In the close-pack model for hard spheres, there are repeating voids in the 3D lattice that are created. When a second layer is a

dded to the first close-packed layer there is a void directly under each sphere. The geometry of this void is _______. The other void has a(n) _________ geometry. These void spaces become important when one considers alloys. The type of alloy that is created when a different atom, that is relatively _______ (large/small), occupies some of the voids is called an ________ alloy. For instance, when iron is treated with Blank 5 steel is formed. It is more restant to sheering and bending as the included atoms strenthens the lattice.

fish give off the compound ammonia which has a pH above 7 to which class of compounds does ammonia belong
jasenka [17]
<span><u><em>Answer:</em></u>
The compound ammonia given by fish is alkaline

<u><em>Explanation:</em></u>
<u>We can classify elements/compounds based on their pH values into three types:</u>
<u>acids:</u> these are compounds having pH value lower than 7
<u>neutral:</u> these are compounds having pH value equal to 7
<u>alkalies:</u> these are compounds having pH values higher than 7

This is shown in the attached image

We are given that the pH of the compound ammonia generated by the fish is above 7.
According to the above explanation, compound ammonia would be an alkaline compound.

Hope this helps :)</span>

The age of fossils can sometimes be determined by radiometric dating, which is based on the constant rate of decay of radioactiv
True [87]
The age of the fossil given the present amount of Carbon-14 is given in the equation,
                               A(t) = A(o)(0.5)^t/h
where A(t) is the current amount, A(o) is the initial amount, t is time and h is the half-life. Substituting the known values to the equation,
                       A(t) / A(o) = 0.125 = (0.5)^(t/5730)
The value of t from the equation is 17190.
Thus, the age of the fossil is mostly likely to be 17190 years old.

3. The drop factor (gtts/cc) is the number of drops it takes to equal 1 cc for specific tubing in intravenous fluids. All
viva [34]

Answer:

30gtts/min

Explanation:

To solve this problem we need to divide the volume(mL) and time(min) then multiply by the drop factor. Note that 1hr = 60min.

120/60 * 15 = 30gtts/min

Best of Luck!
