The distance between two bonded atoms (the bond length), is usually in units of picometers, where 1.00 m = 1.00 x 1012 pm (or 1.

Answer:

7.52 × 10⁻¹⁴ mi

Explanation:

Step 1: Given data

Bond length between two carbon atoms (l): 121 pm

Step 2: Convert "l" to meters

We will use the conversion factor 1.00 m = 1.00 × 10¹² pm.

121 pm × (1.00 m / 1.00 × 10¹² pm) = 1.21 × 10⁻¹⁰ m

Step 3: Convert "l" to miles

We will use the conversion factor 1.00 mi = 1609.34 m.

1.21 × 10⁻¹⁰ m × (1.00 mi / 1609.34 m) = 7.52 × 10⁻¹⁴ mi

Need help with a chemistry question

DerKrebs [107]

Answer:

Sn2 mechanism reaction

Explanation:

In this case, we have a primary substrate (1-bromo-3,3-dimethylbutane). Because the leaving group "Br" is bonded to a primary carbon. Additionally, the nucleophile will come from the "NaI" (sodium iodide). This is an ionic compound, so, in solution, a cation and an anion would be produced. The anion $I^-$ would be the nucleophile.

Due to the primary substrate, we will have an Sn2 reaction. So, the attack of the nucleophile and the removal of the leaving group will take place in 1 step. Producing a "transition state" and finally and the final product (1-iodo-3,3-dimethylbutane).

See figure 1

The diving velocity of a falcon can reach 322 km/hr. If the falcon maintains this velocity for 7.2 seconds (0.002 hours), what w

Degger [83]

Multiply velocity and time and you get 0.644 km, but remember that displacement has a direction and so does velocity, so because velocity is positive in the direction that the falcon is going you have a positive displacement.

1.6x10^23 lead atoms. Find the weight in grams

Ber [7]

Moles of lead(Pb) = 1.6x10^23/6.02x10^23 = 0.265 moles.

Weight of lead = moles x atomic weight of lead
= 0.265x207.2
= 54.908 grams.

Hope this helps!

What’s the solution?

emmasim [6.3K]

Answer:

See balanced equations below

Explanation:

1. Mg(s) +2 HCL (aq) →MgCl₂ (aq) +H₂(g)

This is a single replacement reaction, involving an acid with a metal

2. 2Al(s) + 3H₂SO₄ (aq)→Al₂(SO₄)₃(aq) + 3H₂

3. 3 Zn (s) + 2H₃PO₄(aq)→ Zn₃(PO₄)₂ (aq) + 3H₂ (g)

4. 2Al(s) + 6HCL (aq)→2AlCl₃(aq) +3H₂ (g)

1. 2KOH(aq) + MgCl₂→Mg(OH)₂ (aq) + 2KCl (aq)

2. 3NaOH (aq)+ Al(NO₃)₃ (aq)→Al(OH)₃(s) + 3 NaNO₃(aq) ---this is a precipitation reaction

3. BaBr₂(aq) + H₂SO₄→BaSO₄ (s) + 2Br⁻(aq)

4. Na₂S + 2HCl → 2NaCl (aq) + H₂S (g)

5. 3CaCl₂ +2K₃PO₄→ Ca₃(PO₄)₂+6KCl

6.Ba(NO₃)₂ + (NH₄)₂CO₃→ 2(NH₄)⁺(aq) +BaCO₃(s)
