A package contains 1.33 lb of ground round. If there’s 29% fat, how many grams of fat are in the round?
OlgaM077 [116]

The answer is: 175 grams of fat are in the round.

m(ground round) = 1.33 ib.

First convert ib (pounds) to g (grams):

1 pound (lb) is equal to 453.592 grams (g).  

m(ground round) = 1.33 ib · 453.592 g/ib.

m(ground round) = 603.28 g.

ω(fat) = 29% ÷ 100%.

ω(fat) = 0.29; mass percentage of fat.

m(fat) = ω(fat) · m(ground round).

m(fat) = 0.29 · 603.28 g.

m(fat) = 175 g; mass of fat.

What features form when rocks bend?
bezimeni [28]
When the sedimentary layers of rocks are soft and under pressure they can be bent into curved structures called geosynclines. One theory is that heat partially melts the sedimentary layers of rocks allowing them to be bent into the curved shapes.

Hope this helps :)!

Ammonia is prepared industrially by the reaction:
Naya [18.7K]

Answer:

The correct option is d.

Explanation:

The reaction in the question is that for the formation of ammonia. The arrow in the reaction should be a reversible arrow. Because of the negative ΔH value, the forward reaction is exothermic while the reverse reaction is endothermic.

An increase in temperature of a system at equilibrium favors the endothermic reaction, hence the reverse reaction (the reactants) is favored. And when the reverse reaction is favored, more reactants are produced. Hence, product formation (at equilibrium) is not favored as the temperature is raised.
