Answer: Polar covalent

Explanation:

a) A covalent bond is formed when an element shares its valence electron with another element. This bond is formed between two non metals.

Types of covalent bonds:

A polar covalent bond is defined as the bond which is formed when there is a difference of electronegativities between the atoms. Example: $SiO_2$

Non-polar covalent bond is defined as the bond which is formed when there is no difference of electronegativities between the atoms.Example: $N_2$

b) An ionic bond is formed when an element completely transfers its valence electron to another element. The element which donates the electron is known as electropositive element and the element which accepts the electrons is known as electronegative element. This bond is formed between a metal and an non-metal. Example: $NaCl$

3) How many moles are in 22 grams of argon?

professor190 [17]

Answer:

4) 0.5507 Mol Ar

5) 44.548 Mol AgNO3

6) 2.16107 Mol Li

Explanation:

Divide = grams to mol and mol to molecules

Multiply = molecules to mol and mol to grams.

3) 22 <em>g of Ar</em> 1 mol 22

-------------------- * ---------------------- = ------------ (turn to decimal) = 0.5507 Mol Ar

39.948 <em>g of Ar</em> 39.948

4) AgNO3 = (Ag; 39.948) (N; 14.007) (O^3; 48)

39.948 + 14.007 + 48 = 101.955

7.4 x 10^23 Mc 6.02 x 10^23 Mc

---------------------- * ------------------------- = 44.548 Mol AgNO3

1 mol

15g 1 Mol 15

------- * ------------------- = --------- (turn to decimal) = 2.16107 Mol Li

6.941 g of Li 6.941

egoroff_w [7]

0.06 has one significant figure (unless there are zeros written after it). So I would round the result to 6000. Some teachers prefer at least 2 significant figures though.

Grace [21]

Answer:

answer = 22.5m

Explanation:

using

$s = \frac{ {v}^{2} - {4}^{2} }{2a}$

s= (0²-21²)/2(-9.8)

s= -441/19.6

s= 22.5m

Producer gas is a fuel formed by passing air over red-hot coke (amorphous carbon). What mass of a producer gas that consists of

Karolina [17]

Producer gas is a fuel that is produced by burning biomass with an air deficit passed over red-hot coke (amorphous carbon). This gas is nothing but a mixture of gases such as hydrogen (H), carbon monoxide (CO), carbon dioxide (CO₂) and nitrogen (N₂).

The equation of producer gas is as follows -

CO₂ + 2N₂ (air) → CO + 2N₂

ΔH = -27.06 kcal

We know that,

1 Ton = 1000 kg

Mass of coke needed to form producer gas = 1.75 tons = 1750 kg

Given values,

Carbon monoxide (CO) = 25%

Carbon dioxide (CO₂) = 5%

Nitrogen (N₂) = 70%

One mole of carbon dioxide reacts with two moles of nitrogen to form one mole of carbon monoxide and nitrogen (producer gas).

We know that, 1 ton (1000 kg) of coke produces 470 Nm³ of producer gas, i.e.

470 × 4.359 = 2048.73 kg

1000 kg of coke produces = 2048.73 kg of producer gas

∴ 1 kg of coke produces = 2048.73 ÷ 1000 kg of producer gas

∴ 1750 kg of coke produces = 2048.73 × 1750 / 1000 = 3585.28 kg of producer gas.

Percentage yield = 87%

= 3585.28 × 87/100

= 3119.19 kg of producer gas

= 3.44 tons
