Answer:
The answer to your question is below
Explanation:
Balanced chemical reaction
Ca₃(PO₄)₂ + 3H₂SO₄ ⇒ 2H₃SO₄ + 3CaSO₄
To answer this question just calculate the molar mass of both reactants.
Molar mass of Ca₃(PO₄)₂ = (3 x 40) + (2 x 31) + (8 x 16)
= 120 + 62 + 128
= 310 g
Molar mass of 3H₂SO₄ = 3[(2 x 1) + (1 x 32) + (4 x 16)]
= 3[2 + 32 + 64]
= 3[98]
= 294 g
Conclusion
310 g of Ca₃(PO₄)₂ will react with 294 g of 3H₂SO₄
<h3><u>Answer;</u></h3>
B) a system is a group of objects analyzed as one unit
C) energy they moves across system boundaries is conserved
<h3><u>Explanation;</u></h3>
- System is a group of objects analyzed as one unit
.
- An open system is a system that freely exchanges energy and matter with its surroundings.
- A closed system is a system that exchanges only energy with its surroundings, not matter. An isolated system does not exchange energy or matter with its surroundings.
Answer: Order of the elements from most reactive to least reactive is:
Mg > Zn > Fe > H > Cu
Explanation: Reactivity of the elements is the tendency of the elements to loose or gain electrons with ease.
As, all the given elements are metals, so the metals which will loose electrons easily will be more reactive. To study the reactivity of metals, we use reactivity series.
The metals which are more reactive are placed on the top of the reactivity series and which are less reactive are placed at the bottom.
Hence, the order of the elements from most reactive to least reactive is:
Mg > Zn > Fe > H > Cu
Reactivity series is attached below.
Answer: In the Western United States and Canada, open range is rangeland where cattle roam freely regardless of land ownership. ... Land in open range that is designated as part of a "herd district" reverses liabilities, requiring an animal's owner to fence it in or otherwise keep it on the person's own property.
