The paper clips will magnetically connect to the nail. With the copper wire wrapped around then nail, it makes a magnetic field that, when powered will cause metal objects to come toward it, hence why it is called an "electromagnet".

Hope this helps!!!

Fill in the Blank. 1. You want to be shielded from all three types of nuclear radiation. If you find shielding that blocks _____

Lena [83]

1. If you find shielding that blocks gamma radiation,then it will most likely also block the other two types. (as the hardest radiation)
2. When nuclear radiation enters the tube of a Geiger counter, it the excited atoms of the gas contained in the tube. (this type <span>deposits all energy into a single atom)</span>
3 The particles that make up protons and neutrons and are thought to be basic units of matter are <span>quarks.</span>

The ir spectrum of which type of compound will not show evidence of hydrogen bonding?

MArishka [77]

The IR spectrum of aldehyde compound will not show evidence of hydrogen bonding. The Infrared (IR) spectrum involves the interaction of infrared radiation with matter. It is used to study and identify chemicals and their properties. Evidence of hydrogen bonding is not shown due to lack of molecular contact.

How to Balance symbol equations?

Arlecino [84]

$2\; \text{Ca} + \text{O}_2 \to 2\; \text{CaO}$

Try the following steps:

Set the coefficient in front of the species with the greatest number of different atoms to one. In this question consider assigning Calcium Oxide $\text{CaO}$ a coefficient of one for containing two elements.
Deduce, using the rule of atomic conservation, the coefficient in front of other species. The product side of this equation contains one calcium $\text{Ca}$ and one oxygen $\text{O}$ atom, so should the product side. Thus assign calcium $\text{Ca}$ a coefficient of $1$ and oxygen gas a coefficient of $1/2$ - since $1/2 \; \text{O}_2 \times 2 \; \text{O atoms per O}_2 = 1 \; \text{O atom}$ : $1 \; \text{Ca} + 1/2 \; \text{O}_2 \to 1\; \text{CaO}$
In case any of the coefficient contains fractions, multiply all coefficients in the equation with the least common multiple of their denominators to convert the coefficients into whole numbers. In this example, multiple all coefficients by $2$ to deduce the equation shown at the beginning of this answer: $2\; \text{Ca} + \text{O}_2 \to 2\; \text{CaO}$ .
