Where are nonmetals located in the periodic table?



Question 8 options:

along the upper left side

in the middle

along the upper right side

along the bottom

Answers

Answer 1

Answer: They are located along the upper right side of the periodic table.

Explanation: Malleability is a physical property that some elements of matter have that can be broken down into sheets to give them a certain shape without breaking. This physical property belongs to plasticity. It is a characteristic that some metals have, sheets of said metal can be obtained. The heat needs to be increased, some examples are gold, platinum, zinc, tin, etc.

arrange the bromine-containing compounds cabr2, br2, asbr3, cbr4 in order of increasing normal boiling point.

Answers

Answer:

Br2, CBr4, AsBr3, CaBr2. this is the increasing order of boiling point

The arrangement of given compound in the increasing order of normal boiling point is Br₂ < CBr₄ < AsBr₃ < CaBr₂.

What is normal boiling point?

Norma boiling point of any liquid is that point where the vapor pressure is equal to the standard sea level atmospheric pressure.

And boiling point is directly proportional to the strength of bond which is present between the atoms of any compound.

As we know that ionic bond is the strongest bond and in CaBr₂ ionic bond is present so the boiling point of this compound will be highest.In AsBr₃, bromine is more electronegative than arsenic and arsenic also have one lone pair on it so some dipole moment develope in it and then this compound will have boiling point less than CaBr₂.CBr₄ is a covalent compound as in this compound bromine is present which is more electronegative but overall dipole moment of this compound is zero.Br₂ is also a covalent molecule and it has no dipole moment in it and have minimun boiling point among all compounds.

So, correct order will be Br₂ < CBr₄ < AsBr₃ < CaBr₂.

Jane made this picture to represent a chemical reaction:

Two circles, one white and the other gray are shown on the left. A small portion of the two circles overlap and the label below the circles is XY. An arrow pointing right is shown on the right of the overlapping circles. There are two circles on the right of the arrow, one white and the other gray, and there is a plus sign between them. The white circle is labeled X and the gray circle is labeled Y.

Which of the following statements best explains the type of chemical reaction represented by Jane's picture? (5 points)

It represents a synthesis reaction because one combined reactant forms multiple products.

It represents a synthesis reaction because the same atoms are present in the reactants and products.

It represents a decomposition reaction because one reactant breaks apart and forms two products.

It represents a decomposition reaction because the total mass of the products is less than the mass of the reactant.

Answers

The reaction represents a decomposition reaction because XY is broken into its constituents.

A decomposition reaction is one in which the reactant is broken up into its constituents. In this case, the reactant is XY. The reactant is shown in the left hand side. The reactant is broken up to yield the products. X and Y.

Since the reactant was broken up into the one white and one gray circles labelled X and Y, then the reaction is a decomposition reaction.

Knowing that the solubility of a salt at 80°C is 45g/100 g of H,O, calculate the mass of water required for dissolve 250 g of this salt at 80º C.​

Answers

The mass of water required will be approximately [tex] \bf = 555.6\: g [/tex].

To solve this question, just make a simple rule of three between the amount of salt dissolved at 80ºC and the mass of water:

[tex]\qquad[/tex] 45g of salt [tex] \sf \longrightarrow[/tex] 100g of H₂O

[tex]\qquad[/tex] 250g of salt [tex] \sf \longrightarrow[/tex] x g of H₂O

[tex]\qquad[/tex] [tex]\red{\twoheadrightarrow\bf x = 555.6\:g}[/tex]

Therefore, knowing that the solubility of a salt at 80ºC is 45g/100g of water (H₂O), the mass of water needed to dissolve 250g of this salt at 80ºC will be [tex] \red{\bf = 555.6\: g }[/tex]

1. Cu + 2AgNO3 ==> 2Ag + Cu(NO3)2 ... balanced equation. This is both a single replacement reaction and an oxidation reduction reaction.
Moles of Cu present = 19.0 g Cu x 1 mole Cu/63.55 g = 0.2990 moles Cu
Moles AgNO3 = 125 g AgNO3 x 1 mole AgNO3/169.9 g = 0.7357 moles AgNO3
Which reactant is limiting? It will be Cu because the mole ratio is 2 AgNO3 to 1 Cu and there is more than enough AgNO3. Thus, amount of Ag formed will depend on moles of Cu (0.2990)
Moles of Ag formed = 0.2990 moles Cu x 2 moles Ag/mole Cu = 0.598 moles Ag
Mass (grams) of Ag formed = 0.598 moles Ag x 107.9 g/mole = 64.52 g = 64.5 g of Ag (3 sig. figs.)

The chemical equation below shows the decomposition of ammonium nitrate (NH4NO3). NH4NO3 Right arrow. N2O 2H2O A chemist who is performing this reaction starts with 160. 1 g of NH4NO3. The molar mass of NH4NO3 is 80. 03 g/mol; the molar mass of water (H2O) is 18. 01 g/mol. What mass, in grams, of H2O is produced? 9. 01 18. 01 36. 03 72. 6.

Answers

The mass of water, H₂O produced from the reaction is 72.06 g

We'll begin by calculating the mass of NH₄NO₃ that reacted and the mass of H₂O produced from the balanced equation.

NH₄NO₃ —> N₂O + 2H₂O

Molar mass of NH₄NO₃ = 80.03 g/mol

Mass of NH₄NO₃ from the balanced equation = 1 × 80.03 = 80.03 g

Molar mass of H₂O = 18.01 g/mol

Mass of H₂O from the balanced equation = 2 × 18.01 = 36.02 g

From the balanced equation above,

80.03 g of NH₄NO₃ reacted to produce 36.02 g of H₂O

Finally, we shall determine the mass of H₂O produced by the reaction of 160.1 g of NH₄NO₃.

From the balanced equation above,

80.03 g of NH₄NO₃ reacted to produce 36.02 g of H₂O.

Therefore,

160.1 g of NH₄NO₃ will react to produce = (160.1 × 36.02) / 80.03 = 72.06 g of H₂O.

Thus, the mass of water, H₂O produced from the reaction is 72.06 g
