However, simple covalent compounds are generally named by using prefixes to indicate how many atoms of each element are shown in the formula. Also, the ending of the last (most negative) element is changed to -ide. The prefixes used are mono-, di-, tri-, tetra-, penta-, hexa-, and so forth.
Answer:
1.087 mi/min
Explanation:
Given data:
Speed of car in Km/h = 105
Speed of car in miles/min = ?
Solution:
It is given that one miles = 1.61 Km
while it is known that one hour = 60 minutes
Thus in order to convert the km/h into mi/min we will divide the given value by 96.561.
105 / 96.561
1.087 mi/min
Home safety is always very important, but it becomes a particular concern when a child enters a home. This type of safety includes many different considerations--you want to protect family members from deadly falls, fatal fires, hazardous ingestions, and more. Practicing safety at home is also an important consideration if you have elderly people in your home. It's even important if you have pets in your home. You have to be diligent to keep all dangerous items in your home out of the reach of people or animals it can harm. To maximize home accident prevention, make sure all child-safety locks are secure, all smoke and carbon monoxide detectors have fresh batteries, and numbers for emergency services and personnel and prominently and clearly displayed.
Since the iron is pure, we can look up its density value online and will always be true. This density value of iron is 7.87g/L. Now, we can use the density formula (D = m/V) and rearrange it to solve for V. This new equation is then V = m/D. Next, we plug in our known values and solve for V (5.00g/7.87g/L). This gives us our final answer of 0.635L (three sig figs due to the three sig figs in the provided mass).
Hope this helps!

Explanation:
The compound involved here is BF3(boron triflouride). The central atom is boron and it is surrounded by three fluorine atoms as shown in the image.
When a molecule has three electron domains in its structure, the molecule is trigonal planar. Hence, the molecular geometry of the compound is trigonal planar.
