A + BC ---> AB + C
So here one reactant (A) is accepting a group which is being given by another compound (BC) however the A is not giving any group / element or ion
So this single displacement
Similarly in the given reaction
the anion OH- is only being replaced
The element Ca accepts OH- and H2O loses the same group to form new element H2
So the correct answer is
Single replacement also known as single displacement.
A)2nd period - Li, Be, B,C,N,O,F,Ne
b)Metalls of the 2nd period are Li,Be
Ideal Gas Law
Given: P1= 1.25 atm P2= 95 atm
V1= 2.50 L
Unknown: V2=?
Formula: V=nRT/P; n = RT / PV
Solution: n = (0.0821 L x atm / K x mol) (285K) / (1.25 atm) ( 2.50L)
= 23.40 / 3.125
Answer: n = 7.49 moles of gas the balloon holds
<h2><u>Answer:</u></h2>
Lico. The stone was unclear range from the including territory. Between 130 million and 500 million years back, magma from volcanoes cooled to shape the stone that would advance toward getting to be Mt.
On Mount Lico in northern Mozambique is a site that few have had the enjoyment of seeing – a hid rainforest, verified by an unsafe float of shake. In spite of the way that the mountain was known to neighborhood individuals, the forested areas itself remained a secret until six years back, when Julian Bayliss spotted it on satellite imagery.
