We can use the ideal gas
equation which is expressed as PV = nRT. At a constant pressure and number of
moles of the gas the ratio T/V is equal to some constant. At another set of
condition of temperature, the constant is still the same. Calculations are as
follows:
T1 / V1 = T2 / V2
V2 = T2 x V1 / T1
V2 = 303.15 x 300 / 333.15
<span>V2 = 272.99 cm³</span>
The elements found in a high portion of earths crust are Oxygen, Aluminum, Iron, Calcium, Potassium, Sodium and magnesium
Silk is made by moth larvae, asprin is derived from tree bark, nylon was made initially in a labratory, but asprin and even synthetic silk can be produced by chemist.
Answer:
a = double displacement(iii)
b = Single displacement (ii)
c = Synthesis reaction (i)
d = decomposition reaction (iv)
Explanation:
It's not that hard!
The reactants' concentration needs to be raised.
What factors influence rate of reaction?
The rate of the reaction controls how quickly the chemical reaction moves forward. The reaction's rate is influenced by a number of variables. These elements are:
(i) The concentration of the reactant: As the reactant concentration rises, the reaction rate does as well.
(ii) The reactant's nature. The condition, reactivity, or solution type of the reactants all have an impact on the reaction's pace.
(iii)The pressure of the gases: As the pressure of the gases involved in a reaction rises, so does its rate.
(iv) The surface area of the solids—As exposed surface area increases, so does the rate of reaction.
Therefore, if we to speed up the process, she should raise the reactant concentration since the more reactant molecules there are, the more molecules will actually collide, which will enhance the rate of the reaction.
