Answer:
<h2>The first thing to do here is to use the molarity and the volume of the initial solution to figure out how many grams of copper(II) chloride it contains.</h2><h2 /><h2>133</h2><h2>mL solution</h2><h2>⋅</h2><h2>1</h2><h2>L</h2><h2>10</h2><h2>3</h2><h2>mL</h2><h2>⋅</h2><h2>7.90 moles CuCl</h2><h2>2</h2><h2>1</h2><h2>L solution</h2><h2>=</h2><h2>1.051 moles CuCl</h2><h2>2</h2><h2 /><h2>To convert this to grams, use the compound's molar mass</h2><h2 /><h2>1.051</h2><h2>moles CuCl</h2><h2>2</h2><h2>⋅</h2><h2>134.45 g</h2><h2>1</h2><h2>mole CuCl</h2><h2>2</h2><h2>=</h2><h2>141.31 g CuCl</h2><h2>2</h2><h2 /><h2>Now, you know that the diluted solution must contain </h2><h2>4.49 g</h2><h2> of copper(II) chloride.

Answer:
Alkenes are <u>Very Reactive</u>.
Explanation:
Other options are incorrect because;
Saturated compounds are those hydrocarbons which contains only single bonds, while alkenes contain atleast one double bond.
Single bonds again stands for saturated compounds, hence it is false.
Alkene are reactive because the double bond has the potential to open by addition reaction. So electrophiles are readily added across double bond. This reactivity can also be explained by the exposure of nucleophilic double bond above and below the plane, which is highly exposed to incoming electrophiles.
I’m I’m pretty sure this is a combustion reaction, so that means the products would be CO2 + H2O.

Hello there!
In this case, when performing units conversions involving two proportional factors we need to make sure we first convert to the base unit and then to the target one; thus, since 1 kg = 1000 g and 1 g = 1000 mg, we set up the following expression:
Best regards!
Highest ionization energy to lowest: N, P, As, Sb.
