Is thiamine mononitrate an ionic bond or covalent bond?

Chemistry

It is a covalent bond. Whenever a compound uses such suffixes like mono, di, tri, tetra, and so on, it is a covalent compound- thus having covalent bonds.

Answer:

It's a <u>covalent bond</u>

Explanation:

The diference of electronegativity between the two atoms bonding can help you to decide if a bond is either <u>covalent</u> or <u>ionic</u>.

As shown in the figure, the oxygen atoms of the nitrate (left) will interact with the nitrogen atom of the thiamine(right).

The oxygen have an electronegativity of 3.5 (one of the most electronegative elements) and the nitrogen a 3.0

Being the difference: 3.5 - 3.0=0.5

Now, how this helps to decide the type of bond? For covalent bonds it's expected to have a electronegativity diffetence of < 1.5. On the other hand, for ionic bonds this value should be > 1.5

Write the electron configuration for Silicon
morpeh [17]

Answer:

Si₁₄ = 1s² 2s² 2p⁶ 3s² 3p²

Explanation:

Silicon is present in group 14 of periodic table.

It is blue-gray color metalloid.

Its atomic mass is 28 g/mol.

It is mostly used to make allow.

The most important alloy are Al-Si and Fe-Si. These are used to make different machine tools, transformer plates, engine etc.

Its atomic number is 14 and electronic configuration can be written as,

Electronic configuration:

Si₁₄ = 1s² 2s² 2p⁶ 3s² 3p²

The noble gas electronic configuration or abbreviated electronic configuration can also be written.

Si₁₄ = [Ne] 3s² 3p²

The atomic number of neon is 10. Its electronic configuration is,

Ne₁₀ = 1s² 2s² 2p⁶

That's why we write [Ne] for 1s² 2s² 2p⁶ in abbreviated electronic configuration of Si.

The specific heat of gold is 0.126 J/gºC. How much energy is released
Schach [20]

Explanation:

Specific heat capacity of gold (S)

= 0.126 J /kg°C

mass (m) = 350 g = 0.35 kg

difference in temperature (dt)

= 88.5°C - 24.6°C

= 63.9° C

Now

Energy released (Q)

= m*s*dt

= 0.35 * 0.126 * 63.9

= 2.81799 Joule

Hope it will help :)

If a 0.2g of oil consumed 1ml of sodium thiosulphate, calculate its iodine value and classify the oil?
marta [7]

Iodine value is a measure of the degree of unsaturation in fats and oils. It is essentially the number of grams of iodine consumed by 100 g of fat. If the iodine number is in the range of 0-70 then it is a fat, any value above 70 is considered an oil.

Formula:

Iodine number = (ml of 0.1 N Thiosulphate blank- ml of 0.1N thiosulphate test) * 12.7 *100/1000* wt of sample

vol of thiosulphate required to titrate test sample (given oil) = 1 ml

wt of sample = 0.2 g

Information on the volume of thiosulphate required to titrate the blank solution is essential for calculation.

Iodine number = (X-1.0) * 12.7 * 100/1000* 0.2 = (X-1.0)*6.35
