Answer:

7.5 % of Ag

Explanation:

Total mass of sterling silver chain is:

Mass of silver + Mass of copper

33.3 g Ag + 2.70g of Cu = 36 g

% of Silver is (mass of silver / total mass) . 100 →

(2.70 g / 36 g) . 100 → 7.5%

Answer:

92.5 % is silver

Explanation:

Step 1: Data given

Mass of silver = 33.3 grams

Mass of copper = 2.70 grams

Step 2: Calculate the total mass

Total mass = mass silver + mass copper

Total mass = 33.3 grams + 2.7 grams

Total mass = 36 grams

Step 3: Calculate % silver

% silver = (mass silver / total mass )*100%

% silver = (33.3 grams / 36.0 grams) *100%

% silver = 92.5 %

92.5 % is silver

1) A 10g sample of H2(g) reacts with a 22g sample of O2(g) according to
solmaris [256]

Answer:

H₂ is excess reactant and O₂ the limiting reactant

Explanation:

Based on the chemical reaction:

2H₂(g) + O₂(g) → 2H₂O

<em>2 moles of H₂ react per mole of O₂</em>

<em />

To find limiting reactant we need to convert the mass of each reactant to moles:

<em>Moles H₂ -Molar mass: 2.016g/mol-:</em>

10g H₂ * (1mol / 2.016g) = 4.96 moles

<em>Moles O₂ -Molar mass: 32g/mol-:</em>

22g O₂ * (1mol / 32g) = 0.69 moles

For a complete reaction of 0.69 moles of O₂ are needed:

0.69mol O₂ * (2mol H₂ / 1mol O₂) = 1.38 moles of H₂

As there are 4.96 moles,

<h3>H₂ is excess reactant and O₂ the limiting reactant</h3>

Which is the heaviest element produced in large stars by nuclear fusion near the end of their life cycle?
Rama09 [41]

Iron is the heaviest element produced in large stars by nuclear fusion near the end of their life cycle .

<h3>What do you mean by the nuclear fusion ?</h3>

Nuclear fusion is the process by which two light atomic nuclei combine to form a single heavier one while releasing massive amounts of energy.

The main advantage of nuclear fusion is it is safe source for the generation of electricity.

Characteristics of nuclear fusion -:

  • The main characteristic of nuclear fusion is that it involves formation of a singular particle from two or more atoms.

  • Unlike nuclear fission, nuclear fusion is common in nature- just hard to recreate.

  • Nuclear fusion typically produces few radioactive particles .

  • Fusion works by applying a great deal of pressure to overcome .

Hence ,Iron is the heaviest element produced in large stars by nuclear fusion near the end of their life cycle .

Calculate the energy required to move from solid water at 0 degrees C to liquid water at 0 degrees C
Serhud [2]

Answer:

Q = 334\,kJ

Explanation:

Let assume that 1 kilogram of water in solid state at one atmosphere of pressure. The fussion latent heat of 334\,\frac{kJ}{kg}, the heat required to change the phase of water is:

Q = m \cdot L_{f}

Q = (1\,kg)\cdot \left(334\,\frac{kJ}{kg} \right)

Q = 334\,kJ
