18) Mg and S would be expected to react in a ratio of: (1:1, 2:1, 1:2 or 2:3)

Chemistry
1 answer:
lord [1]2 years ago
8 0

Answer:

1:1.

Explanation:

Hello!

In this case, since magnesium, in the form that is able to react with sulfur, has an oxidation state of 2+ and sulfur 2-, because they need to be different in order to form a suitable compound; due to that equality in their oxidation states, we expect they react in a 1:1 mole ratio, according to the following example:

Mg+S\rightarrow MgS

Best regards!

13. What is the atomic mass of an atom if its mass is approximately equal to the following? 1 a. that of carbon-12 b. 4.5 times
12345 [234]

The atomic mass of an atom if its mass is approximately equal to carbon-12 will be 12 and in case of 4.5 times carbon-12 will be 54

Atomic mass of an element is the average mass of the atoms of an element which are measured in atomic mass unit. Or we can also say that the atomic mass is actually the weighted mass is a weighted average of all of the isotopes of elements, in which the mass of each element is multiplied by the abundance of that particular isotope.

So the atomic mass of an atom if the mass is approximately equal to carbon-12 then the mass of the element will be equal to 12 as the atomic mass of carbon-12  is 12.

where as the atomic mass of an atom if its mass is approximately equal to 4.5 times as much as carbon-12 will be ⇒ 4.5×12= 54

What causes the jet stream to move farther south?
Anni [7]
<span>Jet streams are the major means of transport for weather systems.  A jet stream is an area of strong winds ranging from 120-250 mph that can be thousands of miles long, a couple of hundred miles across and a few miles deep.  Jet streams usually sit at the boundary between the troposphere and the stratosphere at a level called the tropopause.  This means most jet streams are about 6-9 miles off the ground. Figure A is a cross section of a jet stream.
</span>

The dynamics of jet streams are actually quite complicated, so this is a very simplified version of what creates jets.  The basic idea that drives jet formation is this:  a strong horizontal temperature contrast, like the one between the North Pole and the equator, causes a dramatic increase in horizontal wind speed with height.  Therefore, a jet stream forms directly over the center of the strongest area of horizontal temperature difference, or the front.  As a general rule, a strong front has a jet stream directly above it that is parallel to it.  Figure B shows that jet streams are positioned just below the tropopause (the red lines) and above the fronts, in this case, the boundaries between two circulation cells carrying air of different temperatures.
