erastova [34]

Answer:

The reaction is exothermic

The temperature of the water bath goes up

Explanation:

An exothermic reaction is one in which energy flows out of the reaction system.

In this case, the system is the reaction vessel while the surrounding is the water bath. We see in the question that 300.1J of heat flows out of the system during the reaction. This is heat lost to the surroundings showing that the reaction is exothermic.

As energy is lost to the surroundings, the temperature of the water bath rises accordingly.

How many moles of oxygen are needed for the complete combustion of 29.2 grams of acetylene?
podryga [215]

Moles of Oxygen= 2.8075 moles

<h3>Further explanation</h3>

Given

29.2 grams of acetylene

Required

moles of Oxygen

Solution

Reaction(Combustion of Acetylene) :

2 C₂H₂ (g) + 5 O₂ (g) ⇒ 4CO₂ (g) + 2H₂O (g)

Mol of Acetylene :

= mass : MW Acetylene

= 29.2 g : 26 g/mol

= 1.123

From equation, mol ratio of Acetylene(C₂H₂) : O₂ = 2 : 5, so mol O₂ :

= 5/2 x mol C₂H₂

= 5/2 x 1.123

= 2.8075 moles

An object has a mass of 20 kg and a volume of 5 mL. What is the object's density?
e-lub [12.9K]
Good grief, this stuff got caught in a black hole somewhere. It is terribly dense.
1 mL = 1 cc under normal conditions.

d = mass / volume
m = 20 kg
v = 5 mL

d = 20kg / 5 mL
d = 4 kg / mL
d = 4 kg / cc
