Chemical reaction: SO₄²⁻ + Ba²⁺ → BaSO₄.
m(sample) = 1,543 g.
m(BaSO₄) = 0,2243 g.
n(BaSO₄) = m(BaSO₄) ÷ M(BaSO₄).
n(BaSO₄) = 0,2243 g ÷ 233,4 g/mol.
n(BaSO₄) = 0,00096 mol.
n(BaSO₄) = n(SO₄²⁻).
ω(SO₄²⁻) = m(SO₄²⁻) ÷ m(sample).
ω(SO₄²⁻) = 0,00096 mol · 96 g/mol ÷ 1,543 g.
ω(SO₄²⁻) = 0,059 = 5,9%.
Answer:
El Niño is a climate cycle in the Pacific Ocean with a global impact on weather patterns. The cycle begins when warm water in the western tropical Pacific Ocean shifts eastward along the equator toward the coast of South America. Normally, these warm water pools near Indonesia and the Philippines.

Answer:
5 oz/cups
Explanation:
Because density is mass/volume, 10/2=5.
They would be very weird. 373 kelvin is just under 100 degrees Celsius, and baking anything at a hundred degrees Celsius would take a lot of time. Also, around 2 pounds equal one kilogram, meaning that 0.5 pounds is 250 grams. 2000 grams would be 4 pounds, so she definitely messed up the amount of chocolate chips. Since once cup is about 2.5 deciliters, 2 and a half cups would be 6.22 deciliters, meaning that she's a bit off, but it's not that big of a deal. They would be edible when done, but whether they would be eatable is up for debate.
If you were to make coyote population bigger it would first affect the rabbits because with there being more coyote's they have to bring more food for the pack and with the rabbits being hunted more and more the grass that the rabbits would eat, is not being eaten then the grass will grow more often and more longer.
That is the circle of life in the wild.
