Answer:
<h2>The answer is 22 mL</h2>
Explanation:
The volume of a substance when given the density and mass can be found by using the formula
From the question
mass of CCl4 = 35.2 g
density = 1.60 g/mL
The volume is
We have the final answer as
<h3>22 mL</h3>
Hope this helps you
A) Na because it has a boiling point of 883 and alkali metals react with water.
B) Be because it is a metal in group 2 and period 2.
C) Ne because it is a noble gas with a boiling point of -246
The mass of Calcium required to complete this reaction is 4.008 g.
- Law of conservation of mass states that In a closed system, mass cannot be produced or destroyed, but it can be changed from one form to another.
- The mass of the chemical constituents before a chemical reaction is equal to the mass of the constituents after the reaction.
- In several disciplines, including chemistry, mechanics, and fluid dynamics, the idea of mass conservation is widely applied.
In the given reaction mass of product after completion of reaction is 13.614 g that means total mass of constituents before reaction should also be 13.614.
So,
mass of Ca + mass of O₂ + mass of S = mass of CaSO4
Ca + 6.400 g + 3.206 g = 13.614 g
mass of Ca = 13.614 - 9.606 = 4.008 g
Therefore, by law of conservation of mass 4.008 g of Ca is required for the completion of the reaction.

Chemical reaction is a process in which one set of chemical substances (reactants) is converted into another (products). It involves making and breaking chemical bonds and the rearrangement of atoms. Chemical reactions are represented by balanced chemical equations, with chemical formulas symbolizing reactants and products. For specific chemical reactants, two questions may be posed about a possible chemical reaction. First, will a reaction occur? Second, what are the possible products if a reaction occurs? This
This is true! Heterozygous would be Dd, and the dominant masks the recessive
