Answer: The new volume is 72 ml

Explanation:

To calculate the final volume of the system, we use the equation given by Charles' Law. This law states that volume of the gas is directly proportional to the temperature of the gas at constant pressure.

Mathematically,

\frac{V_1}{T_1}=\frac{V_2}{T_2}

where,

V_1\text{ and }T_1 are the initial volume and temperature of the gas.

V_2\text{ and }T_2 are the final volume and temperature of the gas.

We are given:

V_1=217ml\\T_1=551^oC=(551+273)K=824K\\V_2=?\\T_2=0^0C=(0+273)K=273K

Putting values in above equation, we get:

\frac{217ml}{824K}=\frac{V_2}{273K}\\\\V_2=72ml

Thus the new volume is 72 ml

How many moles of solute would be needed to form two liters of a one molar
SCORPION-xisa [38]

Answer:

2 moles of solute.

Explanation:

Molarity is defined as number of moles of solute present in one litre of solution.

Hence one molar solution of NaCl means 1 mole of NaCl is present in 1 litre of solution.

Molarity = \frac{Number of moles of solute}{volume of solution in litres}

For 1 litre of solution 1 mole of solute is required to make a one molar solution.

Hence for 2 litres of solution we require 2 moles of solute to keep it one molar.

Is the autoionization of water endothermic or exothermic?
dexar [7]

it is an endothermic because water can not give off heat it can only take from others like if you were to boil water the water is endothermic and the heat is the exothermic

If 3.0 moles of x and 4.0 moles of y react according to the hypothetical reaction below, how many moles of the excess reactant w
Lesechka [4]
Firstly the limiting reactant should be identified. Limiting reactant is the reactant that is in limited supply, the amount of product formed depends on the moles present of the limiting reactant.

the stoichiometry of x to y = 1:2
1 mole of x reacts with 2 moles of y
if x is the limiting reactant, there are 3 moles of x, then 6 moles of y should react, however there are only 4 moles of y. Therefore y is the limiting reactant and x is in excess.
4 moles of y reacts with 2 moles of x 
since there are 3 moles of x initially and only 2 moles are used up, excess amount of x is 1 mol thats in excess.

What is one example of an everyday molecule?
Tamiku [17]

Answer:

Hydrogen

Explanation:

Just to provide some background, an element is a pure substance consisting of only one type of atom. An atom is the smallest constituent of matter. All elements are comprised of a single type of atom (e.g., gold is composed of gold atoms, helium of helium atoms, phosphorus phosphorus, and so on).

A molecule is a group of two or more atoms. They can be the same atom (homonuclear), such as or different atoms (heteronuclear).

Some examples of homonuclear molecules include:

Hydrogen  (H2)  

Nitrogen  (N2)  

Phosphorus  (P4)  

Some examples of heteronuclear molecules include:

Carbon dioxide  (CO2)  

Sulfuric acid  (H2SO4)  

Methane  (CH4)
