Answer:

 

14 ft 7 inches

step-by-step explanation:

since each model inch corresponds to 25 real inches, 7 model inches will correspond to

7×25" = 175"

at 12" per foot, that is 14 feet, 7 inches.

What is a reasonable estimate for the radius of an atom?
Romashka [77]

Answer is: 1 × 10⁻¹⁰ meter or 0.0000000001 meter.


The atomic radius is a measure of the size of the atom.

It is distance from the center of the nucleus of atom to the boundary of electron cloud.

The radius of atoms is between 30 and 300 pm (10⁻¹² m)  or between 0.3 and 3 angstroms (10⁻¹⁰ m). 

The radius generally decrease along each period of the Periodic table.

Ammonia is produced by the following reaction. 3H2(g) + N2(g) ---> 2NH3(g) When 7.00 g of hydrogen react with 70.0 g of nitro
ycow [4]
To determine the limiting reactant, we first calculate the number of moles of the reactant.

7.00 g H2 ( 1 mol / 2.02 g ) = 3.47 mol H2
70.00 g N2 ( 1 mol / 28.02 g) = 2.50 mol N2

From the balanced reaction, we see that there is a 3 is to 1 ratio of the reactants. So, for every 3 moles of H2 we need 1 mole of N2. Given the amount of reactant, for 2.50 moles of N2 we need 7.5 moles of H2 which obviously we have a lesser amount. Hydrogen is the limiting reactant.

True or false. it is safe to heat flammable liquids with a bunsen burner as long as it’s done in a fume hood.
Alborosie
I believe the answer is false. It is not safe <span>to heat flammable liquids with a bunsen burner even when it’s done in a fume hood. It is never recommendable to heat liquids that are flammable since it has a very high risk. Hope this answers the question.</span>
