of carbon tetrachloride}=(1.60g/mL\times 500mL)=800g[/tex]

Molality is defined as the amount of solute expressed in the number of moles present per kilogram of solvent. The units of molarity are mol/kg. The formula used to calculate molarity:

[tex]\text{Molality of solution}=\frac{\text{Given mass of solute}\times 1000}{\text{Molar mass of solute}\times \text{Mass of solvent (in g)}}[/tex] .....(2)

Given values:

Given mass of naphthalene = 51.2 g

Molar mass of naphthalene = 128.17 g/mol

Mass of solvent = 800 g

Putting values in equation 2, we get:

[tex]\text{Molality of naphthalene}=\frac{51.2\times 1000}{128.17\times 800}\\\\\text{Molality of naphthalene}=0.499m[/tex]

Hence, the molality of naphthalene solution is 0.499 m

Answer: The reaction of formation of ions by fluorine and potassium​ is [tex]K^{+} + F^{-} \rightarrow KF[/tex].

Explanation:

Atomic number of potassium is 19 and its electronic distribution is 2, 8, 8, 1. So, in order to attain stability it needs to lose 1 electron due to which it forms [tex]K^{+}[/tex] ion.

Atomic number of fluorine is 9 and its electronic distribution is 2, 7. In order to attain stability it needs to gain one electron and hence forms [tex]F^{-}[/tex] ion.

Therefore, when both these ions come in contact with each other then it leads to the formation of KF compound.

The reaction equation for this is as follows.

[tex]K^{+} + F^{-} \rightarrow KF[/tex]

Thus, we can conclude that the reaction of formation of ions by fluorine and potassium​ is [tex]K^{+} + F^{-} \rightarrow KF[/tex].

Explanation:

According to Avogadro's law, the volume of a given mass of gas is directly proportional to the number of molecules of gas present at constant temperature and pressure.

Hence; V1/n1 = V2/n2

The implication of this is, if there were X molecules present and the volume of the balloon is halved, the number of molecules of gas present is also halved. So, we now have X/2 number of gas molecules present in the balloon.

This is in accordance with the statement of Avogadro's law.

Carbon monoxide

Explanation:

The molecule has the carbon and oxygen atoms in equal amounts.

Answer:

Atoms and molecules can be deflected by magnetic fields - provided the atom or molecule is first turned into an ion. Electrically charged particles are affected by a magnetic field although electrically neutral ones aren't. The atom or molecule is ionised by knocking one or more electrons off to give a positive ion.

Explanation:

Please Mark me brainliest

The atom must first be ionized.

The mass spectrometer is an important analytical tool in chemistry. It is used to identify atoms and molecules.

However, the atom or molecule to be analysed must first be converted into an ion.

This happens when the instrument imparts an electrical charge to the molecule or atom  then the electrically charged ions are read as electrical current.  The ion is accelerated towards a detector which analyses the deflected ions.
