1. As elements go across from left to right in a period,
mel-nik [20]

Answer:

decrease.

Explanation:

WHY? - As you go across a period, electrons are added to the same energy level. ... The concentration of more protons in the nucleus creates a "higher effective nuclear charge." In other words, there is a stronger force of attraction pulling the electrons closer to the nucleus resulting in a smaller atomic radius.

What is the oxidation state of an individual nitrogen atom in nh4oh ? express the oxidation state numerically (e.g., +1)?
Nonamiya [84]
In NH4OH, the compounds that make it up are NH4+ and OH-
Therefore N exists in the ammonium form.
In the ammonium ion 4H atoms are connected to N. 
 N is more electronegative than H, therefore when H bonds to N, H is the more positive atom therefore each H has a charge of +1, since there are 4 H atoms the charge contributed by the 4H atoms are +1 * 4 = +4
the overall charge of NH4 is +1
Charge of N (+) +4 =  +1
Charge of N = +1 - 4
Therefore oxidation state of N in NH4 is  = -3

There are 360 degrees in a circle. How many arcminutes will be in 86% of a circle?
Leokris [45]

Answer:

There are 18572.9 arcminutes in 86% of a circle.

Explanation:

The degrees in 86% of a circle is:

degrees = \frac{86}{100}*360 = 309.6 ^{\circ}

Now, we need to find the number of arcminutes in 309.6°:

arcminute = \frac{59.99 arcminute}{1 degree}*309.6 degrees = 18572.9

Therefore, there are 18572.9 arcminutes in 86% of a circle.

I hope it helps you!
