What happens to the buoyant force on an object as it is lowered into water?

1 answer:

8 0

The buoyant force is the upward force or thrust...Simply, consider immersing your hand into a bucket of water. What happens to it? It raises (a little). The raising is due to the buoyant force. Basically it is the upward force/thrust that acts on any object immersed into a fluid. Hence why things float when out in water. Hope this helped!!

How many grams of oxygen are produced when 7.65 moles of water is decomposed

maksim [4K]

Answer:

The answer to your question is 122.4 g of O₂

Explanation:

Data

mass of O₂ = ?

moles of H₂O = 7.65

Process

1.- Write the balanced chemical reaction

2H₂O ⇒ 2H₂ + O₂

2.- Convert the moles of H₂O to grams

molar mass of H₂O = 2 + 16 = 18 g

18 g of H₂O ---------------- 1 mol

x ----------------- 7.65 moles

x = (7.65 x 18) / 1

x = 137.7 g H₂O

3.- Calculate the grams of O₂

36 g of H₂O -------------------- 32 g of O₂

137.7 g of H₂O ------------------- x

x = (32 x 137.7) / 36

x = 122.4 g of O₂
