Since both elements have a +1 charge, they cannot lose or gain electrons to form a bond. Plus they are both metals, so it wouldn't form a natural bond

Practice Problem: True Stress and Strain A cylindrical specimen of a metal alloy 49.7 mm long and 9.72 mm in diameter is stresse

amm1812

Answer:

The true stress required = 379 MPa

Explanation:

True Stress is the ratio of the internal resistive force to the instantaneous cross-sectional area of the specimen. True Strain is the natural log to the extended length after which load applied to the original length. The cold working stress – strain curve relation is as follows,

σ(t) = K (ε(t))ⁿ, σ(t) is the true stress, ε(t) is the true strain, K is the strength coefficient and n is the strain hardening exponent

True strain is given by

Epsilon t =㏑ (l/l₀)

Substitute㏑(l/l₀) for ε(t)

σ(t) = K(㏑(l/l₀))ⁿ

Given values l₀ = 49.7mm, l =51.7mm , n =0.2 , σ(t) =379Mpa

379 x 10⁶ = K (㏑(51.7/49.7))^0.2

K = 379 x 10⁶/(㏑(51.7/49.7))^0.2

K = 723.48 MPa

Knowing the constant value would be same as the same material is being used in the second test, we can find out the true stress using the above formula replacing the value of the constant.

σ(t) = K(㏑(l/l₀))ⁿ

l₀ = 49.7mm, l = 51.7mm, n = 0.2, K = 723.48Mpa

σ(t) = 723.48 x 106 x (㏑(51.7/49.7))^0.2

σ(t) = 379 MPa

The true stress necessary to plastically elongate the specimen is 379 MPa.

What atoms are likely to lose electrons to form cations

Anika [276]

Hey Jose! Thanks for asking a question here on Brainly.

⚪ Potassium
⚪ Magnesium
⚪ Sodium (aka Na)
⚪ Lithium (aka Li)

These are all atoms that are likely to lose electrons in order to form cations. Hope this helps. -UF aka Nadia

Practice Problem #1: __TiO2 + __Cl2 + __C __TiCl4 + __CO2 + __CO

ICE Princess25 [194]

Answer:

Explanation:

Given data:

Moles of Cl₂ react = ?

Moles of carbon = 4.55 mol

Solution:

Chemical equation:

2TiO₂ + 4Cl₂ + 3C → 2TiCl₄ + CO₂ + 2CO

Now we will compare the moles of Cl₂ with C.

C : Cl₂

3 : 4

4.55 : 4/3×4.55 = 6.1 mol

6.1 moles of chlorine will react with 4.55 moles of C.

Given data:

Mass of TiO₂ react = ?

Moles of carbon = 4.55 mol

Solution:

Chemical equation:

2TiO₂ + 4Cl₂ + 3C → 2TiCl₄ + CO₂ + 2CO

Now we will compare the moles of Cl₂ with C.

C : TiO₂

3 : 2

4.55 : 2/3×4.55 = 3 mol

Mass of TiO₂:

Mass = number of moles × molar mass

Mass = 3 mol × 79.87 g/mol

Mass = 239.61 g

Given data:

Molecules of TiCl₄ formed = ?

Moles of TiO₂ react = 115 g

Solution:

Chemical equation:

2TiO₂ + 4Cl₂ + 3C → 2TiCl₄ + CO₂ + 2CO

Number of moles of TiO₂:

Number of moles = mass/ molar mass

Number of moles = 115 g/ 79.87 g/mol

Number of moles = 1.44 mol

Now we will compare the moles of Cl₂ with C.

TiO₂ : TiCl₄

2 : 2

1.44 : 1.44

Molecules of TiCl₄:

1 mole = 6.022 × 10²³ molecules

1.44 ×6.022 × 10²³ molecules

8.672× 10²³ molecules

Differences and similarities in a mixture and compound

kumpel [21]

Mixture: matter than is composed of two or more substances that can be separated by physical means (ex; let's say you have a jar of red and blue marbles. this is a mixture. You can separate the colors with your hands (physical means.))

Compound: a substance in which two or more atoms are chemically combined in a fixed proportion (ex: water is a compound that consists of the element hydrogen and the element oxygen).
