Why are metals alloyed?

1 answer:

5 0

Because alloys have qualities that are preferable to pure metals, almost all metals are utilised as alloys—that is, mixes of several elements. Alloying is done for a variety of purposes, the most common of which are to increase strength, corrosion resistance, or cost savings.

Pleasee help will name brainliest

zmey [24]

Answer:

0.125. work- divide the volume value by 1000

873. work- multiply the length value by 100

98100. work- Conversion factor: 1 kg = 100000 cg

1) Centigram = Kilogram * 100000

2) Centigram = 0.981 * 100000

3) Centigram = 98100

285.65. work- 12.5°C + 273.15 = 285.65K

446.85. work- 720K − 273.15 = 446.85°C

346.25. work- 73.1°C + 273.15 = 346.25K

Explanation:

i hope this helps:) brainliest plss??

Calculate the amount of heat required to raise the temperature of a 24 g sample of water from 9°C to 23°C.

borishaifa [10]

Answer:

1400KJ/mol⁻¹

Explanation:

Amount of heat required can be found by:

Q = m × c × ΔT

Where m is the mass, c is the specific heat capacity (4.2KJ for water) and ΔT is the change in temperature.

Q = 24 × 4.2 × (23 - 9)

= 24 × 4.2 × 14

= 1411.2KJ/mol⁻¹

= 1400KJ/mol⁻¹ (to 2 significant figures)

Place the following types of attraction weakest to strongest:

avanturin [10]

Answer: The order from weakest to strongest is:

$\text{dispersion forces}$

Explanation:

Dispersion force is the weakest intermolecular force. It is a temporary attractive force that come into action when the electrons in two neighboring atoms are at the positions which results in formation of temporary dipoles.

Dipole interaction is an attractive interaction between the positive end and negative end of the polar molecule.

Hydrogen bond is a weak bond between two adjacent molecules due to an electrostatic attraction between a hydrogen atom in a molecule with an electronegative atom of an adjacent molecule.

Single covalent bond is more stronger bond than the the interaction stated above because there is sharing of an electron between two atoms.

Ionic bond is the strongest bonds in which complete transfer of electrons is present. Due to high electronegativity difference between the bonded atoms there is a high electrostatic interaction between the oppositely charged ions which makes ionic bond strongest from all the other types of the bonds.

So, the order is:

$\text{dispersion forces}$
