Answer:

Zero order

Explanation:

Reaction rate for experiment 1 =

1.496 - 1.512 / 30 - 0 = - 5.3 * 10^-4 Ms-1

Reaction rate for experiment 2

2.552 - 2.584/60 - 0 =  - 5.3 * 10^-4 Ms-1

So,

Since the rate of reaction does not change with change in concentration of reactants (identified by the fact that the rates of reaction 1 and reaction 2 are the same), the reaction is zero order.

"how many grams of calcium are consumed when 156.8 ml of oxygen"
Akimi4 [234]
Your question is incomplete. However, I found a similar problem fromanother website as shown in the attached picture.

To solve this problem, you must know that at STP, the volume for any gas is 22.4 L/mol. So,

Moles O₂: 156.8 mL * 1 L/1000 mL* 1 mol/22.4 L = 0.007 moles
Mass calcium: 0.007 mol O₂ * 2 mol Ca/1 mol O₂ * 40 g/mol Ca =<em> 0.56 g Ca</em>

1. How many ATOMS of carbon are present in 7.48 grams of carbon monoxide ?
Salsk061 [2.6K]

Answer:

The answer is 1.61 × 10²³ atoms

Explanation:

To determine number of atoms, we will use the formula below

Number of atoms = number of moles (n) × avogadro's constant (6.02 x 10²³)

n was not provided, hence we will solve for n

n = mass/ molar mass

molar mass of carbon monoxide, CO (where C is 12 and O is 16) is 12 + 16 = 28

mass was provided in the question as 7.48

n = 7.48/28

n = 0.267

Hence,

number of atoms = 0.267 × 6.02 x 10²³

= 1.61 × 10²³ atoms
