Answer:
Potassium nitrate
Explanation:
Because NO3 (nitrate) consists of 4 covalently bonds atom. NO3, incorporate of nitrate which share electrons then Ionic bonding occurred between K(as cation) NO3(as anion).
Answer:
2016 km
Explanation:
The escape velocity from Earth's surface is 
.
We need to find how many kilometers would a rocket travel in three minutes. It is a concept based on the definition of speed of an object.
Speed = distance per unit time
1 hour = 60 minutes
⇒ 3 minutes = 0.05 hour
1 m/s = 3.6 km/h
11200 m/s = 40320 km/h
So,
Hence, a rocket will travel 2016 km in 3 minutes.
Answer:
Explanation:
The period law state that when elements are listed in order of their atomic numbers, the elements fall into recurring groups, so that there is a recurrence of similar properties at regular intervals.
Na and K in the periodic table fall into the same group, this is because they both have one electrons in their outermost shell.
Na 11 -1s2 2s2 2p6 3s1
K 19 - 1s2 2s2 2p6 3s2 3p6 4s1
They share similar chemical and physical properties. Na and K are very reactive metals, they can loose/donate their outermost electron to non metals in other to attain stable octet state.
The form ionic compound when they react with non metals.
