How many grams of Cl are in 535 g of CaCl2?

1 answer:

8 0

To find the number of grams of chlorine in the compound calcium chloride, we need the molar masses of the substances and the ratio of the elements from the molecular formula.

535 g CaCl2 ( 1mol CaCl2 / 110.98 g <span>CaCl2</span> ) ( 2 mol Cl / 1 mol CaCl2 ) ( 35.45 g Cl / 1mol Cl) = 341.79 g Cl

Imagine that a new planet is discovered with two moons of equal mass: Moon A and Moon B. The mass of the new planet is greater t

kobusy [5.1K]

Answer: The gravitational pull on Moon B is greater than on Moon A because Moon B is closer to the new planet than Moon A.

Explanation:

The gravitational force exerted by the two objects on each other is inversely proportional to the square of the distance between the objects.

$F=G\frac{mM}{r^2}$

F = gravitational force or pull

G = gravitational constant on that planet

M = mass of the object-1

m = mass of object-2(Mass of Moon-A or Moon-B)

r = distance between two objects

$Force\propto \frac{1}{r^2}$

With decease in distance 'r' the force between the object increases or vice versa.So, from this we can say that the gravitational pull on Moon-B is more than the gravitational pull on Moon-A because the Moon B is closer than the Moon-A from the new planet.

Answer:

Explanation:

Al (s) + CuSO4 (aq) → Cu (s) + Al2(SO4)3 (aq)

2Al (s) + 3CuSO4 (aq) → 3Cu (s) + Al2(SO4)3 (aq).

In the process of oxidizing i− to i2, so42− is reduced to so2. how many moles of so2 are produced in the formation of one mole o

mafiozo [28]

The balance chemical equation is follow,

2 I⁻ + SO₄²⁻ + 4 H⁺ → I₂ + SO₂ + 2 H₂O

According to this reaction, 2 moles of I⁻ reacts with 1 mole of SO₄²⁻ to produce 1 mole of I₂ and 1 mole of SO₂.

Result:
So with the formation of 1 mole of I₂, 1 mole of SO₂ is produced.

Which of the following lists includes only molecules?

riadik2000 [5.3K]

The only list containing molecules is list #4

NaCl, N2, and H2O are all made up of more than one element, making them molecules. The other lists contain an element. Mg, He, and Fe are elements, not molecules.

Hope this helps!
