Answer:
Subtract them.
Explanation:
''''"Since all number in scientific notation have base 10, we can always multiply them and divide them. To multiply two numbers in scientific notation, multiply their coefficients and add their exponents. To divide two numbers in scientific notation, divide their coefficients and subtract their exponents."""""
I was actually learned about this in school just found an source.
Answer:
18.87 g
Explanation:
80.1% of 23.56 g = 18.87 g is the mass of the silver
Answer:
The volume will be 18,23 ml.
Explanation:
We use the gas formula, which results from the combination of the Boyle, Charles and Gay-Lussac laws. According to which at a constant mass, temperature, pressure and volume vary, keeping constant PV / T. We convert the unit Celsius into Kelvin: 0 ° C = 273K, 44+273=317K, 17+273=290 K. The volume in L= 22/1000= 0,022L
P1xV1/T1= P2xV2/T2
V2= ((P1xV1/T1)xT2)/P2
V2=((0,905 atm x 0,022L/317K)x 290K)/0,999atm= 0,01823 L
0,01823x 1000= 18, 23 ml
We have to get the formula of the complex formed between Fe³⁺ and ethylenediamine.
The formula of the complex is: [Fe(<em>en</em>)₃]³⁺, where, <em>en</em> is abbreviation of ethylenediamine.
Ethylenediamine (<em>en</em>) is a bidentate ligand as it contains two donating sites (-NH₂ groups). Three ethylenediamine co-ordinate to central metal ion, Fe³⁺ and forms [Fe(<em>en</em>)₃]³⁺ with a co-ordination number of six.
