Brass is an alloy of copper and zinc and is durable, malleable and sonorous.

<h3>What are alloys?</h3>

Alloys are products which are obtained from a mixture of two or more metallic elements.

Alloys are preferred to the individual elements because they combine the desirable properties of their component elements.

An example of an alloy is brass.

Brass is mixture of copper and zinc. It combines the shiny and anti-rust properties of zinc with the durability and sonorous property of copper.

It very sonorous and malleable and is used in many musical instruments.

In conclusion, alloys are produced by mixing two or more metals together.

What would cause the shape of a molecule to be tetrahedral?
Phantasy [73]

Answer:

A molecule is tetrahedral if the central atom has four bonds and no lone pairs.

Explanation:

A typical example is a molecule of methane (see image).

The electron pairs in the bonds repel the electrons in the other bonds, so they all try to get as far from each other as possible.

They can do this if the bonds point to the corners of a tetrahedron, with bond angles of 109.5°.

A 2.50 g sample of solid sodium hydroxide is added to 55.0 mL of 25 °C water in a foam cup (insulated from the environment) and
zlopas [31]

Answer:

37.1°C.

Explanation:

  • Firstly, we need to calculate the amount of heat (Q) released through this reaction:

<em>∵ ΔHsoln = Q/n</em>

no. of moles (n) of NaOH = mass/molar mass = (2.5 g)/(40 g/mol) = 0.0625 mol.

<em>The negative sign of ΔHsoln indicates that the reaction is exothermic.</em>

∴ Q = (n)(ΔHsoln) = (0.0625 mol)(44.51 kJ/mol) = 2.78 kJ.

  • We can use the relation:

Q = m.c.ΔT,

where, Q is the amount of heat released to water (Q = 2781.87 J).

m is the mass of water (m = 55.0 g, suppose density of water = 1.0 g/mL).

c is the specific heat capacity of water (c = 4.18 J/g.°C).

ΔT is the difference in T (ΔT = final temperature - initial temperature = final temperature - 25°C).

∴ (2781.87 J) = (55.0 g)(4.18 J/g.°C)(final temperature - 25°C)

∴ (final temperature - 25°C) = (2781.87 J)/(55.0 g)(4.18 J/g.°C) = 12.1.

<em>∴ final temperature = 25°C + 12.1 = 37.1°C.</em>
