Group 17 is called the halogen family, and the group to its right is called the noble gases. How are these elements alike and ho
Vesnalui [34]

Explanation:

The halogen family and noble gases are similar in just one particular way, they are groups of non-metals. All members of these two groups are categorized as non-metals.

Here are some of the differences between them;

  • Halogens have 7 electrons in their outermost shell whereas noble gases have 8 electrons in theirs.
  • Halogens are highly reactive elements, noble gases are non-reactive.
  • Halogens are made up of electronegative elements where as noble gases are neither electropositive nor electronegative.

Where do reactions in a solid generally take place?
Sholpan [36]

Answer:

It's D.  On the surface of the solid.

Explanation:

If the reactant is a solid, the surface area of the solid will impact how fast the reaction goes. This is because the two types of molecule can only bump into each other at the liquid solid interface, i.e. on the surface of the solid. So the larger the surface area of the solid, the faster the reaction will be.

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.
