Explanation:
Objects or substances with their density greater than that of water will sink in it whiles those less than water will float on it.
From the question the object has a density of 3.4 g/mL.
Since it's density is greater than that of water the object will sink.
Hope this helps you
The density of water is 1.0 grams per milliliter then it will be sink in water
Density is a word we use to describe how much space an object or substance takes up in the volume and in relation to the amount of matter in that object or substance its mass) and another way to put it is that density is the amount of mass per unit of volume
Here given density is 1.0 grams per milliliter and it will be sink in water because the density of water in 1.0 g/ml and this object is more dense than water and the density of an object determines whether it will float or sink in another substance and an object will float if it is less dense than the liquid it is placed in and an object will sink if it is more dense than the liquid it is placed

<u>Answer:</u> The balanced chemical equation is written below.
<u>Explanation:</u>
There are 2 types of chemical reaction classified on the basis of heat change:
- <u>Endothermic reactions </u>: They are the reactions in which energy of products is more than the energy of the reactants. For these reactions, energy is absorbed by the system. The
comes out to be positive and is written on the reactants side. - <u>Exothermic reactions:</u> They are the reactions in which energy of reactants is more than the energy of the products. For these reactions, energy is released by the system. The comes out to be negative and is written on the product side.
We are given:
Moles of methanol = 2 moles
Moles of methane = 2 moles
Moles of oxygen gas = 1 mole
The chemical equation follows:
Hence, the balanced chemical equation is written above.
Answer:
Ratio between the reactants is 1:1, so if 2 moles of potassium sulfate react, The reaction consumes 2 moles of barium chloride
The reaction produces 2 moles of barium sulfate ( ratio is 1:1) and 4 moles of potassium chloride. (Ratio with this is 2:4)
Explanation:
This is the reaction:
BaCl₂(aq) + K₂SO₄(aq) → BaSO₄(s) + 2KCl(aq)
Ratio between the reactants is 1:1, so if 2 moles of potassium sulfate react, The reaction consumes 2 moles of barium chloride
The reaction produces 2 moles of barium sulfate ( ratio is 1:1) and 4 moles of potassium chloride. (Ratio with this is 2:4)
The mass of sodium sulfite that was used will be 1,890 grams.
<h3>Stoichiometric problems</h3>
First, the equation of the reaction:
The mole ratio of SO2 produced and sodium sulfite that reacted is 1:1.
Mole of 960 grams SO2 = 960/64 = 15 moles
Equivalent mole of sodium sulfite that reacted = 15 moles
Mass of 15 moles sodium sulfite = 15 x 126 = 1,890 grams
