The (II) is a roman numeral indicating the oxidation number of a transition metal. It is used when you refer to the element/compound by name but does not show up in the formula.
Answer:
all of these are properties of metalloids
Answer:
A and B
Explanation: Dermal tissue functions to protect the plant from injury and water loss.
PV=nRT
p = 1,5atm = 1,5*101325 = 151987,5 Pa
V = 11,9l = 0,0119m3
n = ?
R = 8,314 J/mol*K
T = 20°C = 20+273 = 293K
pV=nRT
151987,5*0,0119 = n*8,314*293
1808,6513=n*2436,002 ||:2436,002
0,7425 = n >>> moles of CO2
1 mole of CO2 = 44g
1 mole of CO2--------------44g
0,7425 moles of CO2----------x
<u>x = 32,67g of CO2</u>
Answer: The rate will increase by a factor of 9.
Explanation:
Rate law says that rate of a reaction is directly proportional to the concentration of the reactants each raised to a stoichiometric coefficient determined experimentally called as order.
Given: Order with respect to = 2
Order with respect to = 1
Thus rate law is:
k= rate constant
It is given that the initial concentration of NO is tripled while all other factors stayed the same
Thus the rate will increase by a factor of 9.
