Name the type of bond between atoms in ammonia molecule. Give a reason for your answer
Likurg_2 [28]

Answer:

Covalent bonds are formed when electrons are shared between elements that are nonmetals. The ammonium ion, NH+4 , would have covalent bonds because both nitrogen and hydrogen are nonmetals. ... The rest of the bonds all contain electrons from both hydrogen and nitrogen, so they would be considered ordinary covalent bonds.

Which of the following is/are INCORRECT conversions in the metric system? Circle ALL that are false - there may be more than one
Artist 52 [7]

Answer:

(b) 50 mL = 0.50 L

Explanation:

Metric system is a measurement system that uses decimalized in all their factor, which mean every rank difference can be expressed as a factor of 10(deci=10). The decimalized number makes it easier to convert the unit, make the metric system easier to be learned and used.  

The Metric system will use a prefix to determine the factor, a kilo is 1000, mili is 1/1000, centi is 1/100, pico is 1/10^12.

(a) 1 km = 1000 m  

True, kilo is 1000

(b) 50 mL = 0.50 L

This option is false. mili is 1/1000, so 50/1000= 0.05 L

(c) 125 mm = 12.5 cm  

True, mili is 1/1000 while centi is 1/100.  

So 125mm will be: 125mm * 100mm/1000cm= 12.5cm

(d) 23 pm = 0.000  000  000  023 m

True, pico is 10^-12
