Answer:
The rate of reaction changes by a factor 6.
Explanation:
Given the reaction is first order.
Let us assume the initial concentration of 
is 
and the initial concentration of 
is 
.
So, we can write the rate of the reaction as
![R=k[A][B]](https://tex.z-dn.net/?f=R%3Dk%5BA%5D%5BB%5D)
Where,
is the rate of reaction. And 
is the rate constant.
Also, the initial concentration of has been increased by 
, and the initial concentration of was increased by factor 
.
So, we have
![R'=k[1.5A][4B]\\R'=6k[A][B]\\R'=6R](https://tex.z-dn.net/?f=R%27%3Dk%5B1.5A%5D%5B4B%5D%5C%5CR%27%3D6k%5BA%5D%5BB%5D%5C%5CR%27%3D6R)
We can see the rate of reaction changes by a factor 6.
True

i looked it up
Answer:Sources of lead emissions vary from one area to another. At the national level, major sources of lead in the air are ore and metals processing and piston-engine aircraft operating on leaded aviation fuel. Other sources are waste incinerators, utilities, and lead-acid battery manufacturers. The highest air concentrations of lead are usually found near lead smelters.
Explanation:
Answer:the initial composition of the reactants is
40cm^3 of CH4
40cm^3of H2
100cm^3 of H2O
Explanation:
Balanced reaction is
CH4 +H2+5/2O2______
CO2 +3H2O
Excess KOH at room temperature absorbs CO2 whose volume is given by 40cm^3 i.e the volume by which the solution decreases
So using Gay lussac combining ratio which states that gases combine in volumes that are in simple ratio to each other if gases.
Since CO2 in the equation is 1 mole
Means 1mole represent 40cm^3
So CH4:H2:O2 are in ratio of 1:1:5/2=(40:40:100)cm^3 respectively.
Answer: 0 I think
Explanation:
pretty sure its zero because i learned it last year but im in middle school so you might want to look it up.
