Shortly after the 2014 AFC Championship game between the New England Patriots and the Indianapolis Colts, the Patriots were accu

sed of deflating the game balls in order to make them softer and easier to catch and throw. The Patriots claimed that any decrease in the pressure of the footballs was due to a decrease in temperature during the game. Is the Patriots’ claim scientifically valid?
A.
Yes, because as the temperature of a gas decreases, pressure increases.

B.
No, because as the temperature of a gas decreases, pressure increases.

C.
Yes, because as the temperature of a gas decreases, pressure decreases.

D.
No, because as the temperature of a gas decreases, pressure decreases.

Given the following list of densities, which materials would float in a molten vat of lead provided that they do not themselves
vampirchik [111]

Answer:

b. glass and charcoal

Explanation:

Step 1: Given data

  • Density of Pb: 11.4 g/mL
  • Density of Glass: 2.6 g/mL
  • Density of Au: 19.3 g/mL
  • Density of charcoal: 0.57 g/mL
  • Density of platinum: 21.4 g/mL

Step 2: Determine which material will float in molten lead

Density is an intrinsic property of matter. Less dense materials float in more dense materials. The materials whose density is lower than that of lead and will therefore float on it are glass and charcoal.

3. A 4.00 gram sample of solid gold was heated from 274K to 314K. How much energy was involved?
MrMuchimi
Q = mcΔT = (4.00 g)(0.129 J/g•°C)(40.85 °C - 0.85 °C)
Q = 20.6 J of energy was involved (more specifically, 20.6 J of heat energy was absorbed from the surroundings by the sample of solid gold).

Carbon burns in the presence of oxygen to give carbon dioxide. Which chemical equation describes this reaction?
Phoenix [80]

Answer: Option (B) is the correct answer.

Explanation:

It is known that for writing a chemical reaction equation, reactants are written on left hand side whereas products are written on right hand side.

And in between reactants and products a forward arrow is placed pointing towards the products.

Therefore, the reaction for carbon burns in the presence of oxygen to give carbon dioxide will be written as follows.

          Carbon + Oxygen \rightarrow Carbon dioxide

Here, carbon and oxygen atoms are the reactants whereas carbon dioxide is the product.

1. Oxygen was discovered by Joseph Priestley in 1774 when he heated mercury (II) oxide, HgO, to decompose it to form its constit
Tomtit [17]

Answer:

1. 7.81 moles HgO

2. n = mass/molar mass = (4000 g)/(159.69 g/mol) = 25.05 mol.

Explanation:

How many moles of mercury (II) oxide are needed to produce 125 g of oxygen?

2HgO ==> 2Hg + O2  

125 g O2 x 1 mol O2/32 g x 2 mol HgO / mol O2 = 7.81 moles HgO

------------------------------------------------------------------------------------------------------------

If 4000 g of Fe2O3 is available to react, how many moles of CO are needed?

The no. of moles of CO are needed = 75.15 mol.

Fe₂O₃ + 3CO → 2Fe + 3CO₂,

It is clear that 1 mol of Fe₂O₃ reacts with 3 mol of CO to produce 2 mol of Fe and 3 mol of CO₂.

If 4.00 kg Fe₂O₃ are available to react, how many moles of CO are needed?

We need to calculate the no. of moles of 4.00 kg Fe₂O₃:

n = mass/molar mass = (4000 g)/(159.69 g/mol) = 25.05 mol.

Using cross multiplication:

1 mol of Fe₂O₃ need  → 3 mol of CO to react completely, from stichiometry.

25.05 mol of Fe₂O₃ need  → ??? mol of CO to react completely.

The no. of moles of CO are needed = (3 mol)(25.05 mol)/(1 mol) = 75.15 mol.
