Answer:
A balanced equation is an equation for a chemical reaction in which the number of atoms for each element in the reaction and the total charge is the same for both the reactants and the products.
Explanation:
The temperature would be 30C if the water is at the same temp as the lab <span />
Answer:
A compound has atoms of different elements chemically joined together They can't be separated without a chemical reaction.
Answer: 7s
Explanation:
The order of the reaction is 2.
Integrated rate law for second order kinetic is determined using the formula
1/[At]=1/[Ao] +kt
But, [Ao] is the initial concentration = 1.50 mol/L
And [At] is the final concentration = 1/3 of initial concentration =1/3×1.5 = 0.5 mol/L
Rate constant, k = 0.2 L/mol*s
Using the formula
1/0.5=1/1.5+0.2t
Collecting like terms
1/0.5-1/1.5=0.2t
LCM = 1.5
3-1/1.5=0.2t
2/1.5=0.2t
Multiply both sides by 1/0.2
2/1.5×0.2=t
2/0.3=t
t=6.66s
t=7s
From the group I A of the periodic table of the element can the chemist infer the element.
