Laura is supplied with 5 bolts (B) and 12 nuts (N). She attached the nuts to the bolts in a 2:1 ratio (N2B). Which of the reactants will limit how much product can be formed?

A
Neither, they will both run out at the same time.

B
The nuts will run out first.

C
The bolts will run out first.

D
It is impossible to tell which one will run out first.

The bolts will run out first, so these will limit how much product can be formed.

(option C is correct)

Explanation:

Step 1: Data given

Number of bolts = 5

Number of nuts = 12

ratio N:B = 2:1

Step 2

Since the ratio N:B is 2:1 we have 2 nuts for each bolt

When we have 2 bolts we have 4 nuts

When we have 3 bolts we have 6 nuts

When we have 4 bolts we have 8 nuts

When we have 5 bolts we have 10 nuts

We don't have more bolts, but there are still 2 nuts left. This means the bolts will run out first, so these will limit how much product can be formed.

(option C is correct)

the leaf is an organ of a typical plant, and the main functions are to complete photosynthesis and allow the plant to exchange gas, just like how we have the respiratory system. leaves have the stomata, which collects maintains co2 and o2 levels. this is necessary for cell metabolism. the leaf also collects sunlight using chloroplasts. succinctly, leaves own a pivotal role in sustaining plant life.
