Answer:
171.34 g/mol
Explanation:
Ba molar mass = 137.328 g/mol
O molar mass = 15.999 g/mol * 2 = 31.9980 g/mol
H molar mass = 1.008 g/mol * 2 = 2.0160 g/mol
137.328 + 31.9980 + 2.0160 = 171.3420 = 171.34 g/mol
There are 5 protons in Boron 1.
HISTORICAL INTRODUCTION.1<span> EVER since the establishment of the atomic theory by Dalton and Berzelius it was felt among chemists that there must be some relation between the atomic weights of the different elements and their properties. It was recognized very early that there exist groups of elements possessing related chemical and physical properties, and one of the earliest attempts to bring out this point is due to Dobereiner. In 1829 he tried to show that “many elements may be arranged in groups ()f three, in each of which the middle element has an atomic weight equal or approximately equal to the mean of the atomic weights of the two extremes.” As illustrations of this method of arrangement may be mentioned the following groups: Li, Na, K; Ca,Sr,</span>
Answer:
Explanation:
Ksp (BaCO₃) = 5.1 x 10⁻⁹
Ksp (CaCO₃) = 4.8 x 10⁻⁹
Ksp (BaSO₄) = 1.1 x 10⁻¹⁰ = .11 x 10⁻⁹
Since solubility product of BaCO₃ is greatest , its solubility is maximum .It is to be noted that all of them will be giving only two number of ions after dissolution in water .
BaCO₃ = Ba⁺ + CO₃⁻
Ksp = [ Ba⁺²] [ CO₃⁻² ]
= [ Ba⁺²]²
[ Ba⁺²] = √ Ksp
similarly we can find equations for others .
Answer:
conditioned
Explanation:
The best term to describe the behavior of the cat is <u>conditioned</u>.
<em>The cat has been conditioned to respond in a specific way to the pet carrier over time due to certain experiences - most likely, unpleasant ones. With repeated unpleasant experience associated with the per carrier, the cat has been conditioned to dislike/fear the pet carrier and thus, the recorded behavior. </em>
