We know that C has a formal charge of +4 while each O element
has a formal charge of -2, therefore the formal charge of X is:
X + 2 – 2 * 3 = 0
X + 2 – 6 = 0
X = 4
<span>So X has a group number of 4.</span>
Ferrous sulfate (FeSO4) is obtained by the reaction of aqueous ferric sulfate with gaseous sulfur dioxide and water according to the equation below:
Aqueous ferric sulfate = 
Gaseous sulfur dioxide = 
Water = 
Aqueous sulfuric acid = 
Aqueous ferrous sulfate = 
Thus, the balance equation becomes:
+ +

Answer:
7,01 g of indole-3-acetic acid
Explanation:
The milimolar concentration (mM) is defined as the ratio of milimoles per Liter of solution. 400mM means 400mmoles / L that is the same of <em>0,4mol / L</em>
100mL are <em>0,1L</em>. Using these values:
0,1L × (0,4mol / L ) = 0,04moles of indole-3-acetic acid.
As the MW of the molecule is 175,2 g/mol:
0,04mol × (175,2g / mol) = <em>7,01 g of indole-3-acetic acid</em>
<em></em>
Thus, <em>you need 7,01 g of indole-3-acetic acid to generate your solution</em>.
I hope it helps!
Answer:
1).....for the specific heat capacity(c) of water is 4200kg/J°C..
....guven mass(m)=320g(0.32kg)
...change in temperature(ΔT) =35°C
from the formula
Q=mcΔT
Q=0.32Kg x 4200kg/J°C x 35°C
Q=47,040Joules
Answer:
Q = 31798.4J = 31.79kJ
Explanation:
Heat energy (Q) = ?
Mass (m) = 152g
T1 = 24°C
T2 = 74°C
Specific heat capacity of water (c) = 4.184J/g°C
Q = Mc∇T
Q = 152 * 4.184 * (74 - 24)
Q = 635.968 * 50
Q = 31798.4J
Q = 31.79kJ
Heat required is 31.79kJ
