The answer is CH₃O₆

An empirical formula is the simplest ratio. So, let's simplify the ratio

14 : 42 : 84

All numbers are divisible by 14, therefore:

14 : 42 : 84 = (14/14) : (42/14) : (84:14) = 1 : 3 : 6

So, it contains 1 C-atom, 3 H-atoms, and 6 O-atoms

The tiara worn by Kate Middleton for her wedding to Prince William of England contains 888 diamonds and belongs to the British m

allsm [11]

Answer:

The number of atoms in the gemstones of that tiara is $8.9125\times 10^{24} atoms$ .

Explanation:

Number of diamonds ion tiara = 888

Mass of each diamond = 1.0 carat = 0.200 g (given)

Mass of 888 diamonds in tiara:

$888\times 0.200 g=177.600 g$

Given that diamond is a form of carbon.

Atomic mass of carbon atom = 12 g/mol

Moles of 77.600 g of carbon = $\frac{177.600 g}{12 g/mol}=14.800 mol$

Number of atoms of carbon 14.800 moles:

$14.800 mol\times 6.022\times 10^{23} atoms =8.9125\times 10^{24} atoms$

The number of atoms in the gemstones of that tiara is $8.9125\times 10^{24} atoms$ .

A car's fuel efficiency is 39.0 miles per gallon. What is its fuel efficiency in kilometers per liter? (1.6094 km=1 mile)(1 gall

MrRa [10]

Answer:

the fuel efficiency in kilometers per liter is 16.561 kilometer per liter

Explanation:

The computation of the full efficiency in kilometers per liter is shown below:

39.0 miles ÷ gallon = (39.0 miles ÷ gallon) × (1.6094 km ÷ 1 miles) × (1 gallon ÷ 3.79 L)

Now cut the opposite miles and gallons

So, the fuel efficiency would be

= 16.561 kilometers per liter

Hence, the fuel efficiency in kilometers per liter is 16.561 kilometer per liter

Consider the reversible reaction A ( g ) − ⇀ ↽ − B ( g ) Which K values would indicate that there is more B than A at equilibriu

oksano4ka [1.4K]

Answer:

5000 and $8\times 10^{7}$ indicate that there is more B than A at equilibrium

Explanation:

For the given reaction: $K=\frac{[B]}{[A]}$

where [B] and [A] represents equilibrium concentration B and A respectively. K represents equilibrium constant

More B than A at equilibrium means, [B] > [A]

So, $K=\frac{[B]}{[A]}>1$

As, both 5000 and $8\times 10^{7}$ are greater than 1 therefore these two K values indicate that there is more B than A at equilibrium
