The formula of the chloride of M will be MCI2.
Answer:48kg of SiO2, 0.5kg of Al2O3, and 1.5kg of B2O3
Will be the final product
Explanation:
I) 96wt% of SiO2 will amount to 96/100*50 = 0.96*50=48kg of SiO2
ii) 1wt% of Al2O3 will amount to 1/100*50 = 0.01*50=0.5kg of Al2O3
III) 3wt% of B2O3 will amount to 3/100*50 = 0.03*50=1.5kg of B2O3..
The overall product form 48+ 0.5+1.5= 50kg
Answer:They are movement, nutrition, respiration, sensitivity, reproduction, excretion,and growth.
Explanation:
Answer:
1.387 moles
Explanation:
Step 1:
The balanced equation for the reaction. This is illustrated below:
4Fe + 3O2 —> 2Fe2O3
Step 2:
Determination of the number of mole of Fe in 155.321g of Fe. This can be achieved by doing the following:
Mass of Fe = 155.321g
Molar Mass of Fe = 56g/mol
Number of mole of Fe =?
Number of mole = Mass/Molar Mass
Number of mole of Fe = 155.321/56
Number of mole of Fe = 2.774 mol
Step 3:
Determination of the number of mole of rust (Fe2O3) produced. This is illustrated below:
From the balanced equation above,
4 moles of Fe produced 2 moles of Fe2O3.
Therefore, 2.774 moles of Fe will produce = (2.774 x 2)/4 = 1.387 moles of Fe2O3.
Therefore, 1.387 moles of rust (Fe2O3) is produced from the reaction
Answer:
The answer to your question is: letter D.
Explanation:
Double replacement reaction is when the cation of one reactant replaces the metal of the other reactant and vice versa.
a. 2SO2 + O2 —> 2S03 This is a combination reaction
b. Zn + Cu(NO3)2 → Zn(NO3)2 + Cu This is a single replacement reaction.
c. 2H2O2–> 2H2O + O2 This is a decomposition reaction
d . AgNO3 + NaCl → AgCl + NaNO3 This is a double replacement reaction
