Answer:

First Statement is correct

Explanation:

An electron is transferred from sodium to chlorine and ionic bond is formed.

Hope it help!!

If sodium ( Na ) bonds with chlorine ( Cl ), then an electron is transferred from sodium to chlorine and an ionic bond is formed. Therefore, option A is correct.

The main interaction taking place in ionic compounds is ionic bonding, a form of chemical bonding that includes the electrostatic attraction between two atoms or ions with dramatically differing electronegativities.

When the ionic character is larger than the covalent character, i.e., when there is a significant difference in the electronegativity between the two atoms, the bond is more polar than when the electrons are divided more evenly in covalent bonding.

The ionic bond found in the salt sodium chloride is an illustration of this type of connection. The valence electron from sodium is transported to chloride's outer electron shell.

Thus, option A is correct.

Explanation:

Answer: There are [tex]47.6\times 10^{23}[/tex] molecules in 7.9 mol of [tex]H_2O_2[/tex]

Explanation:

According to avogadro's law, 1 mole of every substance occupies 22.4 L at STP and contains avogadro's number [tex]6.023\times 10^{23}[/tex] of particles.

1 mole of [tex]H_2O_2[/tex] molecule contains = [tex]6.023\times 10^{23}[/tex]  molecules

Thus 7.9 mole of [tex]H_2O_2[/tex] molecule contains = [tex]\frac{6.023\times 10^{23}}{1}\times 7.9=47.6\times 10^{23}[/tex] molecules

Thus there are [tex]47.6\times 10^{23}[/tex] molecules in 7.9 mol of [tex]H_2O_2[/tex]

its because during day time the ball becomes heated up and the air inside it try to come out as the heat air always try to go up swelling up the ball,

so in the evening when the air cools down the ball too cools down and air inside it also cools down making the ball feel soft,

Therefore, a football feels hard on a hot day but feels softer in the evening​

Answer:

Genes on the X chromosome are said to be X-linked. X-linked genes have distinctive inheritance patterns because they are present in different numbers in females (XX) and males (XY). X-linked human genetic disorders are much more common in males than in females due to the X-linked inheritance pattern.

Answer: The water vapor, carbon dioxide, methane, and other trace gases in the earth's atmosphere absorb the longer wavelength. These are all reasons why infrared waves hit the ground.

The water vapor, carbon dioxide, methane, and other trace gases in the earth's atmosphere absorb the longer wavelength. These are all reasons why infrared waves a part of electromagnetic spectrum  hit the ground.

The electromagnetic radiation consists of waves made up of electromagnetic field which are capable of propogating through space and carry the radiant electromagnetic energy.

The radiation are composed of electromagnetic waves which are synchronized oscillations of electric and magnetic fields . They are created due to change which is periodic in electric as well as magnetic fields.

In vacuum ,all the electromagnetic waves travel at the same speed that is with the speed of air.The position of an electromagnetic wave in an electromagnetic spectrum is characterized by it's frequency or wavelength.They are emitted by electrically charged particles which undergo acceleration and subsequently interact with other charged particles.

Answer:

Explanation:

follow the rule of "a weak acid can't make a stronger acid and weak base can't make a stronger base(it's pretty accurate for acid/salt reactions/replacemnts)" the last reactions won't work, but the second to last one will be kbr+pb(no3)2-> kno3 + PbBr2 (this is unballanced.) the first reaction will work. the second one i'm not too sure tbh, but i think it won't work since barium hydroxide's a weak base and if it were to react it would make koh, a super strong base

Answer:

3Ba(OH)2 + 2K3PO4 ----> 6KOH + Ba3(PO4)2

2KBr + Pb(NO3)2  ------> 2KNO3 + PbBr2

H3PO4 + 3KCl -----> K3PO4 + 3HCl

Explanation:

Answer: 190 g of magnesium chloride can be produced by reacting 2 moles of chlorine gas with excess magnesium bromide.

Explanation:

The balanced chemical reaction is;

[tex]Cl_2+MgBr_2\rightarrow MgCl_2+Br_2[/tex]

[tex]Cl_2[/tex] is the limiting reagent as it limits the formation of product and [tex]MgBr_2[/tex] is the excess reagent.

According to stoichiometry :

1 mole of [tex]Cl_2[/tex] produces = 1 mole of [tex]MgCl_2[/tex]

Thus 2 moles of [tex]Cl_2[/tex] will produce=[tex]\frac{1}{1}\times 2=2moles[/tex]  of [tex]MgCl_2[/tex]

 Mass of [tex]MgCl_2=moles\times {\text {Molar mass}}=2moles\times 95g/mol=190g[/tex]

Thus 190 g of magnesium chloride can be produced by reacting 2 moles of chlorine gas with excess magnesium bromide

Explanation:

Option D is the correct Lewis structure of ozone.

Ozone is known to be an allotrope of oxygen which has three atoms of oxygen.

In the Lewis structure of ozone, one pair of oxygen is actually double-bonded while the other is single-bonded. In this structure, two oxygen atoms carry charges. In the drawing the Lewis structure of ozone, we discover that one oxygen atom of the ozone has a -1 charge and while another oxygen atom of the ozone has a +1 charge.

Explanation:

water from rain and snow that travels to streams

Please help!

Water from a rain and snow that travels to streams are examples of run off. These natural processes are part of water cycle and balance the water content in the atmosphere and hydrosphere.

Water cycle is a geological phenomenon to balance the  water content in the atmosphere, hydrosphere and in the biosphere. The water bodies evaporate by the heat radiated by sun.

The air moisture can be restored to the land through the cooling of the vapor and pour as rain. This best illustrates the interaction between atmosphere and hydrosphere.

Rain, snow, sleet, or hail that reaches a surface stream without ever going below the soil's surface is referred to as surface runoff. It differs from direct runoff, which is runoff that directly reaches surface streams following rainfall or snowmelt. Hence option 4 is correct.

Answer:

pH = 11.30

Explanation:

pH is defined as -log [H⁺]

To find [H⁺] from [OH⁻] -Concentration of hydroxide ion-, we must use the equilibrium of water:

H₂O(l) ⇄ H⁺(aq) + OH⁻(aq)

Keq = 1x10⁻¹⁴ = [H⁺] [OH⁻]

[H⁺] = 1x10⁻¹⁴ / [OH⁻]

[H⁺] = 1x10⁻¹⁴ / 2x10⁻³M

[H⁺] = 5x10⁻¹²M

pH = -log (5x10⁻¹²M)
