Answer: 1) The element that would be the most effective at accepting electrons from another reagent is Cl.

2) The element that would be expected to be the best insulator is Cl (non-metal).

3) The element that is best able to form an ionic compound with sulfur is Rb.

Explanation:

Metals are the species which readily lose electrons in order to attain stability and non-metals are the species which readily accept an electron in order to attain stability.

Generally, metals on combining with non-metals lead to the formation of an ionic compound. For example, Rb_{2}S is an ionic compound where Rb is the metal and S is the non-metal.

Out of the given option Cl is highly electronegative in nature so it will readily accept an electron from a donor atom.

Insulator are the substances which do not allow electric current to pass through them. For example, non-metals are insulators.

Thus, we can match the elements below to the appropriate blanks in the following sentences.

1) The element that would be the most effective at accepting electrons from another reagent is Cl.

2) The element that would be expected to be the best insulator is Cl (non-metal).

3) The element that is best able to form an ionic compound with sulfur is Rb.

How much of a sample remains after three half-lives have occurred? 1/16 of the original sample 1/9 of the original sample 1/8 of
Drupady [299]
For this question, assume that you have 1 compound. This compound is divided in half once, so you are left with 0.5. That 0.5 that remains is divided in half again, this is the second half-life, and you are left with 0.25. The final half life involves dividing 0.25 in half, which means you are left with 0.125. For the answer to make sense, you need to know your conversions between decimals and fractions. To make it simple, if you have 0.125 and you times it by 8, you are left with your initial value of 1. Therefore, after three half-lives, you are left with 1/8th of the compound.

What energy transformation is involved in movement of muscles
ki77a [65]
When muscles are moved this represents a transfer from chemical energy to mechanical energy. As always, energy is conserved in the system. Kinetic energy can then come from the mechanical energy.

What mass in grams of MgSO4 is required to make 59.3 mL of 2.68 M<br> solution?
love history [14]

Answer:

Approximately 19.1\; \rm g.

Explanation:

<h3>Number of moles of formula units of magnesium sulfate required to make the solution</h3>

The unit of concentration in this question is "\rm M". That's equivalent to "\rm mol \cdot L^{-1}" (moles per liter.) In other words:

c(\mathrm{MgSO_4}) = 2.68\; \rm M = 2.68\; \rm mol \cdot L^{-1}.

However, the unit of the volume of this solution is in milliliters. Convert that unit to liters:

\displaystyle V = 59.3\; \rm mL = 59.3 \; \rm mL \times \frac{1\; \rm L}{1000\; \rm mL} = 0.0593\; \rm L.

Calculate the number of moles of \rm MgSO_4 formula units required to make this solution:

\begin{aligned}n(\rm MgSO_4) &= c \cdot V \\ &= 2.68 \; \rm mol \cdot L^{-1} \times 0.0593\; \rm L \approx 0.159\; \rm mol \end{aligned}.

<h3>Mass of magnesium sulfate in the solution</h3>

Look up the relative atomic mass data of \rm Mg, \rm S, and \rm O on a modern periodic table:

  • \rm Mg: 24.305.
  • \rm S: \rm 32.06.
  • \rm O: 15.999.

Calculate the formula mass of \rm MgSO_4 using these values:

M(\mathrm{MgSO_4}) = 24.305 + 32.06 + 4 \times 15.999 \approx 120.361\; \rm g \cdot mol^{-1}.

Using this formula mass, calculate the mass of that (approximately) 0.159\; \rm mol of \rm MgSO_4 formula units:

\begin{aligned}m(\mathrm{MgSO_4}) &= n \cdot M \\&\approx 0.159 \; \rm mol \times 120.361 \; \rm g \cdot mol^{-1} \approx 19.1\; \rm g\end{aligned}.

Therefore, the mass of \rm MgSO_4 required to make this solution would be approximately 19.1\; \rm g.
