2 C4H8O + 11 O2 —> 8 CO2 + 8 H2O
Answer:
Volume of the calcium hydroxide solution used is 0.0235 mL.
Explanation:
Moles of KHP =
According to reaction, 2 moles of KHP with 1 mole of calcium hydroxide , then 0.0330 moles of KHP will recat with ;
of calcium hydroxide
Molarity of the calcium hydroxide solution = 0.703 M
Volume of calcium hydroxide solution = V
Volume of the calcium hydroxide solution used is 0.0235 mL.
The question is: 10 g of carbonic acid H2CO3 are dissolved in 150 g of water. Determine the% m / m concentration of that solution?
Answer: The% m / m concentration of that solution is 6.66%.
Explanation:
Given: Mass of solute = 10 g
Mass of solvent = 150 g
Formula used to calculate the %m/m is as follows.
Substitute the values into above formula as follows.
Thus, we can conclude that the% m / m concentration of that solution is 6.66%.
A 780 gram element decays at a rate of 18% every minute. 780 elements are still missing (1-0.171) 19 .
Element:
<h3>What does that mean?</h3>
A basic object that is difficult to divide into smaller bits is described as an element. An element is a chemical that cannot be broken down by non-nuclear processes in physics or chemistry. A discrete component of a bigger structure or collection is referred to as an element in computers and mathematics.
<h3>Element and atom definitions?</h3>
The most basic form of a material is an element. In general, it cannot be streamlined or broken down into smaller parts. A constituent of an element is an atoms. A specific element only has one kind of atom per atom. Charged particles, neutrons, and electrons, which are particles, make up the remainder of an atom.

The new temperature of the gas is 115 °C
From the question given above, the following data were obtained:
- Initial temperature (T₁) = 25 °C = 25 + 273 = 298 K
- Initial pressure (P₁) = 0.96 atm
- New pressure (P₂) = 1.25 atm
- New temperature (T₂) =?
The new temperature of gas can be obtained as follow:
Therefore, the new temperature is 115 °C
