Which two properties apply to most elements that conducts heat: malleable, brittle, highly combustible, has free electrons

Chemistry
1 answer:
Airida [17]2 years ago
4 0

Answer:

malleable, has free electrons

Explanation:

The two properties that applies to most elements that conducts heat is that they are malleable and they have free electrons.

Most substances that conducts heat readily are metals.

  • Metals are held together by metallic bonding.
  • For a metallic bonds to form, there must be attraction between the positive nuclei of all the closely packed atoms in the lattice and the electron cloud jointly formed by all the atoms by losing their outermost shell electrons.
  • The physical properties of metals such as malleability and conduction is due  to this bond type.

Explain why you hear a “whoosh” sound when you open a can containing a carbonated drink. Which gas law applies?
Lana71 [14]

Carbonated drinks have the air under pressure so that carbon bubbles are forced into the drink, keeping it carbonated. So when you open a can, the air under pressure in the can comes out of the can at a high speed, making a "whooshing" sound. The gas law that applies to this concept is the Boyle's Law (PV=k or P1V1=P2V2).

What volume of Co2 (carbon (iv) oxide)
hram777 [196]

Answer:

2.1056L or 2105.6mL

Explanation:

We'll begin by calculating the number of mole in 10g of Na2CO3. This can be obtained as follow:

Molar mass of Na2CO3 = (23x2) + 12 + (16x3) = 106g/mol

Mass of Na2CO3 = 10g

Mole of Na2CO3 =.?

Mole = mass /molar mass

Mole of Na2CO3 = 10/106

Mole of Na2CO3 = 0.094 mole

Next, we shall determine the number of mole CO2 produced by the reaction of 0.094 mole of Na2CO3. This is illustrated below:

Na2CO3 + 2HCl —> 2NaCl + H2O + CO2

From the balanced equation above,

1 mole of Na2CO3 reacted to produce 1 mole of CO2.

Therefore, 0.094 mole of Na2CO3 will also react to 0.094 mole of CO2.

Next, we shall determine the volume occupied by 0.094 mole of CO2 at STP. This is illustrated below:

1 mole of a gas occupy 22.4L at STP. This implies that 1 mole CO2 occupies 22.4L at STP.

Now, if 1 mole of CO2 occupy 22.4L at STP, then, 0.094 mole of CO2 will occupy = 0.094 x 22.4 = 2.1056L

Therefore, the volume of CO2 produced is 2.1056L or 2105.6mL

Write balanced complete ionic equation for hcl(aq)+lioh(aq)→h2o(l)+licl(aq) express your answer as a chemical equation. identify
Svet_ta [14]

Explanation:

An equation is said to be balanced when the number of atoms on both reactant and product side are equal in number.

Whereas an equation where electrolytes in an aqueous solution are represented as dissociated ions is known as an ionic equation.

For example, HCl(aq) + LiOH(aq) \rightarrow H_{2}O(l) + LiCl(aq) can be represented in ionic form as follows.

   H^{+} + Cl^{-} + Li^{+} + OH^{-} \rightarrow H_{2}O(l) + Li^{+} + Cl^{-}

Now, cancelling the common ions present on both sides of the equation. The resulting, ionic equation will be as follows.

                 H^{+} + OH^{-} \rightarrow H_{2}O(l)
