Convert 34.4 lb to g. (1 lb = 453.6 g) A) 7.58 X 10-2 g B) 1.56 X 103 g C) 7.58 X 104 g D) 1.56 X 102 g E) 1.56 X 104 g

Answers

Answer 1

Answer:

E) 1.56x10⁴g

Explanation:

Pounds and grams are both units of mass. Pounds are used in UK and USA. Grams is the unit of mass used in the international system of units, SI.

To convert pounds, lb, to grams, g, we need the equivalence between these 2 units of mass:

1lb = 453.6g

That means 1lb weighs 453.6g. 34.4lb weigh:

34.4lb * (453.6g / 1lb) = 1.56x10⁴g. That means right option is:

E) 1.56x10⁴g

Which equation Best obeys the law of conservation of mass?

a) N2 + 3H2 —> 2NH3
b) H2 + O2 —> 2H20
c) 2Ag20 —> Ag2 + O2
d) N2 + H2 —> NH3

Answers

Answer:

N₂ + 3H₂ → 2NH₃

Explanation:

To obey the law of conservation of mass, the number of atoms on both sides of the expression, must be the same.

According to the law of conservation of mass "in a chemical reaction, matter is neither created nor destroyed but changed from one form to another".

To express this in chemical reaction, the number of atoms must be the same in going from reactants to products.

N₂ + 3H₂ → 2NH₃

We have 2 atoms of Nitrogen on both sides of the expression.

Also, we have 6 atoms of hydrogen on both sides.

Information to make scientifically supported judgments by describing the Importance of Ernest Rutherford's gold-foil experiment.

Answers

Answer:

Rutherford's experiment led to the rejection of JJ Thomson's raisin bundle model. In the experiment, a thin gold strip was bombarded with alpha particles. According to Thomson's atomic model, all alpha particles should have passed through the strip, but in this experiment it was found that some of the particles were reflected backwards. Based on his experiment, Rutherford published the result that almost the entire mass of an atom is concentrated in its nucleus. Rutherford's atomic model was later improved by Niels Bohr, who published the Bohr model.

Calculate the cash flow to stockholders excerpt from The Opal of Carmalovitchby Max PembertonDark was falling from a dull and humid sky, and the lamps were beginning to struggle for brightness in Piccadilly, when the opal of Carmalovitchwas first put into my hand. The day had been a sorry one for business: no light, no sun, no stay of the downpour of penetrating mist which hadbeen swept through the city by the driving south wind from the late dawn to the mock of sunset. I had sat in my private office for six long hours,and had not seen a customer. The umbrella-bearing throng which trod the street before my window hurried quickly through the mud and theslush, as people who had no leisure even to gaze upon precious stones they could not buy.

His dress was altogether singular. He had a black coat covering him from hisneck to his heels. But his hands were ungloved, and he wore a low hat, which might have been the hat of an office boy.

I will give brainliest too, please!excerpt adapted fromA Country Cottageby Anton ChekhovTwo young people who had not long been married were walking up and down the platform of a little country station. His arm was round her waist, her head was almost on his shoulder, and both were happy."How beautiful it is, Sasha, how beautiful!" murmured the young wife. "It all seems like a dream. How nice those solid, silent telegraph posts are! They add a special note to the landscape, suggesting humanity, civilization in the distance. Don't you think it's lovely when the wind brings the rushing sound of a train?"Three eyes of fire could be seen in the distance. The stationmaster came out on the platform."Let's see the train in and go home," said Sasha, yawning. "What a splendid time we are having together, Varya, it's so splendid, one can hardly believe it's true!""Look! look!" they heard from one of the carriages. "Varya and Sasha have come to meet us! There they are! . . . Varya! . . . Varya . . . Look!"Two little girls skipped out of the train and hung on Varya's neck. They were followed by a stout, middle-aged lady, and a tall, lanky gentleman with grey whiskers; behind them came two schoolboys, laden with bags, and after the schoolboys, the governess, after the governess the grandmother."Here we are, here we are, dear boy!" began the whiskered gentleman, squeezing Sasha's hand. "Sick of waiting for us, I expect! You have been pitching into your old uncle for not coming down all this time, I daresay! Kolya, Kostya, Nina, Fifa . . . children! Kiss your cousin Sasha! We're all here, the whole troop of us, just for three or four days. I hope we shan't be too many for you? You mustn't let us put you out!"At the sight of their uncle and his family, the young couple were horror-stricken. While his uncle talked and kissed them, Sasha had a vision of their little cottage: he and Varya giving up their three little rooms, all the pillows and bedding to their guests; the salmon, the sardines, the chicken all devoured in a single instant; the cousins plucking the flowers in their little garden. . . .And Sasha looked almost with hatred at his young wife, and whispered:"It's you they've come to see!""No, it's you," answered Varya, pale with anger.
