Answer:

200 lb•ft/s

Explanation:

From the question given above, the following data were obtained:

Force (F) = 2 tons

Time (t) = 5 mins

Height (h) = 15 ft

Power (P) =?

Next, we shall convert 2 tons to pound. This can be obtained as follow:

1 ton = 2000 lb

Therefore,

2 tons = 2 × 2000

2 tons = 4000 lb

Next, we shall convert 5 mins to seconds. This can be obtained as follow:

1 min = 60 s

Therefore,

5 mins = 5 × 60

5 mins = 300 s

Finally, we shall determine the power of the pump. This can be obtained as follow:

Force (F) = 4000 lb

Time (t) = 300 s

Height (h) = 15 ft

Power (P) =?

P = F × h / t

P = 4000 × 15 / 300

P = 60000 / 300

P = 200 lb•ft/s

Thus, the power of the pump is 200 lb•ft/s

How many moles of na2co3 would be needed to react with 750 ml of 0.250 m h2so4 solution?
olga2289 [7]

0.1875 mol of Na2CO3 needed to react with the 750 mL of 0.250 M H2SO4.

The given reaction between Na2CO3 and H2SO4 are already balanced.

Na2CO3 + H2SO4 → Na2SO4 + CO2.H2O

First, let us determine the number of moles of H2SO4.

Molarity (mol/L) = number of moles of H2SO4 / volume of H2SO4

0.250 M = number of moles of H2SO4 / [(750 mL)(1 L/1000 mL)]

number of moles of H2SO4 = 0.1875 mol

Then, let us determine the number of moles of Na2CO3 that would react with 0.1875 mol H2SO4.

number of moles of Na2CO3 = moles of H2SO4 * stoichiometric ratio

number of moles of Na2CO3 = 0.1875 mol H2SO4 * (1 mol Na2CO3/ mol H2SO4)

number of moles of Na2CO3 = 0.1875 mol Na2CO3

Fossil fuels are what resource
just olya [345]

Answer:

Fossil fuels are hydrocarbons, primarily coal, fuel oil, or natural gas, formed from the remains of dead plants and animals. In common dialogue, the term fossil fuel also includes hydrocarbon-containing natural resources that are not derived from animal or plant sources.

Explanation:

fossil fuels are continually formed by natural processes, they are generally classified as non-renewable resources because they take millions of years to form, and known viable reserves are being depleted much faster than new ones are generated.

Label the molecular shape around each of the central atoms in the amino acid glycine. hint
svetlana [45]

The Structure of Glycine is attached below and each central atom is encircled with different colors.

Molecular Shape around Nitrogen Atom (Orange):

As shown, Nitrogen is making three single bonds with two hydrogen atoms and one carbon atom hence, it has three bonded pair electrons and a single lone pair of electron. Therefore, according to VSEPR theory it has a tetrahedral electronic geometry but due to repulsion created by lone pair of electrons its molecular geometry becomes Trigonal Pyramidal.

Molecular Shape around Carbon Atom (Green):

As shown, Carbon is making four single bonds with two hydrogen atoms and one nitrogen atom one with carbon atom of carbonyl group hence, it has four bonded pair electrons. Therefore, according to VSEPR theory it has Tetrahedral geometry.

Molecular Shape around Carbon Atom (Blue):

As shown, Carbon is making two single bonds with oxygen and carbon atoms and a double bond with oxygen. Hence, it has a Trigonal Planar geometry.

Molecular Shape around Oxygen Atom (Red):

As shown, Oxygen is making two single bonds with one carbon atoms and one hydrogen atom hence, it has two bonded pair electrons and two lone pair of electrons. Therefore, according to VSEPR theory it has a tetrahedral electronic geometry but due to repulsion created by lone pair of electrons its molecular geometry becomes Bent.
