Part A
den301095 [7]

Answer:

n_{Cl_2}=0.3molCl_2

Explanation:

Hello there!

In this case, according to the given chemical reaction whereas the sodium chloride is in a 2:1 mole ratio with chlorine, the required moles of the later are computed as shown below:

n_{Cl_2}=0.6molNaCl*\frac{1molCl_2}{2molNaCl}

So we cancel out the moles of NaCl to obtain:

n_{Cl_2}=0.3molCl_2

Best regards!

Which of the following best helps to explain why the electron affinity of Br has a greater magnitude than that of I?
tankabanditka [31]

The reason why  Br has a greater magnitude of electron affinity than that of I is that there is a greater attraction between an added electron and the nucleus in Br than in I.

In the periodic table, there are trends that increase down the group and across the period. Electron affinity is a trend that increases across the period but decreases down the group.

Recall that the ability of an atom to accept an electron depends on the size of the atom. The smaller the atom, the greater the attraction between an added electron and the nucleus.

Since Br is smaller than I, there is a greater attraction between an added electron and the nucleus in Br than in I which explains why Br has a greater magnitude of electron affinity than  I.

sample with masses 0.12g,1.8g, and 0.562g are mixed together the combind mass of the three samples expressed to the correct numb
allsm [11]

Answer:

2.5 g

Explanation:

Given data:

Masses of sample = 0.12 g, 1.8 g, 0.562 g

Combine mass of samples = ?

Solution:

When we add or subtract the values the number of significant figures after decimal in result must be equal to the given measurement having less number of decimal places.

0.12 g + 1.8 g + 0.562 g

2.482 g

In given three measurements 1.8 has less number of significant figure after decimal point which is only one digit. Thus the final value must contain one digit after decimal.

we will round of 2.482 g.

2.5 g

because the next digit after 4 is 8 that's why we will round 4 to 5.
